Renewables
- Solar
- the sun generates energy via nuclear fusion
- used to heat water or air
which can be then pumped
around buildings
- converted directly
into electricity by
photovoltaic cells
- the sun generates energy via nuclear fusion
- Biomass
- uses organic matter such as wood and crops
- energy is released by combustion
- energy is released by fermentation to
produce alcohols which can be mixed
with petrol
- energy is released by
anaerobic digestion to
produce biogas which
can be burned
- uses organic matter such as wood and crops
- Wind
- wind turbines convert the KE of the
wind into electrical energy
- wind turbines convert the KE of the
wind into electrical energy
- Wave
- the potential energy of the
difference in height between the
crest and trough of a wave is
converted into KE for turning a
turbine to generate electricity
- the potential energy of the
difference in height between the
crest and trough of a wave is
converted into KE for turning a
turbine to generate electricity
- Hydroelectric
- when rain falls on high land the water has PE. As
the water falls downhill, this is converted into KE
which can be used to turn turbines to generate
electricity- Three Gorges Dam in China

- Tidal
- This gravitational attraction of the
moon and sun causes the tides to
rise and fall. water held behind a
barrage at high tide can be allowed
to run back into the sea as the tide
falls, turning turbines as it goes

- Geothermal
- Rocks deep underground contain elements that
are radioactively decaying which heats rocks and
turns underground rock into steam which can turn
turbines for electricity generation
