Diapositiva 3
hydroelectric- renewable
advantages- does not produce CO2-can respond to local needs for electricitydams can store water
disadvantage- dams are expensive to build-there are not many available in "high" places in the UK
Diapositiva 4
wave energy- renewable
advantagesit is more predictable than windit does not produce CO2 or green house gases
disadvantagesequipment can be damaged in stormshigh maintenance out at seanot enough output for many towns
Diapositiva 5
Tidal power- renewable
advantagestides are predictabledoes not produce CO2 or other GHGit needs no fuel
disadvantagesexpensive to buildpower only produced when the tide has come in
Diapositiva 6
wind- renewable
advantagesrunning costs lowdoes not produce CO2 or GHG
disadvantagesunpredictable cannot be controlledcan only be built in certain areas
Diapositiva 7
geothermal- renewable
advantagesdoes not produce CO2 or GHGlow running costs
disadvantagesdifficult to find sites ( needs hot rocks)needs careful managment
Diapositiva 8
solar heating- renewable
Acan be used to produce electricity in remote placesdoes not produce CO2 and GHG
D can be expensive does not work at night
Diapositiva 9
solar cells- renewable
A water is heated without use of electricitycan provide hot water to remote places
Dneeds large roof spacecannot meet the needs of intensive activity/ people
Diapositiva 10
nuclear power- non/renewable
Auranium is readily availabledoes not produce CO2 or GHGefficient
Bwaste needs careful and expensive reprocessingcannot be switched on or off easilypeople object to them being built
Diapositiva 11
bio fuels- renewable
Ait is carbon neutralcan be built on a small scalegood for recycling waste
Bif it is built on large scale it is expensivecan produce unpleasant smellsbiofuel NEEDED for cards
