Powering all UK homes via offshore wind by 2030 'will need £50bn'

Aurora Energy Research calculates investment would have to quadruple capacity

Boris Johnson's bold new vision for offshore wind to power every home in the UK by 2030 would require almost 50bn in investment and the equivalent of one turbine to be installed every weekday for the whole of the next decade.

The huge investment, calculated by Aurora Energy Research, an Oxford-based consultancy, would increase the UK's offshore wind power capacity by four times what it is today, to reach 40GW by 2030.
