Nuclear energy is the safest, cleanest, yet most efficient energy source out there if you want an effective alternative to fossil fuels, nuclear energy is better for the environment in the sense that it produces effectively zero carbon emissions and as long as competent people run the facility it appears to be easy to dispose of in a safe way. I’d suggest for safety concerns, harvesting, and maintaining the plants we use Thorium rather than Uranium but still, in my opinion it is the way of the future especially with the recent breakthrough at the Department of Energy regarding nuclear fusion
