Could we see 'floating turbines' thanks to Boris' wind power pledge?
The South West could get 'floating turbines' as the average water depth in our region is below the 60 metre limit needed for traditional offshore windfarms.

That's according to one of the leaders of a South West project, which is trying to increase wind energy production in the West Country.
This week the Prime Minister pledged to create 1GW of floating offshore wind energy by 2050 - and today we're looking at the likely impacts on the region.
Professor Richard Cochrane, Associate Professor in Renewable Energy, at the University of Exeter Penryn Campus said he welcomed the ambition and believed the region would benefit from a Government focus on wind power.
According to a report commissioned by the Cornwall and Isles of Scilly Local Enterprise Partnership, 1GW of floating offshore windfarms in the Celtic Sea could support 3,200 jobs in the South West and Wales and £682m of spend in the local supply chain by 2030, powering hundreds of thousands of homes.
In his speech to the Conservative Party virtual annual conference Boris Johnson pledged to power every home in Britain with offshore wind energy within a decade.
He said: “We will not only build fixed arrays in the sea, we will build windmills that float on the sea – enough to deliver 1GW of energy by 2030, 15 times as much as the rest of the world put together.”
The pledge is being seen as huge boost to floating offshore wind ambitions in Cornwall and the South West, which have been led by the LEP for the last two years. Apart from Scotland, the Celtic Sea is the only other part of the UK where floating wind turbines can be deployed at scale.
And next month will see the formal submission of a Cornwall-led £30m-plus funding bid for Government investment to accelerate the creation of a floating offshore wind industry in the region as part of a £64m project.
The South West Floating Offshore Wind Accelerator project is being led by Wave Hub, the Cornwall Council-owned marine renewables research and technology organisation, in collaboration with the LEP, University of Plymouth, University of Exeter, the Offshore Renewable Energy (ORE) Catapult, A&P Group, Cornwall Council and Plymouth City Council.
It aims to build on Cornwall and Plymouth’s world-renowned excellence in offshore renewables business and research to fast-track the construction of large scale floating offshore windfarms in the Celtic Sea from the mid-2020s onwards.
LEP director Steve Jermy, who is also executive chair of Wave Hub, said: “We’re delighted with the Prime Minister’s support because it recognises the huge contribution floating wind can make to the UK’s renewables targets and the thousands of jobs that would result.
"The deployment of floating wind farms off Cornwall and in the Celtic Sea is something we have been working towards for the last two years. We’ve been able to draw on the county’s unique expertise in offshore renewable energy and we are confident that Cornwall can play a leading role in delivering the Prime Minister’s ambitious vision."
Mr Jermy said plans to sell the Cornwall Council-owned Wave Hub offshore energy test site to a renewable energy project developer by the end of the year meant there could be a floating wind pilot project generating power off the coast of Cornwall as early 2023. And he said there was the ambition in Cornwall to develop 3GW of floating offshore wind energy in the Celtic Sea by 2030.
And as well as floating offshore wind Cornwall is pioneering deep geothermal energy to tap the heat in granite deposits five kilometres beneath the earth, and is looking at how lithium can be extracted from deep geothermal brines for use in battery technology to help drive the electric car revolution.
Last month the LEP announced it was supporting a £4m project to build Europe’s first geothermal lithium recovery pilot plant using investment it has secured from the Government’s Getting Building Fund. The project is a collaboration between Cornish Lithium and Geothermal Engineering Ltd.
