Except when it isn't - see Japan.Nuclear power is the absolutely most environmentally friendly way to make electricity there is.
The environmental impact of that alone would be massive. Imagine all the machinery, spoil (taking it out and putting it somewhere), transportation, logistics, people etc.One should build them inside mountains or into the ground for safety reasons if you ask me,
I'm not agreeing or disagreeing with you, just trying to emphasise that each option has it's pros and cons as we all know. Maybe nuclear fusion?
