If you look at the map and click on the various plants listed, you will see that they are listed as being closed, not converted to natural gas. I don't hear of any new NG plants being built near where I live to replace the coal-fired ones that are being closed.
The assumption seems to be, "Well, since the economy is down, we don't need that extra capacity."
The fact is that the loss of that capacity will not help the economy recover.
It is a joke.......
