It’s the new Aerogenerator X Vertical Axis Wind Turbine, which will be completed by 2014. Instead of using a traditional vertical structure, this wind turbine will rotate horizontally. Its design will enable it to generate twice the power of previous designs, according to the manufacturer. That’s 10 megawatts per hour. The most powerful—and largest turbine in the planet at 413-foot high—now generates a bit over seven megawatts.
