Cheap natural gas has been strangling coal generation for over 15 years now. There's a reason there are no new coal plants being built in the US, and it's not for environmental reasons. It's all about economics. Now that the power companies have reduced their coal generation by 50% they are taking the opportunity to market themselves as being "green." Hogwash. They're not green - they're going after cheaper power sources. Power sources such as natural gas, wind, and solar. Notice what isn't in that list - nuclear. Nuclear in the US is simply too expensive and requires too long of an investment commitment for it to be attractive. So, it's not being done.
