I mean, it's obviously awesome but it is a major energy user and if your grid is pounding CO2 into the atmosphere to create that power, you're kind of compounding the problem. Creating higher temperatures that require more AC, which then creates more CO2 to cause higher temperatures, so on and so forth.
But the majority of people appear too stupid to understand this and will vote for idiots that push "Air Conditioning for Everyone!" policies that will help usher the end of modern civilization (the same people selling silly solutions tend to also be big fossil fuel shills advocates)
With that said, I wish the left would learn how to politics. "Hey, AC is awesome, we love AC, use all of the AC you want. We're going to give you the best, most modern electrical grid and society that is going to ensure that you can keep your flat 5 fucking celsius all summer if you want." Then get elected, do the green cities thing, do the green grid thing and make AC less necessary and less carbon intensive. Fucking dummies.
