Why is nuclear energy considered a nonrenewable resource? Nuclear radiation does not run out.
It comes from radiation from the sun.
Uranium ore is replaced on a geologic timescale.
Uranium replenishes more quickly than it is being used.

You could classify nuclear energy as nonrenewable because uranium and similar fuel sources are finite. On the other hand, some people consider nuclear energy renewable because the element thorium and other new technologies may provide infinite fuel needed to power nuclear reactors.
