How Do Wind Turbines Work? Rebecca J. Barthelmie and Sara C. Pryor Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally re...

Video: How Eagles Are Making Wind Turbines Safer for BirdsFairchild, Caitlin
Over recent years, it became widely accepted that alternative, renewable energy may come at some risk for wildlife, for example, when wind turbines cause large numbers of bat fatalities. To better assess likely populations effects of wind turbine related wildlife fatalities, we studied the geographic...
Well, let me tell you some practical ways to do it. First of all, we should protect the habitats of wild animals. You know, forests and wetlands are the homes for countless animals. For example, I once went to a forest. It was so beautiful and full of life. There were birds ...
it turns a generator that creates electricity. This conversion from wind to rotational energy to electricity has defined wind turbines since their invention in the late 19th century. And there are three primary factors that determine just how much energy they can produce: the size and orientation ...
In the case of extreme icing, restarting turbines may not be possible for hours and potentially days. The solution is obvious: de-ice the blades, or find a way to keep ice from forming in the first place. So far, however, most of the strategies for k...
17、y. wind direction: this is an "upwind" turbine, so-called because it operates facing into the wind. other turbines are designed to run "downwind," facing away from the wind. wind vane: measures wind direction and communicates with the yaw drive to orient the turbine properly with 18、...
