Coal

Wind Power
Nuclear Power
Coal is used to produce steam that drives a stream turbine
As it is known, this produces high levels of carbon dioxide and this contributes to the greenhouse effect
Most common method of electricity generation
The waters kinetic energy is used to turn the turbine, which then produces electricity
Has large impacts on the environment as it involves damming and diverting of rivers
Uses water held in dams above the power station
Only possible in mountainous regions
Generates electricity without atmospheric pollution
It is ‘clean’ for the environment, but would be required in large numbers in order to power large towns and cities
Large tracts of land are needed for these projects
The turbine drives a generator and electricity is produced
Causes noise pollution to neighbouring citizens
Uses wind to drive the turbine
Does not pollute the atmosphere
The by-products of nuclear power are a problem as they are contaminated for thousands of years
Uses heat from a nuclear reaction to turn a turbine
