Germany € 0.29/kWh € 0.45/kWh Finland € 0.12/kWh € 0.22/kWh Damn, why is electricity in Germany over twice as expensive as in Finland? I doubt Germans have twice the purchasing power as Finns.
For nearly every country worldwide, that is gas turbines most of the time. Even if 90% of power generation is coming from solar, it's the 10% gas that sets the price (since the marginal cost of installed solar is near zero).
Gas prices in Europe vary by region, but are pretty much determined by gas transport capacities to Germany. Ie. Germany has the highest prices because of government mandates to fill storage. Any place with good gas transport links also has high prices. Places with few/no pipelines to Germany and an independent supply have low prices.
And that is why Germany is twice Finland (Finland gets gas from Norway, and neither has big pipelines to Germany).
