With over 350,000 wind turbines currently in use globally, wind continues to be one of the fastest growing forms of renewable energy. In 2021, 93.6 GW of new installations brought global cumulative ...

A short video from the U.S. Department of Energy illustrates how the 130' long blades of wind turbines generate power. Trying to build a better planet. Read more from this special report. Shaped a ...

The towering structures are often taller than the Statue of Liberty and can adjust to changes in the wind to maximize energy generation. Wind turbines are a modern marvel, harnessing the power of the ...

A new model accurately represents the airflow around rotors, even under extreme conditions. The first comprehensive model of rotor aerodynamics could improve the way turbine blades and wind farms are ...

Wind energy harnesses atmospheric air movement driven ultimately by solar heating. Uneven heating of Earth's surface, land warming and cooling faster than oceans, intense solar radiation at the ...

The blades of propellers and wind turbines are designed based on aerodynamics principles that were first described mathematically more than a century ago. But engineers have long realized that these ...

For years now, the U.S. Department of Energy has had one major roadblock to the streamlining of wind turbine installation: the sheer amount of work it takes to manufacture blades. Thanks to 3D ...

・Bladeless wind turbines use a swaying mast instead of spinning blades, which could suit locations where conventional turbines are impractical. ・Computer simulations found that mast length and width ...

For the first time, engineers at MIT have developed a comprehensive, physics-based model that accurately represents the airflow around rotors even under extreme conditions. The new model enables the ...
