Dutch Windwheel draws energy innovations
Vulnerable grassland birds abandon mating sites near wind turbines
Shifting to renewable energy sources has been widely touted as one of the best ways to fight climate change, but even renewable energy can have a downside, as in the case of wind turbines' effects on bird ...
Floating wind turbines bring electricity where it's needed
It's a balloon that lifts a wind turbine. That's the easiest way to describe the technology being developed by Altaeros Energies, led by Ben Glass, inventor and CEO of the young company. Glass has reimagined ...
Engineers study the benefits of adding a second, smaller rotor to wind turbines
