>Because nuclear leaves toxic waste that lasts over 10000 years in the best case;

That might be theoretically true for the moment, but not in the near future. Right now waste can and should be recycled which would reduce the amount of waste. https://en.wikipedia.org/wiki/Radioactive_waste

Soon it will be possible to use most of the waste as fuel:

>...Fast reactors can "burn" long lasting nuclear transuranic waste (TRU) waste components (actinides: reactor-grade plutonium and minor actinides), turning liabilities into assets. Another major waste component, fission products (FP), would stabilize at a lower level of radioactivity than the original natural uranium ore it was attained from in two to four centuries, rather than tens of thousands of years

Most cases? How is that? The issue with most of those sources are the very low capacity factor. There are obvious reasons that (except for hydro) that currently they generate very little percentage of the world's electricity. In the case of hydro it has caused more environmental devastation than almost any power source except coal and the accidents have caused orders of magnitude more devastation than other power sources.
