The power goes out for a day, sometimes days, every year in my neighborhood when the wind blows. Finally fed up, I recently had a generator installed that attaches to the natural gas line.
I know that purchase was effective, because a week after it was installed there was a big storm and power went out everywhere except my neighborhood. Just having a generator successfully wards off power failure, you never have to actually turn it on.
I submit this is objective proof that I am living in a simulation and none of you exist, you're just artifacts of the simulation.
