Why GAO Did This Study: 

The federal government is the nation’s single largest energy consumer, 
spending approximately $17 billion in fiscal year 2007. A number of 
statutes and executive orders have established and revised goals 
directing agencies to reduce energy consumption and greenhouse gas 
emissions—such as carbon dioxide, which results from combustion of 
fossil fuels and natural processes, among other things—and increase 
renewable energy use. GAO was asked to determine the extent to which 
(1) federal agencies met energy efficiency, greenhouse gas emission, 
and renewable energy goals in fiscal year 2007; (2) federal agencies 
have made progress in each of these areas in the recent past; and (3) 
six selected agencies are poised to meet energy goals into the future. 
For this review, GAO, among other things, conducted site visits for six 
agencies and reviewed the Department of Energy’s (DOE) annual reports 
to Congress on federal energy management. 

What GAO Found: 

Based on draft DOE data, most of the 22 agencies reporting to DOE for 
fiscal year 2007 met energy goals for energy efficiency, greenhouse gas 
emissions, and renewable energy. Specifically, all but one agency met 
the energy efficiency goal. Three of these agencies would not have met 
the goal through reductions in energy intensity—the amount of energy 
consumed per gross square foot—alone; they also used credits for the 
purchase of renewable energy or source energy to help meet the goal. 
Because the greenhouse gas emission goal is tied to the energy 
efficiency goal, the same number of agencies met the greenhouse gas 
emission goal, while 17 of the 22 agencies met the renewable energy 
goal. 

Determining the extent to which agencies have made progress over time 
toward the goals is problematic due to key changes in the goals—as 
specified in statute and executive order—and how progress is measured. 
For example, the energy efficiency goal changed the types of buildings 
included and the baseline year against which progress was measured. The 
greenhouse gas emissions goal also changed, from a measure of 
greenhouse gas emissions to a measure of energy intensity; this change 
makes it problematic to compare performance before and after the 
change. Moreover, GAO found that a goal based on energy intensity is 
not a good proxy for emissions because a reduction in energy intensity 
does not always result in lower greenhouse gas emissions. Although 
there is no consensus on a best measure at present, alternative 
measures are in use that may better track agencies’ greenhouse gas 
emissions than the current measure based on energy intensity. 

Agencies’ prospects for meeting energy goals into the future depend on 
overcoming four key challenges. First, the six agencies GAO 
reviewed—the departments of Defense (DOD), Energy (DOE), and Veterans 
Affairs (VA); the General Services Administration (GSA); the National 
Aeronautics and Space Administration (NASA); and the U.S. Postal 
Service (USPS)—had long-term plans for achieving energy goals that 
lacked key elements, such as plans that outline agencies’ strategies 
that are linked to goals and provide a framework for aligning 
activities, processes, and resources to attain the goals of the plan. 
Second, investment in energy projects competes with other budget 
priorities, causing agency officials to increasingly rely on 
alternative financing mechanisms—contracts with private companies that 
pay for energy improvements. However, as past GAO work has shown, 
agencies entering into these contracts could not always verify whether 
money saved from using less energy was greater than projected costs and 
may yield lower savings than if timely, full, and upfront 
appropriations had been used. Third, agencies face challenges in 
obtaining reliable energy consumption data but are taking steps to 
collect more reliable data. Finally, facilities may lack staff 
dedicated to energy management and may find it difficult to retain 
staff with sufficient energy expertise; however, agency officials are 
participating in training and implementing initiatives for energy 
management personnel. 

What GAO Recommends: 

GAO recommends that DOE (1) reevaluate the current measure for 
greenhouse gas emissions and establish one that more accurately 
reflects agencies’ performance in reducing these emissions, and (2) 
finalize and issue guidance for agencies’ use in developing long-term 
plans that contains key elements for meeting current and future energy 
goals. GSA, NASA, and USPS concurred; VA neither agreed nor disagreed; 
and the other agencies did not comment.

The federal government is the nation's single largest energy consumer, 
spending approximately $17 billion in fiscal year 2007 on energy for 
buildings and vehicles, according to the most recent available data. 
This total represents almost 1 percent of all federal expenditures for 
2007. And these costs have been rising in recent years. According to 
the Department of Energy (DOE), from 2003 to 2007, the cost per unit of 
energy increased by 59 percent in constant 2007 dollars. In light of 
these energy price increases, congressional interest in making the 
federal government more energy efficient has grown as well. 

Since the 1970s, federal statutes and executive orders have set and 
revised a number of goals for changing the way federal agencies use or 
obtain energy. Most recently, the Energy Policy Act of 2005 (EPAct 
2005) and two executive orders set energy goals for federal agencies. 
As figure 1 shows, the goals address such areas as improving energy 
efficiency, reducing greenhouse gas emissions[Footnote 1], and 
increasing the use of renewable energy source[Footnote 2]s. For 
greenhouse gas emissions, Executive Order 13423 (E.O. 13423) lays out a 
direction linked to the energy efficiency goal rather than a numerical 
goal specific to emissions.[Footnote 3] These goals apply to a range of 
buildings, from standard office buildings to more energy-intensive 
buildings, such as industrial or laboratory buildings.[Footnote 4] In 
January 2007, E.O. 13423 revoked Executive Order 13123 (E.O. 13123), 
which had guided agencies in energy conservation efforts since June 
1999 and added energy goals to those in EPAct [Footnote 5]2[Footnote 
6]005., In addition, the statute and E.O. 13423 set goals for agencies 
to reduce petroleum consumption and increase the use of alternative 
fuels in vehicle fleets. Some types of federal buildings are excluded 
from these goals, such as buildings for which national security is 
overwhelmingly the primary function and prevents the implementation of 
energy efficiency measures or prohibits reporting of energy data 
because it would pose a demonstrated security risk. 

Figure 1: Changes to Energy Efficiency, Greenhouse Gas Emissions, and 
Renewable Energy Goals, Fiscal Years 1999-2007: 

This figure is a table with illustrations showing changes to energy 
efficiency, greenhouse gas emissions, and renewable energy goals,

consumes, the following amounts are to be from renewable electric 
energy: not less than: 3% in FY 2007-2009, 5% in FY 2010-2012, 7.5% in 
FY 2013 and beyond (no new source requirement – i.e., projects built 
after a certain date). 

Statute or executive order: E.O. 13423: (January 24, 2007); 
Building categories: All buildings; 
Energy efficiency: Reduce energy intensity by(i) 3% annually through

reduction of energy intensity of (i) 3% annually through the end of FY 
2015 or (ii) 30% by the end of FY 2015,relative to the agency’s energy 
use in 2003; 
Renewable energy: At least half of the renewable energy required in 
EPAct2005 consumed by an agency in a fiscal year should come from new 
renewable resources (those placed in service after January 1, 1999).

Note: Buildings meeting certain criteria--such as those with a national 
security function--may be excluded from meeting the energy goals. 

[A] Section 503 of E.O. 13123 directed the Secretary of Energy, in 
collaboration with the heads of other agencies, to develop goals for 
the amount of energy generated at federal facilities from renewable 
energy technologies. In July 2000, the Secretary approved the goal 
specifying that 2.5 percent of building electricity consumption shall 
come from renewable energy projects built after 1990. 

[End of figure] 

As figure 1 shows, EPAct 2005 changed the energy efficiency goal in 
E.O. 13123. Further, the most recent executive order, E.O. 13423, 
increased the reduction in energy intensity called for in EPAct 2005. 
Energy intensity is the amount of energy consumed--measured in British 
thermal units (Btu)--per gross square foot. The energy goals in place 
for the agencies in fiscal year 2007 are the following: 

* Energy efficiency. Reduce energy intensity by 6 percent, from a 2003 
baseline. EPAct 2005 required a 2 percent annual reduction in energy 
intensity starting in 2006, which would have resulted in a total of 4 
percent for 2007. However, the new executive order was implemented mid- 
fiscal year 2007, and the implementation instructions for the new order 
directed agencies to reduce energy intensity by 6 percent for fiscal 
year 2007, from a 2003 baseline. After 2007, E.O. 13423 directs 
agencies to reduce energy intensity by 3 percent annually, or a total 
of 30 percent by the end of fiscal year 2015, relative to a 2003 
baseline. Agencies could count two types of credits toward their energy 
efficiency goal in fiscal year 2007: credits for purchasing renewable 
energy and source energy credits. To calculate credits for purchasing 
renewable energy, DOE subtracts a purchase from the amount of energy 
the agency consumes in measuring its progress toward the goal.[Footnote 
7] This credit will be phased out completely by fiscal year 2012. 
Source energy credits take into account the use of site energy--energy 
used only at a particular site--and source energy--the energy consumed 
in producing and delivering energy to the site. For example, an agency 
can obtain source credits if it generates electricity on-site using 
natural gas and recovers the heat used to generate the electricity. 
While the agency may use more site energy, it reduces its electricity 
purchases and the use of associated fuels at the power plant, thereby 
decreasing total energy use. According to DOE, these credits are 
expected to continue as a necessary adjustment for the site-delivered 
Btu-per-gross-square-foot performance measure. 

* Greenhouse gas emissions. Reduce greenhouse gas emissions by reducing 
energy intensity by 6 percent by 2007, from a 2003 baseline. After 
2007, agencies are to reduce greenhouse gas emissions by reducing 
energy intensity by 3 percent annually, or a total of 30 percent by the 
end of fiscal year 2015, relative to a 2003 baseline. 

* Renewable energy. Of the total amount of electricity consumed, at 
least 3 percent must be from a renewable energy source, with at least 
half of that amount from a renewable energy source put into service 
after January 1, 1999. This goal is in place through 2009. After 2009, 
the percentage of electricity from a renewable energy source increases 
incrementally, but at least half of the amount must still be from 
renewable energy sources put into service after January 1, 
1999.[Footnote 8] Under EPAct 2005, agencies also get a 100 percent 
bonus for renewable electric energy generated on federal or Indian 
land. Under E.O. 13423, this energy must be defined as "new" to qualify 
for the bonus. 

DOE, the Office of the Federal Environmental Executive (OFEE), and the 
Office of Management and Budget (OMB) play a role in ensuring that 
agencies comply with the goals. DOE is responsible primarily for 
coordinating the implementation of the energy efficiency and renewable 
energy goals for agencies set forth in EPAct 2005, while OFEE is 
responsible primarily for overseeing the implementation of E.O. 13423. 
In practice, OFEE has delegated much of its responsibility for 
achieving federal energy goals to DOE. OMB is responsible for, among 
other things, issuing semiannual scorecards that track agencies' energy 
performance for a number of indicators. 

DOE develops and issues guidance on how to meet the energy goals. It 
also chairs the Interagency Energy Management Task Force, a group of 
agency headquarters-level energy managers who, among other things, 
address energy issues affecting federal buildings and operations and 
comment on guidance. DOE also reports annually to Congress on agencies' 
energy use and progress toward meeting energy goals. Not all agencies 
report every year, and the agencies reporting may vary from year to 
year; however, the majority of federal agencies report each year. In 
some cases, when control of a building is delegated from the General 
Services Administration (GSA) to an agency, the agency will then be 
required to report to DOE, which may influence the number of agencies 
included in the annual report. 

To achieve the energy goals, agencies may take a range of actions, from 
switching to more energy-efficient lighting and encouraging staff to 
conserve energy, to ensuring that all new building construction meets 
higher energy efficiency standards. Agencies pay for these improvements 
in several ways; for example, they may use upfront funding to pay for 
the improvements outright or they may rely on alternative financing 
mechanisms, such as contracts with private companies that pay for 
energy improvements to begin with and then receive compensation from 
the agencies over time from the monetary savings they realize from 
these projects. 

In this context, you asked us to determine the extent to which (1) 
federal agencies met energy efficiency, greenhouse gas emission, and 
renewable energy goals in fiscal year 2007; (2) federal agencies have 
made progress in each of these areas in the recent past; and (3) 
selected agencies are poised to meet energy goals into the future. We 
plan to report in fall 2008 on energy efforts related to the federal 
government's vehicle fleets. 

To determine the extent to which agencies met energy efficiency, 
greenhouse gas, and renewable energy goals, we analyzed data on 
agencies' performance, as reported in DOE's annual reports to Congress 
for fiscal year 2005, and draft data from fiscal years 2006 and 2007. 
We determined these data to be sufficiently reliable for our purpose, 
which was to convey what the agencies reported to DOE about the status 
of meeting the energy goals. To assess the agencies' progress in each 
of these areas in recent years, we reviewed energy efficiency, 
greenhouse gas, and renewable energy goals in current and previous 
statutes and executive orders. We also met with officials from DOE, 
OFEE, and OMB to gain their perspective on the goals. To determine the 
extent to which the agencies are poised to meet future energy goals, we 
selected six agencies on the basis of several factors, such as the 
agencies' combined energy consumption as a percentage of the federal 
government's consumption (nearly 94 percent in fiscal year 2005). 
Because these six agencies accounted for nearly 94 percent of the 
energy consumed in standard buildings in fiscal year 2005, our findings 
for these agencies may have great implications for the federal 
government as a whole. The selected agencies are the Departments of 
Defense (DOD)--Air Force, Army, and the Department of Navy--Energy, and 
Veterans Affairs (VA); GSA; the National Aeronautics and Space 
Administration (NASA); and the U.S. Postal Service (USPS). We obtained 
documentation and met with headquarters officials from these six 
agencies. We visited a minimum of two sites per agency to determine 
their efforts toward meeting energy goals at the local level. We also 
met with officials from the Alliance to Save Energy (ASE), a nonprofit 
organization recognized for its work on energy issues. Appendix I 
contains a more detailed discussion of our scope and methodology. We 
conducted this performance audit from May 2007 through September 2008 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives. 

Results in Brief: 

Most of the 22 agencies reporting to DOE for fiscal year 2007 met their 
energy-related goals, according to draft data supplied by the agencies. 
All but 1 agency met the energy efficiency goal of a 6 percent 
reduction in energy intensity from a 2003 baseline. Because the 
greenhouse gas emission direction is tied to the energy efficiency 
goal, all but 1 agency also met the greenhouse gas emissions goal of a 
6 percent reduction in energy intensity from a 2003 baseline. Three 
agencies used renewable energy purchase or source energy credits to 
meet the goals and would not have met the goals through reductions in 
energy intensity alone. Seventeen of the 22 agencies met the renewable 
energy goal of having 3 percent of their electricity consumption from 
renewable resources, with at least half of this amount from renewable 
sources placed into service after January 1, 1999. 

Assessing the extent to which agencies have made progress over time 
toward the goals of increasing energy efficiency, reducing greenhouse 
gas emissions, or increasing the use of renewable energy is problematic 
due to key changes in the energy goals and how the goals are measured-
-as specified in statute and executive order. For example, before 2006, 
buildings subject to the energy efficiency goal were divided into two 
categories--one for standard buildings measured against a 1985 baseline 
and one for industrial and laboratory buildings measured against a 1990 
baseline--but the goal for 2006 onward is based only on one building 
category measured against a 2003 baseline. As a result, comparing 
agency performance in meeting the goal before and after 2006 is 
problematic and does not meaningfully describe energy efficiency 
progress toward the goal over time. In the case of greenhouse gas 
emissions, measurement is even more complex. The 2007 executive order 
not only changed the baseline year but also fundamentally changed what 
is being measured. Before 2007, the greenhouse gas emissions goal, set 
in 1999 by executive order, was to reduce the amount of emissions, 
which is significantly different from the energy-intensity-based goal 
for 2007 onward. In fact, the goal the administration established in 
the executive order may not accurately reflect progress toward the goal 
of reducing greenhouse gas emissions. That is, energy intensity is not 
always a good proxy for emissions depending on, among other things, the 
energy sources used. For example, if an agency's square footage and 
energy consumption remain constant while the agency switches to sources 
with greater greenhouse gas emissions, its energy intensity remains 
constant while the greenhouse gas emissions increase. In fact, we found 
instances in which agencies' energy intensity decreased while their 
greenhouse gas emissions increased. While an energy-intensity-based 
goal, such as the current goal under the 2007 executive order, does not 
always indicate progress toward the goal of reducing greenhouse gas 
emissions, there is no consensus on a best measure at present; however, 
there are alternative measures that may better track agencies' 
greenhouse gas emissions than the current measure based on energy 
intensity. 

The prospects for meeting energy goals into the future for the six 
agencies we examined depend largely on addressing four key challenges: 
(1) lack of key elements in long-term plans that would help provide 
agency direction, (2) budget constraints for energy projects, (3) 
measurement and data reliability issues, and (4) lack of expertise and 
dedicated energy management staff. However, agencies are planning to 
meet energy goals by undertaking several activities to address these 
four challenges. 

* Long-term plans lack key elements. Long-term plans can help clarify 
organizational priorities and unify agency staff in the pursuit of 
shared goals. As previous GAO work has shown, such plans should, among 
other things, outline agency strategies that are linked to goals and 
provide a framework for aligning agency activities, processes, and 
resources to attain the goals of the plan; identify the resources 
needed; and provide for reliable performance data needed to set goals, 
evaluate results, and improve performance.[Footnote 9] The long-term 
plans for the six agencies we reviewed lack many of these key elements. 
Furthermore, four of the six agencies have not updated their plans to 
reflect the goals set out by E.O. 13423. DOE has drafted guidance for 
agencies on developing long-term plans that addresses most of the key 
elements we identified. This guidance will be published in final form 
upon completion of DOE internal review and reconciliation with new 
planning requirements in the Energy Independence and Security Act of 
2007 (EISA 2007). In the absence of long-term plans, agency officials 
reported using several tools to meet energy goals, including short-term 
plans for energy improvements, as well as energy audits to identify and 
plan future energy projects. However, these tools do not focus on 
efforts to meet the energy goals through fiscal year 2015 and may not 
ensure that agencies will meet these goals. 

* Constrained budgets limit energy projects. According to agency 
officials, meeting long-term energy goals will require major initial 
capital investment, but such investments must compete with other budget 
priorities. To overcome budget constraints, and, partly in response to 
administration guidance, officials are increasingly turning to 
alternative financing mechanisms that primarily rely on third parties 
to fund projects, with the promise that the agency will repay the third 
parties from energy savings. This approach offers benefits and presents 
challenges. For example, according to DOD officials, the department 
needs these mechanisms to achieve long-term energy goals, but these 
mechanisms can take a long time to implement and require contracting 
and oversight expertise not always available on-site. In addition, as 
previous GAO work has shown, agencies entering into these contracts 
could not always verify whether money saved from using less energy was 
greater than projected costs and may yield lower savings than if 
timely, full, and upfront appropriations had been used.[Footnote 10] 
Some agencies are undertaking initiatives, such as centralizing the 
contracting process for energy projects, to overcome challenges 
associated with alternative financing. 

* Measurement and data reliability issues. Reliable data are essential 
to making decisions. Currently, however, some agencies estimate energy 
use from monthly bills, handwritten ledgers, or other sources that may 
not be reliable. To address this challenge, agencies have and are 
pursuing some mechanisms to improve data reliability. For example, all 
of the six agencies we met with plan to install advanced electrical 
meters on buildings by 2012, as required by EPAct 2005. 

* Some sites lack expertise and dedicated energy management staff. 
Complex energy projects may require high levels of expertise and 
dedicated energy management staff. However, according to officials at 
several of the sites we visited, they do not have a full-time energy 
manager and lack staff with expertise in negotiating and overseeing 
alternative financing mechanisms, both of which hinder their efforts to 
meet energy goals. In addition, several sites have had difficulty 
retaining qualified and experienced personnel to manage energy 
efficiency projects. To make up for this loss of expertise, agency 
officials reported taking steps such as having staff attend training 
courses to learn about a variety of energy topics, including 
alternative financing contracts. 

Because the change to an energy-intensity-based metric does not always 
accurately reflect greenhouse gas emissions, we are recommending that 
the Secretary of Energy, in conjunction with the Federal Environmental 
Executive and the Director of the Office of Management and Budget, re- 
evaluate the current measure for greenhouse gas emissions and establish 
one that more accurately reflects agencies' performance in reducing 
these emissions. We also are recommending that the Secretary of Energy 
finalize and issue guidance for agencies' use in developing long-term 
plans that contains key elements for meeting current and future energy 
goals. 

In commenting on a draft of this report, NASA and USPS generally agreed 
with our findings, conclusions, and recommendations and provided 
written comments included as appendixes II and III, respectively. GSA 
responded by e-mail on September 8, 2008, stating that it concurred 
with our report. VA neither agreed nor disagreed with our report and 
provided written comments included as appendix IV. The Council on 
Environmental Quality, DOD, DOE, and OMB did not provide any comments

comments, we incorporated those as appropriate. 

Background: 

From fiscal year 2000 to fiscal year 2007, agencies were to meet the 
energy goals established by two executive orders and a statute as shown 
in figure 2.

Fiscal Years 2000-2007:

goals, fiscal years 2000-2007.

meet for a particular fiscal year. The dotted lines represent goals 
that are currently still in effect. 

[End of figure] 

Using energy data that agencies submit, DOE reports to Congress on 
agencies' performance toward meeting these energy goals. According to 
DOE, for fiscal year 2007, the buildings subject to these energy goals 
consumed approximately one-third of the energy consumed by the federal 
government as a whole.[Footnote 11] Federal buildings obtain this 
energy from a number of different energy types, as shown in figure 3.

Year 2007:

type, fiscal year 2007.

[End of figure] 

According to 2007 national data from DOE's Energy Information 
Administration, electricity generation consists of coal (49 percent), 
natural gas (21 percent), nuclear electric power (19 percent), 
hydroelectric power (6 percent), and other (5 percent). 

Carbon dioxide and certain other gases trap some of the sun's heat in 
the earth's atmosphere and prevent it from returning to space. The 
trapped heat warms the earth's climate, much like the process that 
occurs in a greenhouse. Hence, the gases that cause this effect are 
often referred to as greenhouse gases. Fuel types vary in the amount of 
greenhouse gases that they emit. For example, the burning of coal and 
oil emits greater quantities of greenhouse gases during energy use than 
other fossil fuels, such as natural gas. Renewable energy is produced 
from sources that cannot be depleted and, unlike fossil fuels, most 
renewable sources do not directly emit greenhouse gases. 

DOE Reports That Most Federal Agencies Met Fiscal Year 2007 Energy 
Goals: 

According to draft data agencies provide to DOE, most of the 22 federal 
agencies reporting in fiscal year 2007 met the energy efficiency, 
greenhouse gas emission, and renewable energy goals. Some agencies used 
credits to meet the goals and would not have met the goals through 
reductions in energy intensity alone. Figure 4 shows the energy 
consumed, measured at the site where it is consumed rather than the 
source of the energy, in buildings that are subject to the energy 
goals, for 10 agencies with the highest energy consumption, in addition 
to the other 12 agencies reporting to DOE in fiscal year 2007. The 
other 12 agencies consumed a combined total of only about 4 percent of 
total site-delivered energy.

Energy efficiency. As figure 5 shows, all but one agency met the 2007 
energy efficiency goal laid out in E.O. 13423, which calls for a 6 
percent reduction in energy intensity from a 2003 baseline. Among the 
agencies held to the goal, only the Railroad Retirement Board missed 
it, reducing energy intensity by 5.8 percent from its 2003 baseline. 
The Environmental Protection Agency (EPA) reduced energy intensity by 
63.8 percent from a 2003 baseline, which was the largest reduction 
among the agencies. As a whole, the 22 agencies met the energy 
efficiency goal, with agencies cumulatively reducing energy intensity 
by 11 percent from 2003 levels.

Use of credits for the purchase of renewable energy and source energy 
was common among agencies in 2007. USPS was the only agency that did 
not use any credits. Of the 21 agencies that used credits, 3 that met 
the energy efficiency goal with the credits would not have met the goal 
without them. EPA achieved the greatest percentage of its energy 
intensity reduction using credits--81.2 percent of its overall 
reduction in energy intensity came from the use of credits--
representing about 5 percent of the total credits the federal 
government used. In contrast, about a third of DOD's reduction in 
energy intensity came from credits, but this reduction accounted for 
over half of all the credits the federal government used because DOD is 
overwhelmingly the largest consumer of energy in the government. Almost 
one-third of the total reduction in energy intensity reported by 
agencies is attributable to the use of credits. 

Most agencies--21 of 22--used renewable energy purchase credits in 
fiscal year 2007. Five agencies also used source energy credits. For 
all agencies, renewable energy purchase credits accounted for about two-
thirds of all credits used. Both types of credits were established 
under E.O. 13123. Source credits were aimed at helping the federal 
government reduce total energy use at the source of generation. 
According to DOE, renewable energy purchase credits were established to 
support the renewable energy industry. Although the credits were 
established to support federal energy policies, they do not reflect 
actual decreases in energy intensity. 

Greenhouse gas emissions. The same 21 of 22 agencies met the 2007 
greenhouse gas emissions goal under E.O. 13423, which holds agencies to 
the same standard as the energy efficiency goal--a 6 percent reduction 
in energy intensity from a 2003 baseline. The same renewable energy 
purchase and source energy credits that count toward the energy 
efficiency goal also count toward the greenhouse gas emissions goal. 

Renewable energy. Seventeen of the 22 agencies met the fiscal year 2007 
renewable energy goal, as figure 6 shows. This goal requires that at 
least 3 percent of total electric energy consumption come from 
renewable energy sources, with at least half of the required renewable 
energy an agency consumes coming from resources put into service after 
January 1, 1999. The departments of Health and Human Services, Justice, 
and State; the Social Security Administration; and USPS missed the 
goal.[Footnote 12] EPA achieved the greatest percentage of total 
electric consumption from renewable sources, with 153.5 percent. EPA 
was able to count more than 100 percent of its electricity consumption 
as renewable because it bought renewable energy certificates that 
exceeded the electricity it used, and because it received a small bonus 
for renewable energy generated on federal or Indian land.[Footnote 13] 
As a whole, the federal government met the renewable energy goal, with 
4.9 percent of its electricity use coming from renewable sources and at 
least half of this energy coming from newer renewable sources; only 
about 3 percent of the renewable energy total is attributable to 
bonuses.

Assessing Progress Toward the Goals Over Time Is Problematic Due to Key 
Changes in the Goals and How Performance Is Measured: 

Determining the extent to which agencies have made progress toward the 
goals over time is problematic due to key changes in the goals--as 
specified in statute and executive order--and how performance is 
measured. Performance can be compared across years when the way a goal 
is measured remains unchanged. After substantial change, however, there 
is no consistent measure against which to compare long-term progress 
toward the goals. 

Energy efficiency. Key changes in the energy efficiency goal since 2005 
illustrate the difficulty in making comparisons. As figure 7 shows, 
EPAct 2005 made key changes in both building categories and baseline 
years, and also changed the percentage reduction and the year by which 
agencies should have reduced energy intensity by that percentage. 

Figure 7: Changes in How the Energy Efficiency Goal Is Measured: 

This figure is a table with an illustration showing changes in how the 
energy efficiency goal is measured.

data for the baseline year. 

[End of figure] 

These key changes make it problematic to compare agency performance 
against the goal before and after EPAct 2005 took effect. Although all 
but 1 of 22 agencies met the single energy efficiency goal in 2007 for 
buildings subject to the goal, according to draft DOE data, this 
performance cannot be directly compared with performance in 2005. In 
that year, only 8 of 17 agencies met the goal for standard buildings 
and 8 of 12 agencies met the goal for industrial and laboratory 
buildings.[Footnote 14] Difficulty in comparing agency performance 
against the goal mainly resulted because of the key changes in building 
categories and baselines. The change from two building categories-- 
standard and industrial and laboratory--to only one category changed 
the total square footage included in the energy intensity 
calculation.[Footnote 15] 

Data on NASA's performance against the energy efficiency goal in 2005 
and 2007 show the difficulty in gauging progress after a key change to 
a goal. In 2005, the agency met the standard building goal by reducing 
energy intensity for those buildings by 30.4 percent against a 1985 
baseline, exceeding the goal of 30 percent. It missed the industrial 
and laboratory building goal, reducing energy intensity for those 
buildings by 16.1 percent against a 1990 baseline, short of the goal of 
20 percent. In 2007, NASA exceeded the goal for all buildings subject 
to the goal by reducing energy intensity by 17.6 percent against a 2003 
baseline, well over the goal of a 6 percent reduction. However, because 
of changes in the baseline year and building categories, NASA's 
performance against the goal in 2007 cannot be directly compared with 
its performance in 2005 or earlier. 

While we focused on how changes to measurement of the energy efficiency 
goal make assessing progress toward meeting the goal problematic, DOE 
also maintains actual energy intensity data for reporting agencies 
dating back to 1985. According to the data, agencies decreased energy 
intensity in all their buildings from 1985 to 2007 by approximately 
14.3 percent. However, these data do not reflect the evolution of the 
energy efficiency goal during that period. For example, buildings that 
are excluded under the executive orders and EPAct 2005 are included in 
these totals. 

Greenhouse gas emissions. Similar comparative difficulties show up in 
examining progress toward the goal of reducing greenhouse gas 
emissions. Before 2007, under E.O. 13123, the goal called for reducing 
the amount of emissions by 30 percent by 2010 compared to a 1990 
baseline. E.O. 13423 significantly changed how the federal government 
measures progress toward this goal. Now, the greenhouse gas emissions 
direction is measured using energy intensity against a 2003 baseline. 
Figure 8 shows the details of these changes. 

Figure 8: Changes in How the Greenhouse Gas Emissions Goal Is Measured: 

This figure is a table with illustration showing changes in how the 
greenhouse gas emissions goal is measured.

[A] Progress is determined by comparing the most recent data with the 
data for the baseline year. 

[End of figure] 

Performance against the greenhouse gas emissions goal may be compared 
from 2000 to 2006, when E.O. 13123 remained in place and the goal was 
measured in the same way. However, the key change in E.O. 13423 from 
greenhouse gas emissions to energy intensity means that it is 
problematic to compare agency performance in 2007--when all but 1 
agency met the greenhouse gas emissions goal--with performance in 2005-
-when only 7 of 21 agencies were on track to meet the goal. For 
example, VA actually increased its greenhouse gas emissions in 2005 by 
20.3 percent from its 1990 level, and was far from meeting the 
greenhouse gas emissions goal of a 30 percent reduction by 2010. In 
2007, however, it met the emissions goal because it exceeded the energy 
efficiency goal. 

E.O. 13423 states that agencies are to reduce greenhouse gas emissions 
by reducing energy intensity. However, a reduction in energy intensity 
does not track directly with lower greenhouse gas emissions for two 
reasons. First, if an agency's energy consumption increases but square 
footage increases at a greater rate, then energy intensity is reduced 
while greenhouse gas emissions will increase, assuming all else remains 
unchanged. Second, the level of greenhouse gas emissions depends on the 
type of fuel used to generate energy. However, energy intensity does 
not account for different fuel types. Rates of carbon intensity vary by 
energy type per Btu delivered, especially for electricity, depending on 
whether it is generated from a fossil fuel, nuclear, or renewable 
source. Consequently, if an agency's square footage and energy 
consumption remain constant but the agency switches to sources that 
emit more greenhouse gases, such as switching from natural gas to coal, 
its energy intensity remains constant while greenhouse gas emissions 
increase. Conversely, switching from fossil-generated electricity to 
renewable electricity virtually eliminates greenhouse gas emissions. 
Although E.O. 13423 changed the measure for greenhouse gas emissions, 
DOE still estimates and reports greenhouse gas emissions by considering 
the sources used to produce energy and agency energy consumption. 

The imperfect relationship between energy intensity and greenhouse gas 
emissions shows up in DOE data: we found cases in which energy 
intensity decreased over time, but greenhouse gas emissions increased. 
According to draft DOE data, at the Department of Commerce, for 
example, from 2003 to 2007, energy intensity decreased by 22.3 percent 
while greenhouse gas emissions increased by 2.4 percent. Similarly, the 
National Archives and Records Administration's energy intensity 
decreased by 18.7 percent over the period but greenhouse gas emissions 
increased by 21.5 percent. Although the National Archives and Records 
Administration's and the Department of Commerce's greenhouse gas 
emissions increased while energy intensity decreased, mostly 
attributable to increases in square footage of their building 
inventories, for the government as a whole greenhouse gas emissions 
decreased by 9.4 percent from 2003 to 2007 while energy intensity 
decreased by 11 percent. 

It is not clear why the administration changed from an absolute 
emissions measure to one tied to energy intensity. When we asked about 
using energy intensity as a proxy for greenhouse gases, an official 
with OFEE told us that it is the administration's policy not to tie 
greenhouse gas emissions to a specific measure. Rather, it is the 
administration's policy to encourage agencies to voluntarily partner 
with other groups to reduce emissions, and the administration believes 
emissions will decline without a quantifiable goal. 

Although energy intensity is an imperfect measure of greenhouse gas 
emissions, there is no scientific consensus on the best measure. Some 
organizations, such as the Energy Information Administration, a 
statistical agency of DOE which provides data, forecasts, and analyses, 
and the World Resources Institute,[Footnote 16] have used or proposed 
several alternatives for measuring greenhouse gas emissions. Such 
measures include reporting total emissions, as was the case for the 
previous greenhouse gas emissions goal under E.O. 13123, and using 
greenhouse gas intensity measures. Some greenhouse gas measures, like 
the current energy intensity measure based on square footage, attempt 
to account for expanding or shrinking production or mission. Other 
proposed measures have included calculating greenhouse gas intensity by 
dividing total greenhouse gas emissions by building square footage or 
by units of performance or output, such as million dollars of gross 
domestic product or economic output, kilowatt hour, customer, or dollar 
of revenue. DOE, in its annual reports to Congress, estimates emissions 
from energy use in buildings that are subject to the goal, and presents 
annual emissions in metric tons of carbon dioxide equivalent, and in 
terms of metric tons of carbon dioxide equivalent per gross square 
foot. 

None of the measures is perfect. For example, one agency official noted 
that an absolute emissions goal--as was used to measure emissions prior 
to the current measure--does not account for the fact that an agency 
may change its energy consumption or square footage to support its 
expanded or contracted work resulting from a change in mission. 
However, this absolute emissions measure allowed agencies to more 
easily track progress in reducing their total emissions. Imperfect 
metrics also are an issue at the international level. For example, one 
measure currently used by the Energy Information Administration is 
"emissions intensity," measured in emissions in a given year divided by 
the economic output for that year, which accounts for changes in 
national output. As past GAO work has shown, a decrease in this 
intensity-based measure may result in increased greenhouse gas 
emissions.[Footnote 17] 

Renewable energy. Key changes in the renewable energy goal since 2005 
also make comparisons over time problematic. While both EPAct 2005 and 
E.O. 13423 specified different ages of renewable sources counted toward 
meeting the energy goal, E.O. 13423 did not change the percentage 
required or time frames required of the agencies, as figure 9 shows. 
Further, forms of nonelectric renewable energy such as solar thermal, 
geothermal, and biomass gas do not count toward the EPAct 2005 goal. 
E.O. 13123 did count these forms of renewable energy toward its goal.

Performance against the renewable energy goal may be compared from 2000 
to 2006, when the goal remained unchanged. But the change in the age 
requirement for renewable sources makes it problematic to compare 
performance in 2007 with previous years. For example, although 17 of 22 
agencies met the goal in 2007 and 10 of 20 met the goal in 2005, 
comparing performance in these 2 years is problematic because, with the 
2007 goal, half of renewable energy came from sources in service from 
1999 or later, but there is no source age specification for the other 
half. However, with the 2005 goal, all of the renewable energy came 
from energy sources in service in 1990 or later. Also, thermal 
renewable energy used in 2005 was not eligible to be counted toward the 
2007 goal. 

Data on VA's performance illustrate the difficulty in making 
comparisons when the age requirement for renewable energy sources has 
changed. In 2005, VA exceeded the goal of having 2.5 percent of its 
electricity consumption from renewable sources put into service since 
January 1, 1990, with 2.9 percent of its electricity consumption from 
these sources. In 2007, VA exceeded the new 3 percent goal, with 3.4 
percent of its electricity from renewable sources, 1.8 percent from new 
sources put into service since 1999, and 1.6 percent from older 
eligible sources. Although VA increased its total renewable energy use, 
it is not clear whether its use from sources put into service since 
January 1, 1990, has increased or decreased, thereby making comparisons 
across the goals problematic. 

Agencies' Prospects for Meeting Energy Goals in the Future Depend on 
Addressing Four Challenges: 

The prospects for meeting the energy goals in the future for the 
agencies we reviewed depend largely on overcoming four key 
challenges.[Footnote 18] First, long-term plans can help clarify 
priorities and help agency staff pursue shared goals, but the six 
agencies we reviewed had long-term plans for achieving energy goals 
that lacked several of the key elements that we have identified in our 
prior work that make such plans effective. Second, achieving long-term 
energy goals will require major initial capital investments, but it is 
difficult for such investments to compete with other budget priorities. 
To address this problem, federal officials increasingly rely on 
alternative financing mechanisms; while these mechanisms provide 
benefits, they also present challenges. Third, agencies we reviewed 
face challenges in obtaining sufficiently reliable data on energy 
consumption; however, most agencies have tools for ensuring data are 
reliable and have plans to more accurately capture energy data. 
Finally, sites may lack staff dedicated to energy management, and also 
may find it difficult to retain staff with sufficient energy 
expertise;[Footnote 19] lack of expertise could make it difficult to 
undertake alternative financing projects. Federal officials are 
participating in energy-related training courses and undertaking 
initiatives to hire, support, and reward energy management personnel. 

Agencies' Planning Documents We Reviewed Lack Key Elements Needed to 
Guide Achievement of Long-term Energy Goals: 

Long-term plans can help clarify organizational priorities and unify 
agency staff in the pursuit of shared goals. These plans also must be 
updated to reflect changing circumstances, and according to our 
previous work, plans should include a number of key elements, including 
(1) approaches or strategies for achieving long-term goals; (2) 
strategies that are linked to goals and provide a framework for 
aligning agency activities, processes, and resources to attain the 
goals of the plan; (3) identification of the resources needed; (4) 
strategies that properly reflect and address external factors; and (5) 
reliable performance data needed to set goals, evaluate results, and 
improve performance.[Footnote 20] Long-term plans with these elements 
help an agency define what it seeks to accomplish, identify the 
strategies it will use to achieve results, and determine how well it 
succeeds in achieving results and objectives. 

While none of the six agencies we reviewed could provide us with what 
we considered to be a comprehensive, long-term energy plan, agency 
officials did provide numerous planning documents, including budget 
documents, strategies for improving energy efficiency, energy program 
guidance, and agencywide energy policies for sites. For the purposes of 
our review, we considered any of these planning documents, if they 
discussed actions to be taken beyond 12 months, as long-term energy 
plans. However, we determined that the long-term energy plans for one 
or more of the six agencies lacked some of the following key elements 
for effective long-term energy planning: 

* approaches or strategies for achieving long-term energy goals; 

* strategies that linked energy goals and provide a framework for 
aligning agency activities, processes, and resources to attain the 
goals of the plan; 

* identification of the required resources needed to achieve long-term 
energy goals; 

* strategies that properly reflect and address external factors; and: 

* provisions for obtaining reliable performance data needed to set 
goals, evaluate results, and improve performance. 

Moreover, four of the six agencies' long-term plans were not updated to 
reflect E.O. 13423, although two of these agencies noted that they are 
in the process of updating these plans. In addition, in April 2008, the 
USPS Inspector General's office reported on the value of long-term 
energy plans and determined that USPS does not have a long-term energy 
management plan, and that without one USPS cannot effectively maximize 
its energy conservation efforts. The USPS Inspector General recommended 
the Postal Service develop and publish a National Energy Management 
Plan. This plan is expected to be published in early fiscal year 2009. 

While long-term planning generally is recognized as an important tool 
in achieving goals, federal agencies have not been required to have 
long-term plans for energy goals. To close this gap, DOE is drafting 
guidance for agencies to follow as they develop multiyear plans and 
long-term strategies for assessing the level of investment necessary to 
meet energy goals, their progress in meeting these goals, and the 
likelihood that they will achieve these goals by 2015. Our preliminary 
review of the draft guidance found that it appears to address all of 
the key elements we identified. According to DOE officials, this 
guidance will be published in final form upon completion of DOE 
internal review, as well as analysis and reconciliation with new 
planning requirements in the EISA 2007. 

In the interim, the six agencies are addressing long-term energy 
planning deficiencies in two ways. First, in recent years officials in 
agencies' headquarters have used short-term plans to achieve energy 
goals in the near term. All of the agencies that reported to DOE were 
required to provide annual plans under E.O. 13123 that included 
guidance on energy requirements and strategies each agency is taking 
over the next year to meet these requirements. However, E.O. 13423 does 
not require agencies to provide these annual plans. Agencies also used 
other planning tools to achieve energy goals in the short term. For 
example, GSA sets annual regional targets and requires each region to 
submit plans on how it will achieve these targets.[Footnote 21] 
Agencies also submit budgetary documents requesting funds for specific 
energy projects. 

Officials at the sites we visited had used a number of short-term plans 
to achieve energy improvements, but did not know how they would meet 
long-term energy goals. In several cases, these officials stated, they 
are planning to meet future energy goals by completing individual 
projects in the near term. For example, officials at one GSA site 
reported that they typically plan energy projects on a year-to-year 
basis, depending on the available funds, and did not have a long-term 
energy plan. At one USPS site, officials said they have not yet 
documented a comprehensive, long-term plan highlighting the steps they 
have taken or intend to take to ensure they reach energy goals. In 
addition, officials at a DOE site stated that it is difficult to plan a 
long-term approach for achieving energy goals because the site's 
mission is constantly evolving. Moreover, most military installations 
we visited did not have a long-term plan to achieve energy savings into 
the future and were instead developing individual projects to improve 
the energy efficiency in existing structures. 

Second, agencies are using energy audits as a way to identify potential 
energy savings and meet long-term goals. In the past, we have reported 
that energy audits are a key strategy for identifying and evaluating 
future energy projects,[Footnote 22] and officials at all the agencies 
we spoke with reported undertaking energy audits as a tool to identify 
and plan future energy projects. 

Since 1998, NASA has conducted reviews at each of its centers every 3 
years to assess their energy and water management programs. The review 
requires center staff to participate in a self-assessment by responding 
to a set list of questions, confer with headquarters officials during a 
week-long site visit, and discuss review findings including 
recommendations. 

USPS currently is conducting energy audits for 60 million square feet 
of its 310 million square feet of facility space, which will identify 
close to 2 trillion Btus of potential savings upon completion. 

In 2007, VA conducted energy and water audits covering six regions and 
a total of 64 sites, or a total of 20 percent of its sites. During 
2008, VA officials expect to audit 30 percent of its sites, which 
include 116 sites in seven regions. 

Energy audits are part of the Air Force's energy program and were 
undertaken to identify additional energy-related projects, and act as 
measures of how to reduce energy consumption. 

While short-term planning and energy audits help guide agencies' 
efforts toward meeting their goals in the near term, they do not 
address how the agencies will meet the goals through 2015. 

Constrained Budgets Limit Agencies' Ability to Undertake Energy 
Projects, and Agencies Are Turning to Alternative Financing: 

Meeting long-term energy goals will require major initial capital 
investment. According to DOE, to meet the energy goals under E.O. 
13423, the federal government would have to invest approximately $1.1 
billion annually (beginning in fiscal year 2008, based on fiscal year 
2007 performance) through 2015 on energy-related projects. In addition, 
in June 2007, ASE reported that meeting federal energy goals will 
require an investment of approximately $11 billion from 2009 through 
2015, or $1.5 billion annually.[Footnote 23] 

Paying for this investment up front with appropriated funds may be 
difficult for agencies because energy projects compete with other 
budget priorities. As figure 10 shows, from fiscal years 2000 through 
2007, upfront funding ranged from approximately $121 million to $335 
million annually--well below the $1.1 billion level of investment 
needed annually to meet future energy goals, according to DOE's 
estimate. Furthermore, according to draft DOE data for fiscal year 
2007, federal agencies will face an estimated $5.3 billion gap in 
appropriated funding for energy investment from fiscal year 2008 
through 2015.

[End of figure] 

Officials from all six agencies we reviewed cited budget constraints as 
a challenge to meeting future energy goals. For example, only 4 of the 
10 military installations we visited have received upfront funding from 
DOD's Energy Conservation Investment Program since 2003.[Footnote 24] 
Furthermore, several DOD installation officials told us that they no 
longer request funding for energy improvements because they do not 
believe upfront funding will be made available. In our previous work we 
similarly noted that agency officials had stopped requesting such 
funding. We also noted that paying for energy efficiency improvements 
with upfront funding is generally the most cost-effective means of 
acquiring them.[Footnote 25] 

Because the total amount of upfront funding is limited, federal 
officials increasingly rely on alternative financing mechanisms--such 
as contracts with private companies that initially pay for energy 
improvements and then receive compensation from the agencies over time 
from the monetary savings they realize from these projects-- to meet 
energy goals. Seven of the 11 civilian sites and 9 of the 10 military 
installations we visited have used, are currently using, or are 
planning to use alternative financing to implement energy projects. 
Furthermore, in an August 2007 memo, the White House Council on 
Environmental Quality directed agency heads to enter into energy 
savings performance contracts (ESPC) and utility energy savings 
contracts (UESC) for at least 10 percent of annual energy costs to 
accomplish energy-related goals.[Footnote 26] It further directed them 
to report on progress toward finding and developing alternatively 
financed projects.[Footnote 27] Figure 11 shows the total amount of 
funding agencies received from upfront funding and alternative 
financing for UESCs and for ESPCs. As discussed earlier, most agencies 
met their fiscal year 2007 goals. However, for 2008 onward, if funding 
stays at the current level, there is an apparent gap between the amount 
received and the amount estimated to meet energy goals.

Note: This figure shows the primary sources of funding. Agencies also 
may use other funding sources, such as operating and maintenance 
funding. ESPC authority lapsed on October 1, 2003, and was reinstated 
in October 2004. 

[End of figure] 

According to agency officials, alternative financing mechanisms offer 
benefits but also present challenges. In terms of benefits, these 
mechanisms can be used to complete energy projects and meet federal 
energy reduction goals when upfront funding is not available. For 
example, DOD officials stated that alternative financing mechanisms are 
necessary for DOD to meet future energy goals and, in March 2008 
testimony before the Subcommittee on Readiness, House Committee on 
Armed Services, the Deputy Under Secretary of Defense for Installations 
and Environment stated that ESPCs typically account for more than half 
of all site energy savings.[Footnote 28] Furthermore, according to DOD, 
the agency fell short of meeting past energy efficiency goals owing to 
a lapse in ESPC authority from October 2003 to October 2004. In 
addition, DOE officials noted that alternative financing mechanisms 
provide large energy savings per dollar spent and estimated that ESPC 
project savings generally exceed guaranteed energy savings by about 10 
percent. In 2005, we reported that agencies cited other benefits from 
alternatively financed projects, such as improved reliability of the 
newer equipment over the aging equipment it replaced, environmental 
improvements, and additional energy and financial savings once the 
contracts have been paid for.[Footnote 29] 

Agency officials also noted several challenges associated with such 
projects. For example, VA officials noted that development, execution, 
and ongoing administration of alternative financing contracts add 
overhead costs that increase the total cost of the contract. 
Furthermore, according to DOD officials, overseeing these contracts 
requires a level of expertise not always available at individual 
installations, and such contracts often take a long time to implement. 
In addition, officials at a number of civilian sites commented that 
developing alternatively financed projects requires a steep learning 
curve and the process for developing a contract can be time consuming. 
Finally, officials at a few agencies noted that in using these 
alternative financing mechanisms, it is difficult to measure and verify 
energy savings and to manage contracts with lengthy payback periods. 
Our June 2005 report also showed that agencies entering into these 
alternative finance contracts could not always verify whether energy 
savings were greater than project costs and may yield lower dollar 
savings than if timely, full, and upfront appropriations had been used. 
In addition, in our December 2004 report, DOD officials commented that 
the costs of using such contracts was 25 percent to 35 percent above 
what costs would have been in using upfront funds for certain energy 
projects. 

Some agencies are undertaking initiatives to overcome the challenges 
associated with alternative financing. 

* VA has created a central contracting center for energy projects, 
including alternatively financed projects. VA officials believe the 
center will offer a number of benefits, including the development of 
alternative financing expertise, increased accountability, greater 
agencywide awareness of these financing mechanisms, and standardization 
of the alternative financing process across VA. 

* The Air Force, Army, and the Department of Navy have already 
centralized some functions in the process. The Air Force is working to 
further centralize these activities in order to decrease the number of 
staff needed to implement these contracts, and to review and approve 
all parts of the process in one location. 

Furthermore, DOE's Federal Energy Management Program provides technical 
and design assistance to support the implementation of energy projects, 
including project facilitators who can guide site officials through the 
process of developing, awarding, and verifying savings from 
alternatively financed projects. 

Agencies Face Measurement and Data Reliability Challenges but Are 
Taking Steps to Address Them: 

Collecting and reporting reliable energy data is critical for agencies 
to assess their progress toward their goals and identify opportunities 
for improvement. According to DOE officials responsible for overseeing 
the collection and reporting of energy information for the federal 
government, there are no federal energy measurement or data collection 
standards, and each agency gathers information differently, using its 
financial systems data and estimating data when necessary through other 
means. For example, NASA and USPS officials reported that their 
agencies use utility payment information to measure and report energy 
use.[Footnote 30] Moreover, DOE officials stated that each site manager 
may use different means to measure and collect energy consumption, 
conservation, and cost data, including handwritten ledger sheets, 
software, cost averaging, and estimation techniques. 

Measuring data at federal buildings is difficult if individual 
buildings do not have meters. Sometimes an entire site is metered by 
the local utility for usage and billing purposes, but not all of the 
buildings on the site are metered individually. Accordingly, energy 
managers cannot always reliably determine the usage in a specific 
building or group of buildings. Without meters, energy teams may be 
unable to pinpoint buildings or areas that need to be improved or 
identify which energy projects have effectively achieved energy 
savings. 

In some instances, agencies' federal energy data have not been 
reliable. DOE officials responsible for annually reporting to Congress 
on agencies' progress toward energy goals acknowledge as much but 
stated that past year data are updated to correct inaccuracies 
discovered by the agencies. 

* In April 2008, the USPS Office of Inspector General reported that 
USPS may be inaccurately reporting energy consumption data to DOE, and 
therefore cannot accurately determine its progress toward meeting the 
energy goals. Among other things, the Inspector General reported that 
USPS did not have a clear process for reporting data on sites' square 
footage and was calculating energy consumption by dividing billed cost 
by an estimated or average cost per kilowatt-hour, which can differ 
significantly from actual consumption. 

* In 2006, a NASA energy management review reported that one of its 
sites had in some cases entered incomplete and erroneous data into the 
database the agency uses to track its progress toward energy 
goals.[Footnote 31] 

* A 2005 report from the VA Office of the Inspector General stated that 
the agency's energy data were not reliable because staff inaccurately 
reported sites' energy consumption and square footage. According to VA 
officials, VA implemented all of the recommendations in the report, 
including those addressing data reliability and, in September 2007, the 
VA Office of the Inspector General closed the report. 

* Air Force officials stated that a thorough data review revealed data 
entry errors at approximately 5 percent of installations. 

Agencies use a variety of mechanisms to verify energy data. For 
example, according to the DOE official who compiles agency data for the 
annual report to Congress, agency data reports are checked for any 
obvious problems by comparing the agency's energy information with 
their data from previous years to identify outliers. He also 
communicates with energy coordinators and compares unit price 
information with a site's recorded energy costs to determine if the 
reported costs appear reasonable. Beyond these checks, DOE relies on 
agencies' headquarters officials and the energy coordinators at sites 
to enter energy information for the sites and verify its accuracy. Many 
officials reported using quality control mechanisms to verify that 
current data match up with past records. These mechanisms include 
automatic database alerts, which notify officials of data that are 
outside specific ranges and thus could be errors. 

Under EPAct 2005, agencies are required to install advanced electrical 
meters by 2012, whenever practical, to help ensure more reliable 
information. Advanced meters are capable of providing real-time data 
that feed directly into an agency's metering database, verifying 
savings from energy projects, and helping site officials to identify 
potential energy savings opportunities. According to the most recent 
OMB energy management scorecards, all six agencies we met with are 
meeting the milestones toward metering all appropriate sites by 
2012.[Footnote 32] 

Some Sites Lack Expertise and Dedicated Energy Management Staff to 
Ensure Adherence to Goals, but Officials Are Taking Steps to Address 
These Challenges: 

To advance energy goals, it is important to have dedicated, 
knowledgeable, energy efficiency staff to plan and carry out energy 
projects. Moreover, according to a June 2007 ASE report, such staff can 
focus on identifying and implementing efficiency projects. However, 
some sites we visited did not have a full-time energy manager. Instead, 
staff members were often assigned part-time responsibility for 
performing energy-related duties in addition to duties unrelated to 
energy management, such as managing site maintenance and providing 
technical support and mechanical design assistance for a site. For 
example, at one DOE site, six to seven different officials have part- 
time energy management responsibilities. At other sites, a GSA building 
manager stated that he spends approximately 15 percent to 20 percent of 
his time on energy goals, and a NASA energy manager reported devoting 
approximately one-third of his time. Finally, officials at a Navy 
installation reported that there is no on-site, dedicated energy 
manager and that the installation needs one if it intends to meet the 
energy goals. In visiting military installations, we found that full- 
time energy managers tended to engage in multiple energy reduction 
activities, while other installations without full-time or experienced 
energy managers tended not to have robust energy reduction programs. 

Furthermore, lack of expertise in energy management and high staff 
turnover may create challenges for negotiating and overseeing 
alternative financing mechanisms. Energy projects funded through 
alternative financing often require a high level of expertise in 
complex areas such as procurement, energy efficiency technology, and 
federal contracting rules. Many agencies told us that without 
experienced personnel, they face challenges in undertaking contracts 
that are necessary to meet energy goals. Officials from multiple 
agencies commented that high turnover rates exacerbate the difficulties 
associated with alternative financing. 

To address these challenges, VA officials stated that they recently 
hired almost 90 permanent facility-level energy managers who will cover 
all VA facilities and focus solely on energy issues. DOD officials also 
reported using resource efficiency managers--contractors that work on- 
site at federal facilities to meet resource efficiency objectives with 
the goal of meeting or exceeding their salaries in energy savings. In 
addition, federal officials are taking part in energy-related training 
courses and undertaking initiatives to reward and support energy 
management personnel. Many agencies reported receiving training on ways 
to improve energy efficiency from a variety of sources, including 
agency-offered internal training, training provided by DOE's Federal 
Energy Management Program, and energy conferences. From fiscal years 
2002 to 2006, agencies reported spending approximately $12.5 million to 
train more than 27,000 personnel in energy efficiency, renewable 
energy, and water conservation. In addition to training, the Federal 
Energy Management Program also recognizes outstanding accomplishments 
in energy efficiency and water conservation in the federal sector 
through an annual awards program. Furthermore, the White House annually 
honors federal agency energy management teams through the Presidential 
Awards for Leadership in Energy Management. Since 2000, these awards 
have recognized such teams for their efforts to promote and improve 
federal energy management and conservation and demonstrate leadership. 

Conclusions: 

The current metric for greenhouse gas emissions--one based on energy 
intensity--is not a satisfactory proxy for assessing agencies' progress 
toward reducing these emissions. There is no consensus on a best 
measure at present; however, there are alternative measures that may 
better track agencies' greenhouse gas emissions than the current 
measure based on energy intensity. Although the previous metric--one 
based on emissions--had limitations, it was more clearly linked to 
emissions and made it easier to assess progress toward reducing those 
emissions. The closer a metric is to approximating the level of 
emissions, the better agencies will be able to determine their progress 
in reducing greenhouse gas emissions. In addition, although the ability 
of agencies to use renewable energy purchase and source energy credits 
towards the goals may further certain federal energy policy objectives, 
it also may enable agencies to achieve compliance with the energy goals 
without actually changing agencies' on-site energy use. 

Although most agencies were able to meet their energy goals for 2007, 
without a strong plan of action agencies may not be well positioned to 
continue to achieve energy goals over the long term, especially in 
light of budget constraints and the $1.1 billion that DOE has estimated 
that agencies will need each year to achieve future energy goals. 
Furthermore, they face challenges with having reliable data and 
retaining dedicated and experienced energy personnel and have not 
adequately planned how to address these challenges in the long term. 
Without guidance from DOE that clearly outlines the key elements for 
effective, long-term energy planning identified in this report that 
could address these challenges, agencies do not have the foundation 
they need to develop plans that will continually adapt to a changing 
energy environment. As a result, agencies are likely to find it 
increasingly difficult to ensure that they will meet energy goals in 
the future. 

Recommendations for Executive Action: 

We recommend that the Secretary of Energy take the following two 
actions. 

* In conjunction with the Federal Environmental Executive and the 
Director of the Office of Management and Budget, re-evaluate the 
current measure for greenhouse gas emissions and establish one that 
more accurately reflects agencies' performance in reducing these 
emissions to help determine whether agencies are making progress over 
time. 

* To help agencies address the challenges they face in meeting energy 
goals into the future, finalize and issue guidance that instructs 
agencies in developing long-term energy plans that consider the key 
elements of effective plans identified in this report. 

Agency Comments and Our Evaluation: 

We provided a draft of this report to the CEQ, DOD, DOE, GSA, NASA, 
OMB, USPS, and VA for their review and comment. In commenting on a 
draft of this report, NASA and USPS generally agreed with our findings, 
conclusions, and recommendations and provided written comments included 
as appendixes II and III, respectively. GSA responded by e-mail on 
September 8, 2008, stating that it concurred with our report. VA 
neither agreed nor disagreed with our report and provided written 
comments included as appendix IV. The Council on Environmental Quality, 
DOD, DOE, and OMB did not provide any comments on our draft. For those 
agencies who submitted technical and clarifying comments, we 
incorporated those as appropriate. 

In addition, VA expressed concern that it was not afforded the 
opportunity for an exit conference. However, we note that we offered 
the opportunity for such a meeting to the Office of Asset Enterprise 
Management, the office within VA responsible for energy management and 
designated by VA at the outset of our engagement as the main point of 
contact. Furthermore, the Office of Asset Enterprise Management 
provided written comments on a preliminary draft that we incorporated 
into the subsequent draft, as appropriate. 

We are sending copies of this report to interested congressional 
committees and Members of Congress and the Chairman of CEQ; the 
Administrators of GSA and NASA; the Director of OMB; the Postmaster 
General and Chief Executive Officer of USPS; and the Secretaries of 
Defense, Energy, and VA. We also will make copies available to others 
upon request. In addition, the report will be available at no charge on 
the GAO Web site at [hyperlink, http://www.gao.gov].

Appendix I: Scope and Methodology: 

To determine the extent to which agencies met energy efficiency, 
greenhouse gas emission, and renewable energy goals, we analyzed data 
on agencies' performance in meeting these goals using draft agency 
energy data, as of July 2008, for fiscal year 2007, which were reported 
by the agencies to the Department of Energy (DOE) for use in DOE's 
Annual Report to Congress on Federal Government Energy Management and 
Conservation Programs. We considered agencies to have met the energy 
efficiency goal for fiscal year 2007 if they reduced energy intensity 
by at least 6 percent from the 2003 baseline. We also met with 
officials from DOE to understand how the data are developed. 

To assess the agencies' progress in each of these areas in recent 
years, we reviewed energy efficiency, greenhouse gas emission, and 
renewable energy goals, as established in current and previous statute 
and executive orders--the Energy Policy Act of 2005, Executive Order 
13123, and Executive Order 13423. We also analyzed data on agencies' 
performance in meeting the goals, as reported in DOE's annual report to 
Congress for fiscal year 2005. Furthermore, we analyzed draft data from 
these annual reports for fiscal years 2006 and 2007. In addition, we 
met with officials from DOE, the Office of the Federal Environmental 
Executive, and the Office of Management and Budget to gain their 
perspective on the goals and an understanding of their roles in 
overseeing the statue and executive orders. In assessing agencies' 
performance for 2007 and progress in recent years, we determined these 
data from DOE's annual reports to be sufficiently reliable for our 
purpose, which was to convey what the agencies reported to DOE about 
the status of meeting the energy goals. 

To determine the extent to which the agencies are poised to meet future 
energy goals, we selected six agencies on the basis of several 
criteria, including the following: (1) energy consumed: of the agencies 
reporting energy data to DOE, these six agencies together accounted for 
nearly 94 percent of the energy consumed in standard buildings in 
fiscal year 2005; (2) level of investment in energy and utility savings 
performance contracts; (3) amount of renewable energy purchased, and 
self-generated; and (4) estimated carbon emissions. Because these six 
agencies accounted for nearly 94 percent of the energy consumed in 
standard buildings in fiscal year 2005, our findings for these agencies 
may have great implications for the federal government as a whole. We 
visited a minimum of two sites per agency to understand efforts toward 
meeting energy goals at the local level. 

To ensure that we had a variety of sites, we selected the sites on the 
basis of both high and low reductions in energy intensity from 2003 to 
2006, geographic location, site size, and agency recommendation, among 
other criteria. The six agencies and the sites we visited are listed in 
table 1.

We obtained and analyzed documentation and met with headquarters 
officials and officials responsible for energy management at the sites 
from the six agencies. In addition, we systematically reviewed these 
interviews to determine what primary challenges agencies face and the 
tools they use to meet energy goals. We used general modifiers (i.e., 
most, several, some, and a few) to characterize the extent to which 
agencies were facing and addressing the challenges we found. We used 
the following method to assign these modifiers to our statements: 
"most" and "many" represents four to five agencies, "several" and 
"some" represents three agencies, and "a few" represents two agencies. 
We also systematically reviewed documents and interviews to determine 
whether agencies' long-term plans contained key elements as identified 
by our past work.[Footnote 33] For our review of agencies' long-term 
energy plans, we reviewed planning documents obtained from agency 
officials that laid out agencies' efforts to achieve the energy goals 
beyond 1 year. We also met with officials from the Alliance to Save 
Energy to get their perspective on challenges facing the federal 
government. Finally, we participated in DOE's Webcast training on 
energy savings performance contracts offered by DOE and attended 
GovEnergy, an energy training workshop and exposition for federal 
agencies. 

We conducted this performance audit from May 2007 through September 
2008 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives.

Dear Mr. Gaffigan and Mr. Dorn: 

The U.S. Postal Service would like to take this opportunity to formally 
comment on the findings in the draft report entitled, Federal Energy 
Management: Addressing Challenges Through Better Plans and Clarifying 
the Greenhouse Gas Emissions Measure Will Help Meet Long-term Goals for 
Buildings (GAO-08-977). 

We generally agree with the findings contained in the draft report 
about the Postal Service efforts to reduce energy consumption and 
increase renewable energy use, however, we need to re-emphasize our 
position on specific issues. The Postal Service is reducing its energy 
consumption by focusing on those opportunities that provide a strong 
return on investment (ROI). Our objective is to be as energy efficient 
as is life cycle cost effective for both new construction and our 
existing buildings. In regard to renewable energy, given the current 
economics associated with the technologies, energy conservation is 
quite often a far better investment of financial resources. We are 
continuing to install and evaluate renewable technologies and will 
implement in those applications that are most financially viable. 

By focusing on energy conservation and those opportunities that provide 
a strong ROI, the Postal Service is on target to meet the federal 
energy reduction objectives in its portfolio of 34,000 buildings 
without the use of outside financing or the purchase of credits. In 
addition, a national energy management plan is being reviewed by Postal 
Service leadership, identifying goals and standards for energy 
reduction and consumption for facility energy management, fleet 
management, fuel use and energy consumption. This plan will be released 
in the next 30 days. 

If you or your staff wishes to discuss any of these comments further, I 
am available at your convenience. 

Sincerely,

Signed by:

Footnotes: 

[1] Carbon dioxide is overwhelmingly the largest component of 
greenhouse gas emissions from energy use. Most carbon dioxide emissions 
in the United States result from the combustion of fossil fuels, the 
source of most of the electricity consumed in the United States. 

[2] Renewable energy is produced from sources that cannot be depleted; 
such energy includes solar, wind, biomass, and geothermal. 

[3] For ease of presentation, we refer to the greenhouse gas emission 
direction as an energy goal. 

[4] Using DOE-determined criteria, certain sites and equipment may be 
exempted or excluded from having to meet the energy efficiency goals. 

[5] Congress passed the Energy Independence and Security Act of 2007 
(Pub. L. No. 110-140) in December 2007, which expanded the energy 
efficiency goal of EPAct 2005 and ultimately matched the goal of E.O. 
13423 through fiscal year 2015. However, it was silent on specific 
greenhouse gas emission and renewable energy goals for federal 
agencies. We did not include the new law in the scope of our study 
because the law was passed in fiscal year 2008, which is beyond the 
time frame covered in our report. 

[6] According to the U.S. Postal Service, while the agency is subject 
to the energy efficiency goal as laid out in EPAct 2005, it is neither 
subject to the act's renewable energy goal, nor is it subject to the 
energy goals laid out in the executive orders. However, it tries to 
comply with the spirit and intent of the energy goals. 

[7] Small on-site, renewable energy generation projects that do not 
incur fuel costs, are unmetered, and are located on the customer side 
of a site's energy meter energy conservation project are not included 
in the total Btu-per-gross-square-foot calculations used for energy 
efficiency goals. 

[8] Our work focused on the energy components of these goals, not on 
cost components. Although agencies are directed to achieve these goals 
with cost-effective or economically sound measures, cost savings is not 
the objective of these goals.

[10] GAO, Energy Savings: Performance Contracts Offer Benefits, but 
Vigilance Is Needed to Protect Government Interests, GAO-05-340 
(Washington, D.C.: June 22, 2005). 

[11] Vehicles/equipment and sites not subject to the statute and 
executive orders account for approximately 64 percent and 4 percent, 
respectively, of the energy used in fiscal year 2007. 

[12] According to USPS, the agency is not subject to EPAct 2005's 
renewable energy goal. However, it tries to comply with the spirit and 
intent of the goal. 

[13] Renewable energy can be purchased as renewable energy certificates 
(REC), which provide credit for the technological and environmental 
benefits of using electricity generated from renewable sources. A 
certificate can be sold separately from the underlying electricity with 
which it is associated. Once the REC is sold separately from the 
underlying electricity, the electricity is no longer considered 
renewable. Buyers of RECs can claim the credit for the renewable energy 
and may offset a percentage of their annual electricity use when green 
power products may not be available locally. 

[14] Not all agencies have industrial and laboratory buildings. 

[15] Agencies may apply to DOE for exclusion of certain buildings from 
the energy efficiency goal for a number of reasons, such as if a 
building is crucial to an agency's national security function. With the 
change from E.O. 13123 to EPAct 2005, the criteria for exclusions 
changed; as a result, the number of buildings meeting these new 
criteria and therefore eligible to be excluded also changed, resulting 
in corresponding changes to the buildings included in the energy 
intensity calculation.

[18] While EISA 2007 is outside the scope of our engagement, it may 
help agencies address some of the challenges we identified. For 
example, the act requires agencies to have an energy manager 
responsible for overseeing energy efficiency criteria that covers, at a 
minimum, federal sites constituting at least 75 percent of site energy 
use at each agency.

energy services companies that have been prequalified via a competitive 
process - that the federal government has awarded since 1998. The 
figure assumes there is no inflation in cost per energy unit saved 
through 2015. 

[24] The Energy Conservation Investment Program is a centrally managed, 
project-oriented, DOD-wide account which is programmed annually and 
represents the only direct DOD investment in conservation. The program 
is funded strictly through appropriations and requires congressional 
notification prior to project execution and periodic update of 
execution status.

[30] USPS is in the process of developing and implementing two new 
systems that will allow officials to collect and track actual 
consumption data. According to USPS officials, the Enterprise Energy 
Management System will enable USPS to locally and remotely monitor 
energy usage and demand, as well as consolidate energy-related data 
from existing applications and facilities into a centralized location. 
The Utility Management System will uniformly collect actual utility 
energy cost and consumption data.
