I agree with you about scorekeeping, but you did a weird comparison in your sentence about heating/cooling. You compared the potential of one with the reality of another. As in, AC can be powered by [renewable] electricity, but that most heating is [powered] by burning fossil fuels. It might be reasonable to ask how much AC actually is powered by renewables vs fossil fuels. Heating can also be done electrically, and therefore could be done with renewables. We all know that it's hella expensive at present to heat with electricity compared to natural gas, propane, or even wood in some places (at present).
- throwawaygh 5y agoAC-heavy environs -- especially deserts -- are a better use-case for existing renewable solutions than colder environs. And, also, actual uptake is higher. Solar can be more easily used for AC in desert environs because peak demand coincides exactly with peak production. And, it actually is. At least in places with access to capital. The situation is sadly exactly the opposite up north. For everything except geothermal the peak production (both in time of day and season) doesn't match up well with the peak demand. Also, AC requires a lot less energy than heating, regardless of generation method. But deserts have other sustainability issues. Water.
