The urban wind power revolution is underway. It’s called a RidgeBlade and it’s just had a real seal of approval - it won first prize at a recent Dutch event called the Picnic Green Challenge. The RidgeBlade is an unobtrusive wind turbine that sits on rooftops anywhere, able to generate electricity even when the wind is hardly blowing.

Earth Beat caught up with the inventor, a rather stunned Dean Gregory from the Power Collective who was holding, literally and figuratively, a massive cheque for half a million euros.
 
"It's designed to be a very affordable, very effective and very easy-on-the-eye form of wind generation," says Dean Gregory. Anyone with a pitched roof can use one, and "it will generate electricity, save carbon emissions, and hopefully it will earn them money."
 
With the prize money going directly into production, the RidgeBlade could adorning rooftops near you by the end of next year.
