Methods of generating electricity
Wind power
has been used for centuries in the form of windmills
power wind rotates propellers
turn a drive shaft connected to the turbines
Water power
has a long history as we can see from watermills
nowadays we build a dam to increase the power of rivers to turn turbines
hydro-electric stations
Steam power
most practical and widespread for generating electricity
boiling water to produced high-pressure steam there are more variety of ways
Burning fossil fuel
Heat water in a boiler, Coal, oil and natural gas is the fossil fuel
they formed form the remains of plants and animals died
extraced through mini or drilling
Solar power
create heat to boil water by using system of mirrors
to focus, ray of the sun onto a solar furnace
Biomass
is fuel from of wood or other plants
produced through agriculture or forestry
can be burned to heat water and create steam
burn household rubbish and other forms of waste material
Nuclear fission
is a process which atoms of uranium or plutonium are split
releases an enormous amount of heat
can be controlled to produce steam and thus electricity
Geothermal energy
present under surface of the earth
drill deep holes and then pipe water down to be heated by the hot rocks
