Domestic wind power continues to grow
Last year, the U.S. wind industry installed 10,010 MW of generating capacity, breaking U.S. installation records for the third year in a row, says the DoE. Total supply at the end of 2009 was exactly 34,863 MW of wind power installed. The top five states for installed capacity include Texas, Iowa, California, Washington, and Oregon. According to the American Wind Energy Association, wind capacity added in 2009 generates enough electricity to power the equivalent of 2.4 million homes.
Energy: Top three domestic sources still petrol, gas, and coal
According to the Energy Information Administration, the top three U.S. energy sources are petroleum, natural gas, and coal. But where does it all go? Electricity generation is our leading form of energy consumption, says the Institute for Energy Research (IER). Transportation weighs in as the next biggest consumer of energy, with much of it used to move products to their intended markets. U.S. industrial output is in third place for energy consumption. At a distant fourth, homes and businesses consume only about 10% of the national energy budget, according to IER.
Renewable energy use rising worldwide
Renewable energy's share of worldwide electricity generation is expected to rise from 18% in 2007 to 23% in 2035, says the Energy Information Administration (EIA) in its 2010 International Energy Outlook. World renewable energy use for electricity generation is forecast to grow by about 3% annually, with renewables making up 23% of the world's electricity generation by 2035, according to the report. Of the 4.5 trillion kilowatt-hours of increased renewable energy generation over the projected period, EIA says 54% will come from hydroelectric power and 26% from wind. Biomass for heat and power production currently provides the majority of renewable energy consumed in the industrial sector at 90%, and is forecast to remain the largest component of the industrial sector's renewable energy mix through 2035.
