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 ...

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 ...

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 ...

Are we stuck in a rut when it comes to wind turbine design? For decades, horizontal axis wind turbines (HAWTs) have dominated the renewable energy landscape, towering over fields and oceans as the ...

The Belgian start-up Philéole has developed a vertical-axis wind turbine for sailboats that captures air currents from all directions while sailing, thereby generating electricity for the onboard ...

Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been ...
