The first part is true, Germany has had the most expensive energy in Europe for a decade and it has some outrageous prices now, but the second part is not true, prices haven't gone up by 10x.

Just one quick look at the offers on the market and you can see that they haven't gone up anywhere close to that.
One of the most expensive ones, like E.ON is offering 56,35 ct/kWh for new clients, guarantee tariff till 8.2023


But there are "cheaper" alternatives, you can compare prices here.

That being said, nobody in Germany has seen 5cents per kWh this century, from the bills I have from one friend since I had this discussion before the used to pay 26 cents per kWh during 2019, now he is on 47 cents. Still expensive but no way near 10x.
