TLDR: All turbines on a electrical grid have to turn at the same speed. Hydro, Fossil fuels, Nuclear all use turbines. There is no way to dump energy into nothing to prevent the turbines from spinning too fast. So pure supply and demand capitalism is why we pay people to take our energy to allow our electrical devices to work.
