The entire world could be powered by a single offshore, deep sea wind farm, researchers have said – but it’d have to be rather large.
Specifically, it would be the size of India, researchers say – stretching over a million square miles.
Researchers Anna Possner and Ken Caldeira said, ‘On an annual mean basis, the wind power available in the North Atlantic could be sufficient to power the world.’
Wind speeds over the ocean are on average 70% higher than they are on land – and simulations show that large wind farms on sea could generate up to four times as much electricity as wind farms on land (6 watts per square metre as opposed to 1.5).
