We know that there is enough wind globally to satisfy much, or even most, of humanity’s energy requirements – if it could be harvested effectively and on a large enough scale. Vertical axis wind turbines (VAWTs), which may be as efficient as current horizontal axis systems, might be , simpler and significantly cheaper to build and maintain…

Informations and news about wind turbines
(Reuters) – The world will have enough wind turbines to generate more than 300 gigawatts of power – the equivalent of 114 nuclear power plants – by the end of the year, industry figures show. As Brazil, China, Mexico and South Africa add turbines, the figure represents modest growth compared with a year ago, when the overall total capacity was just over 280 gigawatts. “Worldwide installed…
There are two types of wind turbines. One is Vertical axis wind turbines and the other is horizontal axis wind turbines.

What is Wind? Wind is simply air in motion. It is caused by the uneven heating of the earth’s surface by radiant energy from the sun. Since the earth’s surface is made of very different types of land and water, it absorbs the sun’s energy at different rates. Water usually does not heat or cool as quickly…
Wind energy is one of the more efficient alternatives to fossil fuel energy. Wind power gives a significant Return On Investment (ROI) since it’s free energy that also has an endless renewable power source. 59% efficiency is the BEST a conventional wind turbine can do in extracting power from the wind. Wind Power depends on: • amount of air (volume)• speed…
