    Study Notes

    Fossil Fuels in Thermal Generation

    • Coal, oil, and natural gas are all fossil fuels.
    • They were formed from plants, animals, and micro-organisms millions of years ago.
    • When these organisms died, the energy in their cells remained "locked up".
    • These fuels can be burned to heat water.
    • When fossil fuels are burned, they produce significant amounts of energy.
    • For this reason, fossil fuels have historically been an important resource for energy production.
    • However, fossil fuels are non-renewable resources.

    Using Radioactive Materials in Thermal Generation

    • After World War II, generating electricity using uranium became popular.
    • In this process, long tubes called feeder rods are filled with the radioactive form of uranium.
    • These rods are then placed inside a reactor.
    • When a neutron collides with the radioactive uranium, a very high energy reaction called nuclear fission takes place.
    • The nuclei of the uranium atoms break apart and release huge amounts of energy in the process.
    • This energy is then used to heat water, producing steam (Figure 6).
    • Thermal generating stations that use nuclear reactions to produce energy are called nuclear generating stations (or power plants).
    • Uranium is a limited resource, like fossil fuels.
