Well, not to be that guy but given your specific example of a dryer there is a way you can get over half the way there. Get a heatpump dryer. They use 1/4th the amount of electricity as a standard electric dryer and can literally be plugged into a standard 110v 15A outlet they don't need the big ass 220v 50a plug. Heavy items like thick beach towels take a bit longer but otherwise they function identically
