The second law of thermodynamics implies that one must spend energy as work to move thermal energy up a temperature difference. So the net effect of an air conditioner is to increase the total amount of thermal energy.
It's already silly coming from the US, but jumping to the conclusion that a random comment, on a US-based forum, is propaganda specifically for a German political slapfight, is a very funny form of political egocentrism.
it's the Prisoner's Dilemma - AC helps the individual at the expense of those outside, for whom it is now hotter (can raise ambient air temp by 2-4C). It worsens global warming in how it is powered (on hot days might have to fire up peaker plants using gas) and leaks of refrigerants.
Yes but as long as there's no international agreement where we either all stop using AC to "save the planet", then individuals will optimize for their survival and comfort, which means using AC.
You can't force people to downgrade their lifestyle when they see that only applies to them and not to other people on the planet, making their suffering in vain.
During the day once the room is cold my minisplit spends around 800w keeping the room cold. Say, what happened to those 800w? Where does that go?

> This is more eco-communist propaganda cope from German greens
Strong words coming from someone who's Austrian.
> to justify why their people should keep suffering hot summers living without AC while the other parts of the world and Europe do it just fine.
That was not my point. My point is, ACs aren't a panacea. We cannot let the planet heat up indefinitely because AC has fundamental limits.
