If degrading yourself to a primitive life is your goal, windmills are a

Megawatts of power are generated by wind both in Holland near the
Zuider Zee, and in SW Minnesota.

You might argue that wind power is more "primitive" than fossil or
nuke-powered steam turbines, but ever-improving power
semiconductor technology is playing and will continue to play an
important role in the development of economically-effective, clean,
sustainable electric power generation from wind. The
semiconductors come into play because, while a steam turbine can be
controlled to run at a given speed, wind is variable. Controls make
it possible to maximize the output from a windmill under existing
wind conditions.
