In any case, a fair amount of the potentially
useful chemical energy in the coal will be squandered in the form of energy inefficiency AKA entropy before the coal is converted to steam, which is then converted to the rotary motion of the dynamo, which is then converted to electicity, which is then shipped a really long distance to be converted back into rotary motion again.
