WHAT IS WIND ENERGYWind power is useful in many forms of energy, as

in using wind mills for mechanical power, wind pumps for pumping water or drainage, sails to propel ships, wind turbines to make electricity.

Wind Power are sometime split into two types, offshore and land based operations.

 Wind energy is produced for power needs that comes from wind farms, great big windmill type and other place contraptions produce electricity because as the wind blows it turns the blades on a shaft, which powers a generator and more.

RENEWABLE WIND ENERGYNow days the windmill’s equivalent are a

turbine, that can use wind energy to generate electricity.

Wind energy is renewable because the earth's natural winds. Wind power does not have anything to be produced. It is the same basic concept as hydroelectric power.

SO WIND ENERGY IS RENEWABLE

ADVANTAGES OF WIND ENERGY Renewable cheap actually free.Although wind turbines can be very tall each

takes up only a small plot of land. Doesn’t pollute areas.

no fossil fuels are burnt to generate electricity from wind energy.

DISADVANTAGES OF WIND ENERGYLarge area required.

Wind turbines generally produce allot less electricity than the average fossil fuelled power station. Wind turbine construction can be very expensive and costly to surrounding wildlife during the build process.Kills animal.

How Wind Turbines WorkWind is a form of solar energy. Winds are

caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.

THIS IS HOW A WIND TURBINE LOOKS LIKE

HOW DOES WIND ENERGY PRODUCE ELECTRICITYWell a good way to think about this is that

wind turbines work exactly the opposite way to a fan.

Instead of using a fan to make electricity turbines use natural wind to make electricity.

And also you would be using electricity to start a fan to make the turbines move.

All turbines produce electricity consist of rotor blades which moves in a horizontal way around
