water heating and electricity. The commercial sector accounted for just 2 percent of total renewable energy consumption. The transportation sector was the fastest growing sector, consuming 40 percent more renewable fuel between 2005 and 2006. This is mainly due to increased ethanol consumption, by far the larger component of biofuels during those years. Renewable energy used to produce electricity contributed 4.229 quadrillion Btu or 61 percent of total renewable energy consumption in 2006 . Ninety percent of this energy was consumed in the electric power sector, which includes traditional electric utilities and independent power producers whose primary purpose is to sell electricity, or electricity and heat, to the public. Almost all of the remainder is used by the industrial sector. Nonhydro renewable electricity energy consumption expanded slowly from 1,278 to 1,360 trillion Btu between 2002 and 2006
More than 150 years ago, wood, which is one form of biomass, supplied up to 90 percent of our energy needs. As the use of coal, petroleum, and natural gas expanded, the United States became less reliant on wood as an energy source. Today, we are looking again at renewable resources to find new ways to use 14 them to help meet our energy needs. Overall consumption from renewable sources in the United States totaled 6.8 quads (quadrillion Btu) in 2007, or about 7 percent of all energy used nationally. Consumption from renewable sources was at its highest point in 1997, at about 7.2 quads. Picture 3.1. The Role of Renewable Energy Consumption in the Nation's Energy Supply, 2007 Over half of renewable energy goes to producing electricity. The next largest use is the production of heat and steam for industrial purposes. Renewable fuels, such as ethanol, are
