MOST RECENT DEVELOPMENTS
Senate floor action on the omnibus energy bill (S. 14) is expected to resume in mid-July.
Debate is expected to focus on floor amendments that would add a renewable energy
portfolio standard (RPS) and a renewable fuel standard (RFS). Also, the energy tax bill, S.
1149, is expected to come up as a floor amendment. It expands the renewable energy
production tax credit, creates incentives for alternative fuels, and creates a residential tax
credit for solar and geothermal equipment. Action was suspended on June 12, 2003, after
about 350 amendments were proposed, including 40 on renewable energy. (For a
comparison of the House and Senate provisions, see “Renewables in Omnibus Energy Bills,
108th Congress,” hereafter.)
In late April 2003, the House Appropriations Committee issued updated appropriation
figures for FY2003. On February 3, 2003, the Bush Administration issued its FY2004
budget request. For the Renewable Energy Program under DOE’s Office of Energy
Efficiency and Renewable Energy (EERE), it seeks $444.2 million (excluding funding for
retirements), which is $27.7 million more than the FY2003 appropriation, not including
inflation. It includes $49.4 million more for Hydrogen Technology (as part of the President’s
Hydrogen Fuel Initiative) and $15.0 million more for a National Climate Change Technology
Initiative. It would also would terminate the Concentrating Solar Power Program and cut
Biomass/Biorefinery Programs by $17.0 million. The request presents a new budget
structure that follows from a major reorganization of the EERE Office.

gov/budget/04budget/content/es/solar.pdf].)
BACKGROUND AND ANALYSIS
Renewable Energy Concept
Renewable energy is derived from resources that are generally not depleted by human
use, such as the sun, wind, and water movement. These primary sources of energy can be
converted into heat, electricity and mechanical energy in several ways. There are some
mature technologies for conversion of renewable energy such as hydropower, biomass, and
waste combustion. Other conversion technologies, such as wind turbines and photovoltaics,
are already well-developed, but have not achieved the technological efficiency and market
penetration which many expect they will ultimately reach. Although geothermal energy is
produced from geological rather than solar sources, it is often included as a renewable energy
resource and this brief treats it as one. Commercial nuclear power is not generally
considered to be a renewable energy resource. (For further definitions of renewable energy,
see the National Renewable Energy Laboratory’s web site information on “Clean Energy
101” at [http://www.nrel.gov/clean_energy/].)

Contribution to National Energy Supply
According to the Energy Information Administration’s (EIA’s) Annual Energy Outlook
2003, renewable energy resources (excluding wood use for home heating) supplied about 5.3
Q (quadrillion Btu’s or quads) of the 97.3 Q the nation used in 2001, or about 5.4% of
national energy demand. More than half of renewable energy production takes the form of
electricity supply. Of this, most is provided by large hydropower. However, from 1998
through 2001, a drought-driven decline in hydroelectric availability led to a major drop in
national renewable energy use. Industrial use of renewables, supplied primarily by biofuels,
accounts for most of the remaining contribution.
After more than 25 years of federal support, some note that renewable energy has
achieved neither a high level of market penetration nor a growing market share among other
energy sources. A recent review of renewable energy studies by Resources for the Future,
Renewable Energy: Winner, Loser, or Innocent Victim?, concludes that the lower-than-
projected market penetration and flat market share are due primarily to declining fossil fuel
and electricity prices during this period. In contrast, however, it notes that the costs for
renewable energy technologies have declined by amounts equal to or exceeding those of
earlier projections.
EIA’s Annual Energy Outlook 2003 projects that current policies would yield a 2.1%
average annual increase in renewable energy production to 8.8 Q through 2025, resulting in
a 65% total increase. This would amount to about 6.3% of the projected 139 Q total demand
in 2025. (Detailed breakdowns of renewable energy use appear in EIA’s Renewable Energy
Annual 2001
and Renewable Energy 2000: Issues and Trends.)
Role in Long-Term Energy Supply
Our Common Future, the 1987 report of the United Nations’ World Commission on
Environment and Development, found that “energy efficiency can only buy time for the
world to develop ‘low-energy paths’ based on renewable sources.” Though many renewable
energy systems are in a relatively early stage of development, they offer “a potentially huge
primary energy source, sustainable in perpetuity and available in various forms to every
nation on Earth.” The report suggested that a Research, Development, and Demonstration
(RD&D) program of renewable energy projects is required to attain the level of primary
energy now obtained from a mix of fossil, nuclear, and renewable energy resources.
The Agenda 21 adopted at the 1992 United Nations Conference on Environment and
Development (UNCED) concluded that mitigating urban air pollution and the adverse impact
of energy use on the atmosphere — such as acid rain and climate change — requires an
emphasis on “clean and renewable energy sources.” The U.N. Commission on Sustainable
Development oversees implementation of Agenda 21. The 2002 U.N. World Summit on
Sustainable Development (Johannesburg Summit) adopted a Political Declaration and a
Plan of Implementation ([http://www.johannesburgsummit.org/]), which includes “Clean
Energy” as one of five key policy actions. The U.S. Department of State plans to implement
a $43 million Clean Energy Initiative in 2003 ([http://www.state.gov/g/oes/sus/wssd/]), and
the European Union committed to a $700 million energy partnership.

History
The oil embargo of 1973 sparked a quadrupling of energy prices, major economic
shock, and the establishment of a comprehensive federal energy program to help with the
nation’s immediate and long-term energy needs. During the 1970s, the federal renewable
energy program grew rapidly to include basic and applied R&D, and joint federal
participation with the private sector in demonstration projects, commercialization, and
information dissemination. In addition, the federal government instituted market incentives,
such as business and residential tax credits, and created a utility market for non-utility
produced electric power through the Public Utility Regulatory Policies Act (P.L. 95-617).
The subsequent failure of the oil cartel and the return of low oil and gas prices in the
early 1980s slowed the federal program. Despite Congress’s consistent support for a broader,
more aggressive renewable energy program than any Administration, federal spending for
these programs fell steadily through 1990. Until 1994, Congress led policy development and
funding through legislative initiatives and close reviews of annual budget submissions.
FY1995 marked a noteworthy shift, with the 103rd Congress for the first time approving less
funding than the Administration had requested. The 104th Congress approved 23% less than
the Clinton Administration request for FY1996 and 8% less for FY1997. However, funding
turned upward again during the 105th Congress and in the 106th Congress. (A detailed
description of DOE programs appears in DOE’s FY2003 Congressional Budget Request,
DOE/ME-0003, v. 3, February 2002.)
From FY1973 through FY2002, the federal government spent about $14.2 billion (in
2003 constant dollars) for renewable energy R&D. Renewable energy R&D funding grew
from less than $1 million per year in the early 1970s to over $1.4 billion in FY1979 and
FY1980, then declined steadily to $148 million in FY1990. By FY2002, it reached $403
million in 2003 constant dollars.
This spending history can be viewed within the context of DOE spending for the three
major energy supply R&D programs: nuclear, fossil, and energy efficiency R&D. From
FY1948 through FY1972, in 2003 constant dollars, the federal government spent about $24.3
billion for nuclear (fission and fusion) energy R&D and about $5.5 billion for fossil energy
R&D. From FY1973 through FY2002, the federal government spent $49.1 billion for
nuclear (fission and fusion), $24.8 billion for fossil, $14.2 billion for renewables, and $11.1
billion for energy efficiency. Total energy R&D spending from FY1948-FY2002, in 2003
constant dollars, reached $128.9 billion, including $73.4 billion, or 57%, for nuclear, $30.2
billion, or 23%, for fossil, $14.2 billion, or 11%, for renewables, and $11.1 billion, or 9%,
for energy efficiency.
Tax Credits. The Energy Tax Act of 1978 (P.L. 95-618) created residential solar
credits and the residential and business credits for wind energy installations; it expired on
December 31, 1985. However, business investment credits were extended repeatedly
through the 1980s. Section 1916 of the Energy Policy Act of 1992 (EPACT, P.L. 102-486)
extended the 10% business tax credits for solar and geothermal equipment indefinitely. Also,
EPACT Section 1914 created an income tax “production” credit of 1.5 cents/kwh for
electricity produced by wind and closed-loop biomass (energy crops or trees grown only for
use as a fuel) systems. P.L. 106-170 expanded this credit to include poultry waste. On
March 9, 2002, the Job Creation and Worker Assistance Act of 2002 (P.L. 107-147, H.R.
CRS-3

IB10041
06-27-03
3090) was signed into law. Section 603 extends the production tax credit for wind, closed-
loop biomass, and poultry waste, retrospectively, from December 31, 2001 to December 31,
2003.
Public Utility Regulatory Policies Act. The Public Utilities Regulatory Policies
Act (PURPA, P.L. 96-917) required electric utilities to purchase power produced by qualified
renewable power facilities. Under PURPA, the Federal Energy Regulatory Commission
(FERC) established rules requiring that electric utilities purchase power from windfarms and
other small power producers at an “avoided cost” price based on energy and capacity costs
that the utility would otherwise incur by generating the power itself or purchasing it
elsewhere. However, to receive avoided cost payments, each renewables facility must file
for, and obtain, qualifying facility (QF) status from FERC. EIA’s Renewable Energy 2000:
Issues
reports that, in 1998, QF renewable power capacity reached 12,700 megawatts (MW)
and generation reached 64 billion kilowatt-hours (kwh). Thus, QFs provided about 1.6% of
national electric capacity and about 1.7% of national electricity generation. In comparison,
the capacity of all renewables reached 94,800 MW, or about 12% of national capacity; and
generation for all renewables stood at 418,000, which is about 11.5% of national generation.
State and Local Government Roles. State and local governments have played a
key role in renewable energy development. For example, in the early 1980s, a generous state
investment tax for wind energy in California combined with PURPA and the federal tax
credit to stimulate industry development of the first windfarms. California and New York
have invested some state funds in renewable energy R&D. Recently, Texas and several other
states have used a regulatory tool, the renewable energy portfolio standard (RPS), to
encourage renewable energy. Also, in 2001, the City of San Francisco enacted a $100
million revenue bond (Proposition B, “Vote Solar”) to support solar and wind energy
implementation.

energy, see Database of Incentives for Renewable Energy [http://www.dsireusa.org/].)
DOE’s Office of Energy Efficiency and Renewable Energy (EERE). This
office is led by the Assistant Secretary for Energy Efficiency and Renewable Energy. In
2002, Assistant Secretary David Garman completed a major reorganization of EERE. The
new management strategy is described in Focused on Results: A New Government Business
Model
, available at [http://www.eere.energy.gov/office_eere/pdfs/eere_reorg.pdf]. More
information about EERE is available on the DOE web site [http://www.eere.energy.gov/
office_eere/organization.html].
Renewables in Omnibus Energy Bills, 108th Congress
In the 108th Congress, most legislative action on renewables has focused on the omnibus
energy policy bills, H.R. 6 and S. 14, the renewable fuel standard bills (S. 385 and S. 791)
and the Senate energy tax bill, S. 1149 (replaces S. 597), which is expected to be added to
S. 14 in floor action. On April 10, 2003, the House passed the omnibus energy bill (H.R. 6).
It has a renewable energy production tax credit (PTC), renewable energy production
incentive (REPI), renewable fuel standard (RFS), the residential solar and geothermal tax
credit, and certain alternative fuels incentives. The Senate bill (S. 14 and S. 1149) has
CRS-4

IB10041

similar provisions, but with some differences. Also, one renewable energy floor amendment
(H.Amdt. 72) was adopted, which would authorize funds for the General Services
Administration (GSA) to install solar electric equipment in public buildings. Other
renewables provisions cover hydroelectric relicensing, geothermal leasing, biomass grants,
and authorizations for renewable energy R&D programs. (For information on H.R. 4, the
omnibus energy bill in the 107th Congress, see CRS Report RL31427.)
Renewable Portfolio Standard (RPS). In the 107th Congress, a 10% RPS
provision was adopted (58-42) into the Senate version of H.R. 4, the omnibus energy bill.
In the 108th Congress, an attempt was made in the House Committee on Energy and
Commerce to amend H.R. 6 with an RPS provision, but it was rejected. In the Senate
Committee on Energy and Natural Resources, an amendment to add a 10% RPS was defeated
(11-12). Thus, as reported by Committee, the Senate omnibus energy bill does not include
an RPS provision. However, one floor amendment is expected that would add a 20% RPS,
similar to the one proposed in S. 944 (Section 3). Another draft floor amendment would add
a 10% RPS, similar to the provision proposed in Committee. This draft amendment draws
from the provision that was adopted in the Senate version of H.R. 4 in the 107th Congress.
However, the new provision is different. It is much simpler and less prescriptive, leaving key
decisions about its structure and leaves determination of its relationship to state measures up
to the discretion of the DOE Secretary. Aside from the choice of the percentage target, the
anticipated RPS amendment must address concerns about the eligibility of municipal solid
waste energy resources and the conditions under which municipal power agencies and rural
electric cooperatives may be qualified for tradeable credits. A CRS memorandum on RPS
is available at [http://www.congress.gov/brbk/pdf/ebele27.pdf].
Production Tax Credit (PTC) and Production Incentive. The existing
renewable energy production tax credit provides a 1.8 cents/kwh credit for businesses that
generate power from wind, closed-loop biomass (energy crops), and poultry waste for sale
to the grid. P.L. 107-147 extended this credit through Dec. 31, 2003. Both H.R. 6 (Section
41002) and S. 1149 would extend the credit for three years, through Dec. 31, 2006. They
would also expand the eligible sources to include open-loop biomass (forest, agricultural, and
construction wastes). H.R. 6 would further extend the credit to landfill gas and trash
combustion facilities. S. 1149 does not include landfill gas and trash facilities, but would
expand credit eligibility to swine and bovine waste, geothermal energy, solar energy, small
irrigation power facilities, municipal biosolids, and recycled sludge. Further, S. 1149
(Section 104) sets conditions under which the credit could be transferable.
Parallel to the PTC, there is a renewable energy production “incentive” (REPI) for state
and local governments. This 1.5 cent/kwh incentive was created by EPACT Section 1212
and it is funded through appropriations to DOE. H.R. 6 (Section 16072) and S. 14 (Section
502) have identical provisions that would extend this incentive through 2023 and add landfill
gas to the list of eligible resources.
Renewable Energy Fuel Standard (RFS). According to the Renewable Fuels
Association, the ethanol industry produced 2.2 billion gallons in 2002. H.R. 6 (Section
17101) sets a target for blending gasoline with renewable fuels, including ethanol and
biodiesel. The RFS would start in 2005 at 2.7 billion gallons per year and grow to 5.0 billion
gallons per year in 2015. Also, it extends exemption from product liability claims (safe
harbor) to methyl tertiary-butyl ether (MTBE) producers. In Senate floor action on June 5,
CRS-5

IB10041
06-27-03
2003, the approval (67-29) of S.Amdt 850 to S. 14 added an RFS provision that sets a 5.0
billion gallon target for 2012. Further, it bans use of MTBE. Also, S.Amdt. 854 was
approved (voice vote) as a second-degree amendment to S.Amdt. 850. It encourages the use
of cellulosic ethanol to attain the target by raising the value of 1.0 gallon of cellulosic ethanol
from a previous level of 1.5 gallons of renewable fuel to 2.5 gallons. Several amendments
(nos. 843, 844, 851, 853) to allow waivers or exemptions from the RFS were defeated.
Renewable Hydrogen. H.R. 6 (Section 60003) would create a program to produce
hydrogen from a variety of sources, including renewable energy and renewable fuels, as part
of a broader effort to develop hydrogen fuels, vehicles, and infrastructure. Some hydrogen
provisions of S. 14 (Sections 801-825) include references (e.g. Section 802) to renewables.
Residential Tax Credit. H.R. 6 (Section 41001) and S. 1149 (Section 303) would
create a 15% residential tax credit worth up to $2,000 for homeowners who purchase
photovoltaics and solar water heating equipment. The Solar Energy Industry Association
says the credit would be more effective with a $4,000 cap and shorter eligibility period. The
Senate version also provides a 30% credit worth up to $1,000 for wind energy equipment.
Alternative Fuels Incentives. In H.R. 6, Sections 15011-15024, 15046, 17102-
17108, and 21703 have measures related to alternative fuels and vehicles. In S. 1149,
Sections 201-209 contain incentives for ethanol, biodiesel, and other alternative fuels.
Other renewable energy provisions are identified in Table 1, below.

FY2004 DOE Budget
The FY2004 request for DOE finds that hydrogen energy is the “most promising long-
term revolution in energy use that can help the nation “liberate itself from dependence on
imported oil,” according to the Budget of the U.S. Government FY2004 (p 105). The
FY2004 request for DOE’s Renewable Energy Program elaborates that its aim is to
“accelerate progress” and make hydrogen technologies “cleaner, safer, and lower in cost.”
Further, it stresses that the new National Climate Change Technology Initiative will create
“competitive solicitations” in applied research that aims to reduce greenhouse gas emission
and will “complement” existing R&D programs.
FY2003 USDA Budget
In the 108th Congress, debate has surfaced over appropriations for executing the
mandatory spending requirements for renewable energy and energy efficiency programs, set
by Title IX (Section 9006) of the Farm Security and Rural Investment Act of 2002.
The Department of Agriculture’s (USDA) renewable energy programs have recently
grown, spurred by federal bioenergy initiatives (P.L. 106-224, Executive Order 13134), the
President’s National Energy Policy, and the Farm Security Act (P.L. 107-171). According
to USDA, renewable energy program funding reached $247.6 million in FY2002. Table 3
shows some funding details. Also, for FY2003, Section 6013 of the Farm Security Act of
2002 provides loan guarantees for renewable energy equipment and broadens the range of

other programs and incentives for renewable energy (For more information about USDA
Bioenergy Programs, go to the website at [http://www.ars.usda.gov/bbcc/index.htm]).
Electricity from Renewable Energy
The Public Utility Regulatory Policies Act (PURPA) has been key to the growth of
electric power production from renewable energy facilities. Since 1994, state actions to
restructure the electric utility industry have dampened PURPA’s effect. H.R. 6 (Section
16062) and S. 14 (Section 1145) include a conditional repeal of the mandatory renewables
purchase requirement in Section 210 of PURPA. (For a discussion of broader electricity
restructuring issues, see the CRS Electronic Briefing Book on Electricity Restructuring at
[http://www.congress.gov/brbk/html/ebele1.shtml].)
Renewables Under Electric Industry Restructuring. To encourage a continued
role for renewable energy under restructuring, some states and utilities have enacted such
measures as a renewable energy portfolio standard (RPS), public benefits fund (PBF), and/or
“green” pricing and marketing of renewable power. In the 107th Congress, the Senate version
of H.R. 4 had an RPS (see above under "Renewable Energy Portfolio Standard").

Green Power. The term “green power” generally refers to electricity supplied in
whole or in part from renewable energy sources. Green power marketing (retail or
wholesale) is underway in California, Illinois, Massachusetts, New Jersey, New York,
Pennsylvania, and Texas. Green pricing is an optional utility service that allows electricity
customers who are willing to pay a premium for the environmental benefits of renewable
energy to purchase green power instead of conventional power. Utility green pricing
programs reach more than one-third of the nation’s consumers. (For more on green power
see the web site [http://www.eren.doe.gov/greenpower/home.shtml].)
Distributed Generation. Distributed generation involves the use of small, modular
electricity generators sited close to the customer load that can enable utilities to defer or
eliminate costly investments in transmission and distribution system upgrades, and provide
customers with quality, reliable energy supplies that may have less environmental impact
than traditional fossil fuel generators. Technologies for distributed electricity generation use
wind, solar, bioenergy, fuel cells, gas microturbines, hydrogen, combined heat and power,
and hybrid power systems. (More information about DOE’s Distributed Power Program is
available at [http://www.eren.doe.gov/distributedpower/]).
Net Metering. Net metering allows customers with generating facilities to “turn their
electric meters backwards” when they are feeding power into the grid, so that they receive
retail prices for the excess electricity they generate. This encourages customer investment
in distributed generation, which includes renewable energy equipment. In 2002, California
enacted laws (AB58, Chapter 836; AB2228, Chapter 845) that encourage net metering,
including a provision that permanently raises the size limit from 10 kw to 1 Mw. Also, H.R.
6 (Section 16071) and S. 14 (Section 1141) provide nearly identical language for net
metering.
Natural Gas and Renewables
Biomass-Generated Synthetic Natural Gas. The natural gas price spike in
spring 2003 has created interest in using renewables to dampen natural gas demand. EIA
data presented at a June 10 hearing of the House Energy and Commerce Committee show
not only that natural gas is used for heating, but that a growing share is used for electric
power generation. Renewable energy (mainly biomass) can be used to produce methane (the
main component of natural gas) to substitute for natural gas directly. Also, a variety of
renewables can generate electricity that indirectly displaces natural gas use for power
generation. In 2002, the nation used about 20 trillion cubic feet (Tcf) of natural gas. DOE
says biomass currently produces about 110 billion cubic feet of methane, mostly in the form
of biogas (LFG, 55% methane) from landfills. More than half is used for direct heat and the
remainder for power that is sold to the grid. There are 1,100 MW of LFG power facilities
in place. For its methane outreach programs, EPA reports about 400 MW of proposed
projects that could be accelerated in the short term. Further, DOE projects that over a five-
year period biomass resources (mainly urban residues and mill residues) could produce over
1 tcf per year of synthetic natural gas. Incorporating energy crops could allow the annual
production to reach 3 to 5 Tcf by 2020.
Substituting Electricity from Renewables for Gas-Fired Generation. The
American Wind Energy Association (AWEA) says that the installed base of wind farms,
CRS-9

IB10041
06-27-03
including those that will be installed by the end of 2003, will produce enough electric power
to save 0.18 trillion cubic feet (Tcf) of natural gas that would otherwise be used for power
generation in 2004. Assuming the current gas shortfall is about 1.5 Tcf, AWEA concludes
that wind power lessens the shortfall by 10% to 15%. To help with an ongoing natural gas
problem, AWEA further projects that over the next four years accelerated wind power
production could reach the equivalent of 1.1 Tcf per year. That rapid increase assumes
significant enhancements of power transmission capacity in the Midwest and West.
Similarly DOE’s report Scenarios for a Clean Energy Future (Table 7.11) projects that
biomass-based power production could be greatly accelerated through 2010. This
acceleration assumes the PTC is extended, R&D spending is enhanced, national RPS is
enacted, and other policy changes.
Climate Change and Renewables
Because most forms of renewable energy generate no carbon dioxide (CO ), renewables
2
are seen as a key long-term resource that can substitute for fossil energy sources used to
produce vehicle fuels and electricity. The percentage of renewable energy substitution
depends on technology cost, market penetration, and the use of energy efficiency measures
to control energy prices and demand. DOE’s 2000 report, Scenarios for a Clean Energy
Future
, estimates that new policies could triple non-hydro renewables electricity production
in 2010 from a projected business-as-usual 86 billion kilowatt-hours (Bkwh) to 265 Bkwh.
EPA’s Climate Action Report-2002 describes federal renewable energy programs aimed at
reducing greenhouse gas emissions. In Climate Change 2001: Mitigation, the
Intergovernmental Panel on Climate Change looks at the role that renewables can play in
curbing global CO emissions.
2
Since 1988, the federal government has accelerated programs that study the science of
global climate change and has initiated programs aimed at mitigating fossil fuel-generated
carbon dioxide (CO ) and other human-generated emissions.
2
The federal government funds programs for renewable energy as a mitigation measure
at DOE, the Department of Agriculture (USDA), the Environmental Protection Agency
(EPA), the Agency for International Development (AID), and the World Bank. The latter
two agencies have received funding for renewable energy-related climate actions through
Foreign Operations appropriations bills.
Because CO contributes the largest share of greenhouse gas emission impact, it has
2
been the focus of studies of the potential for reducing emissions through renewable energy
and other means. Except for biofuels and biopower, wherever renewable energy equipment
displaces fossil fuel use, it will also reduce carbon dioxide (CO ) emissions, as well as
2
pollutants that contribute to water pollution, acid rain, and urban smog. In general, the
combustion of biomass for fuel and power production releases CO at an intensity that may
2
rival or exceed that for natural gas. However, the growth of biomass material, which absorbs
CO , offsets this release. Hence, net emissions occur only when combustion is based on
2
deforestation. In a “closed loop” system, biomass combustion is based on rotating energy
crops, there is no net release, and its displacement of any fossil fuel, including natural gas,
reduces CO emissions.
