RENEWABLE / ALTERNATIVE ENERGY
Solar
advantages
potentially infinite energy supply
single dwellings can have own electricity supply
maintenance and upkeep costs are low
disadvantages
manufacture and implementation of solar panels can be costly
energy is only supplied during the daytime and when there is enough sun
energy can be stored but this is expensive
solar farms can take up large areas of land
Wind
Advantages
potentially infinite energy supply
versatile in terms of size and number of turbines
can supply energy to rural areas that are not connected to electricity grid
Disadvantages
manufacture and implementation of wind farms can be costly
some local people object to on-shore wind farms, arguing that it spoils the countryside
some argue wind farms are dangerous for birds and other wildlife
wind is an unreliable source of constant energy
Tidal
Tidal energy comes from
the movement of tides driving turbines
Advantages
ideal for an island such as the UK
potential to generate a lot of energy
tidal barrage can double as a bridge,
and help prevent flooding
Disadvantages
construction of barrage is very costly
only a few estuaries are suitable
opposed by some environmental
groups as having a negative impact on wildlife
may reduce tidal flow and
impede flow of sewage out to sea
Wave
Advantages
ideal for an island country
Disadvantages
.
costly
.
may be opposed by local
or environmental groups
Geothermal
In volcanic regions it is possible
to use the natural heat of the Earth
Advantages
potentially infinite energy supply
Disadvantages
can be expensive to set up and only
works in areas of volcanic activity
geothermal and volcanic activity might calm
down over time, leaving power stations redundant
dangerous elements found
underground must be disposed of carefully
