Wind turbines floating miles out to sea could one day provide electricity to our homes, experts believe.
Wales currently meets about 50% of its needs from renewable sources, including solar and wind.
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.
But how big a part could turbines floating off the Welsh coast play?
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.
