Federal Energy Management: Addressing Challenges through Better Plans and Clarifying the Greenhouse Gas Emission Measure Will Help Meet Long-term Goals for Buildings
GAO-08-977: Published: Sep 30, 2008. Publicly Released: Sep 30, 2008.
The federal government is the nation's single largest energy consumer, spending approximately $17 billion in fiscal year 2007. A number of statutes and executive orders have established and revised goals directing agencies to reduce energy consumption and greenhouse gas emissions--such as carbon dioxide, which results from combustion of fossil fuels and natural processes, among other things--and i...
Architect of the Capitol: Progress in Improving Energy Efficiency and Options for Decreasing Greenhouse Gas Emissions
GAO-08-917T: Published: Jun 18, 2008. Publicly Released: Jun 18, 2008.
In April 2007, GAO reported that 96 percent of the greenhouse gas emissions from the Capitol Hill Complex facilities--managed by the Architect of the Capitol (AOC)--resulted from electricity use throughout the complex and combustion of fossil fuels in the Capitol Power Plant. The report concluded that AOC and other legislative branch agencies could benefit from conducting energy audits to identify...
Economic and Other Implications of Switching from Coal to Natural Gas at the Capitol Power Plant and at Electricity-Generating Units Nationwide
GAO-08-601R: Published: May 1, 2008. Publicly Released: May 1, 2008.
Elevated concentrations of greenhouse gases--carbon dioxide, methane, nitrous oxide, and several synthetic chemicals--in the atmosphere resulting from the combustion of fossil fuels and other sources have the potential to cause significant changes in the earth's climate. These potential impacts include shifts in sea level and weather patterns and could pose threats to coastal and other infrastruct...
Strategic Petroleum Reserve: Improving the Cost-Effectiveness of Filling the Reserve
GAO-08-726T: Published: Apr 24, 2008. Publicly Released: Apr 24, 2008.
The Strategic Petroleum Reserve (SPR) was created in 1975 to help protect the U.S. economy from oil supply disruptions and currently holds about 700 million barrels of crude oil. The Energy Policy Act of 2005 directed the Department of Energy (DOE) to increase the SPR storage capacity from 727 million barrels to 1 billion barrels, which it plans to accomplish by 2018. Since 1999, oil for the SPR h...
Advanced Energy Technologies: Budget Trends and Challenges for DOE's Energy R&D Program
GAO-08-556T: Published: Mar 5, 2008. Publicly Released: Mar 5, 2008.
For decades, the nation has benefited from relatively inexpensive energy, in the process growing heavily reliant on conventional fossil fuels--oil, natural gas, and coal. However, in the current wake of higher energy costs and environmental concerns about fossil fuel emissions, renewed attention is turning to the development of advanced energy technologies as alternatives. In the United States, th...
Transmission Lines: Issues Associated with High-Voltage Direct-Current Transmission Lines along Transportation Rights of Way
GAO-08-347R: Published: Feb 1, 2008. Publicly Released: Feb 1, 2008.
Electricity is central to the national economy and the daily lives of many Americans, powering homes, businesses, and industries. Today, an extensive system consisting of more than 150,000 miles of high-voltage transmission lines works to provide reliable electricity service and transport electricity from power plants to consumers. Federal and state entities share responsibility for regulating the...
Energy Efficiency: Opportunities Exist for Federal Agencies to Better Inform Household Consumers
GAO-07-1162: Published: Sep 26, 2007. Publicly Released: Oct 4, 2007.
Household energy use accounts for nearly one-fourth of all energy consumed in the United States, amounting to more than $200 billion per year spent by consumers. Recent increases in energy prices have heightened consumers' interest in making their households more energy efficient. To this end, the federal government manages two key efforts--EnergyGuide and Energy Star--to inform consumers about th...
Vehicle Fuel Economy: Reforming Fuel Economy Standards Could Help Reduce Oil Consumption by Cars and Light Trucks, and Other Options Could Complement These Standards
GAO-07-921: Published: Aug 2, 2007. Publicly Released: Aug 2, 2007.
Concerns over national security, environmental stresses, and high fuel prices have raised interest in reducing oil consumption. Through the Corporate Average Fuel Economy (CAFE) program, the National Highway Traffic Safety Administration (NHTSA) requires cars and light trucks to meet certain fuel economy standards. As requested, GAO discusses (1) how CAFE standards are designed to reduce fuel cons...
Crude Oil: Uncertainty about Future Oil Supply Makes It Important to Develop a Strategy for Addressing a Peak and Decline in Oil Production
GAO-07-283: Published: Feb 28, 2007. Publicly Released: Mar 29, 2007.
The U.S. economy depends heavily on oil, particularly in the transportation sector. World oil production has been running at near capacity to meet demand, pushing prices upward. Concerns about meeting increasing demand with finite resources have renewed interest in an old question: How long can the oil supply expand before reaching a maximum level of production--a peak--from which it can only decl...
Passenger Vehicle Fuel Economy: Preliminary Observations on Corporate Average Fuel Economy Standards
GAO-07-551T: Published: Mar 6, 2007. Publicly Released: Mar 6, 2007.
Concerns over national security, environmental stresses, and economic pressures from increased fuel prices have led to the nation's interest in reducing oil consumption. Efforts to reduce oil consumption will need to include the transportation sector. For example, several Members of Congress have introduced bills proposing changes to the corporate average fuel economy (CAFE) program. This program...
