You should bear the cost of whether you keep your A/C at 68° or 72°, whether you heat your house with baseboard heaters or central air, whether you insulate your house so it's easy to keep it at whatever temperature you care to, whether you live in a 4000sq detached house or a 500sq apartment, whether you run a modern refrigerator or something that fell off a truck in the 50s. Paying for your electricity helps align incentives so that you can make the trade-off of investing to lower usage vs. just buying the power you want at market rate... and bearing that cost means you have the freedom to make that trade-off rather than it being made for you.
