In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
Uranium and thorium mines are just as clean as the rare earth metal mines needed for PV cells. This is kind of a moot point. We need carbon free energy now and solar, wind, hydro, and nuclear are all part of the mix of solutions needed. There are many considerations currently being made to determine which technologies should be used in what locations.
