Nuclear

Reliable

Lots of  Energy produced from little fuel

No greenhouse gases emitted

Nuclear Waste

Commissioning/Decommissioning costs

1 of 6

Fossil Fuels

Reliable

Lots of energy from little fuel

Gas and Oil are transported easily (not coal)

Coal produces CO2 and SO2 - CLIMATE CHANGE

Gas and Oil don't produce SO2 but still some CO2 (less than coal)

Will eventually run out

2 of 6

Wind and Solar

No Fuel Cost

No CO2 - no Climate Change

Renewable

Unreliable - eg not always sunny or windy

Do not generate much electricity

3 of 6

Water Power

W = Wave // T = Tidal // H = Hydroelectric

W~T~H - No fuel cost

             - No CO2

T~H ~ Very Reliable

       ~ Produce lots of power

W //  Difficult to design to produce enough energy

T //  Damages estuaries/habitats

H //  Damages habitats andthere aren't many suitable sites

4 of 6

Biomass

Inside living things

Carbon neutral

Harmful waste turned into something useful

Land is needed

Very ineffiecient

5 of 6

Geothermal

No fuel cost

No CO2

Very Reliable

Few sites available - ie near a volcano
