The Starbucks Experience

I have more respect for the company now, yet still wonder how paying twice as much for “green” energy is good stewardship. Why not use cheap, proven energy and donate your savings to a worthwhile charity? The only thing empirically green about “green” energy is all the money its vested promoters are raking in. I'm all for good stewardship of the earth and its resources, but I'm also pro common-sense.
