1.5  A brief summary comparison of advantages and disadvantages of energy resources

(mainly for electricity production)

elecprodseq.gif

Summarises many of the energy resource uses described e.g.

Stage 1 includes fossil fuels, wind, tidal, geothermal, biomass, sunlight, nuclear, hydroelectric.

Stage 2 is often kinetic energy e.g. from very hot moving steam, or cold water/wind flow.

Stage 3 is often a turbine driven by steam of wind.

Stage 4 is usually an electrical generator.

ENERGY RESOURCE for heat or electricity Examples of ADVANTAGES Examples of DISADVANTAGES
COAL from the remains of buried and decayed plant remains relatively cheap, suitable for big power big stations very polluting from smog and acid rain, non-renewable fossil fuel (115 years left?), carbon dioxide produced
BIOMASS from plant growth e.g. oils, sugar, wood or from animal dung renewable from plant and animal resources, can use waste material, less demand on non-renewable resources pollution can be high but does recycle carbon dioxide, no good for big power stations
WIND, the heat from Sun warms air, causes movement renewable, no fuel costs, little pollution, less demand on non-renewable sources, no carbon dioxide produced unreliable due to variable wind speed, no good large scale
SUNLIGHT infrared radiation for heat renewable, no fuel costs, little pollution, less demand on non-renewable resources, no carbon dioxide produced unreliable due to variable sunlight intensity
ENERGY RESOURCE for heat or electricity Examples of ADVANTAGES Examples of DISADVANTAGES
NATURAL GAS from the remains of buried and decayed marine organisms reasonably cheap for medium to large scale power stations, quick start up, efficient, convenient to pipe  medium pollution, carbon dioxide adds to global warming, non-renewable (90 years left?)
SUNLIGHT for electricity directly using visible light sensitive solar cells renewable, no fuel costs, no pollution, less demand on non-renewable resources, good for remote locations unreliable, no good for large scale power
NUCLEAR power from unstable atoms disintegrating suitable for large scale power stations, no carbon dioxide to add to global warming toxic radioactive waste, accidents potentially very serious, very costly to build and dismantle, non-renewable
HYDROELECTRIC power from rainwater stored behind dam renewable, no fuel costs, no pollution, no demand on non-renewable resources, fast start up and increase power, no carbon dioxide produced very costly to build, disruption or removal of wildlife habitat or farmland, limited suitable valley locations
ENERGY RESOURCE for heat or electricity Examples of ADVANTAGES Examples of DISADVANTAGES
WAVE POWER from the up-down movement due to wind renewable, no fuel costs, no pollution, no demand on non-renewable resources unreliable, storm damage
CRUDE OIL from the remains of buried and decayed marine organismslots of it at the moment, relatively cheap, ok for big power big stations, easy to pipe around polluting from smog and acid rain, non-renewable fossil fuel (80 years left?), adds to global warming
TIDAL BARRAGE from the mass movement of water due to gravity pull of the moon renewable, no fuel costs, little pollution, less demand on non-renewable resources, no carbon dioxide produced very costly to build, disruption of wildlife habitat, limited suitable estuary locations, cannot generate power when tides are turning (about 10 useful hours?)
GEOTHERMAL from hot rocks underground in active/recent volcanic regions renewable energy resource, no fuel costs, little pollution, no carbon dioxide limited suitable locations
