A modern day windmill that is good for the environment and your wallet. Sept. 16, 2010— -- Moving to alternative energy reduces our dependence on foreign oil, but it is not always easy or ...

The awareness of a greener future and its benefits is getting all the right attention in Europe. With the current climate conditions and with energy bills skyrocketing, every other person in the ...

EPFL researchers developed optimal pitch profiles for vertical-axis wind turbines using a genetic learning algorithm. The new pitch profiles resulted in a 200% increase in turbine efficiency and a 77% ...

The world's first offshore wind farm was installed in 1991 off the coast of Vindeby on the Danish island of Lolland. It included 11 turbines with a capacity of 450 kW each, and the project cost 10 ...

Small vertical axis wind turbines (VAWTs) possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban ...

If you’ve got a property with some outdoor space and plenty of wind, you might consider throwing up a windmill to generate some electricity. Indeed, [The Broject List] did just that. Only, his ...

The Eiffel Tower has just unveiled a new, sustainable facelift, and perhaps the most striking update to the famous landmark comes in the form of two of Urban Green Energy’s (UGE) vertical axis wind ...

Windspire's VAWTs individually perform similarly to all vertical axis turbines, at levels of efficiency below that of horizontal-axis wind turbines. They have struggled in the relatively crowded small ...

Researchers at the UK’s Oxford Brookes University think wind turbines would be more efficient if they were designed differently. A team from the School of Engineering, Computing and Mathematics has ...

Think of wind turbines and massive blades spinning above Kansas prairies or off Danish coastlines are probably what comes to mind, but Minnesota-based Janulus has developed something a little more ...

Even as more offshore wind projects launch and the turbines they use get bigger, there are questions around offshore wind’s economic viability. Unsurprisingly, hauling huge equipment with multiple ...

These scale model wind turbines use fixed-pitch blades to evaluate a new vertical axis wind turbine design. Vertical axis wind turbines are easier to install than traditional horizontal axis wind ...
