I'm having to adjust the energy use for heating fact some of that heat actually goes into hot water. So the calculator is figuring how much heat is needed to heat the water you use for washing, and subtracting that from the total amount on your energy bill (the remainder of which is heat). Yeah - one of the things i learned building this is the huge amount of energy it takes to move humans anywhere (in cars/planes). News articles often mention trivial things like turning off phone chargers, when the energy consumption from car use dominates total energy use from electricity for most households. Electric cars are genuinely a lot better in this regard, and the payoff period for the embedded cost of manufacture is lower than many people think: https://www.robinlinacre.com/carbon_electric_car/ https://www.robinlinacre.com/carbon_electric_car/
