Intel Corporation is the largest voluntary purchaser of green energy in the United States, according to the Environmental Protection Agency. By the end of 2010, the company was able to reduce greenhouse-gas emissions by more than 40 percent. In 2011, the company purchased enough renewable-energy credits to cover 85 percent of its U.S. energy use. The resulting reduction in emissions will be equivalent to the energy use of more than 200,000 American homes. Additionally, the company created nine solar installations in 2010 in the U.S. and Israel, which combine to generate more than 3.8 million kWh of solar energy per year.
