Energy Resources
wind power
-
each turbine has a generator inside and the rotating blades turn the generator and produce electricity
there is no pollution, no permanent damage to the landscape as they can be removed, the initial cost are quite high but there are no fuel costs and minimal running costs
they spoil the view, they can be very noisy, don't work if the wind stops (only produce 70-85% of the time)
solar pannels
-
-
-
only produce very hot water in very sunny climates
, although warm water can be produced even on cloudy days solar panels do not work at night
hydroelectric power
-
-
it can provide an immediate response to an increased demand of electricity, is usually very reliable, initial costs are high but no fuel costs and minimal running costs
floods farmland and pushes people from their homes, the rotting vegetation underwater releases methane
tidal barrages
-
as the tide comes in the estuary fills up and water is allowed out through turbines at a controlled speed
there is no pollution, quite reliable, initial costs are high but there are no fuel costs and minimal running costs
prevents access for boats, spoils the view and alters the habitat of wildlife
bio-fuels
-
they can be solid, liquid or gas and are burnt to create electricity
-
cost to refine biofuels is very expensive, species are losing their natural habitats, cannot respond to immediate demands
-
