These calculations seem WAY off... 1) EVERYONE ON ELECTRIC? It seems like there is an assumption that 1kwh of energy is used without first determining if the water is heated by GAS or ELECTRIC. Gas require far less energy to heat the water, that is IF you really need... 2) HEATED WATER? The second assumption is that people are using HEATED water! Who says you have to heat the water. 3) If people use LESS that 3-5 gallons on average with hand washing then washing dishes by hand comes in FIRST place. It's actually VERY easy... it's called soak (with soapy water), wash and rinse! 4) Bravo for including information about Phosphate-free detergents I'm surprised I did not find an affiliate link for washing machines and electric hot water heaters on the same page!!
