Solar panels doesn’t provide heat, it produces electricity. Also it is quite common on Finland to have solar panels + geothermal heating, because both of them pay for themself in 5-10 years. Unfortunately solar panels do not provide us enough electricity to be only source, not even with batteries.
In Sweden it’s quite common to heat single family homes with geo. Here is a report I found from where table T2.6 breaks down different heating. Link to the
Excel sheet
As of 2021 14% used geo (berg/jord/sjö) roughly translated ~ bedrock/ground/lake.
And 10% used geo in combo with something else, usually some sort of wood burning stove.
Geothermal is expensive and not worth it financially in many countries but when you are looking at 2.35€/kWh it seems like a great investment.
He doesn’t mean geothermal in large scale but home level geothermal. It is actually very cheap and efficient technology.
Over half of the new houses in Finland are build with geothermal. It costs roughly 18 000€ to construct.
I understand, but it’s not cheap when compared to solar
