When dealing with wind energy, we are concerned with surface winds. 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. The kinetic energy of a moving body is proportional to its mass or weight. The kinetic energy in the wind thus depends on the density of the air, i. In other words, the “heavier” the air, the more energy is received by the turbine. The rotor area determines how much energy a wind turbine is able to harvest from the wind. To be considered a good location for wind energy, an area needs to have average annual wind speeds of at least 12 miles per hour.

Modern wind turbines are designed to work for some , hours of operation throughout their design lifetime of 20 years. 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. 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.

Suitable areas for wind farms are often near the coast, where land is expensive. Some people feel that covering the landscape with these towers is unsightly. Can kill birds – migrating flocks tend to like strong winds. However, this is rare, and we tend not to build wind farms on migratory routes anyway. Can affect television reception if you live nearby. Can be noisy. Wind generators have a reputation for making a constant, low, “swooshing” noise day and night, which can drive you nuts.

Wind is free, wind farms need no fuel. Produces no waste or greenhouse gases. The land beneath can usually still be used for farming. Wind farms can be tourist attractions. A good method of supplying energy to remote areas. Wind speeds rise and fall gradually and the system operator has time to move other plants on and off line as needed. A MW wind plant requires about 2 MW of conventional capacity to compensate for changes in wind. Wind turbines operate when the wind is blowing, which tends to be louder than turbine noise.

A modern operating wind farm at a distance of to 1, feet is no noisier than a kitchen refrigerator or a moderately quiet room. Normally, it should not be a problem in the U. Power quality problems caused by wind farms are the exact mirror-image of connecting a large electricity user, e.

Flicker may occur if a wind turbine is connected to a weak grid. Flicker can be reduced with proper turbine design. The materials used to make such machines are non-metallic composites, plastic, wood. Small turbines are too small to create electromagnetic interference EMI by “chopping up” a signal. Large wind turbines can interfere with radio or TV signals if a turbine is in the “line of sight” between a receiver and the signal source. Alleviate the problem by: improving the receiver’s antenna installing relays to transmit the signal around the wind farm.

Upon having the first impression of a Wind turbine, people want to know exactly how such a device helps create electricity.

Explain how the rotatory motion of the turbine helps it to create electricity with the help of free Wind turbine PPT theme. As the blades move in a circular motion, a generator from within gets charged and electricity is generated through a process known as electromagnetic induction.

Wind Energy. Alex, Isabel, Jack, Kameron. When wind blows onto the blades, they spin in circles creating energy to power homes and other sources. Wind turbines are placed in open lands, ideally by water where more wind is generated.
