Update your knowledge of nuclear power. Mining can be done cleanly or not at all, and nuclear power plants generate very little waste - most of the waste that exists is from bomb making.
Newer fission tech has a lot of promise... if people who are convinced they already know all about nuclear energy can be troubled to learn about it.
What we know about it is that it is the most expensive alternative. Building, operating, and maintaining a new solar installation is cheaper than just operating and maintaining a nuke steam generator, ignoring the huge construction and decommissioning costs.
We finally got the ramshackle Indian Point and Diablo Canyon contraptions shut down, after decades of constant effort, and now it will cost a billion dollars and a decade or two to take them apart.
