Schendler Part II: Good RECs vs. Bad RECs « Climate Progress: "Aspen Skiing Company’s work (”Little Green Lies“) I’ll expand on the article’s discussion of renewable energy certificates (RECs).
While the article justifiably criticized many RECs, it failed to make the point that there are good and bad RECs. (A REC represents the environmental attributes of one megawatt-hour of renewable energy.) The contrast between the two is stark. Bad RECs don’t do anything to drive new renewable energy development. A bad REC costs about $2 (though the price has gone up) and comes from, say, a wind farm that has been already developed. Your purchase may be a nice bonus for the wind farm developer (and for the REC broker you bought it from) but it didn’t do anything to change carbon dioxide emissions in the world."
