Natural gas "generation"? I don't think so. These are electric power generation facilities burning natural gas. Your previous post's headline "much more than electric" is wrong -- they're all "electric".
Wrong, Colorado is not having record cold weather. We had temperatures in the 70's recently while the east coast was suffering. We had some cold weather before Christmas but not recently. If you look at a map of global temperatures, 2014 was warmer pretty much everywhere except for a bubble of cold over the Northeast.
