The O2 Arena will soon use a new breed of “vertical wind turbine” to generate its own clean electricity, after signing a deal with a startup firm that says its turbines will generate power even when the wind is not blowing. The London landmark once known as the Millennium Dome will begin by installing 10 of the 68cm (27in) vertical turbines. The breezy conditions at the site on the River Thames will help generate enough clean electricity to power 23 homes. Although this is a small amount of the O2’s total energy consumption, the arena’s owner, AEG, expects to install more of the mini turbines across its stadiums worldwide. The new breed of turbine is said to be able to spin from even a gentle movement of air, or a passing car. Each unit is made from recycled plastic and weighs about 4kg (9lbs), but the design could be scaled up to help generate as much electricity as 20 sq metres of solar panels, according to its developer, Alpha 311. Lee Lacey, the facility director at the O2, said the arena had “been searching for a suitable wind-generated power source” to help cut its greenhouse gas emissions and reach […]
