  >Don't save electricity. Switch to high efficiency electrical appliances (notably heat pump heating, cooling, water heating) We can do both - switch everything to electric, and simultaneously adopt habits that limit waste of these. Obviously, don't save electricity by using carbon intensive energy sources, that'd be counterproductive. I agree with the rest of your comment.

  > Switch to ... heat pump ... water heating Given that where I live installing a heat pump water heater costs over 20 years' water heating electricity consumption for me, and it would still use some electricity, so the payback period would be even longer: no, thank you. Every so often I do the calculation to see if replacing my fridge would be worth it. The payback period is about 15 to 18 years for that. A new fridge would have more even temperatures throughout the cabinet and better temperature control, and be quieter, so I still review it every now and then. Obviously my internal discount rate for investments is over 6.7%.
