"Will the U.S. Ever Build Another Big Coal Plant?"
Yes. Of course.
It may take some time -- decades, or longer.
But new coal plants will have to be built. Many of them.
Nuclear power is fini for the short term.
No one (outside of a few vested interests) wants it (sorry for the nuke guys in the forum).
Natural gas is great, as long as it lasts.
But it won't last forever.
When the gas flares out, the coal will come roarin' back.
