fossil fuels |
fuels formed in the ground over millions of years from the remains of dead plant and animals examples include petroleum, propane, natural gas, and coal |
|
|
nonrenewable |
sources of energy with a limited supply that can not be replenished in a short period of time |
|
|
renewable |
energy that comes sources that are constantly replenished by natural processes in a short amount of time |
|
|
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 fuel appears as a brown to black colored soft rock |
|
|
petroleum |
a naturally occurring nonrenewable source 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 crude oil |
|
|
natural gas |
a colorless combustible fossil fuel formed 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 wast as fuel |
|
|
compost |
a mixture of rotting vegetarian and manure used as a fertilizer |
|
|
hydro power |
a renewable resource that converts falling or flowing water to electricity employs that use of a dam which controls the flow of a river |
|
|
tidal power |
a renewable, inexhaustible energy source that converts the energy of tides into electricity employs the use of barrages and turbine as the tide rises and falls twice a day |
|
|
nuclear power |
a nonrenewable resource that comes 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 thisoccurs, energy is released. |
|
|
geothermal energy |
a renewable energy resource that converts the heat naturally produced deep within theearth into electricity. |
|
|
solar energy |
a renewable, inexhaustible energy resource that converts energy given off by the sun intoelectricity; 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 bytemperature and pressure differences to electricity; employs the use of wind turbines to collect energy. |
|
|
Greenhouse effects |
the naturally occurring process in which gases in the atmosphere trap heat from the sun and keep the earth warm. |
