I will freely admit that I have not paid a lot of attention to this, but now it has my attention (or at least more of my attention). Boulder is attempting to divest itself of its existing energy sources, replacing them with its own, for the purpose of reducing its environmental impact. A plan has been constructed which is not only viable for Boulder, but for other communities in the country. There’s a rather stirring video about it here. It’s worth watching even if you don’t live in the area.
