Yeah. I mean coal is still our #1 worldwide, especially in the USA as far as I know. We focus on oil but really it’s all about the coal, and unless China and India get on board, the pollution will continue. Of course we’re the problem. Even right now, I’m on my computer that runs on DC but powered by AC. I should have a solar panel charging up a few car batteries during the day and powering this thing at night. But I don’t.
