External Company Press Release The UK has the largest wind farm market, beating other world leaders such as Germany and China - so much so, that 20% of the UK's energy comes from wind turbines. However, there is currently an even bigger drive to increase wind energy use in Europe. With Boris Johnson's pledge to quadruple offshore wind power by 2030, to 40GW - enough to power every UK home - the drive for more renewable energy sources to power our everyday lives has never been stronger. But, powering a capital, such as London, is easier said than done, as it would need nearly 1,500 wing turbines according to new research from Uswitch.com, the comparison and switching service.
