Wow. Whole Foods, a grocery chain in the US, is buying wind credits for 100% of its projected energy usage for 2006. They can’t hook up each store to a special renewable-energy grid so the way you get around it is by buying credits which pays for renewable energy to be fed into the grid at some other location.

Whole Foods goes with the wind

Aside from the obvious reasons of being good for business, ie: there’s no way to make money if there’s no world to live in, it’s also great marketing. If I still lived by a Whole Foods I’d be even more likely to shop there. I did shop there, but mostly for specialty items. I found it a bit expensive for my every-day shopping, but if the company is willing to do this they deserve more of my money.
