How Wind Turbines Harm BatsCaitlin Kight
Wind turbines can turn the power of wind into the electricity we all use to power our homes and businesses. They can be stand-alone, supplying just one or a very small number of homes or businesses, or they can be clustered to form part of a wind farm. Here we explain how they work...
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...
Prevention is better than cure, which is why it's best to have the right dry-air strategy for your wind turbine from the very beginning - as soon as the wind turbines leave the manufacturing site. But what if your wind turbines never had the right dry-air strategy from the beginning, ...
Wind turbines that produce enough electricity to fully — or even partially — power a home are substantial in size. Unlike many solar generators and photovoltaic panel systems, you’ll most likely require planning permission and permits to install a wind turbine for residential use — even if it...
Vertical-axis wind turbines (left: Darrieus turbine) In a VAWT, the shaft is mounted on a vertical axis, perpendicular to the ground. VAWTs are always aligned with the wind, unlike their horizontal-axis counterparts, so there's no adjustment necessary when the wind direction changes; but a ...
How does floating offshore wind energy work To find out how floating offshore wind energy works, we must first answer the following question: Why do wind turbines float in the sea as structures 120 metres high and weighing thousands of tons? The solution was given by Archimedes 2,300 years...
Wind turbines in Greece set a national record on September 6, accounting for 81 percent of the country's electricity output. High temperatures, wildfires and flooding pretty much sum up the weather patterns in Greece since the summer. From an unprecedented amount of rain in...
We are talking here about the final position mode, which provides for the safe end position to be approached after the feathering run and thus ensures the safety of the wind turbines before shutdown. This prevents unnecessary fatigue loads from occurring. Conclusion: More functional safety through...
Commercial wind turbines will feature an internal control system that has a number of uses. It has the ability to start the wind turbine when wind speeds are high enough and can also shut down the turbine when wind speeds are too high. ...
