Could wind power have prevented Fukushima?

The researchers found that offshore turbines could have prevented Fukushima by keeping the cooling systems running and avoiding a meltdown. The team also found that wind farms are not as vulnerable to earthquakes.

“Wind power gives us plentiful clean energy – now we know that it could also make other facilities safer and more reliable,” said Professor Suby Bhattacharya, Chair in Geomechanics.

“The global review finds that greener really is cheaper – thanks to falling construction costs and new ways to reduce wind turbines’ ecological impact,” 

One of the report’s starkest findings was that new wind farms can produce energy much more cheaply than new nuclear power stations. 

The lifetime cost of generating wind power in the UK has fallen dramatically, from £160/MWh to £44/MWh. This includes all the costs of planning, building, operating and decommissioning the wind farm over its entire life. 

By comparison, the UK Government agreed to pay £92.50/MWh for energy produced at Hinkley Point C nuclear power station. 

“What makes wind so attractive is that the fuel is free, and the cost of building turbines is falling,” commented Professor Suby Bhattacharya, Chair in Geomechanics.

“There is enough of it blowing around the world to power the planet 18 times over. Our report shows the industry is ironing out practical challenges and making this green power sustainable, too.”

Although less power is generated in calmer conditions, the electricity generated could be stored in batteries – as planned for the Ishikari project off the coast of Hokkaido, Japan. Or it could be used to produce hydrogen from seawater, giving us the fuel of the future.
