Renewable energy resources
Solar: from sunlight is captured in solar panels and converted into electricity
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
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
more likely to be small local operations, rather than done on a national scale
Disadvantages
construction can be costly
may be opposed by local or environmental groups.
