How much wind power is there roughly in Britain and its surrounding? Given the prominence of the climate crisis, it's important to get some estimates of how much wind power is available in Britain as part of a renewably energised future.
Q. What is yearly average of wind energy available on the landmass on Britain.
And how much does this work per metre squared?
More, given that for some they can be unsightly, how much yearly wind energy is available on the island shelf around Britain, say up to 30 km; and again what is the average per square metre? How does this compare with the yearly energy consumption in Britain?
Thank you.
2.2TWe on average in the seas...
The uk uses less than 350 Gigawatts every year, so the sea can provide about 6 times the current UK energy consumption:
80 GW in shallow waters (0-25 m)
270 GW in seas of depth 25-50m
(up to there is sufficient to meet all of the UK's 2016 energy consumption)... There is also:
790GW in seas of 50-100m
1030GW at 100m-700m

For onshore resources, you can add another 100GWh.
