Renewable?
Uses
Power output
Environmental impact
Fossil fuels (oil, coal and natural gases)
Chemical
Non-renewable
Transport, heating, electricity generation
High
Releases carbon dioxide (causes global warming)
Nuclear fuels
Nuclear
Non-renewable
Electricity generation
Very high
Radioactive waste (needs to be disposed of safely)
Bio-fuel
Chemical
Renewable
Transport, heating, electricity generation
Medium
'Carbon neutral', so low impact
Wind
Kinetic
Renewable
Electricity generation
Very low
Takes up large areas that could be used for farming, some people say windmills spoil the view
Hydroelectricity
Gravitational potential
Renewable
Electricity generation
Medium
Local habitats are affected by the large areas that need to be flooded to build dams
Geothermal
Internal (thermal)
Renewable
Electricity generation, heating
Medium
Very low
Tides
Kinetic
Renewable
Electricity generation
Potentially very high, but hard to harness
Tidal barrages can block sewage which needs to go out to sea
Sun
Nuclear
Renewable
Electricity generation, heating
Dependent on the weather and only available during daylight
Very little
Water waves
Kinetic
Renewable
Electricity generation
Low
Very low
