In 2008, businesses in the Green-e Marketplace program voluntarily purchased more than 2.8 million megawatt-hours of Green-e Energy Certified renewable energy, which is a record, according to the Center for Resource Solutions.
Intel made the largest purchase of renewable energy in history, with a 1.3 million megawatt-hour purchase in January. PepsiCo and Mohawk Paper followed behind.
Green-e Energy certified 69 percent of the overall voluntary renewable energy market in 2007.
Wind and solar industries currently make up about 7 percent of the total renewable energy market, but they are expected to contribute more than 25 percent to renewable energy by 2030, according to Credit Suisse research forecasts.
