Price of electricity in Finland peaks at 2.35€/kWh today. Keeping my tiny granny cottage warm costs me over 50 euros for a single day. It's negative 25C (-13F) outside.

That massive spike of 50c/kWh at the left looks tiny compared to today even though that's already insanely expensive

Interesting.
At these temperatures, I can't imagine air source heat pumps being very efficient.
I would probably have a spare gas, oil or wood based heater and use that for days like this, or for if the power goes off on days like this.
Older houses definitely have them... but there was this trend at some point to renavate older houses and remove the oil heaters and fireplaces and wood heated saunas, and replace everything with electric ones. Why? No idea, trends are weird.
Electricity is usually less polluting than the various fuels, wood fires especially will fill a valley with smoke, the rest are mostly to avoid the carbon dioxide
Carbon monoxide too... and chimney fires... don't forget about indoor emissions with open stoves... Even if you don't care about the environment, electric wins the health&safety race by a landslide. Forgetting to do the maintenance on a heat pump doesn't exactly carry the same risks as with a wood stove.
Heat pumps are expensive and electricity can vary in price (who in their right mind opts in to spot pricing without on-site power generation tho, what the hell). Still, it's not hard to see why everyone who can afford it is electrifying.
Also Russian fossil fuels
Newer models are actually.
We had negative 30 C the last two days and our air-to-air kept the whole upper floor comfortable. 90 m².
Granted it's a brand new and very well insulated house, but -30 bites well on those too!
Most houses up here have other electric alternatives or a fireplace.
Gas and oil are beyond abnormal to have and I think oil is even illegal in Norway now...
Don't quote me on that though
Wow, air to air even?
But do you know what the COP is at -30?
Here is a link to it
I must make a small correction though: The last night with -30 it struggled a bit. Only managed to keep the upper floor at 19 °C so we had to turn on the cables to get over the peak.
I'm still mightily impressed by it though!
Max consumption was 32 kW/day, so roughly 4-5 € pr/day with our prices.
Heat pumps only work to about -4c.
