Just saying we don't need any coal shows a definite lack of understanding of the industry and the problem. I work in power system transmission, but have zero connections to either coal or nuclear. My only "skin" in the game is a deep concern for premature coal retirements based off of all the public studies which have been run.
Edit: My memory is a little foggy, but I just double-checked myself and the coal plants in ISO-NE I was thinking about were actually natural gas plants that wouldn't be impacted by loss of pipeline as they were served by a local source. If they had enough of those, you wouldn't need to keep nearly as much coal around. However, I bet they're fairly rare.
Can you explain that parenthetical? I’m at a loss.
Not to mention that using coal extends the deadline on your country's gas reserves, reduces the much-hated fracking etc.
So yes Coal is uneconomic and awful for the environment. However, it is important to recognize the value that it and Nuclear bring as they often have a minimum of 3 months of fuel on-site unlike gas, intermittent renewable, and batteries.
