I say this because Spain doesn't have oil either, it only has 5 nuclear power plants,

I don't understand how it can be so much cheaper than Germany.
Well, you answered your own question.
I've had to look for information, because I heard that Germany is in the process of shutting down nuclear power plants or something. I found this, which I'll share for anyone who doesn't quite know what's going on:
'
BERLIN, July 18 (Reuters) - Germany may extend the life of its three remaining nuclear power plants, the economy ministry said on Monday, as public support rises in the face of a possible cut-off of Russian gas.
Germany's remaining nuclear plants are scheduled to be shut down by year-end after former Chancellor Angela Merkel pledged to phase out nuclear power following the meltdown at the Fukushima nuclear plant in Japan in 2011.
The three plants made up 6% of Germany's power production in the first quarter of 2022.'
Whereas in Spain
Nuclear power produced 20.8% of electricity in 2021.
