| Term | Definition |
|---|---|
| energy efficiency | Percentage of energy put into a system that does useful work; energy not lost to the environment |
| energy distribution | how much energy is produced by each source |
| biomass | energy from living materials; wood, biofuels, etc. |
| sustainable | able to continue indefinitely |
| energy conservation | The practice of reducing energy use |
| biofuel | Fuels, such as ethanol or methanol, that are created from the fermentation of plants or plant products. |
| fossil fuels | Energy from ancient plants and animals; stored as coal, oil, natural gas, peat, etc. |
| geothermal energy | energy captured from the earth's heat energy |
| hydroelectric energy | energy captured from water movement/flow |
| wind energy | energy captured from air movement |
