It's not just about being "green," it's also about conserving energy, which is just a wise choice no matter how you look at it. We don't have an endless source of energy, it's not something that will just exist until the end of time. It's about being a responsible steward over the resources God gave us. But, I know... we're
Christians, so we don't "worry" about that. GOD will provide us with energy if it be His holy will....

(I'm not preaching at anyone... for the record, I'm not the least bit "green" myself... just tossing out a thought or two).
