Prime Minister Boris Johnson wants to see fixed offshore wind farms power UK homes by 2030, while Plaid Cymru believes Wales could be self-sustainable through renewables by then.

A 96 megawatt (MW) wind farm capable of powering 90,000 homes is proposed for an area of sea 28 miles (45km) off Pembrokeshire by 2027.

However, this could be just the tip of the iceberg, in light of other developments.

Successful trials in Scotland suggest floating turbines could have advantages over other types of renewables, including cost and environmental impact.
