Uranium, the most common fission fuel, and is present in the ground at relatively low concentrations and mined in 19 countries.[9] This mined uranium is used to fuel energy-generating nuclear reactors with fissionable uranium-235 which generates heat that is ultimately used to power turbines to generate electricity.[10] Renewable energy and energy efficiency are no longer niche sectors that are promoted only by governments and environmentalists.

breeder reactors, and when it is developed, fusion power, among conventional renewable energy sources, such as solar and falling water.[6] The American Petroleum Institute likewise does not consider conventional nuclear fission as renewable, but that breeder reactor nuclear power fuel is considered renewable and sustainable, before explaining that radioactive waste from used spent fuel rods remains dangerous, and so has to be very carefully stored for up to a thousand years.[7] With the careful monitoring of radioactive waste products also being required upon the use of other renewable energy sources, such as geothermal energy.[8] The use of nuclear technology relying on fission requires Naturally occurring radioactive material as fuel.

For example, water is composed of two hydrogen atoms bonded to one oxygen atom: the chemical formula is H2O.

A compound can be converted to a different chemical composition by interaction with a second chemical compound via a chemical reaction.

The localized deposits of metal ores near the surface which can be extracted economically by humans are non-renewable in human time-frames.

There are certain rare earth minerals and elements that are more scarce and exhaustible than others.
