Re:Big Coal Plants Begin to Close

They are closing because alternatives are cheaper, which has multiple reasons, some of which are policy (subsidies/penalties, publicly funded research in alternatives, stricter mining regulation driving resource prices up, stricter emissions regulations requiring expensive plant upgrades or more expensive new construction etc.)

I did a little googling, and new coal plants in the US are no more expensive - price/mwh held steady at $95-100 from 2010-1015 (after which no one built any more). Meanwhile, in 2010-1019, natural gas plants dropped in cost/mwh by about 50%, from around $80 to $40. And onshore wind dropped 71%, from $149 to around $43. Solar dropped even more (88%), from $396 to $49!
As an aside, new nuclear dropped from $119 to $90, and there are no new plants planned - small wonder, considering the massive cost and long time frame to build nuclear when wind and solar cost half as much and prices are still dropping like rocks.
