The first commercial offshore wind turbine that Siemens created 30 years ago had 5-metre long blades and produced a paltry 30kW. A lot can change over three decades. The company's newest offshore model isn't just the biggest in the sea; it's the biggest anywhere. Read More >>

We've yet to discover a perfect source of clean energy, and while wind turbines come close, many people still consider them to be an eyesore. But we don't think anyone would complain if they all featured the beautiful spinning helix design of the Hercules turbine. Read More >>

We recently caught wind of the high-flying turbine blimps that could cut our energy costs by up to 65 per cent. Now we get to see a prototype of this glorious feat of human engineering in action. This is not science fiction; the future is here. Read More >>

Wind blows stronger and more consistently as you rise above ground obstacles like buildings, trees, and hills. This makes for a lucrative green energy source—assuming you can lift generators 1000 feet in the air. This Airborne Wind Turbine could well become the first. Read More >>
