No it is not. Night, winter and cloudy days prevent this without some sort of energy storage. Are you proposing hydrogen as the storage medium?
My fault for not making more clear that annual energy is balanced;sometimes you send(sell) power to the grid, sometimes you take(buy) from the grid. LARGE batteries can be used to store a few days of power .
I don't advocate shutting down coal-fired plants but using American coal. Why not burn solid fuels in place and liquid fuels in motion.
There is a lack of appreciation for APPROPIATENESS;no one fuel or power source can do all things well. (A solar chain saw is silly unless you are willing to pull a wagon with a BIG battery.)
