Intel will purchase more than 1.3 billion kilowatt hours a year of renewable energy certificates as part of a multi-faceted approach to reduce its impact on the environment, making Intel the single-largest corporate purchaser of green power in the United States, according to the U.S. Environmental Protection Agency. The company said it hoped the record-setting purchase would help stimulate the market for green power, which should lead to additional generating capacity and ultimately, lower costs.

The purchase placed Intel at the top of EPA’s latest Green Power Partners Top 25 list, and also at the No. 1 spot on EPA’s Fortune 500 Green Power Partners list. The EPA’s Green Power Partnership program encourages and recognizes voluntary green power purchases as a way to reduce the impact of conventional electricity use.
