The UK has built a huge amount of offshore wind generation - in fact it had the most in the world until quite recently, and is currently second only to China. This just isn't a complete solution because wind is intermittent, and in particular it tends to drop off to nearly nothing during the coldest parts of winter when energy demand is at its highest. All of the solutions to this are about as speculative and questionable as this proposal.
