I agree with everything except the blanket need to make all of these things mandatory without some sort of aid (such as a subsidy) and the bit about banning home furnaces. Homes built today might not be around by the time the grid is carbon neutral. Burning fuel for heat is absurdly thermodynamically efficient compared to burning fuel to heat water to spin a turbine to induce a current to push electrons around over miles to resistively heat a coil. The grid has a very long way to go before home furnaces become less pollutant than home electric heaters.

- TheSpiceIsLife 6y agoWhenever you believe you are so certain of a thing that you’re prepared to say something like “x could never do y” you should search the internet for x doing y. Heat pump water heaters for either space heating or hot water production are most certainly a product you can buy today. Eg, Rheem sell these two models in Australia https://www.rheem.com.au/products/residential/heat-pumps https://www.rheem.com.au/products/residential/heat-pumps
