They have very good thermal coeffiency: ground source heat pumps will typically generate 3-6kWh of thermal energy from 1kWh of electricity. By reversing the flow you can also use ground source heat pumps for cooling as well.

Doesn't sound like "basically free" to me... It still uses electricity, which doesn't help with climate change (even if it mostly comes from renewables).

Swedish electricity generation is 99% low-carbon sources.

I tend to stay away from topics like this which generalize and basically tell a whole continent they are living their lives "wrongly". But I have to say, AC is not "banned" anywhere in Europe, apart from certain cantons of Switzerland. In Germany you have a right to AC actually, if your community votes to "veto" the installation a court can overturn that.

Ouch, that's far too cold for me in the UK. I have the house at 20C during the day (68F), and only drop to 18C (64F) at night.

When I had poor insulation that meant heating was regularly on 8 months a year, although it's on less now I live in a well insulated house.

Very strange take, you can buy an airco unit in the EU today get it delivered tomorrow morning and, assuming it's the portable kind that just need to be plugged and exhaust outside, have it running right away. For more permanent ones you might need a professional to install it if you don't know yourself. There is absolutely 0 barrier if you need or even just want one. Proof in Belgium : https://www.coolblue.be/en/air…

I live in France. That kind of aircon is garbage both in how much it can cool a room and how efficient it is due to under pressure.

You can get a portable split-system if you have a balcony.

But installing a real full-size AC with a large external unit is prohibited in most cases. If you’re renting you’re of course out of luck. An apartment, even one you own-forget it.

You might be surprised how far you can get with a simple fan. What your body needs is to evaporate heat. You sweat, it evaporates, skin cools down. Airflow helps that process a whole bunch. It's physics. It may not make hot weather feel perfect but it will cover the necessity pretty much anywhere. Same goes for tree shade and sensible city planning, also architecture (see all those textured dark grey or black condos…

I think you're under-estimating how hot it gets inside well-insulated European homes. Your mileage may vary across European countries, but in the north where it gets cold in the winter our homes are built to trap heat. Opening windows won't get you very far as the temperature radiates through the windows and traps in the walls. Closing blinds will help, but not by much. It got over 40c in my office this summer. This…

When it's around 20C, it's impossible for me to make my rooms colder than say 23C, because there is no way I can make so much of air exchange.

Even if I somehow manage to pull the air in, the moment I close it - the walls that have all that heat will start giving it back again, bringing the temperature back to where it was.

It's so funny, that when the winter starts, it's long into the winter before I have to turn on heating in my apartment.

I think even when it's 45C and your boomers cook alive in their concrete ovens, I will still see these sneering opinions from the enlightened master race, civilized to the point of welcoming their own extinction to preserve the klimat for someone else's children.

Lazy climate change denialism, nobody is convinced.

You should come to Texas and tell me how well you get along with just a fan. We have had like over 40 days of 40-45 C in a row. The wind feels like a blast furnace and at night it can still be 38 C outside. Even the birds have fled to cooler locals. It is so intense that you can not walk barefoot outside around your home. If your car broke down on the side of a road, you would be dead in less than an hour, even in the shade. I like to tell people that Texas is the next stop after Hell and too be honest it is like living in the Arctic compared to Arizona where the temps are even worse.

I was in Vienna this summer and the inside of the apartment was over 40 for the entire week. Thank god, we were able to buy a portable AC unit from Mediamrkt before they ran out.

Fans stop cooling you once air temps approach body temperature. The EU sees tens of thousands of excess deaths each summer, mostly among the elderly.
