I largely agree with the other replier about most green options. I suspect that if you want to do that, the easiest thing to do is make sure you don't use more computing resources than you have to, and the second is to host it yourself and power it yourself (that can be very impractical).

There are places that are trying to offer green options, that aren't that slimy -- I have met the follow that runs http://burlyhouse.net/, and his operation is nice. His prices are high, but I think most of his customers are people who also hire BurlyHouse for programming or other services.
