  • 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
  • Renewable energy production and demand growth is gaining momentum in many ways across the world. There is a booming demand of wind power today and all wind energy equipment manufacturers are gearing up to meet the demand and take advantage of it. Wind power capacity growth will be reaching 447GW in the next five years and by year 2014 end, Asia will lead the world in installed wind capacity.
  • Yes, the day is not far off when reaching for sky is the new motto for generating cost-effective renewable energy. Initially it was considered to be technically non-viable to tap high-altitude winds. But today, technically-advanced materials and innovative computer know-how are giving new life to this scheme with innovative autonomous aerial structures using wind energy to generate power

  • It's an expert estimation that the total energy stored in wind is 100 times higher than actually needed by humans on this earth. The catch is that we have to learn and devise ways to trap this wind power blowing across the planet earth. Experts tell us one more thing that most of the wind energy is available at high altitude and we can’t manufacture turbines of that height. So we have to think of new ways to trap that wind power blowing at a significant height. Some experts estimate that the total energy contained in wind is 100 times the amount needed by everyone on the planet. However, most of this energy is at high altitudes, far beyond the reach of any wind turbine.
  • A research company in New Hampshire recently patented its bladeless wind turbine, which is based on a patent issued to Nikola Tesla in 1913. This wind turbine is christened as the Fuller Wind Turbine. This turbine is developed by Solar Aero. The specialty of Fuller Wind Turbine is it has only one rotating part, known as the turbine-driveshaft. The entire machinery is assembled inside a housing. Wind turbines are often disliked by environmentalists because they kill birds and bats and often generate noise for the residents living nearby
  • Presently Fluid Dynamics Expert, John Dabiri, is very much on the quest of improving designs of wind turbines. Spotting behaviours that may throw light on energy-related practices in biological system and trying to implement that in real-life situations is part of that quest and Mr.Dabiri is jubilant that he is learning lessons from a school of fish! Water-energy, and wind energy are both studied.
  • GE, the US industrial group, is promoting and showing confidence in offshore wind technology by buying ScanWind, which makes direct-drive turbine components. This move will help in generating thousands of new jobs in the field of designing and manufacturing turbines. This move will affirm the confidence of investors in the fledgling offshore wind industry, which has been weighed down by concerns about costs and reliability. GE is moving ahead with establishing turbine manufacturing facilities to serve the European markets at first. They have to make up their mind about the size of the investment and location
  • The Metropolis Magazine has been holding Next Generation Design Competition since 2003. They want to provide a platform for young designers to promote the spirit of activism, social involvement, and entrepreneurship. They offer prize money of $ 10,000. But the real attraction is the publicity given to the projects of winners and runners-up. This recognition helps abstract ideas take concrete forms. For 2009, the theme for the Next Generation Design Competition was: How do we fix our energy addiction? They offered some guidelines, "Think about how we live and work, what we use, how we get where we need to go, hidden costs to our pocket books and the environment, across the whole design spectrum. Focus on one area that needs fixing—products, interiors, buildings and landscape, communication systems, or anything else you can imagine—and develop your idea fully. And above all, think of our energy addiction as a design problem at all scales."
  • sector. Wind turbines generate clean and green power for us but they have certain precondition. One of it is the power unit has to be set up in strong wind area. But Green Energy Technologies has developed a brand new wind power generator known as the WindCube. It is smaller compared to the normal wind generator. WindCube is specially designed to set up on the roof of a building in urban and rural areas. WindCube carries a 22 x 22 x 12 feet framework and its single unit can produce a maximum of 60kW of power

HowStuffWorks "10 Incredible Wind Power Facts" - 0 views

  • 8: One Megawatt of Wind Energy = 2,600 Fewer Tons of Carbon Dioxide So, with all the noise about clean energy, what kind of improvement are we really talking about with wind? Consider that every year 1MW of wind energy can offset approximately 2,600 tons of carbon dioxide (CO2) [source: NREL], and the interest comes into focus. The simple math is less fossil fuel consumption equals less CO2. And measuring carbon reduction has become a key benchmark for monitoring the progress of alternative energy adoption.

Wind Power - 0 views

  • We have been harnessing the wind's energy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent - a wind turbine - can use the wind's energy to generate electricity.
  • Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor.
  • A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.

  • Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant. Several electricity providers today use wind plants to supply power to their customers.

  • The wind turns the blades, which spin a shaft connected to the generator and produces electricity. Turbine blades are designed in such a way that wind causes them to rotate, which rotates the shaft at low speed, with a gear at the end that itself is connected to small gear on high speed shaft that runs through alternator housing.
  • he generator produces electricity using the same principle as a generator of your car (depending on the turbine). Magnetic Rotor inside the generator on high speed shaft spins inside loops of copper wire that are wound around an iron core. The rotor creates “electromagnetic induction” as it spins around the inside of the core through the coils, which generates electrical power. The current is regulated and transmission network (or home network system connection), after some changes, so it can use in our homes or sent to a battery bank for storage.
  •  
    Most wind turbines turn in the moving air like blades of propeller aircraft and supply power to an electric generator that produces electricity. Wind turbines, rather than working as a fan in your house that uses electricity to generate wind, use wind power to generate electricity. - See more at: http://www.conserve-energy-future.com/Wind_Into_Energy.php#sthash.MFQJ5BOI.dpuf

How much CO2 does solar energy produce? | Ecooutfitters.net - 0 views

  • Let’s not hide the fact that manufacturing solar panels requires resources, fossil fuels that release CO2 emissions and add to our carbon footprint. However, it’s been shown in numerous studies that solar panel production releases nowhere near as much CO2 and other greenhouse gases as electric generated from coal, oil, natural gas, etc. (And you still need to produce the equipment to generate electricity from those sources as well.)
