Eliminating the PTC will make it harder for progressive companies to meet their renewable energy commitments. Sprint, for example, has a target of getting 10 percent of its energy from renewables by 2017.
The letter, sent by the group Business for Innovative Climate and Energy Policy (BICEP), which is part of Ceres, argues that allowing the 2.2 cent per kilowatt-hour incentive for wind production to lapse would amount to a tax hike on American businesses that buy renewable energy.
"Extending the PTC lowers prices for all consumers, keeps America competitive in a global marketplace and creates homegrown American jobs," says the letter.
Companies signing the letter include Akamai Technologies, Annie's Inc., Aspen Skiing Company, Ben & Jerry's, Clif Bar, Johnson & Johnson, Jones Lang LaSalle, Levi Strauss & Co., New Belgium Brewing, The North Face, Pitney Bowes, Portland Trail Blazers, Seventh Generation, Sprint, Starbucks, Stonyfield Farm, Symantec, Timberland and Yahoo!
