| fossil fuel The energy-containing materials which were converted over many thousands of years from their original form of trees, plants and other organisms after being buried in the ground. Physical and chemical processes occurred in the Earth's crust that changed them into coal, peat, oil or natural gas | breosla iontaise |

| non-polluting fuel Clean fuel that does not release polluting emissions in the environment, such as methane | breosla neamhthruaillitheach |
| nuclear fuel Nuclear fuels are obtained from inorganic minerals extracted by mining. Although they are at least partially consumed when used in nuclear reactors for the production of heat, they differ from fossil fuels in the way they release energy. Burning of fossil fuels, such as coal, oil and gas, is a chemical reaction. Nuclear fuels, such as uranium, are destroyed by a process of spontaneous disintegration, called fission, and prompted by natural radioactivity. If the process is left to occur naturally in uranium-bearing rock, the rate of change is imperceptibly small. In a man-made nuclear reactor the energy-releasing processes of disintegration, which in the natural state happen slowly over thousands of millions of years, are compressed into minutes. The release of energy is harnessed to generate steam which drives electricity generators | breosla núicléach |
| nuclear fuel element A piece of nuclear fuel which has been formed and coated, and is ready to be placed in a reactor fuel assembly | gné de bhreosla núicléach |
| refuse derived fuel Fuel produced from domestic refuse, after glass and metals have been removed from it, by compressing it to form briquettes used to fuel boilers | breosla a thagann ó dhramhaíl |
| solar fuel | grianbhreosla |
