Well, my wife and I decided a while back to have solar power installed on our home. We sat down and really did some number crunching and with some of the incentives and all we decided that it was a good investment that pays off in the long run in a place like Colorado that gets a lot of sunshine. They installed it about 2 weeks ago, and it is working great. We've had pretty nice weather this month and our electric meter has run freakin' backwards! How cool is that?
Our decision to do this was pretty much financial all the way, but it really is a win-win situation.
