Nuclear Energy is (can be) Renewable

Nuclear energy is not renewable if we discard nuclear fuel after one use.  This uses, and wastes much of, the only fissile nuclear energy source, uranium-235.  The U-235 is just 0.7% of natural uranium.

But nuclear energy is renewable if we recycle the fuel. The U-235 can then convert the billions of tons of uranium-238 [...]

We Need to Build 5,000 – 6,000 Nuclear Power Plants by the 2050s to Meet World Energy Needs

We Need to Build 5,000 – 6,000 Nuclear Power Plants by the 2050s to Meet World Energy Needs 
If we can get one-third of world energy from nuclear power sources (which is 100% of 1990 world energy use), can we get renewables and fossil fuels to DOUBLE 1990 energy use to provide two-thirds of the world’s 2050s energy [...]
