Wind Power

Wind power is a renewable source of energy that can be harnessed through wind turbines to generate electricity. Large wind farms consist of hundreds of turbines connected to transmission networks, while small, onshore wind farms provide power to isolated locations. Wind power produces no greenhouse gas emissions and has relatively minor environmental effects compared to other energy sources. Denmark generates over a quarter of its electricity from wind, and wind energy production globally was over 2.5% of total electricity usage in 2010. While wind power output varies over short time scales, techniques such as energy storage and grid interconnections can mitigate intermittency issues.

Wind power:-

Wind power is the conversion of wind energy into a useful form of energy, such as using wind
turbines to make electrical power, windmills for mechanical power, wind pumps for water
pumping or drainage, or sails to propel ships.
Large wind farms consist of hundreds of individual wind turbines which are connected to the electric
power transmission network. Offshore wind is steadier and stronger than on land, and offshore farms
have less visual impact, but construction and maintenance costs are considerably higher. Small
onshore wind farms provide electricity to isolated locations. Utility companies increasingly buy surplus
electricity produced by small domestic wind turbines.
[1]

Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces
no greenhouse gas emissions during operation and uses little land.
[2]
The effects on the
environment are generally less problematic than those from other power sources. As of 2011,
Denmark is generating more than a quarter of its electricity from wind and 83 countries around the
world are using wind power on a commercial basis.
[3]
In 2010 wind energy production was over 2.5%
of total worldwide electricity usage, and growing rapidly at more than 25% per annum. The monetary
cost per unit of energy produced is similar to the cost for new coal and natural gas installations.
[4]

Wind power is very consistent from year to year but has significant variation over shorter time scales.
The intermittency of wind seldom creates problems when used to supply up to 20% of total electricity
demand,
[5]
but as the proportion increases, a need to upgrade the grid, and a lowered ability to
supplant conventional production can occur.
[6]
Power management techniques such as having excess
capacity storage, geographically distributed turbines, dispatchable backing sources, storage such
as pumped-storage hydroelectricity, exporting and importing power to neighboring areas or reducing
demand when wind production is low, can greatly mitigate these problems.
[7]
In addition, weather
forecasting permits the electricity network to be readied for the predictable variations in production that
occur.

USES:-
1. Wind turns the turbine blades
2. Spinning the shaft.
3. Generate Electricity
4. An inverter converts electricity from DC to AC
5. Electricity is connected directly to main power or connected to a batter bank.
