Since its inception, the Department of Energy (DOE) has administered programs for reducing
energy consumption by influencing consumer choice and improving technology. Starting in 1975 Congress authorized
programs to address the energy and water consumption of consumer products, such as appliances, and commercial and
industrial equipment used in buildings. In 1978, Congress authorized a mandatory national standards program having binding
targets and timetables for the energy performance and energy consumption of appliances and, in the Energy Policy Act of
1992 (P.L. 102-486), for commercial and industrial equipment (“products and equipment”).
Early in the national standards program, Congress required DOE to revise certain standards according to a set schedule, often
specific to the product or equipment. Congress later required DOE to conduct an every-six-year review of efficiency
standards for products and equipment in the Energy Independence and Security Act of 2007 (P.L. 110-140). Subsequent
Congressional action, the American Energy Manufacturing Technical Corrections Act (P.L. 112-210) clarified this
requirement for certain commercial and industrial equipment. DOE has accumulated a backlog of standards due for revision,
and in its August 2021 Report to Congress on the national standards program tallied 33 rulemakings that were late relative to
a statutory deadline.
DOE has previously set polices and used criteria on whether to issue new and revised standards. These would have reduced
the number of rulemakings by applying a threshold of energy savings or would have sequenced the rulemakings according to
a set of criteria. Most recently, in 2020, DOE issued a policy to apply a quantitative threshold, believing it would “eliminate
from further consideration those potential standards that are projected to result in substantially lower energy savings.” The
policy was reversed in the Biden administration.
In addition to reducing the backlog of rulemakings, sequencing rulemakings would realize the benefits of significant
conservation of energy as soon as possible. Delaying revisions delays the energy savings that would accrue under a newly
revised rule, which by law must be more stringent. Performing the most effective rulemakings first would capture the largest
benefits sooner.
Any method that reduces the number of rulemakings will have some consequences. A CRS analysis shows that, had DOE
applied the energy threshold it established in 2020 during the years 2013 to 2017, it would have not promulgated 14
rulemakings. Doing so would have foregone 1.625 quadrillion British thermal units (Btu) of energy savings, or about 1.5% of
annual consumption in the United States.
Congress has options that would help DOE reduce the backlog. First, Congress may wish to prioritize revisions with
significant conservation of energy by specifying a minimum quantity or percent of energy saved, instructing DOE to test any
potential revision against this minimum. If the minimum is not met, Congress could instruct DOE not to proceed with
revising a standard. This would likely reduce the number of revisions DOE must complete. Second, Congress could require
DOE to conduct a periodic study of the impacts of many standards. Such a study could determine the expected energy
savings of the standards, and DOE could use these insights to prioritize those standards for which it estimates the highest
conservation of energy. Third, Congress may wish to require DOE to prepare a report assessing the energy efficiency
potential, or how much energy could be saved both by setting more stringent standards and including additional appliances
and equipment in the national standards program. This could cover consumer products and commercial equipment of any
type, not just those currently regulated by DOE and thus might capture additional opportunities for energy savings. There
may be other options that do not involve changing how DOE sets its priorities, not analyzed here, including increasing the
number of staff available with an aim toward clearing the backlog faster. Congress could also allow the current approach to
prevail. This would result in no additional administrative costs to the program. In addition, the current approach would
capture more energy savings than the threshold approach, noted above, if such rulemakings were to be completed rather than
remain in a backlogged state.

DOE's Appliance and Equipment Standards Program: Addressing the Backlog

Introduction
Since its inception, the Department of Energy (DOE) has administered programs aimed at
reducing energy consumption by influencing consumer choice and improving technology.
Reducing energy consumption can lead to a reduction in the impacts on human health and the
environment because of the reduction in extraction of primary energy resources and their
processing, conversion, delivery, and end use to provide energy services.1 For the residential
consumer or the firm, the use of both more efficient consumer products, such as household
appliances, and commercial and industrial equipment, can lead to savings in monthly energy bills,
which can lead to lower total cost of ownership.
Starting in 1975 Congress authorized programs to address the energy and water consumption of
consumer products and commercial equipment used in buildings.2 The program was first
authorized with the Energy Policy and Conservation Act (EPCA, P.L. 94-163) and later amended
by numerous acts.3 In 1978, Congress authorized a mandatory national standards program and
tasked the Secretary of Energy with setting binding targets and timetables for the energy
performance of the consumer products used in buildings, provided those standards met certain
statutory criteria.4 One of these criteria is the admonition not to set a standard that does not
achieve “significant conservation of energy”; however, EPCA, as amended, does not elaborate
further on an explicit quantitative definition. DOE rulemakings and court cases have furthered
debate about what comprises significant conservation of energy.
DOE administers the national standards program for more than 60 categories of products and
equipment, and also issues test methods, conducts enforcement activities, oversees certification,
and revises the standards themselves on a schedule set by Congress. Over the last several years,
DOE has accumulated a backlog of standards due for revision but not yet completed on the
schedule set by Congress. This backlog has been the subject of court cases and Congressional
hearings.5
This report analyzes the history and status of the backlog of revisions to the national standards
program. As stated in statute, the purpose of the national standards program is to “conserve
nonrenewable energy resources”;6 the report does not conduct an independent assessment of this
stated purpose. Through statute and later oversight hearings, Congress has indicated a preference
for DOE to address the overdue revisions to the standards that accumulate in the backlog.7 The

submit a report to Congress regarding each new or revised energy conservation or water use standard which the
Secretary has failed to issue in conformance with the deadlines established in the Energy Policy and Conservation Act.
Such report shall state the reasons why the Secretary has failed to comply with the deadline for issuances of the new or
revised standard and set forth the Secretary’s plan for expeditiously prescribing such new or revised standard.” 42

report discusses the current approach and also provides prioritization options for how to address
the backlog, and analyzes what the effects of these options might be. The scope of these effects
include the change in the quantity of energy conserved and changes in indicators not explicitly
called for by the statute. There may be other options for clearing the backlog that do not involve
prioritization, including increasing the number of staff available with an aim toward clearing the
backlog faster, but these options are not discussed here except briefly. A further option is to
continue with business as usual, which the report discusses in a later section, “Comparison to
Current Approach.”
This report is organized into sections discussing the national standards program; how DOE issues
the standards; DOE’s past attempts to prioritize the order in which it completes these standards;
other possible methods of prioritizing; the effect of prioritization and its impacts; and, lastly,
options for Congress.
DOE’s National Standards Program
Overview
The Department of Energy has implemented the EPCA authority for over 60 categories of
products and equipment to achieve energy conservation. Some of the better-known covered
products and equipment include refrigerators, furnaces, and commercial air conditioning. The
regulations also cover less visible equipment and equipment parts such as transformers and
furnace fans. According to a 2017 DOE estimate, the program was expected to deliver energy
savings of 71 quadrillion British thermal units (quads) from inception through 2020,8 which is
three-quarters of one year’s primary energy production in the United States.9
How the Program Works10
The program sets minimum efficiency standards or maximum water11 or energy use standards for
both consumer products and commercial and industrial equipment (“products and equipment”);
the standards that apply to these products and equipment are established by Congress in law or by
the Secretary of Energy following EPCA. The effect of the standards regulations is to remove
from the market those products and equipment that do not comply with the standard. The
standards thus reduce the choice set a consumer or firm would face so that less energy-efficient
and higher energy-consuming products are no longer part of that set.
The national standards program includes features to ensure compliance at the point a product
leaves the manufacturer and well-defined test procedures to determine the energy consumption of
the products and equipment. As with the energy conservation standards, the test procedures are
codified in the Code of Federal Regulations (C.F.R.).

DOE's Appliance and Equipment Standards Program: Addressing the Backlog

DOE’s analyses in support of the national standards program estimate the energy savings in units
of quads. One quad is the combustion energy in roughly one trillion cubic feet (Tcf) of natural
gas; the United States consumed roughly 30 Tcf of natural gas in 2021.12 Annually, the United
States consumes approximately 100 quads of energy from all sources.13
Statutory Requirements of the National Standards Program
The statute that authorizes the national standards program, the Energy Policy and Conservation
Act, as amended, requires that new or amended standards must result in significant conservation
of energy, be technologically feasible, and be economically justified.14 EPCA is not specific on
what comprises “significant conservation of energy,” and DOE currently has no articulated
position.15
For the “technologically feasible” criteria, EPCA requires, at the proposed rule stage, that the
“Secretary [of Energy] shall determine the maximum improvement in energy efficiency or
maximum reduction in energy use that is technologically feasible.”16
In setting new or revised energy conservation standards, the Secretary of Energy considers the
energy savings, cost (or savings) to consumers and firms, and cost (or savings) to the
manufacturers as part of the determination whether “the benefits to the nation of the standards ...
outweigh the burdens.”17 If the Secretary finds in the affirmative for a candidate standard, the
Secretary issues that standard in regulation and places it in the C.F.R.
Six-Year Reviews
EPCA, as amended, requires DOE either to publish a determination that a standard does not need
amending or issue a notice of proposed rulemaking for a newly-revised standard within six years
of a previous final rule for a given product, piece of equipment, or class of either.18 An example in
which DOE opted to revise the standard was in the case of computer room air conditioners. DOE
initiated the periodic review in 2019 with a request for information.19 Later, in 2022, DOE issued
a proposed rule.20 DOE has stated that it typically needs at least three years to complete a
rulemaking to revise an energy conservation standard.21

On a case-by-case basis, Congress has established schedules by which DOE must conduct
periodic rulemakings. The Energy Independence and Security Act of 2007 (EISA 2007, P.L. 110-
140), for example, set a number of milestones for rulemakings for general service lamps.22 DOE
later issued a final determination in 2019 that it would not revise standards for general service
incandescent lamps.23
Promulgation of Standards
History of Initial Phase of Standards Program
The first set of binding standards provides an illustration of how over time DOE and/or Congress
has revised the energy conservation standards. The national standards program began with a list
of 13 product categories to be covered.24 Generally speaking these were household appliances
such as refrigerators. Congress tasked DOE with setting appropriate standards by rulemaking and
also gave DOE the option to decline to set a standard if, in the Secretary’s judgment, it failed to
meet statutory criteria. In 1982 and 1983, DOE did in fact decline to set standards for eight of
these 13 congressionally-authorized products after concluding by rulemaking that such standards
would not achieve “significant conservation of energy.”25 This first use of the “significant
conservation of energy” test was the subject of litigation a few years later, and the debate about its
meaning continues.
With the National Appliance Energy Conservation Act of 1987 (NAECA, P.L. 100-12),26
Congress enacted standards for 11 product categories into law.27 Congress specified the
quantitative standard and the date by which manufacturers were to comply.
Figure 1 shows the various product categories in a timeline, the earliest points of which
correspond to the NAECA-specified standards. These energy conservation standards all took
effect by 1992. Subsequent points in the timeline—an icon depicts each product category—show
the revisions to the energy conservation standards. In some cases, Congress legislated the
revisions; for example, EISA 2007 set the quantitative energy conservation standard for some
products and equipment. In other instances, Congress left it to DOE to conduct a rulemaking to
decide the quantitative level of the revised standard.

22 See discussion at 84 Federal Register 71628 (December 27, 2019).
23 84 Federal Register 71626 (December 27, 2019).
24 Although there were originally 13 categories of products, the number of these original 13 for which standards were to
be issued was reduced to 11 after NAECA combined two categories to make one, “refrigerators and freezers,” and
deleted “humidifiers and dehumidifiers.” Congress left it to DOE’s discretion whether to issue standards for one of
these, televisions, which it did not. See discussion at 52 Federal Register 46369 (December 7, 1987).

Late Rulemakings
Three statutes—NAECA; the National Appliance Energy Conservation Amendments of 1988
(NAECA 1988, P.L. 100-357); and the Energy Policy Act of 1992 (EPAct92, P.L. 102-486)—
required DOE to review specific standards by rulemaking at time intervals varying, case by case,
from three to eight years later. DOE states that after EPAct92 the backlog of late rulemakings
began to accumulate.28
Congress required DOE to make an initial report on late rulemakings per Section 141 of the
Energy Policy Act of 2005 (EPAct05, P.L. 109-58). In the first such report, DOE noted that by
1997 it had missed 17 statutory deadlines for issuance of standards, a number that had increased
to 25 by 2005.29 Congress further required DOE to issue semi-annual reports until such time as
the backlog was retired. DOE published the first report in January 2006 and established a
schedule by which it planned to retire the backlog.30 This schedule was in large part ratified later
that year in a consolidated consent decree.31
By 2014, DOE was having to address the first cohort of standards that were due for six-year
reviews. Section 305 of EISA 2007 had required DOE to conduct every-six-year reviews of
consumer product and commercial and industrial equipment, and the American Energy
Manufacturing Technical Corrections Act (AEMTCA, P.L. 112-210) clarified the timeline for
certain commercial and industrial equipment standards.
The 2021 report to Congress indicates 33 rulemakings that were late relative to a statutory
deadline.32 (See Figure 2.) Of these, 25 had missed the every-six-year review deadline.

Notes: Reports from February 2013 to August 2014 did not provide a cumulative total, and, as a result, the top
line, “rulemakings that have missed a statutory deadline,” is truncated.
The Pace of Rulemakings
The pace at which the accumulated late rulemakings can be retired depends on DOE’s capacity.
At any given time, DOE has a large number of rulemakings in progress. In the Spring 2022
Unified Agenda of Regulatory and Deregulatory Actions,33 DOE listed 20 energy conservation
standards in the pre-rule phase, 46 in the proposed rule stage, and 6 in the final rule stage.34
Congress has taken note of the backlog. In March 2019 the House Energy and Commerce
Committee, Subcommittee on Energy, held a hearing after DOE had missed the deadlines for
completion of 16 of the every-six-year reviews, according to one estimate.35 Four of the

rulemakings accomplishing such reviews had been signed and dated in 2016 but not yet
published.36 A federal court ordered DOE to issue those rulemakings,37 which DOE then
promulgated in January 2020.38 Nonetheless, the backlog of rulemakings persisted, as illustrated
in Figure 2.
Summary of Current Approach
DOE’s current approach is to maintain a list of rulemakings for energy conservation standards
that are either due for revision soon or are late and deemed to be part of a rulemaking backlog. In
the reports to Congress mandated by EPAct05, DOE identifies its top priority rulemakings and a
multi-year schedule of when (i.e., in which calendar quarter) DOE might expect to issue one
standard for each of the products in backlog. DOE also describes its near-term plans for
rulemakings in the semi-annual, government-wide Unified Agenda.39 Although it can vary, DOE
completed roughly seven rulemakings per year from 2013 to 2017. The rulemaking backlog
continues to increase and has roughly doubled since 1997 to where it now stands at 33 late
rulemakings.40
Previous Attempts at Prioritization
DOE has issued documents to prioritize future rulemakings, take stock of its backlog, and set
principles to establish the sequence of rulemakings. The principles these documents include are
broad, and DOE has not explained in any detail what has motivated its plans for sequencing the
rulemakings. For example, in DOE’s most recent Statement of Regulatory and Deregulatory
Priorities,41 it discussed three priority rulemakings, one of which was to revise energy
conservation standards for one particular category of equipment, commercial water heaters. The
Statement noted that the rulemaking would save “up to 1.8 quads over 30 years and the net
benefit to the Nation would be between $2.26 billion and $6.75 billion,” but did not say which
standards rulemakings DOE would address next.
DOE has published reports to Congress and policy documents that do use a sequencing approach
as a way of planning its regulatory activities to revise the standards for the various categories of
products and equipment. DOE states which standard or standards it plans to revise next. In policy

36 These four rulemakings included the following products and equipment: portable air conditioners, uninterruptible
power supplies, air compressors, and commercial packaged boilers. Their status is explained at 85 Federal Register

documents, DOE has developed a multi-factor method, applying several criteria, to decide which
standard to revise next.
DOE has also taken another approach, sometimes concurrently with the above, to determine one
at a time whether a standard might save sufficient energy or offset the use of barrels of oil to
warrant revision. Should the standard not meet the threshold, the process would conclude with a
final rule stating no new standard was needed.
The following two sections discuss these approaches.
Sequencing Approach
Multi-Factor Prioritization: The 1996 Process Rule
In 1996 DOE promulgated the so-called Process Rule—a set of procedures used to set efficiency
standards and test methods for consumer products.42 The Process Rule included a multi-factor
prioritization scheme. DOE used this prioritization scheme to determine the sequence in which
rulemakings were to be performed. Specifically, the Process Rule prioritized those rulemakings
with higher conservation of energy. At the same time, it did not reduce the number of rulemakings
overall. Roughly 10 years after issuing the Process Rule, DOE noted that its effect had been to
prioritize conservation of energy but had the unintended consequence of contributing to a backlog
of uncompleted statutorily-mandated standards.43 DOE’s prioritization scheme at that time did not
include reducing the number of rulemakings; rather, it affected the order in which DOE
performed the rulemakings.
Policy Documents That Proposed Sequences
DOE’s required semi-annual reports to Congress, discussed above in “Late Rulemakings,”
included discussion and analysis of which revisions mandated by Congress were late or in
“backlog” status. The reports further included a multi-year schedule of when (i.e., in which
calendar quarter) DOE might expect to issue one standard for each of the products in backlog.44
DOE’s success in this approach varied, and with each succeeding semi-annual report DOE would
provide an update on how it had met the previous multi-year schedule.
The 2021 Report to Congress included in its list of late rulemakings 25 that were overdue for the
every-six-year review requirement.45 The report further includes a list of rulemaking steps DOE
was taking for a number of energy conservation standards and the anticipated completion date,
but does not explain how it arrived at the sequence. The multi-year schedules have included the
backlog standards noted above together with new standards required of DOE by act of Congress.
DOE is responsible for addressing all these standards-setting activities concurrently along with
test procedures and coverage determinations, among other things.

42 The Process Rule is codified at 10 C.F.R. §430, Subpart C, Appendix A.
43 U.S. Department of Energy, Energy Conservation Standards Activities: Submitted Pursuant to Section 141 of the
Energy Policy Act of 2005 and to the Conference Report (109-275) to the FY2006 Energy and Water Development
Appropriations Act, Washington, DC, January 2006, p. vii. DOE noted that two of the three revisions to standards using
the Process Rule took much longer than the expected 36-month duration.

Threshold Approach
DOE has previously set criteria by which it could cull standards that did not meet certain criteria.
None are still in effect. These criteria were intended to be applied, one at a time, when DOE set or
revised a single standard. DOE would make its estimate of the energy savings expected over 30
years, compared to the incumbent product or equipment. The following subsections discuss these
criteria.
Considering each standard separately disregards how the rulemaking might combine with other
rulemakings to affect overall costs and benefits. Several standards taking effect concurrently may
have cumulative effect on the consumption of energy commodities such as electricity and natural
gas. This cumulative effect may change the price of energy commodities, which in turn may
affect consumption as consumers and firms react to the new price—an effect that would be
missed in the one-at-a-time approach.
DOE conducts analyses of impacts of the standards as a matter of routine during rulemakings and
could use this type of analysis as guidance for setting priorities. Specifically, DOE analyzes the
impact of a potential standard by comparing the energy used by the product or equipment
currently in use to a product or equipment with better energy performance. For example, in the
case of furnaces DOE utilized a model that considered units sold over the span of 30 years.46 This
so-called “vintage stock” model accounts for the removal from service of appliances after they
reach a certain age. The new appliances take the place of the old ones, and these new appliances
may have improved energy performance. The analysis adds up the incremental improvement in
energy performance and treats these as a benefit of the new standard.47 The following sections
provide examples of DOE’s use of such analyses for setting priorities in past policymaking and
envisages possible future such uses.
Initial Phase of National Standards Program
In rulemakings in the early 1980s, DOE interpreted EPCA as having delegated to DOE the task of
deciding what comprised “significant conservation of energy.” DOE defined and applied a three-
part threshold test during rulemakings in 1982 and 1983; satisfying any one part would qualify
the potential standard as having achieved significant conservation of energy. These three parts
were saving either: one-sixth (16.67%) of energy consumption over one year, relative to the
market-incumbent appliance; or 1% of national electricity use; or 10,000 barrels per day of oil (or
its Btu-equivalent in volume of natural gas).48 DOE determined that none of the six appliances
under consideration satisfied the test and concluded the “no standard” rulemakings without
promulgating energy conservation standards, a situation discussed in more detail earlier in
“History of Initial Phase.”

46 “National cumulative energy savings (NEScum) are the sum of the annual NES over the lifetime of products shipped
during the analysis period.” See U.S. Department of Energy, “Technical Support Document: Energy Efficiency
Program for Consumer Products and Commercial and Industrial Equipment: Residential Furnaces,” August 30, 2016, p.
10-18, at https://www.regulations.gov/document/EERE-2014-BT-STD-0031-0217.
47 Of note, while DOE’s analysis can consider a variety of levels of energy performance, DOE’s ultimate choice of
standard must be at a level of energy performance that is economically justified. This may rule out the maximum level
of performance that is technologically achievable—a level sometimes called “max tech.”
48 48 Federal Register 39385a (August 30, 1983). DOE used a model that calculated the energy consumption at the
residence for oil- and natural-gas consuming appliance. For electricity DOE calculated the energy consumed at the
power plant, or roughly three times the energy consumed by the appliance.

2020 Revision to the Process Rule
For a time, DOE had a threshold of 0.3 quads in place, starting in 2020 with a revision to the
Process Rule.49 This threshold meant that, for any rulemaking underway for a new or revised
standard, if DOE were to estimate it would save fewer than 0.3 quads, DOE would not proceed to
issue the standard. The purpose was to “eliminate from further consideration those potential
standards that are projected to result in substantially lower energy savings.”50 The policy took
effect in 2020; however, DOE reversed the policy in 2022 without ever having applied it.51 The
following section, “Effect of Applying a Threshold on the Number of Rulemakings,” analyzes
what would have been the impact, had this threshold been applied to a group of standards
rulemakings over several years. The analysis is a counter-factual, because DOE’s policy was not
in effect during the time interval, but the analysis is illustrative.
Effect of Applying a Threshold on the Number of Rulemakings
CRS used DOE’s estimates of energy savings for rulemakings from 2013 to 2017, roughly one
Presidential term of office, to determine the potential effect of a threshold. CRS applied a
threshold at the same level DOE promulgated in 2020, or 0.3 quads.
In its analysis, CRS found 14 rulemakings would have been culled by the threshold. In the
counterfactual situation in which DOE’s 0.3-quad threshold had been in effect, DOE would not
have revised those standards. CRS found that the standards that would have been culled would
have accounted for 8% of the site energy saved relative to all the rulemakings of the four-year
period.52
Figure 3 shows the rulemakings just discussed and their projected energy savings. The figure
displays the rulemakings in order of increasing site energy savings, moving left to right along the
horizontal axis.
Some equipment is known as “ASHRAE equipment”—ASHRAE is the American Society of
Heating, Refrigerating and Air-Conditioning Engineers—to acknowledge the standards issued
independently by that organization in conjunction with the American National Standards Institute
(ANSI) and the Illuminating Engineering Society (IES). The CRS analysis does not include
standards DOE revises after ASHRAE publishes a new standard, the so-called ASHRAE trigger,
as these have unique statutory and other requirements DOE must follow in determining whether
or not to update the energy conservation standards.53 ASHRAE equipment includes “generally,
commercial water heaters, commercial packaged boilers, commercial air conditioning and heating
equipment, and packaged terminal air conditioners and heat pumps.”54

52 This calculation used the energy consumed at the site by the product or equipment, but in the case of electrical
appliances, the calculation also included the energy needed to generate the electricity in the first place. Using a
different method of accounting for the energy that DOE published in 2012 (76 Federal Register 51281, August 18,
2011) would result in an additional three standards passing the test.

One of the effects of culling standards according to a criterion or criteria is to alter the costs and
benefits delivered by the national standards program. DOE has estimated the savings to
consumers and firms that accrue from reduced energy costs, net of any higher first cost of the
appliance or repair or other costs. DOE and non-governmental organizations have pointed to this
benefit as among the chief reasons for the national standards programs.55 Figure 4 shows the net

present value (NPV)56 for the rulemakings for the category of product and equipment in the same
left-to-right order as Figure 3. Note while there is, by design, a steady increase moving left to
right in Figure 3, the NPV plot of Figure 4 does not increase in the same steady, monotonic
fashion. This illustrates the difficulty of choosing or discarding potential standards based on one
measure or the other, and shows that some standards may be more cost-effective even if their total
energy savings is lower.
The 14 standards that fell below the 0.3 quad threshold, site energy basis, would have saved
consumers and firms $1.4 billion at 3% and $0.6 billion at 7% discount rates. The comparison is
not completely rigorous because the 14 standards do not run concurrently or use the same base
year for the NPV calculations; the analysis neglected the impact of the reduced energy
consumption on energy prices; the analysis did not take account of substitution between different
appliances or their collective impact on energy commodities; and the analysis assumes no new
standards for 30 years and makes other assumptions about the future that might be overtaken by
events.

56 The calculation of net present value (NPV) takes account of purchase price in year zero and cash flow in all future
years but mathematically discounts (i.e., reduces) the amount of savings before adding all of them together into one
“present value.” The savings in years far off in the future contribute less to NPV because the calculation compounds the
mathematical discount factor. Interested readers may find further details in OMB Circular A-4, which says: “If we take
the rate that the average saver uses to discount future consumption as our measure of the social rate of time preference,
then the real rate of return on long-term government debt may provide a fair approximation. Over the last thirty years,
this rate has averaged around 3 percent in real terms on a pre-tax basis.” Office of Management and Budget, Circular

Other Methods of Prioritizing
The previous section discussed methods of addressing the backlog that involve either sequencing
the rulemakings according to some set of criteria or method; or setting and applying a threshold
of energy savings, to cull standards from the revisions process, one at a time. This section of the
report discusses two additional approaches, piloted by DOE and other organizations, which if
implemented could prove useful and provide greater analytical power.
In one of these approaches, DOE would be anticipatory and analyze groups of standards. These
groups could be standards due for the every-six-year review or standards corresponding to the
Congressional Research Service

14

link to page 14 DOE's Appliance and Equipment Standards Program: Addressing the Backlog

type of energy service they provide (e.g., thermal comfort). Another approach would be to
broaden the analysis to include all energy-consuming devices, not just those already covered by
the national standards program.
Analyzing Many Standards at Once
First, DOE could prioritize using the information gleaned from an analysis of many standards,
one at a time, and comparing the marginal benefits of each. The analyses would be similar in
scope to those performed when applying a threshold—see “Threshold Approach,” above—but
would be applied to larger numbers of standards. The results of the analyses would allow DOE to
make a determination about the relative importance of the rulemakings and establish a sequence
to perform them. DOE could use this information to establish a clear top-to-bottom rank order.
One way to establish the sequence would be according to the quantity of energy saved, although
other options include ranking by cost-effectiveness or marginal cost to the consumer.
DOE has conducted analyses of many standards at once in past exercises; however, some of these
considered the impacts of the standards one at a time, in isolation from one another. One such
example took place in 2002, in which DOE published a list of possible actions following a
recommendation from the National Energy Policy Development Group.57 DOE evaluated the
energy savings due to 36 candidate standards—new and amended.58 DOE developed “data
sheets” on all 36 standards, populating each with analyses, some of which were taken from
existing rulemakings.59 DOE further reduced this list based on applying a threshold of one quad
of energy savings, made some refinements, and settled on a list of 15 for further consideration.
In a similar exercise, DOE conducted a study of 10 categories of products and equipment when
codifying the standards Congress specified in EISA 2007.60 The study estimated several
quantified benefits and costs—energy savings; consumer and firm cost savings; industry NPV
(INPV); and reductions in emissions. DOE did not use these to assign priorities or a sequence in
which to conduct the rulemakings.61 However, the study is another example of how DOE could
assess the potential energy savings of many standards at once.
Analyzing many standards at a time offers one possible tool for ranking them in the order they
might be addressed in rulemakings. DOE’s 2002 study, for example, did lead to a short-list of
standards DOE might revise first. However, DOE did not implement this strategy as it lacked the
authority to do so.

61 This study considered “the difference between typical baseline product models and product models that comply with
the new EISA 2007 prescribed standard” and “gathered data on shipments or installed equipment stock, baseline
efficiency levels, and typical product usage to determine energy savings benefits of the prescribed standards.” For
purposes of calculating the cumulative energy savings, DOE assumed the existing stock of appliances and equipment
performed at the minimum level of the preexisting federal standards.

DOE's Appliance and Equipment Standards Program: Addressing the Backlog

Another study by the American Council for an Energy Efficient Economy (ACEEE), like DOE’s
EISA 2007-mandated study, started with the current national standards program and projected the
incremental energy savings due to an assumed set of new standards.62 The study made its
projections by reasoning that the energy performance of the new appliances that replace the old
stock would be at the maximum level that is technologically feasible (i.e., “max tech”). This
study and its methods also illustrate one of the challenges in adapting studies of energy efficiency
to the purposes of the national standards program; standards, to be promulgated, must satisfy the
statutory requirement of being economically justified. DOE’s analyses in past rulemakings have
found that the max tech level of performance, while technologically feasible, is not always
economically justified.
Similarly, a 2015 report by DOE considered seven groups of commercial equipment and
estimated the energy savings potential if the current stock were to be replaced with max tech.63
The study measured potential savings, one type of equipment at a time, against a baseline in
which the energy performance of the commercial equipment continued to improve gradually.64
The study was not, however, designed to suggest priorities for regulations nor did it include the
analysis of which of these instances of max tech equipment would have met the EPCA test of
being economically justified. The authors noted that within an end-use category, the results for
individual technologies could not be added together.65 DOE has commissioned similar reports on
single categories (e.g., household furnaces or commercial refrigeration equipment) of products
and equipment and on groups.66
Studying the Energy Efficiency Potential
The second prioritization possibility is the so-called energy efficiency potential. These studies can
include all types of energy-consuming devices, not just those already covered by EPCA, as
amended. In this option, DOE could conduct analyses of the energy savings and other benefits of
revising designated groups of standards, which, as shown in the text box below, might be
comprised of a group of appliances that deliver one type of energy service. Generally speaking,
analyses of efficiency potential take account of interactions between efficiency opportunities.67
For example, such an analysis would consider the fact that appliances in the group may compete
in the marketplace against one another because they can substitute for one another; central air
conditioners might compete with room air conditioners. As discussed earlier, a group of standards
that run concurrently may have a cumulative effect on the consumption of energy commodities
including electricity, natural gas, and so forth. This effect might change the price of energy
commodities, which in turn may affect consumption as consumers and firms react to the new
price—an effect that would be missed in the one-at-a-time approach.

These studies have the common goal of determining what might be the savings in energy if large
numbers of energy-consuming products and equipment were replaced with new ones having
superior energy performance. Such a study may identify gaps in the scope and coverage of the
national standards program.68
A study by the Electric Power Research Institute (EPRI) relied on detailed forecasts of the
number and type of appliances expected to be in use in the future as the old stock of appliances
was replaced.69 The study calculated the extent to which more energy-efficient appliances
replaced the existing stock based on technical feasibility and market and policy factors. The study
reported results by end-use category by census region or division. The study found that results
can vary by region: for the New England Division, the study found the three categories with the
highest achievable potential for energy savings were commercial indoor lighting; residential
computers; and commercial other electronics (i.e., non-computer); for the South Atlantic
Division, the top three were commercial indoor lighting, but followed instead by residential
central air conditioning and commercial central air conditioning.
The method of efficiency potential could, on the one hand, suggest DOE sequence its
rulemakings, conducting those rulemakings for the groups or end-use categories with the highest
efficiency potential first. On the other hand, DOE could choose not to revise the standards having
lowest efficiency potential, were Congress to grant DOE such authority. The efficiency potential
analysis could further reveal that large energy savings were possible for products or equipment
not currently covered in the national standards program. Congress could consider making this a
covered product or require DOE study the possibility of making it a covered product.70 The
Secretary of Energy could also classify a product as “covered” and subject to binding standards
provided certain statutory criteria are met.71
However it is to be calculated, the energy efficiency potential for some groups of appliances—
whether a specific end-use category or other collection—may be greater than for others. DOE
already applies such groupings to the national standards program in the multi-year schedule it
reports to Congress; the text box below lists the groups DOE has used in the past. DOE could
then devote its resources to a basket of rulemakings, analyzing and promulgating standards for
the group or groups of appliances it deems to have the greatest potential to save energy.

68 The one-at-a-time analyses described in the previous section could do so as well—be analyzed in groups; it is not
exclusive to energy efficiency potential studies.

Effect of Prioritizing the Rulemakings
Potential Advantages of Prioritizing Rulemakings
Reduced Number of Rulemakings
One reason given to prioritize rulemakings by applying the criteria discussed in this report is to
realize the benefits of significant conservation of energy as soon as possible. Delaying the
revisions delays the energy savings and other benefits that would accrue with new standards. A
2018 court order focused on the impact of the delay: “DOE’s failure to publish the efficiency
standards for air compressors, commercial packaged boilers, portable air conditioners, and
uninterruptible power supplies harms the Government Plaintiffs [i.e., the states] by delaying the
energy efficiency benefits the Final Rules achieve.”72
A prioritization could address the backlog by reducing the number of still-to-be-completed
rulemakings in Figure 2 by forgoing the revisions that would not meet the prioritization
minimum threshold and allowing more existing resources to be allocated to the remaining
required rulemakings.
Reduced Burden on Industry
Another reason to prioritize rulemakings would be to reduce burdens on industry. In almost all
cases, DOE has estimated its rulemakings to impose additional costs on industry.73 The
rulemaking documents use INPV for this purpose, which is the horizontal axis of Figure 5,
representing the change in the discounted net cash flow accrued by the manufacturers over a 30-
year period.74 In the case of the residential boiler rulemaking, the INPV would on average

2008. The energy savings and other metrics accrue over the lifetime of any products or equipment purchased during the
30 years. See 84 Federal Register 36037 (July 26, 2019).

decrease 0.31%.75 Skipping the rulemaking, on the other hand, would mean the burden on
industry would be essentially zero because DOE would not be imposing any further costs on
manufacturers. At the same time, forgoing the rulemaking would also forgo potential economic
benefits to consumers.

2017
Rulemakings with relatively small energy savings can nonetheless be some of the least costly for industry

Notes: Less than the 0.3 quad threshold = red triangle, greater than or equal to the 0.3 quad threshold = blue
circle. Not shown on the chart are distribution transformers (-4.0% INPV change, 1.9 quads), electric motors
(-0.7% INPV change, 2.8 quads), and air-cooled commercial unitary air conditioners and heat pumps
(CUAC/CUCHP) (-14.6% INPV change, 5.5 quads). These all would have exceeded the 0.3-quad threshold.
Reduced Burden for Some Consumers
A further effect of reducing the number of standards is that some consumers who otherwise
would incur net costs would be spared. DOE has estimated some standards that on average save
consumers money in the purchase of the new appliance, may at the same time incur higher costs
for a small number of consumers.76 In the case of the residential boilers, DOE estimated that,
across all product classes, 2.7% of residential boilers would be more expensive to purchase and
own (i.e., increase the life-cycle costs).77 The life-cycle costs include both the upfront cost and the
costs (or savings) of operating and maintaining the product or equipment—all relative to the

75 81 Federal Register 2393b (January 15, 2016).
76 The calculation of life-cycle costs considers lower fuel costs of the new, more efficient appliance, and any higher
purchase and installation costs.
77 The percentage is shipment-weighted across all product classes. 81 Federal Register 2405 (January 15, 2016).
Congressional Research Service

products or equipment that would be purchased in the absence of a revised standard. Sometimes
the more efficient appliance can be more expensive to purchase but will lead to lower energy
costs, if consumption does not change.78 The promise of lower life cycle costs may not appeal to
all consumers, who may continue to use and repair a less efficient product rather than pay the up-
front cost of the replacement, irrespective of whether the life-cycle cost analysis promises overall
savings.79
Potential Disadvantages of Prioritizing Rulemakings
Reduction in the Estimated Energy Savings
Had DOE applied the 0.3-quad threshold test to rulemakings from 2013 to 2017, it would as
noted have dropped 14 standards rulemakings. Doing so would have foregone 1.625 quads of
energy savings, 8% of the energy savings due to all rulemakings issued during that time period.
Figure 3 shows the amount of energy each of the below-threshold rulemakings was estimated to
save.
Foregoing Consumers’ and Firms’ Cost Savings
The standards can reduce the total cost of ownership to consumers and firms. In other words, the
appliances and equipment that comply with the new standard can accrue savings due to lowered
energy bills, even when taking into account the higher initial cost of the appliance.80 As noted in
this report, some consumers may continue to use and repair a less efficient product instead. The
cost savings is one of the quantities DOE considers when setting the quantitative level of energy
conservation for a particular standard.81
In the counterfactual case provided in this report, culling the 14 standards that did not meet the
0.3-quad threshold would have foregone a total savings of roughly $19 billion, discounted at 3%;
or roughly $8 billion, discounted at 7%. This calculation is an estimate and there are the
following caveats: the 14 standards are being added together despite the fact that they did not run
concurrently; the analysis neglected the impact of the reduced energy consumption on energy
prices; the analysis did not take into account substitution between different appliances or their
collective impact on energy commodities; and the analysis assumes no new standards for 30 years
and makes other assumptions about the future that might be overtaken by events.
Again using the residential boiler example, the DOE analysis estimates that over the lifetime of
all residential boilers that would be sold under the revised standards over a 30-year period,
consumers would save $1.212 billion, discounted at 3% or $0.353 billion, discounted at 7%.
These benefits would have otherwise been foregone had DOE chosen not to complete the
rulemaking.

78 Consumption may change due to the lower cost of electricity or other fuel. The “rebound effect” can occur if the
lower operating cost induces higher demand for the energy service. DOE considers the rebound effect in the case of
furnaces, for example. See Chapter 8 of U.S. Department of Energy, Technical Support Document: Energy Efficiency
Program for Consumer Products and Commercial and Industrial Equipment: Residential Furnaces, Washington, DC,
August 30, 2016, at https://www.regulations.gov/document/EERE-2014-BT-STD-0031-0217.

product consumers would have purchased without a new standard.

positive NPV of customer benefit, and emission reductions) outweigh the burdens (loss of INPV and LCC increases for
some users of these equipment).” 81 Federal Register 1033a (January 8, 2016).

Comparison to Current Approach
The above sections have discussed implementing particular methods to prioritize the rulemakings.
The current approach would, in contrast to such methods, not require the additional resources to
administer the program. Specifically, the current approach would not require the additional
analyses and associated costs such as additional staff who might oversee or execute the analyses.
These associated costs, were they to be incurred, might cause a corresponding decrease in funding
for other programs, implying a shift in priorities.
The current approach also would likely leave unaltered the current speed with which the reviews
are performed. The frequency of revisions, while it might lag the every-six-year requirement,
could reduce conversion costs, relative to one of the above prioritization schemes, as
manufacturers change their product design and manufacturing lines. For example, at least three of
the categories represented in Figure 3, Figure 4, and Figure 5 incurred conversion costs, ranging
from $9.2 million to $184 million per category, in DOE’s estimate.82 Any attempt to bring the
frequency of revisions in line with the every-six-year requirement might lead to more frequent
conversion costs, relative to the current approach.
The current approach, by keeping all standards in play, spreads any potential costs more equally
across manufacturers. A prioritization scheme might favor those categories having greater
potential for energy savings and conduct more frequent revisions to those categories. The costs
might fall disproportionately on a subset of manufacturers whose products had this greater
potential. Maintaining the current approach would avoid the possibility of these more frequent
costs.
Options for Congress
DOE maintains a list of the backlog of energy conservation standards for which it has not begun
the periodic review required by EISA 2007. DOE and Congress have attempted to address the
backlog since the 1990s. Below we describe the status quo and three options for Congress that
could help DOE reduce the backlog.
Left unchanged, the current approach will likely increase the backlog of rulemakings, which
stood at 33 in the last DOE report to Congress.83 The costs to administer the program would not
increase due to any additional analyses needed as part of a prioritization scheme. No categories of
products and equipment would be subject to increased frequency of revisions necessitating more
frequent changes to manufacturing and product design.
First, Congress could consider legislation that addresses the question of what comprises
“significant conservation of energy.” The most straightforward way would be to specify a
minimum quantity or percent of energy saved by the new standard, and only if this minimum
were to be satisfied might DOE proceed with revising a standard. This would reduce the number
of revisions DOE must complete, allowing more existing resources to be allocated to the
remaining upcoming required revisions and to reducing the backlog. The avoided rulemakings
(red triangles in Figure 5, assuming a 0.3 quad threshold) might nonetheless have reduced
consumers’ energy consumption (and thus reduce their energy bills). Further, some of the

rulemakings may have accomplished these savings at very little cost to industry; a group of these
are circled in Figure 5 at the bottom right.
Second, Congress could require DOE to conduct a periodic study of many of the standards. One
study could be the list of standards scheduled for the mandatory six-year review in a given year.
Such a study could determine the expected energy savings of each, individually, and might be
similar in scope to the studies DOE conducted in 2007 to estimate the impacts of the standards
mandated by EISA 2007.84 DOE could use these insights to prioritize groups of standards for
which it estimates the highest conservation of energy. This approach has the advantage over the
one-at-a-time approach (the first option, above) in that it would give the decisionmaker
information on how several years’ worth of rulemakings would provide national energy savings
on a cumulative basis.
Third, Congress could require DOE to prepare a report assessing the energy efficiency potential.
This could cover consumer products and commercial equipment of any type, not just those
currently regulated by DOE and thus might capture additional opportunities for energy savings.
Congress could specify that such studies examine which groups of standards would save the
most. These groups could include heating products, lighting, home appliances, electronics and so
forth.85 DOE could then devote its resources to analyzing and promulgating standards for the
group or groups of appliances it deems to have the greatest energy efficiency potential. The report
could be submitted to Congress as part of the reports already required under EPCA.
Table 1 summarizes the pros and cons of the above three options and also compares them to the
current approach.
