What about that coal or oil fired generating plant?

Oil fired plants are becoming very uncommon as more and more of them
have converted to natural gas. Coal is being phased out everywhere
in the US. Petroleum is becoming a transportation fuel as opposed to
a stationary power plant fuel. Natural gas will eventually become a
transportation fuel also.
