4. Introduction All renewable energy (except tidal and geothermal power), ultimately comes from the sun. The earth receives 1.74 x 10 17 watts of power (per hour) from the sun. About one or 2 percent of this energy is converted to wind energy (which is about 50-100 times more than the energy converted to biomass by all plants on earth.

5. A wind turbine obtains its power input by converting the force of the wind into a torque (turning force) acting on the rotor blades. The amount of energy which the wind transfers to the rotor depends on the density of the air, the rotor area, and the wind speed. A typical 600 kW wind turbine has a rotor diameter of 43-44 meters, i.e. a rotor area of some 1,500 square meters. The rotor area determines how much energy a wind turbine is able to harvest from the wind .

8. A Windmill captures wind energy and then uses a generator to convert it to electrical energy. The design of a windmill is an integral part of how efficient it will be. When designing a windmill, one must decide on the size of the turbine, and the size of the generator. Working principal and design criteria

9. A windmill built so that it too severely interrupts the airflow through its cross section will reduce the effective wind velocity at its location and divert much of the airflow around itself. Modern Windmills can attain an efficiency of about 60 % of the theoretical maximum. Most common design is the three-bladed turbine. The most important reason is the stability of the turbine. A rotor with an odd number of rotor blades (and at least three blades) can be considered to be similar to a disc when calculating the dynamic properties of the machine.

10. A rotor with an even number of blades will give stability problems for a machine with a stiff structure. The reason is that at the very moment when the uppermost blade bends backwards, because it gets the maximum power from the wind, the lowermost blade passes into the wind shade in front of the tower. 3-BLADE 2-BLADE 1-BLADE

11. Calculation of wind power  = Effect of air density, A = Effect of swept area, V = Effect of wind speed. R Swept Area: A = πR 2 - Area of the circle swept by the rotor (m 2 ). Power in the Wind = ½ρAV 3

12. Importance of wind speed No other factor is more important to the amount of power available in the wind than the speed of the wind. Power is a cubic function of wind speed V X V X V 20% increase in wind speed means 73% more power. Doubling wind speed means 8 times more power.

17. Produced electricity distribution

18. The wind blows day and night, which allows windmills to produce electricity throughout the day. (Faster during the day) Energy output from a wind turbine will vary as the wind varies, although the most rapid variations will to some extent be compensated for by the inertia of the wind turbine rotor. Wind energy is a domestic, renewable source of energy that generates no pollution and has little environmental impact . Advantages of Wind Power

19. Up to 95 percent of land used for wind farms can also be used for other profitable activities including ranching, farming and forestry. The decreasing cost of wind power and the growing interest in renewable energy sources should ensure that wind power will become a viable energy source in the United States and worldwide.

20. Wind Turbines and the Landscape - Large turbines don’t turn as fast  attract less attention - City dwellers “dwell” on the attention attracted by windmills Sound from Wind Turbines - Increasing tip speed  less sound - The closest neighbor is usually 300 m  experiences almost no noise Disadvantages

21. The only known site with bird collision problems is located in the Altamont Pass in California. Danish Ministry of the Environment study revealed that power lines are a much greater danger to birds than the wind turbines. Some birds even nest on cages on Wind Towers.
