> That's the most expensive one, This is historically true. However these days natural gas is often cheaper. Of course prices fluctuate, but in general coal has been losing favor because it is expensive. Note that cheap is not just the direct fuel costs, it also includes overhead, that you can throttle natural gas often makes it cheaper overall even when the direct costs are slightly more. Also unreliable wind+solar is - when working - vastly cheaper than anything else. As such running natural gas at twice the price vs a coal plant can still be a lot cheaper just because you don't have to buy fuel when the wind blows/sun shines.
