B. Wind turbines can only work in strong winds, so their contribution to climate change is limited. C. Wind turbines generate electricity without burning fossil fuels, reducing carbon dioxide emissions. D. Wind turbines are too noisy and are not suitable for large - scale construction, so they...
People have also invented quieter ways of hammering in the giant posts needed for giant wind turbines, like this one, and gentler ways of doing seismic surveys. And there are some incentives for using quieter technologies. The European Union, for example, has a healthy marine system directive ...
Modern Wind-power Technology When you talk about modern wind turbines, you're looking at two primary designs: horizontal-axis and vertical-axis. Vertical-axis wind turbines (VAWTs) are pretty rare. The only one currently in commercial production is the Darrieus turbine, which looks kind of li...

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 ...
Since the plane of rotation of the propellers in typical wind turbines is perpendicular to the position of the electric generator, they are initially inconvenient to transport and store once assembled, even when small. I also didn't want to have to use tools to mount and dismount the blades ...
whine would cause unpleasant noise and vibration to the driver. However, reducing unwanted motor noise is by no means limited to electric traction motors. In many other motor applications such as industrial drives, HVACs and wind turbines, reducing motor noise and vibration are important design ...
There are eddy current brakes in wind turbines. They're better at braking the rotors at high speeds and easier to maintain (wind turbines are often in inaccessible places where friction brakes would be too hard to service or repair). You'll also find eddy current brakes in all kinds of ...
Wind turbines, the primary components ofwind powergeneration, can be noisy, obstruct sunlight, produce flickering lights, and disrupt scenic views. These concerns can lead to conflicts between renewable energy development and environmental preservation, potentially exacerbating existing social inequalities. A...
