PURCHASE, N.Y., April 30 PepsiCo announced the largest purchase of renewable energy certificates ever Monday, matching electricity used by all U.S. company facilities.PepsiCo's reported three-year purchase includes more than 1 billion kilowatt-hours annually, the estimated amount of electricity needed power nearly 90,000 U.S. homes each year.The move puts the soft drink and snack food giant in the forefront of "green power," renewable resources such as solar, wind, geothermal, biogas, biomass and low-impact hydro. Those energy sources are considered cleaner and have a superior environmental profile than conventional sources of electricity.This endeavor also puts PepsiCo atop the U.S. Environmental Protection Agency's list of top 25 green power purchasers.Copyright 2007 by UPI
