U.S. Energy: Overview and Key Statistics
Energy supplies and prices are major economic factors in the United States, and energy markets are volatile and unpredictable. Thus, energy policy has been a recurring issue for Congress since the first major crisis in the 1970s. As an aid in policy making, this report presents a current and historical view of the supply and consumption of various forms of energy.
U.S. Energy: Overview and Key Statistics
This report presents a current and historical view of the supply and consumption of various forms of energy including oil, electricity, coal, and renewable energies. It includes compiled statistics and charts.
The Renewable Fuel Standard (RFS): In Brief
This report provides a basic description of the Renewable Fuel Standard (RFS), which mandates that U.S. transportation fuel must contain a minimum volume of biofuel, and is a federal statutory requirement. The mandated minimum volume increases annually and can be met using both conventional biofuel (e.g., cornstarch ethanol) and advanced biofuels. This report also includes some of the widely-discussed issues.

Energy Policy: Conceptual Framework and Continuing Issues
In the spring of 2006, crude oil prices were exceeding $70/barrel (bbl) in response to tight markets and uncertainty over the security of world oil supply. A number of developments have placed additional pressure on world markets, including Hurricanes Katrina and Rita (in late August and late September 2005), the phaseout of the gasoline additive methyl tertiary butyl ether (MTBE) and a renewable fuels mandate, and a continuing high and worldwide demand for oil. Energy policy issues for continuing interest include opening up the Arctic National Wildlife Refuge (ANWR) for leasing; Corporate Average Fuel Economy Standards (CAFE) for passenger vehicles; improving U.S. energy infrastructure, including pipelines and refineries; seeking effective means to promote energy conservation using currently available technologies, and developing new technologies and alternative fuels.
Energy Efficiency and the Rebound Effect: Does Increasing Efficiency Decrease Demand?
Intuitively it seems obvious to most observers that increasing energy efficiency will ultimately reduce demand for an energy resource such as electricity. Paradoxically, economic theory suggests that this decrease in demand and subsequent decrease in cost of using the resource could cause a rebound in demand. A commonly cited example is an increase in the efficiency of home air conditioning which may reduce the resident’s monetary incentive to conserve. The resident may opt to change the thermostat setting to keep the amount he pays constant, but living at a more comfortable temperature. When actually measured this “Rebound Effect” is generally acknowledged to lower predicted reductions in electricity demand by 10%-40% depending on the device that is made more efficient.
Energy and the 97th Congress: Overview
During his campaign, President Reagan called for a major shift in this country's energy policy. In particular, the President emphasized the need for more domestic production of energy and reliance on market forces to produce and distribute energy products. Now in office, the new Administration is employing executive, administrative, and legislative methods to implement these changes.

Energy Costs and Agriculture
U.S. agriculture is not an especially energy-intensive industry, but energy does account for about 6% of farm production costs. Additionally, farming is a highly mechanized industry and requires timely energy supplies at particular stages of the production cycle in order to achieve optimum yields. A substantial part of energy use by agriculture is indirect —embodied in the chemicals applied and machinery used on farms.
Algae's Potential as a Transportation Biofuel
This report discusses the status of algae-based biofuels (ABB) research and development, federal funding, and legislative concerns.
Biofuels Incentives: A Summary of Federal Programs
This report outlines federal programs that provide direct or indirect incentives for biofuels. For each program described, the report provides details including administering agency, authorizing statute(s), annual funding, and expiration date.
Energy: Selected Facts and Numbers
This report discusses the energy policy that has been a recurring issue for Congress since the first major crisis in the 1970s. The report offers a general view of energy consumption trends, and Table 1 shows consumption by economic sector — residential, commercial, transportation, and industry — from 1950 to the present.
Gasoline and Oil Prices
This report examines the extent of price increases in gasoline and oil, focuses on the linkage between the two, and analyzes the causes of the price increases, and the likelihood that they might be reversed through market responses, or policy measures.
DOD Alternative Fuels: Policy, Initiatives and Legislative Activity
This report provides background information and identifies issues for Congress regarding Department of Defense (DOD) alternative fuel initiatives, a subject of debate at congressional hearings on DOD's proposed FY2013 budget. The services (the Army, Navy, and Air Force) have spent approximately $48 million to purchase alternative fuels, and the Navy has proposed a $170 million investment in biofuel production capacity. The services have also spent funds on testing, certification and demonstrations of alternative fuels. By comparison, DOD purchases of petroleum fuels totaled approximately $17.3 billion in FY2011.
Cellulosic Biofuels: Analysis of Policy Issues for Congress
This report discusses Cellulosic biofuels, which are produced from cellulose derived from renewable biomass. They are thought by many to hold the key to increased benefits from renewable biofuels because they are made from low-cost, diverse, non-food feedstocks, and could also potentially decrease the fossil energy required to produce ethanol, resulting in lower greenhouse gas emissions.
Energy Efficiency: Budget, Oil Conservation, and Electricity Conservation Issues
This report discusses various budget issues regarding the Department of Energy's Energy Efficiency Program, which is conducted by the Office of Energy Efficiency and Renewable Energy (EERE).
Gasoline Prices: New Legislation and Proposals
This report discusses policy options for Congress regarding gas prices. The high price of gasoline was an important consideration during the debate on major energy legislation, which ended with the Energy Policy Act of 2005, H.R. 6 (P.L. 109-58). However, prices continued to surge, due to a large number of factors, such as the effects of Hurricane Katrina on Gulf Coast refineries, an increased world demand for crude oil, and inadequate U.S. refinery capacity.
Biomass: Comparison of Definitions in Legislation
This report discusses the use of biomass, its legislative history, and the proposed redefinition of biomass in legislation.
Energy Policy: The Continuing Debate and Omnibus Energy Legislation
This report discusses a variety of issues pertaining to energy policy. It includes information about most recent developments, background and analysis broken down into major categories, and relevant legislation.
Energy Policy: Setting the Stage for the Current Debate
This report discusses the energy policy. Comprehensive energy legislation was introduced in the Senate by both parties by late March (S. 388, S. 389, S. 596, S. 597).
Solar Projects: DOE Section 1705 Loan Guarantees
This report discusses the solar energy initiative and the political implications. The objective of this report is to provide Congress with insight regarding solar projects supported by Department of Energy (DOE’s) loan guarantee program, the risk characteristics of these projects, and how other DOE loan guarantee projects are either similar to or different from the Solyndra solar manufacturing project.
Energy Provisions in the 2014 Farm Bill (P.L. 113-79)
This report focuses on the policies contained in the 2014 farm bill that support agriculture based renewable energy, especially biofuels. The introductory sections of this report briefly describe how U.S. Department of Agriculture (USDA) bioenergy policies evolved and how they fit into the larger context of U.S. biofuels policy.
