The Wind Energy Industry is Nothing New

Chinese Windmill Though our scientists may claim that they are inventing something new by using wind as a source of generating energy, the truth is that wind is being used for centuries for this purpose. An example of this is an article published in 1838, which clearly shows that even in those times, wind was considered an important source of energy. Here are a few quotes that were recorded in the past, which prove that wind was always important in generating energy. View Comments

Fresh-Water Wind Farm on Lake Erie

Wind Farm on Lake Erie A fresh-water wind farm is taking shape at Lake Erie and when completed will provide 20 megawatts and get on to about one gigawatt power by 2020. Huge individual turbines 300 feet tall, to be built by GE will be erected off Ohio, Cleveland. Better designs: These are special gearless super-efficient turbines, with three 176-foot long blades, which run with the help of a giant ring of magnets. The blades are longer due to strategically placed carbon fibre, and lighter too. Many moving parts like gearbox, coils and starter brushes are eliminated with resultant reduced maintenance. The giant magnetic ring array helps the turbine generate power even at very low speed. Rejuvenating wind energy industry: As land-based turbines are facing a lack of interest and demand, wind energy industry is facing a setback. This new-design turbines to tap ... View Comments

Two Wind Farms get Investment from Google

Google Wind Farms Now big companies are going green and proudly proclaiming it too from rooftops. Google Inc. has invested $38.8 million in two North Dakota wind farms. This is the first direct investment by Google in utility-scale renewable energy generation. These two wind farms produce 169.5 megawatts of power. These two wind farms can light up around 55,000 homes. These wind farms are designed by General Electric Co and created by NextEra Energy Resources. They generate power from one of the world's richest wind resources in the North Dakota plains. There is no need to lay down extra infrastructure for the two wind farms. Current transmission facilities are able to transmit power to the nearby areas. Google's official blog claims, "Through this $38.8 million investment, we're aiming to accelerate the deployment of renewable energy — in a way that makes good business sense, too." View Comments

Is It Possible To Convert To 100% Wind Power?

Wind Power With all the talk of going green, the question had been thrown out many times if there will ever be a time that we can use nothing but renewable energy to power our world. A small island in Denmark is trying answer that question with a resounding yes as they power up every single day via nothing but wind power. The Danish island is the ideal setting as the wind literally never stops blowing. The North Sea offers the perfect opportunity to capitalize on the winds that come off of the sea and for them to use wind power as their primary source of power. As a matter of fact, the wind power that they are using is their ONLY source of power. View Comments

Studying Sea Waves with Radar

Sea Wave Radar Off shore wind is steady and blows harder. If a country is densely populated it is hard to find open space to install wind farms. That is why there are more and more offshore wind farms in densely populated Europe where there is limited space on land and relatively large offshore areas with shallow water. Scientists of the Geesthacht GKSS Research Centre are interested in offshore winds and mechanics of sea waves. They are working on a radar system to study the behavior of the sea waves. This technology will be available for utilization on the North Sea on the FINO3 research platform. This technology will help in finding out the details of the interactions between offshore wind power machines and swells. View Comments

Africa’s biggest wind farm coming up in Kenya

Africa Wind Farm Some of the African regions are so hot that unless you're are accustomed to that climate it is not possible for your to survive. Extreme temperatures also generate extreme winds and perhaps this is the reason wind farms have great potential in Africa. Some 365 giant wind turbines will be installed in desert around Lake Turkana in northern Kenya to create the biggest wind farm in Africa. Once completed -- tentatively in 2012 -- the £533m project, backed by the African Development Bank, will have a capacity of 300MW, a quarter of Kenya's current installed power and one of the highest proportions of wind energy to be fed in a national grid anywhere in the world.
