I don't think anyone here moralises Aircon. It's something that's most used during periods of sun so it's really mostly powered by renewables. During the times of high ac usage there's always an energy surplus from all the solar panels around these days and the electricity distribution has trouble dealing with it all.

Maybe off topic:

Someone is working *really hard* to make this political. And a lot of people on both sides are buying it. Resulting in long essays like this one...

In the mean time (a) dual AC system for heat/cold is pretty standard in many European countries and (b) nobody is stopping you from doing anything.

If you can get hold of one, go ahead and install an AC. Install five for what I care. The inverter system is very efficient and you will probably not have the cold on for more than a few weeks per year anyway. And that during a time where Europe usually produces more power from solar panels than the infrastructure can handle..

Ignore whoever told you it's bad for the environment. Also ignore anyone who told you the green conspiracy is killing the elderly by the millions.

Now go and have a great summer.
