The article focuses on the renewable energy credit (REC). RECs were invented in the late 1990s as an offshoot of green pricing programs. With green pricing, customers paid an extra 1-5 cents per kilowatthour to buy energy from renewable sources, mostly wind, biomass, geothermal, and solar. RECs remained little-known instruments until 2004, when big companies discovered them as a convenient way to green up their power. REC retailers estimate they sold more than 6 million MWh in 2007. Officials who track green energy markets at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) in Golden, Colorado, expect yearly REC sales to hit 20 million MWh in 2010.
