what are the advantages to nuclear fuel
it do sent produce carbon dioxide or sulfur oxide
what are the disadvantages to nuclear fuels
they are non renewable like other fossil fuels
what type of energy does wind turbine use
wind energy and kinetic energy
what are the advantages of using wind turbines
Wind is a renewable energy resource. There are no fuel costs and no harmful polluting gases are produced.
what are some disadvantages of using wind turbines
Wind farms are noisy and may spoil the view for people living near them.
what does a dam do
its holds back large volumes of water
Hot water and steam from deep underground can be used to drive turbines. This is called
geothermal
advantages to geothermal energy
Geothermal energy is a renewable energy resource.
The hot water and steam can be used to heat buildings directly.
