http://www.eia.doe.gov Each Energy in Brief concisely answers an energy question of importance to the public. The Briefs clearly explain the meaning of EIA’s energy data and analyses and link to more information from EIA. en-us Thu, 01 May 2008 00:00:00 EST http://www.eia.doe.gov/images2/eiasmltitle.gif http://www.eia.doe.gov/ US Energy Information Administration http://tonto.eia.doe.gov/energy_in_brief/electricity.cfm Thu, 09 May 2008 14:00:00 EST Many technologies and fuels are used to generate electricity at power plants, which is then delivered to consumers through a complex network of lines and equipment known as the "grid." The price that consumers pay for electricity is determined by weather factors, fuel costs, consumer demand, and regulations. images/thumbnails/electricity-thumb.jpg http://tonto.eia.doe.gov/energy_in_brief/foreign_oil_dependence.cfm Thu, 01 May 2008 07:00:00 EST The United States imported about 60% of the oil we consumed during 2006. About half of these imports came from the Western Hemisphere. Our dependence on foreign oil is expected to decline in the next two decades. images/thumbnails/oil-tanker-thumb.jpg http://tonto.eia.doe.gov/energy_in_brief/renewable_energy.cfm Thu, 01 May 2008 07:00:00 EST Americans used renewable energy sources--water (hydroelectric), geothermal, wind, sun (solar), and biomass--to meet about 7% of our total energy needs in 2006. images/thumbnails/renewables-thumb.jpg http://tonto.eia.doe.gov/energy_in_brief/greenhouse_gas.cfm Thu, 01 May 2008 07:00:00 EST Greenhouse gases trap heat from the sun and warm the planet's surface. Of U.S. greenhouse gas emissions, 87% are related to energy consumption. Since 1990, greenhouse gas emissions in the United States have grown by about 1% per year. In 2005, about 21% of the world’s total energy-related carbon dioxide was emitted by the United States. images/thumbnails/ghg-thumb.jpg http://tonto.eia.doe.gov/energy_in_brief/liquefied_natural_gas_lng.cfm Thu, 01 May 2008 07:00:00 EST The United States imports about 16% of the natural gas we consume. Most of these imports are delivered by pipeline (from Canada). But a growing volume of natural gas is coming to the United States in liquid form from overseas. With the demand for natural gas expected to increase, it's likely that U.S. imports of LNG also will need to increase. images/thumbnails/lng-thumb.jpg
