Offshore Wind 'Could be a Bonanza' for UK Says Expert

As the world gathers in Bonn for COP23, the UN's annual climate change conference, Professor Mike Barnes, from The University of Manchester's School of Electrical & Electronic Engineering, outlines why he thinks offshore wind could be a boom industry for the UK.

The UK generates more electricity from offshore wind than any other country in the world with around 5% of our annual electrical energy coming from the sector. This is expected to grow to 10% by 2020. Wind power is also a fundamental part of the Government's decarbonisation targets. Windfarm electricity
