GE offers the widest range of heavy duty gas turbines available, ranging from 26 to 480 megawatts
But natural gas is a by product, or a stand alone hydro carbon field unassociated with liquid crude. It isn't specifically refined from crude.
The basis of my argument is:
No matter how many tons of coal you replace by other means in the generation of electricity, it will not reduce our demand for oil by any significant amount.
