Your battery solution for the TV doesn't reduce the energy waste, it just spreads it out in time. It's now 20W wasted 24 hours a day instead of 60W for 8 hours

Your battery solution for the TV doesn't reduce the energy waste, it just spreads it out in time. It's now 20W wasted 24 hours a day instead of 60W for 8 hours a day. Same difference.
