Wind Turbines are used to power electric generators and allows wind to be used as an alternative fuel. Wind Power is used to power homes, businesses, schools, etc.
The simplest possible wind turbine consists of 3 crucial parts: rotor blades, shaft, and the generator. Among three designs for floating giant wind turbines in the deep ocean, MIT research is focusing on the tension leg platform (center), a system that oil companies use for deep-water rigs.

Basing their work on decades of wind energy research and experience, Sandia engineers are creating several concept designs, running those designs through modern modeling software and narrowing those design options down to a single, most-workable design for a VAWT turbine-blade. Results aren’t in, but the early favorite for further testing is the Darrieus design. (Illustration by Josh Paquette and Matt Barone). Wind Turbines are going to be put in the oceans where winds are stronger.
Wind is the fastest growing energy source in the world. The average annual growth rate is 28% compared to 3% for fossil fuels. The major reasons for this growth is climate change and energy security. Wind energy is still a little of the total energy worldwide. Increasing wind power will require significant political support.
Friendly to the environment Fossil fuels are not needed to generate wind energy Wind turbines doesn’t take up a lot of space Renewable Widely distributed Doesn’t release toxic gases
Has an unreliable factor Produces less electricity than an average fossil fuel station Construction is costly Cannot only rely on wind energy
Wind power is currently the fastest- growing source of electricity production A single wind turbine can power 500 homes More than 1/3 of all new generating capacity installed in America since 2007 is wind power US wind power produces as much electricity as nearly 10 nuclear power plants The on-shore wind in America is enough to power the country 10 times over. Modern wind turbines produce 15 times more electricity Wind Power uses virtually no water and by 2030, wind power will save about 30 trillion bottles of water
Example 1: China produces the largest amount of wind energy Example 2: Wind power produces as much as 45% of the electricity in Spain Example 3: China used wind for pumping water several millennium ago.
Wind Turbines harm small birds The primary impact of wind power is visual, wind turbines are usually in prominent locations because they must be exposed to wind From about 100 feet the noises made by wind turbines can be compared to the sound of a refrigerator
Wind Energy is effective because: › It is a source of clean renewable energy › Will reduce carbon emissions and coal consumption › Provides economic benefits › Widely Available › It is a form of solar energy › Most cost effective › Relatively quiet
Wind energy is more efficient than fossil fuels. Example 1: wind energy provides Great Britain with 14 TWH (Terra-Watt hours) of electricity and fossil fuels provide it with 372 TWH but it can lose 54% of its energy. Example 2: Wind power’s capacity, factor is 30% on shore and 40% off shore and fossil fuels are nearly always below this amount.
Wind energy is globally used and is the world’s fastest growing technology. In the US wind power is about 1% of the energy. Wind power provides electricity without polluting the air. They are places at cities with strong winds. It does not generate enough electricity to accommodate all of our needs. However, it is most commonly used in the US, India, Germany, France, Spain, UK, China, Denmark, Italy, and Portugal.
The US Department of energy exploring to create alternative uses for wind power such as combining wind with hydropower to use in electrical power grid networks. Lawrence Livermore National Laboratory is trying to forecast wind energy at any given time
