As someone that is in the process of buying a new home and looking for efficient appliances for the specific purpose of lowering utility bills, I really appreciate the DoE's energy standards. I especially appreciate that energy start certified appliances are consolidated here for browsing. It has so far helped me choose a washer and dryer. Similarly, the EPA's WaterSense program is helpful because I live in the southwest, which is a desert. Water rationing is inevitable, and I'd like to get ahead of the game.
So, it's funny to me that efficiency standards are a culture war target. Consumers opposing these standards are basically arguing for their own exploitation by utility and gas companies.
