That massive spike of 50c/kWh at the left looks tiny compared to today even though that’s already insanely expensive
minus-square@[email protected]linkfedilinkEnglish4•1 year agoTo turn gas to electricity assume 50% efficiency. 2MWh of gas = 1MWh of electricity.
minus-square@[email protected]linkfedilinkEnglish4•1 year agoSo given that most gas furnaces (at least in the US) operate at 90-95% efficiency, does that mean 20 kWh of resistive electric heat (as measured on the bill) provides similar heat to ~11 kWh of gas?
minus-square@[email protected]linkfedilinkEnglish3•1 year agoIt would equal about 22kWh of gas, since gas isn’t 100% efficient like electric heat is.
minus-square@[email protected]linkfedilinkEnglish1•1 year agoAh. 50% efficency to turn gas into electricity. If you are just making heat then burning gas directly is much better.
