I've been hearing a lot about going carbon neutral. The concept is pretty simple and thousands of years old. For every sin one must pay penance. And while we don't think about it much websites do contribute to global warming by using energy. While using energy is unavoidable even with conservation, one can offset the negatives by using your resources (typically money) to do things that will decrease the impact in other areas. Well, my host server has gone carbon neutral and, ipso facto, so has my website. I take no credit for this, but I'm pretty happy they take it seriously.
