Your battery solution for the TV doesn&#x27;t reduce the energy waste, it just spreads it out in time. It&#x27;s now 20W wasted 24 hours a day instead of 60W for 8 hours a day. Same difference.<p>Until our houses are powered by 100% renewable energy, any technology that sacrifices more than half the input energy just so someone doesn&#x27;t have to see an extension cord should be banned by law.
