Explain what is meant by the term renewable.
Give an example of a renewable energy source.
Large offshore wind farms are often constructed many kilometres out at sea to harness strong, consistent winds and generate electricity for the National Grid.

Some environmentalists support the expansion of offshore wind power, while others express concerns.
Discuss the advantages and disadvantages of building more offshore wind farms.
