US scientists have identified yet another wonder of that icon of renewable energy, the offshore wind farm: they may result in weakened hurricanes. Turbines in the right place could not just take the heat out of a hurricane, they could reduce the risk of catastrophic flooding as well. The prediction is based entirely on computer simulation: the US so far has just one 30MW commercial wind farm in operation with just five turbines, off the coast of Rhode Island. But the reasoning begins from the basic laws of physics, and the answer delivers yet another argument for investment in renewable sources of energy, if only because the ferocity and destructive power of US hurricanes is set to increase with ever-greater emissions of greenhouse gases from fossil fuel combustion, and consequent ever-greater global warming.

Offshore wind energy is expected to grow twenty-fold in Asia-Pacific over the next decade, potentially driving tens of billions in investment while growth in solar power capacity is set for its first slowdown in a decade this year, according to new research. The region’s offshore wind energy capacity – which refers to the potential power from turbines – will increase to 43 gigawatts by 2027 with China accounting for much of that with forecast growth to 31 gigawatts from just 2 gigawatts last year, according to a report from Wood Mackenzie. “Together with South Korea and Japan, East Asia needs around $37bn in investments to meet the mammoth growth in offshore wind capacity over the next five years,” said Robert Liew, an analyst at the consultancy. Excluding China, Taiwan was poised to become the region’s biggest offshore wind power developer with 8.7 gigawatts of offshore wind capacity expected by 2027, or 20 per cent of the market, as it embarks on a major transition to slash consumption of coal- and nuclear-fuelled energy. Meanwhile, Wood Mackenzie tipped solar energy demand to dip 18 per cent in 2018, amid declining installations in China, India and Japan.

The Cornwall and Isles of Scilly LEP is hoping the region can gain a foothold in an industry worth a potential £30bn in the next 12 years by unveiling a new strategy for offshore wind farms. Last year the world’s first commercial floating offshore windfarm, Hywind, opened in 129m deep water 15 miles off the Aberdeenshire coast, with Cornwall’s LEP developing a floating offshore wind strategy in response. The plans include a pilot floating offshore wind array of around 36MW, followed by pre-commercial arrays of 100MW and then commercial arrays of between 500MW, with an overall target of 1GW by 2030.
