Resource summary
Energy resources
Renewable
Hydro-electric
Fast flowing water(waterfall, river)
Its use is widespread
Advantages
One of the cheapest ways
Continuous generation of electricity
Without pollution
Water isn't consumed or contaminated
Disadvantages
Construction is expensive
Away from where people live
Natural vegetation is destroyed
People living close are forced to move
Essential conditions
High rainfall
Natural store of water
Narrow deep valley suitable for building a dam
Geothermal
Heat from the ground in areas of volcanic activity
Solar
Heat from the light of the sun
Solar panels and photovoltaic cells are used
More expensive than wind power
Wave
Force of sea waves
Least used as technology is difficult to develop
Wind
Turbines driven by the force of the wind
Essential conditions
Strong winds are frequent
On hill tops and other areas of open high ground
Along the coastline
Offshore but close to the coast
Advantages
Cheap
Pollution free
Take up little land
Disadvantages
Construction costs are high
Winds need to be constant
Backup is necessary
Eye-sore
Biomass
Using fuelwood, crop waste and animal dung
Non- renewable
Coal
Rotten vegetation formed thick layers of peat that hardened over time
Extracted through mining
Cannot be mined deep as higher temperatures deep underground may cause combustion
Petroleum and natural gas
Decomposition of plants and dead sea creatures
Drilling is the method used for extraction; oil and gas is forced out through pipes
Oil and gas rise to the top of porous rock and are trapped by the impervious rock above
Nuclear power
Fission:An atom containing a nucleus is split using uranium as a reactor
Great deal of heat is released due to fission
This heat is harnessed to make energy
