|
Fossil Fuels |
Fuels formed in the ground over millions of years from the remains of dead plants and animals; examples include petroleum, propane, natural gas, and coal. |
|
|
Nonrenewable |
Sources of energy with a limited supply that can not be replenished (made again) in a short period. |
|
|
Inexhaustible |
Energy that cannot be entirely consumed or used up; unlimited. |
|
|
Coal |
A fossil fuel formed from prehistoric plant remains, made mostly of carbon and burned as a fuel; appears as a brown to black colored soft rock. |
|
|
Petroleum |
A naturally occurring, nonrenewable fossil fuel formed from the remains of freshwater organisms and made of hydrocarbons, can be solid, liquid, or gas, yellowish-green to black in color; also called crude oil. |
|
|
Natural gas |
A colorless, combustible fossil fuel formed from the remains of marine organisms and mostly made of methane gas. |
|
|
Propane |
A colorless, combustible fossil fuel found in natural gas and petroleum; found in gaseous state. |
|
|
Biomass |
A renewable energy source that uses plant materials and animal waste as fuel. |
|
|
Compost |
A mixture of rotting vegetation and manure; used as a fertilizer. |
|
|
Hydropower |
A renewable energy source that converts falling or flowing water to electricity; employs the use of a dam which controls the flow of a river. |
|
|
Tidal Energy |
A renewable, inexhaustible energy source that converts the energy of tides into electricity; employs the use of barrages and turbines as the tide rises and falls twice a day. |
|
|
Nuclear energy |
A nonrenewable energy resource that comes from energy stored in the nucleus of atoms, usually Uranium atoms, and is released in nuclear reactors to make electricity. |
|
|
Fission |
The splitting of a nucleus into at least two other nuclei that releases a relatively large amount of energy; the process that occurs in nuclear reactors. |
|
|
Fusion |
A nuclear reaction in which two or more nuclei combine together to form one larger nucleus; when this occurs, energy is released. |
|
|
Geothermal Energy |
A renewable energy resource that converts the heat naturally produced deep within the earth into electricity. |
|
|
Solar Energy |
A renewable, inexhaustible energy resource that converts energy given off by the sun into electricity; employs the use of photo-voltaic (PV) cells to collect energy. |
|
|
Wind Energy |
A renewable, inexhaustible energy resource that converts energy of moving air caused by temperature and pressure differences to electricity; employs the use of wind turbines to collect energy. |
|
|
Greenhouse effect |
The naturally occurring process in which gasses in the atmosphere trap heat from the sun and keep the earth warm. |
|
|
Renewable |
Energy that comes from sources that are constantly replenished (made again) by natural processes in a short amount of time. |
