Vancouver—Western Wind Energy Corp (“Western Wind Energy”) is pleased to announce that it has purchased 120 megawatts of Gamesa G8X Series wind turbines.
Gamesa, a world-leading player in the design, manufacture and maintenance of wind turbines, has been awarded a contract to supply a total of 120 MW of capacity to the Windstar wind project, which is being developed by Western Wind Energy Corporation at the Tehachapi Pass in southern California.
It will be the largest wind farm developed to date in the United States by Vancouver, Canada-based Western Wind Energy and also Gamesa’s first contract with this developer, which has wind power projects in California, Arizona and Ontario.
You know how leaves flutter in the wind? What if there were a device that could harness the energy of hundreds of leaves via the piezoelectric technology that converts movement or pressure into electricity? A “tree” made of such leaves could be installed in urban settings to generate electricity, without upsetting the neighbors or violating community aesthetic codes.
Richard Dickson is developing such a system and has filed a patent on the same. His passive wind harvesting technology that uses *PVDF and piezoelectric ceramics materials woven into textile-like material to form artificial leaves for a bio-mimicking “tree”.
* PVDF = polyvinyl material that generates piezoelectricity…originally developed for NASA.

Sustainable energy is the renewable energy which is not expected to be exhausted in a timeframe and its sources are not supposed to be consumed ever. The sources of the sustainable energy are natural like solar power hydro power wind power bio fuel biomass geothermal power and so on. Sustainable energy is also the alternative of the fossil energy. The sources of the renewable energy are inexhaustible.
Increasing the use of sustainable or renewable energy decrease the use of fossil fuel resources and increase the contribution of world energy security. When the fossil energy resources are consumed the emission from these are causing the pollution. In this current scenario one of the biggest social problems is pollution. To prevent the alarming growth of the environment pollution it becomes very necessary to use the sustainable energies instead of the fossil energy. And how is that you are using the energy as much as you require and that doesn’t create any pollution. Keeping the earth a healthy clean and clear!
Wind energy releases no pollution into the air or water, and does not contribute to global warming. According to the American Wind Energy Association, “on average, each MWh of electricity generated in the U.S. results in the emission of 1,341 pounds of carbon dioxide (CO2), 7.5 pounds of sulfur dioxide (SO2) and 3.55 pounds of nitrogen oxides (NOx). Thus the 10 million MWh of electricity generated annually by U.S. wind farms represents about 6.7 million tons in avoided CO2 emissions, 37,500 tons of SO2 and 17,750 tons of NOx. This avoided CO2 equals over 1.8 million tons of carbon, enough to fill 180 trains, each 100 cars long, with each car holding 100 tons of carbon every year.” And unlike most other electricity sources, wind turbines do not consume water.
Wind power is a free and inexhaustible (“renewable”) source of energy. Unlike fossil fuels such as coal and oil, which exist in a finite supply and which must be extracted from the earth at great environmental cost, wind turbines harness a boundless supply of kinetic energy in the form of wind.
Renewable Energy Jobs: The Jobs of Tomorrow Renewable energy jobs are here to stay!
Renewable energy careers are increasing in number daily not just in the United States, but around the world as the dedication strengthens to move toward a sustainable energy future.
To make this happen, workers will be needed to build, maintain and manage the companies that will be expanding into the renewable energy field. This is exciting news for you and me!
How It Works
There are several ways to use the sun’s power to generate electricity. One of the most promising is called concentrating solar power. This involves using mirrors to reflect and focus the sun’s rays, providing heat, which in turn helps power a generator. Another is photovoltaic panels, such as the displays on the rooftops of homes and office buildings (some of these displays, especially in California, have recently experienced problems with theft).
Drawbacks and Incentives
We have obviously come a long way from the traditional windmills of the yesteryears – which were primarily used to grind corn, to the state-of-the-art wind turbines – with the sole purpose of generating electricity, that have been introduced of late. Amidst all the chaos surrounding the use of fossil fuels and pollution that they cause, wind energy come up as one of the apt alternative source of energy today. In fact, many people are of the opinion that wind power has the ability of replacing fossil fuels for electricity generation in the future. In a bid to see whether this claim really holds ground, we decided to evaluate some wind power facts and asses its feasibility with the intention of finding out how efficient wind power is. As you move on with the following information on efficiency of wind generators or wind turbines, you will be in a better position to take a stand on the development of wind power.
How Efficient is Wind Energy?
Back in 1919, Albert Betz – a German physicist, revealed that the maximum possible output for wind turbines is 59 percent. In what is referred to as the Betz’s law, he states that the maximum possible energy that can be derived from a hydraulic wind engine or a wind turbine is 16/27 i.e. 59 percent of the total kinetic energy of wind. However, any wind farm which boasts of an efficiency of 30 percent is considered efficient today. You may also come across sources – most of which happen to be wind turbine companies, which state that the modern wind turbines have the capacity of generation 70-80 percent electricity. The fact is that ideally even modern wind turbines can only produce 20-40 percent electricity – depending on several underlying factors, at the max. The fact that a power source with an efficiency of mere 30 percent is being pitched as a power source of the future will no doubt come as a surprise for many. In order to understand the intricacies of the entire matter, we need to go through the basics of wind power generation – right from how wind energy is converted into electricity.
The July issue of Bonnierâs Popular Science features a 3D cover that allows readers to log onto the magazineâs Web site and interact with an animated “hologram.”
When a reader logs onto popsci.com/imagination and holds the cover to a Web camera, an interactive image featuring wind turbines appears on the computer screen. Once the image is activated, the user can cause the blades to begin turning by blowing air onto the webcam microphone.
Pickens unveiled plans in 2007 for the 4,000-megawatt wind farm — big enough to power 1.3 million homes — at a projected cost of $10 billion. In May 2008, Pickens ordered 667 wind turbines from General Electric for the first of four project phases. Mesa is scheduled to begin taking delivery in 2011.
The project was a symbol of the oilman’s commitment to his high-profile campaign to slash the nation’s dependence on foreign oil with a combination of wind power and the use of natural gas in vehicles.
