Most people who are against nuclear power, have the following reasons:
- it's the most expensive form of energy due to massive regulations
- the power plants take way too long to build
- nuclear waste is a problem, no one wants to have it buried near their homes
- the fissile material is already rare and difficult to come by, mostly sourced from politically difficult regions, such as fucking Russia
Nuclear power is not a solution.
Mate, they closed the power plants because they have long surpassed their design operating hours. The upkeep alone costs so ridiculously much, no one can pay that kind of shit. Germany has even postponed the closing date due to the immediate crisis the Russians have created.
