I assume you mean in the USA? Nuclear energy is supplied as electricity. You can see the nuclear plants on a map in the link given below.
Twenty percent of the worlds energy is supplied by natural gas.
Nuclear energy
Uranium is a radioactive substance. Nuclear power production is carried out by the energy supplied by nuclear reactors. Nuclear reactors control the energy emission by nuclear fission reaction in radioactive substance when bombarded by neutrons.
Nuclear energy is obtained through fission and fusion reactions.

Nuclear energy transforms to thermal energy (through nuclear fission or nuclear fusion). Thermal energy transforms into kinetic energy (eg produces steam that drives steam turbines). The kinetic energy transforms into electric energy (through electric generators).

The scientific term for nuclear energy is "nuclear power." This energy is produced through reactions in the atomic nucleus, specifically through processes like nuclear fission or fusion to generate heat that can be converted into electricity.
Germany as of 2007 they supplied 50% of the worlds solar energy
As of 2011, the UK produces about 19% of its power (roughly 10 GW) via nuclear means. Using the above metric that nuclear plants produce about 10 GigaWatts, that means the total yearly energy production of the those plants is about 87,600 GigaWatt-hours, or 315.36 TeraJoules.
