The world needs a new source of energy, an unspillable source.

Does anyone know what the name of the PBS documentary where the couple stops using coal and nuclear energy?

There was a documentary about energy consumption in America where the couple wanted to be zero emissions. It talks about nuclear energy and coal plants and everything. They end up reducing energy and buy carbon shares or whatever those are called to become essentially zero emissions.
Both of those are incorrect. This was a low budget story that appears to be filmed and narrated by the husband.

They go into detail about where Uranium comes from. It’s nothing political, really. More like a challenge for themselves to see if they can not use any “dirty” energy.
