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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

Glass fibers from retired wind turbine blades can be converted into high-capacity silicon-carbon battery anodes, turning a ...
