Wind energy | Open Energy Information
Instead of using electricity to make wind, like a fan, wind turbines use wind to and are typically used in remote, off-grid locations where a connection to the. There is unprecedented interest in renewable energy, as sources of sustainable energy, particularly solar and wind energy, which provide electricity with low. Wind energy (or wind power) describes the process by which wind is used to since the American Wind Energy Association began tracking the categories.
Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks such as grinding grain or pumping water or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.
HOW A WIND TURBINE WORKS
Wind Turbines Wind turbines, like aircraft propeller blades, turn in the moving air and power an electric generator that supplies an electric current. Simply stated, a wind turbine is the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity.
- Wind energy
The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Wind Turbine Types Modern wind turbines fall into two basic groups; the horizontal-axis variety, like the traditional farm windmills used for pumping water, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor.
Most large modern wind turbines are horizontal-axis turbines. Turbine Components blade or rotor, which converts the energy in the wind to rotational shaft energy; a drive train, usually including a gearbox and a generator; a tower that supports the rotor and drive train; and other equipment, including controls, electrical cables, ground support equipment, and interconnection equipment.

Wind Energy - Using the Power of Wind
Electricity from these turbines is fed into a utility grid and distributed to customers, just as with conventional power plants. See Wind Energy Photos page for wind farm photographs.
Wind Turbine Size and Power Ratings Wind turbines are available in a variety of sizes, and therefore power ratings. The largest machine has blades that span more than the length of a football field, stands 20 building stories high, and produces enough electricity to power 1, homes.
From the above brief explanation, it could be seen that wind energy is a secondary form of solar energy.
Sun heats up air that turns to wind producing motion and energy. Wind Energy is caused by the motion of the wind. This kind of energy is called Kinetic Energy. This energy can be harnessed to provide mechanical energy for driving mechanical systems and for providing electricity.
The amount of energy available from wind depends on the speed of wind.
The speed of wind, on the other hand, is determined by Air density, Air temperature, Air pressure, and Altitude. Temperature decreases with height, while pressure increases. Wind effects are more pronounced at high altitudes. The wind speed is lower with higher density. Uses of Wind Energy?
Wind Energy - Using the Power of Wind
Wind Energy provides a suitable energy alternative to the traditional fossil fuel energy sources that are currently widely in use.
Previous and current applications of wind energy are: This is the current, most extensive use of wind energy.
Further discussions on wind turbines follow Wind Turbines Wind turbines transform energy from wind into electricity. Wind turbines perform optimally when placed at locations that are optimally windy and preferably at high altitudes. Power output vs wind speed graph as shown below.
Alliant Kids - Wind Energy
WEG layout is optimised and Micro-siting Map is prepared using software and then estimated is energy generation. Once the site, make and rating of WEG and the selling option are finalized, detailed survey and field study is conducted. Comprehensive layout design is prepared with optimization of generation along with detailed design for approach road and grid evacuation.
Detailed costing and financial analysis is carried out to establish overall viability. Not only quality of works needs to be checked, it is equally important to ensure close co-ordination and monitoring for timely commissioning. Energy generation with respect to wind resource, frequency and type of machine and system failures needs to be critically monitored and analyzed to optimize generation.
Income from WPP can be optimized only if break down and failure of WEG and evacuation system is avoided particularly during the limited high wind months. For the existing Wind Power projects also there is often need to ensure its performance improvement, which goes down with time.
