Not surprisingly, higher-speed winds cause wind turbines to rotate very quickly. However, many people are shocked by how fast the tips of utility-scale wind turbine blades move, especially if they...

Wind turbine blades have a difficult job with some very harsh working conditions on earth. They must be stiff and strong enough to withstand the elements day in and day out. Yet, they also need to be...
As the world seeks cleaner sources of electricity, renewable energy is heralded for not burning fossil fuels to produce energy. For example, solar panels use sunlight to generate electricity, while...
One common design element among horizontal-axis wind turbines is that they virtually always have three blades. But how do wind turbine engineers decide to use three blades, and not two or even four...
The number of turbines on a wind farm depends primarily on the amount of available land. A small wind farm may have just a few wind turbines, while a large wind farm can have hundreds or even...
Wind turbines are getting larger, and many turbines installed in 1990s are now coming to end of life. Many people are starting to wonder if they can be recycled.
