AC-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.
