I agree. It may not necessarily be the most cost-efficient source of electric power, though.
Perhaps not at this moment with nat gas coming out our ears.
Its useful to consider the “rank” of various fuels. Coal is a low rank fuel, requiring infrastructure, handling, rail hauling and ash disposal. Gas is a high rank fuel. It can be pushed through a pipe and when it arrives where its needed, can be burned, used as motor fuel, reprocessed into chemicals, etc. Crude oil would be considered mid-rank. Easy to transport but requires several steps at an oil refinery.
