In the past three months, Staples more than doubled its renewable power purchases as Intel neared 100 percent renewable electricity.

The latest list of the U.S. Environmental Protection Agency's top Green Power Partnership organizations shows a few other shakeups since October, when the EPA handed out Green Power Leadership Awards.

Intel retains its number-one spot on the list, which ranks the top 50 companies and organizations based on how much renewable-based electricity they purchase. The EPA works with more than 1,300 partners through the program.

By increasing its renewable purchases by 1.1 billion kilowatt-hours (kWh), Intel now gets 88 percent of its power from renewables. In October it was at 51 percent.

Kohl's retained its second-place position by upping its purchases by 50 million kWh, keeping its purchases at 100 percent of its electricity use.

Intel and Kohl's, with their current purchases of 2.5 billion kWh and 1.4 billion kWh, are still the only organizations to buy more than 1 billion kWh or renewable energy annually.

Much of the rest of the top 10 stayed the same as October, save for one notable exception, Staples, which jumped from number 28 to 8 by more than doubling its renewable energy purchases, from 22 percent to 52 percent of its power use.

Dell, meanwhile, dropped from number 7 to 35, with green power purchases now accounting for 28 percent of its power as opposed to the 129 percent it was covering last year.

Best Buy, Drexel University and Suffolk County, N.Y., join the top-50 list for the first time, and those dropped off of the list are Wells Fargo & Company, U.S. General Services Administration/Region 2 and Austin, Texas.
