Wind turbines at Dagenham’s Ford site produced enough electricity to power 2,500 homes last year.

The 80 metre-high structures – the first turbines in the whole of London – generated just under 10 million units (kWh) of electricity in 2013, enough to brew 352,062,678 cups of tea or keep an iPad going for almost 586,771 years.

Owned by green energy supplier Ecotricity, the first two turbines were installed in 2004 before a third was added seven years later.

The windmills generate electricity directly for the Ford’s diesel engine assembly plant and save about 5,000 tonnes of CO2 from entering the atmosphere each year.

Nick Osbourne, spokesperson for Ecotricity, said: “Last year was a big 12 months for wind energy in the UK, and the significant output from the three turbines at Ford is further evidence of that.

“Merchant wind turbines like these play a big part in cutting the emissions that cause climate change.”

2013 was a momentous year across the UK with wind power producing over 6.1 GW of energy at peak in one day in December - a British record.
