Wind energy is becoming highly popular in the area of renewable energy, with wind energy being forecast to provide up to 8% of the world’s consumption of electricity by 2021. Advancements in wind ...

A wildly innovative turbine that could halve the cost of offshore wind is set to go into testing in Norway. The 19-m (62-ft), 30-kW, contra-rotating vertical-axis turbine is a prototype of a design ...

Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...

There are several operational factors and requirements that have guided design and development of composite wind turbine blades over the last 20 years. The most important factors and requirements are ...

Wind power generation in the U.S. is enjoying favorable winds. First, the cost of wind turbine installations has dropped by over one-third since 2010 as the capacity of turbines increased. Next, ...

Drag-based wind energy design. Aiming to translate its expertise in manufacturing monocoque, ribbed components with thermoplastic microspheres, Xenecore is working to develop a fan-shaped, drag-based ...

Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more ...

SANY Renewable Energy, a wind turbine manufacturer in China, has built the world’s longest onshore wind turbine blade. The SY1310A is 430 feet (131 meters) long and rolled off the assembly line on ...

Everyone’s owned a pinwheel at one time or another. I remember riding in the back of my parents’ car, sticking my pinwheel out the window as we traveled down the street. The speed at which the ...
