It’s a bit more complicated. Where are you gonna bury it? It has to be somewhere, where normally nobody is. Also you have to keep the waste containers safe (and in one piece) for a very, very long time. How are you gonna mark it that people thousands of years in the future still know that it is dangerous?

Nuclear is the best option. It’s the cheapest when considering the energy output, most environmentally friendly, and takes up the least amount of space.

It’s the most environmentally friendly, if you don’t consider that it is not renewable and that there are no waste management solutions for the highly radioactive waste.
