Say what you will about Renewable Energy Certificates, Green Tags, carbon offsets and the like, but Intel sure does own a lot of them. Intel just became the largest purchaser of Renewable Energy Certificates in the US, with a commitment to snapping up 1.3 billion kilowatt hours a year of the stuff. RECs act as a sort of green "currency," allowing a company invest in renewable energy sources, instead of the pollution-ridden plant up the river fueled by the blood of innocents. Not a bad PR move, but the investment should make renewable energy sources more affordable down the line, so it's hard to fault them there.
