Sweden is not dropping renewable energy. We are (at least for now) going to include nuclear energy among the other alternatives such as water, wind and solar.
But here's one of the problems we are trying to solve with nuclear power:
Sweden is a major producer of high quality steel and we have set a target to become CO2 free in 2045 when it comes to steel production.
Currently the steel production in Sweden is responsible for 5500000 metric tons of CO2 per year and we have plans to go 0 CO2 by 2045.
To be able to do this we need, just for the CO2 free steel production, 70 TWh per year.
In 2020 there were 4333 wind turbines 26TW of electricity in Sweden.
While you might think that we'd just build 9000 more it will not likely not solve the main problem with wind and solar power production: reliability.
So either we continue using fossil fuel to produce steel or we don't. It's as easy as that.
Reliability is done by redundance. Build 18000 of them. Also Sweden have plenty of hydropower as well.
Worked on windpower in Sweden and seen the maps. Shitload of potential. The real reason is who filled who's pockets.
