Taking control of CO2

It was when the world’s leading industrial nations signed up to an agreement that aimed to cut their greenhouse gas emissions by 5% on 1990 levels by 2008-2012. Just between the opposing coastlines of Essex and Kent stands London Array the biggest wind farm in the world. Spreading over 100km2 its 175 turbines generate enough power for nearly half a million homes a year. In fact, December 2015 saw London Array generate a record 369,000 MWh of electricity – considerably above target. Average wind speeds of 27mph were undoubtedly the source of that amazing number. Everything about the wind farm is huge. It has its own offshore and onshore substations. It requires 450km of offshore cabling to get all that power generated by its mighty turbines back to the UK. But the big number that really counts is that London Array reduces harmful carbon dioxide emissions by more than 925,000 tonnes a year. E.ON has been the single biggest partner in London Array right from the very beginning of the project in 2011.
