Advanced Energy Technologies: Key Challenges to Their Development and Deployment
GAO-07-550T: Published: Feb 28, 2007. Publicly Released: Feb 28, 2007.
For decades, the nation has benefited from relatively inexpensive energy, but it has also grown reliant on fossil fuels--oil, natural gas, and coal. Periodic imported oil supply disruptions have led to price shocks, yet the nation's dependence on imported energy is greater than ever. Fossil fuel emissions of carbon dioxide--linked to global warming--have also raised environmental concerns. The Dep...
Department of Energy: Key Challenges Remain for Developing and Deploying Advanced Energy Technologies to Meet Future Needs
GAO-07-106: Published: Dec 20, 2006. Publicly Released: Jan 19, 2007.
Despite periodic price shocks and related energy crises, the United States is even more dependent on crude oil and natural gas than it was almost 30 years ago. And, without dramatic change, the nation will become ever more reliant on imported oil and natural gas with attendant threats to national security. The nation has also become concerned about global warming, which has been linked to carbon d...
Strategic Petroleum Reserve: Available Oil Can Provide Significant Benefits, but Many Factors Should Influence Future Decisions about Fill, Use, and Expansion
GAO-06-872: Published: Aug 24, 2006. Publicly Released: Oct 3, 2006.
Congress authorized the Strategic Petroleum Reserve (SPR), operated by the Department of Energy (DOE), to release oil to the market during supply disruptions and protect the U.S. economy from damage. The reserve can store up to 727 million barrels of crude oil, and currently contains enough oil to offset 59 days of U.S. oil imports. GAO answered the following questions: (1) What factors do experts...
Meeting Energy Demand in the 21st Century: Many Challenges and Key Questions
GAO-05-414T: Published: Mar 16, 2005. Publicly Released: Mar 16, 2005.
Plentiful, relatively inexpensive energy has been the backbone of much of modern America's economic prosperity and the activities that essentially define our way of life. The energy systems that have made this possible, however, are showing increasing signs of strain and instability, and the consequences of our energy choices on the natural environment are becoming more apparent. The reliable ener...
Oil and Gas Development: Challenges to Agency Decisions and Opportunities for BLM to Standardize Data Collection
GAO-05-124: Published: Nov 30, 2004. Publicly Released: Jan 3, 2005.
U.S. consumption of oil and natural gas increasingly outpaces domestic production, a gap that is expected to grow rapidly over the next 20 years. There has been increasing concern about U.S. reliance on foreign energy sources. One option being considered is to increase domestic production of resources on land under the jurisdiction of the Department of the Interior's Bureau of Land Management (BLM...
Federal Energy Management: Facility and Vehicle Energy Efficiency Issues
GAO-03-545T: Published: Mar 12, 2003. Publicly Released: Mar 12, 2003.
GAO testified that constructing and operating buildings requires enormous amounts of energy, water, and materials and creates large amounts of waste. How agencies manage their facilities, along with the vehicles they use to accomplish their missions, has significant cost implications and greatly affects the environment. According to the Department of Energy, energy management is one of the most ch...
Research and Development: Lessons Learned from Previous Research Could Benefit FreedomCAR Initiative
GAO-02-810T: Published: Jun 6, 2002. Publicly Released: Jun 6, 2002.
The federal government has spent billions of dollars attempting to reduce the consumption of petroleum in the transportation sector for over 25 years. Throughout the period, the government has tried tax incentives, mandates to use vehicles that run on alternative fuels, and laws designed to enhance fuel efficiency. More recently, the federal government conducted a $1.2 billion partnership between...
U.S. Ethanol Market: MTBE Ban in California
GAO-02-440R: Published: Feb 27, 2002. Publicly Released: Mar 5, 2002.
The 1990 amendments to the Clean Air Act require that an additive be added to gasoline in areas with excessive carbon monoxide or ozone pollution. Specifically, those areas with "severe" ozone pollution are required to use reformulated gasoline, which contains at least two percent oxygen by weight. In California, as in other areas of the country, oil refining companies primarily use the oxygenate...
Alternative Motor Fuels and Vehicles: Impact on the Transportation Sector
GAO-01-957T: Published: Jul 10, 2001. Publicly Released: Jul 10, 2001.
The transportation sector accounts for roughly two thirds of the nation's petroleum consumption and one quarter of the total U.S. energy use. Several steps have been taken during the last 25 years either to reduce petroleum consumption or to increase fuel diversity in the transportation sector, including tax incentives, mandates for alternative fuel vehicles, and laws to promote automobile fuel ef...
California Electricity Market Options for 2001: Military Generation and Private Backup Possibilities
GAO-01-865R: Published: Jun 27, 2001. Publicly Released: Jun 29, 2001.
Since May 2000, California's restructured electricity market has experienced rapidly rising prices and uncertain reliability. In response to disruptions in service, or blackouts, the state has taken steps to increase electricity supplies and to reduce demand through conservation. The California Independent System Operator, the agency in charge of balancing electricity supply with demand, expects h...
