Nuclear fission is considered to be nonrenewable energy because it involves uranium, a non-renewable resource, being mined and extracted from its ore. We will run out of it just as we will run out of coal, gas and oil. Uranium-235, the primary fuel for nuclear power, has an abundance of 0.7% percent in the Earth. An enrichment of 4% to 5% is required in order to achieve an effective fission reaction, and the half-life of uranium-235 is about 70 million years.
