| Term | Definition |
|---|---|
| Biomass Energy | is energy that is produced from this material |
| Biopower | electricity that is generated by the combustion of biomass |
| Geothermal Energy | is the thermal energy present inside Earth, which can be harnessed to produce electricity and meet other heating needs |
| Ground source heat pump | takes advantages of the fact that the temperature of soil a few feet underground stays about the same all year, even though the air temperatures changes with the seasons |
| Hydropower | we use the kinetic energy of moving water to turn turbines and generate electricity |
| Tidal energy | refers to using the movement of tidal water to generate electricity |
| Ocean thermal energy conversion | is a process that converts the thermal energy in ocean water to electrical energy that people can use |
| Passive solar heating | involves designing a building to collect, store and distribute the sun's energy naturally |
| Active solar heating | system uses technology to collect, move, and store heat derived from the sun |
| flat-plate solar collector | generally consists of a black, heat-absorbing metal plate in a flat box with a glass cover |
| Photovoltaic | solar energy is converted directly into electricity |
| Concentrating solar power | is a technology that uses mirrors to focus sunlight in order to generate electricity |
| Wind turbine | is a device that converts the wind's kinetic energy, or energy of motion, into electrical energy. |
| Wind farms | wind turbines are most often built in groups called wind farms |
| Electrolysis | water molecules are broken down into oxygen gas and hydrogen gas by an electric current that runs through the water |
| Fuel cells | hydrogen gas can be used to produce electricity within fuel cells |
| Biofuel | liquid fuels from biomass sources known as bio fuels |
