Fuel type
hydroelectric power
At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine that spin to power a generator to produce electricity

disadvantiges
Building of dams impacts the natural flow of water
Villages and ecosystems may be destroyed when dams and reservoirs are built
geothermal power
Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.

biofuels
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial biowaste.[1] Biofuels are mostly used for transportation, but can also be used for heating and electricity.
advantiges
A renewable source: bioethanol and wood are both obtained from growing plants, biogas from the recycling of waste products

tidal power
Tidal energy is a form of power produced by the natural rise and fall of tides caused by the gravitational interaction between Earth, the sun, and the moon.

-
nuclear power
Nuclear power reactors use heat produced during atomic fission to boil water and produce pressurized steam. The steam is routed through the reactor steam system to spin large turbines blades that drive magnetic generators to produce electricity.
-
fossil fuels
Fossil fuels are made from decomposing plants and animals. These fuels are found in Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.
