Pros and cons of renewable energy resources

Advantages of non-renewable energy resources

Most renewable energy resources are clean, because they do not produce any pollution and cheap because their energy supplies do not have any cost.

Hydroelectric power stations, as well as tidal and wave generators, are very reliable, and both hydroelectric power stations and tidal generators produce large amounts of electricity.

Disadvantages of renewable energy resources

At the present time, most renewable energy generators are expensive to set up. Also, sources such as wind turbines and solar cells rely heavily on the weather. If it is not a windy day, wind turbines will not turn. And if it is not sunny, solar cells will not produce much electricity.

Energy ResourceAdvantagesDisadvantages
Fossil fuelsReliableCreate pollution and will run out
Nuclear powerReliableWill run out and produce dangerous waste that is hard to dispose of
Wind turbinesClean and cheap to runExpensive to set up and wind does not always blow
Wave generatorsClean and cheap to run and Scotland has a lot of coastlineExpensive to set up
Tidal generatorsClean and cheap to run and produce a lot of electricity once runningVery expensive to set up and could be hazardous to local wildlife
Hydroelectric power stationsClean and cheap to runExpensive to set up and output could be affected by drought
Solar cellsClean and cheap to runNot always sunny and output does not always outweigh initial cost to set up
