There’s a great SMBC comic exploring the geopolitical consequences of having Superman turn a crank to provide an unlimited source of energy. We could imagine Yoda using the Force to run a similar generator. But how much power could he really supply?
Yoda’s greatest display of raw power in the original trilogy came when he lifted Luke’s X-Wing from the swamp. As far as physically moving objects around goes, this was easily the biggest expenditure of energy through the Force we saw from anyone in the trilogy.
The energy it takes to lift an object to height h is equal to the object’s mass times the force of gravity times the height it’s lifted. The X-Wing scene lets us use this to put a lower limit on Yoda's peak power output.
