MOST RECENT DEVELOPMENTS
On October 22, 2004, the President signed the American Jobs Creation Act (P.L 108-
357, H.R. 4520). It expands the renewable energy production tax credit (PTC) extended
earlier by P.L. 108-311 to include solar and geothermal over five years and a half-credit over
five years for open-loop biomass, landfill gas, trash combustion, and small hydro used for
irrigation. Further, there is a weight-based credit for refined-coal producers. Also, the law
provides excise and income tax credits for ethanol and biodiesel, enables small ethanol
producers to pass credits to patrons, and creates tax-exempt bonds for green buildings at
brownfields sites.
Omnibus energy legislation has otherwise stalled since mid-June, when the House
passed H.R. 4503 (Energy Policy Act of 2004), which is nearly identical to the conference
version of H.R. 6. Compared to H.R. 4503, the revised Senate omnibus energy bill (S. 2095)
drops the controversial MTBE (methyl tertiary butyl ether) safe harbor provision and cuts the
bill cost to about $15 billion. S. 2095 provides a PTC and other renewables tax provisions
nearly identical to those of H.R. 6 and H.R. 4503. (For a summary of provisions in S. 2095
and H.R. 6, see “Renewables in Omnibus Energy Bills,” below.)
P.L. 108-309 (H.J.Res. 107) provides continuing appropriations through November 20,
2004. The House-passed Energy and Water Development appropriations bill (H.R. 4614)
has $343.2 million for DOE’s Renewable Energy program. (For more details, see “FY2005
DOE Budget” and Table 3.) Also, Section 569(a) of the Senate-passed version of the
Foreign Operations appropriations bill (H.R. 4818, S.Rept. 108-346, p. 146-147) has $180
million for clean (renewable) energy and energy efficiency in developing countries. The
Department of Agriculture (USDA) request, and the House-passed appropriations bill (H.R.
4766), would cut funding for the USDA’s Bioenergy Program and for renewable energy
grants. (See “FY2005 USDA Budget,” below.)
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 website 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
2004, renewable energy resources (excluding wood used for home heating) supplied about
5.8 Q (quadrillion Btu’s or quads) of the 97.7 Q the nation used in 2002, or about 6.0% 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 2004 projects that current policies would yield a 1.9%
average annual increase in renewable energy production to 9.0 Q through 2025, resulting in
a 71% total increase. This would amount to about 6.5% of the projected 136 Q total demand
in 2025. (Detailed breakdowns of renewable energy use appear in EIA’s Renewable Energy
Trends 2003 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 implemented a $42
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 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 FY2005 Congressional Budget Request,
DOE/ME-0034, v. 3, February 2004.)
From FY1973 through FY2003, the federal government spent about $14.6 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 FY2003, it reached $411
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 FY2003, the federal government spent $49.7 billion for
nuclear (fission and fusion), $25.4 billion for fossil, $14.6 billion for renewables, and $11.7
billion for energy efficiency. Total energy R&D spending from FY1948 to FY2003, in 2003
constant dollars, reached $131.2 billion, including $74.0 billion, or 56%, for nuclear; $30.9
billion, or 24%, for fossil; $14.6 billion, or 11%, for renewables; and $11.7 billion, or 9%,
for energy efficiency.
DOE’s FY2004 renewable energy R&D funding totaled $439.4 million, or about 19%
of DOE’s energy R&D appropriation. Energy conservation received $559.7 million (24%),
fossil energy received $672.8 million (29%), and fission and fusion were appropriated $667.4
million (29%).
Tax Credits. The Energy Tax Act of 1978 (P.L. 95-618) created residential solar
credits and 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
CRS-3

IB10041

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). P.L. 106-170 expanded this credit to include poultry waste. Section 603 of the Job
Creation and Worker Assistance Act (P.L. 107-147) extended the production tax credit to
December 31, 2003. Additionally, P.L. 96-223 created an income tax credit for alcohol
fuels; and Section 9003(a)(3) of P.L. 105-178 extended the 40- to 60-cent/gallon credit
through December 31, 2007. Further, the Energy Tax Act created a 5.2 cents/gallon federal
excise tax exemption for gasohol (gasoline blended with alcohol), which now stands at 5.3
cents/gallon.
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.

renewable energy, see Database of Incentives for Renewable Energy [http://www.dsireusa.

Renewables in Omnibus Energy Bills
(S. 1637, S. 2095, and H.R. 6)
In the 108th Congress, most legislative action on renewables has focused on the omnibus
energy policy bills, S. 1637, S. 2095, H.R. 6, and S. 14/S. 1149. Late in 2003, a cloture
motion to stop a filibuster on the conference report (H.Rept. 108-375) for H.R. 6 failed (57-
40). Key objections cited in Senate debate included budget concerns and the Title XV
provisions that would provide a “safe harbor” from product liability lawsuits for producers
of methyl tertiary butyl ether (MTBE), ethanol, and other renewable fuels. The conference
CRS-4

version of H.R. 6 excluded the renewable portfolio standard (RPS) proposed in the Senate
bill, but the production tax credit and the renewable fuel standard (RFS) for cellulosic
ethanol and biodiesel remain in S. 2095. Other renewables provisions in the H.R. 6
conference report include a renewable energy production incentive, a residential solar tax
credit, and other tax and authorization measures. S. 2095 and H.R. 6 also include a provision
(§920) for concentrating solar power R&D that did not appear in either the House or Senate
bill. (For a detailed summary of provisions in the conference version of H.R. 6, see CRS
Report RL32204. For more information about House and Senate bills, see CRS Report
RL32078, which compares House and Senate versions of H.R. 6 with S. 14. For side-by-side
comparisons of provisions in H.R. 6, see CRS Report RL32033 [non-tax provisions], CRS
Report RL32042 [tax provisions], and CRS Report RL32041 [electricity provisions].)
Production Tax Credit (PTC) and Production Incentive (REPI). P.L. 108-311
and P.L. 108-357 extend and expand the PTC. (See “Legislation,” below.)
Parallel to the PTC, there is a renewable energy production “incentive” (REPI) for state
and local governments and nonprofit electrical cooperatives. This 1.5 cent/kwh incentive
was created by EPACT §1212 and is funded by appropriations to DOE. Eligible facilities
currently include solar, wind, biomass, and geothermal energy except municipal solid waste
and certain types of dry steam geothermal energy. S. 2095 (§202) and H.R. 6 (§202) would
make landfill gas eligible too. Also, the eligibility period would be extended for 10 fiscal
years, through 2013; eligibility for payments would be extended through 2023.
Renewable Fuel Standard (RFS). The proposal for a renewable fuel standard (S.
2095, §1501; and H.R. 6, §1501) would be linked with other provisions involving MTBE.
While the H.R. 6 conference report (§1502) would provide a “safe harbor” from product
liability lawsuits for producers of MTBE and other renewable fuels, S. 2095 dropped this
controversial provision.
Under the Clean Air Act Amendments of 1990, reformulated gasoline (RFG) must
contain 2% oxygen, a requirement that led to the use of MTBE, and to a lesser extent
ethanol. However, MTBE has been implicated in numerous incidents of groundwater
contamination, leading 17 states to ban or regulate its use. S. 2095 and H.R. 6 would put a
qualified ban on the use of MTBE as a fuel additive and would replace the RFG requirement
with a renewable fuel standard (RFS), requiring that the annual production of gasoline
contain at least 5 billion gallons of “renewable fuel.”
S. 2095 and H.R. 6 (§1501) define “renewable fuel” to include ethanol, biodiesel, and
natural gas produced from landfills, sewage treatment plants, and certain other sources.
Ethanol is the only renewable motor fuel produced in large quantity. In 2002, about 2.1
billion gallons of ethanol were blended with gasoline. Biodiesel is used at a rate of about 50
million gallons per year. RFS would call for renewable fuels (primarily ethanol) production
to grow to 3.1 billion gallons a year by 2005, and then increase stepwise to 5 billion gallons
a year by 2012. An incentive would encourage the use of cellulosic and waste-derived
ethanol, by raising the value of 1.0 gallon of cellulosic or waste-derived ethanol from a
previous incentive level of 1.5 gallons of renewable fuel up to 2.5 gallons of renewable fuel.

Selected Environmental Provisions in the Energy Bill (H.R. 6).
Renewable Hydrogen. Section 803 of S. 2095 and H.R. 6 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. The
provision includes a focus on distributed energy that uses renewable sources.
Residential Tax Credit. S. 1637 (§823), S. 2095 (§1323) and H.R. 6 (§1323) would
create a 15% residential tax credit worth up to $2,000 for homeowners who purchase
photovoltaics, wind energy, and solar water heating equipment. The credit would be in effect
for three calendar years, ending on December 31, 2006.
Other Non-Tax Provisions. Other renewable energy provisions (and sections)
include resource assessment (201), federal purchases (203), insular areas (204), renewables
in public buildings (205, 922), biomass/biopower (206, 207, 919), geothermal leasing (H.R.
6, 211-227; S. 2095, 211-227), hydropower (231, 241-248), federal lands (352), Indian
energy (503), funding authorizations (918), concentrating solar (920), ocean/wave/marine
(921, 923), net metering (1251), small power (1253), alternative fuels (1503-1514).

FY2005 DOE Budget
The House-passed FY2005 Energy and Water Development appropriations bill (H.R.
4614, H.Rept. 108-554) has $343.2 million for DOE’s Renewable Energy program, which
is $31.6 million, or 8%, less than the request. This reduction includes a cut of $31.0 million
from the Hydrogen program to eliminate hydrogen storage “centers of excellence,” which
the committee states DOE awarded “without full and open competition.” The hydrogen
education initiative would be cut by $7.0 million (zero appropriation) and the National
Climate Change Technology Initiative would be cut by $3.0 million (zero appropriation).
Concentrating Solar Power would increase by $3.4 million.

The FY2005 budget request aims to promote “breakthroughs in hydrogen fuel cells,”
develop advanced technologies for cellulosic biomass as an energy source, and generally
reduce costs while improving the performance and efficiency of various renewable energy
systems. The request also proposes competitive solicitations for applied research on
technologies that would help curb greenhouse gas emissions.
As Table 3 shows, DOE’s FY2005 request seeks $374.8 million for renewables, which
is $4.3 million, or 1%, more than the FY2004 appropriation (including $13.0 million from
prior year balances and excluding inflation). The main increases are for Hydrogen Safety
($12.1 million) and Program Direction ($8.3 million). The main cuts are for Small Modular
Biopower and biomass earmarks (-$13.9 million) and for Concentrating Solar Power (-$3.4
million). Also, the request includes $90.9 million for the Office of Electricity Transmission
and Distribution (OETD), an increase of $10.1 million, mainly for High Temperature
Superconductivity.
FY2005 USDA Budget
For FY2005, the Administration’s request for the Department of Agriculture (USDA)
seeks to reduce the mandatory appropriation for the Bioenergy Program of the Commodity
Credit Corporation (CCC) from $150 million to $100 million. Also, the Administration
proposes to cut renewable energy grants (created by Section 9006 of the Farm Security Act)
from $22.9 million in FY2004 to $10.8 million in FY2005.
On July 13, 2004, the House passed H.R. 4766 (H.Rept. 108-584), the Agriculture,
Rural Development, Food and Drug Administration, and Related Agencies appropriations
bill for FY2005. It has $15.0 million for renewable energy grants (Section 9006). This is
$7.9 million less than the FY2004 appropriation and $4.2 million more than the request.
Section 737 of the bill restricts renewables funds from use for salaries and personnel.
USDA’s 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 2 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 renewable energy equipment
available for loans. Sections 2101 and 6401 of the act provide 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].)

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 CRS Issue Brief IB10006, Electricity: The Road Toward
Restructuring.)
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 108th Congress, the Senate version
of H.R. 6 had an RPS (Sections 264 and 271).
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 website [http://www.eere.energy.gov/greenpower/].)
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. A DOE study, Structural Vulnerability of the North American
Power Grid, suggests that adding more distributed generation could help reduce grid
vulnerability. (More information about DOE’s Distributed Power Program is available at
[http://www.eere.energy.gov/distributedpower/]).

Net Metering. Net metering allows customers with generating facilities to “turn their
electric meters backwards” when feeding power into the grid; 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 kilowatts to 1 megawatt. 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 2003
has created interest in using renewables to dampen natural gas demand. EIA data show that
a growing share of natural gas 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. DOE projects that, by 2020, biomass and energy crops
could produce 15% of natural gas needs.
Substituting Electricity from Renewables for Gas-Fired Generation. Also,
a variety of renewables can generate electricity that indirectly displaces natural gas use for
power generation. The American Wind Energy Association (AWEA) says that the installed
base of wind farms through the end of 2003 will produce enough electric power to reach the
equivalent of 1.1 trillion cubic feet per year in four years. Similarly, with some federal policy
changes, DOE’s report Scenarios for a Clean Energy Future (Table 7.11) projects that
biomass-based power production could be greatly accelerated through 2010. (See the
American Council for an Energy Efficient Economy’s 2003 report, Impacts of Energy
Efficiency and Renewable Energy on Natural Gas Markets and the Union of Concerned
Scientists fact sheet, Renewable Energy Can Help Ease Natural Gas Crunch.)
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 could 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 November 2003 report, U.S. Climate Change
Technology Program — Technology Options for the Near and Long Term, compiles
information from multiple federal agencies on more than 80 technologies. For these end-use
and supply technologies, the report describes President Bush’s initiatives and R&D goals for
advancing technology development, but it does not estimate emissions saving potentials, as
some previous DOE reports on the topic had presented.
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 could play in
curbing global CO emissions.

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. The federal government funds
2
programs for renewable energy as a mitigation measure at DOE, 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.
