Wind Power

Types of Wind Turbines

• A rotor that consists of 2 or 3 blades attached to a hub.

• A generator that produces electricity in the form of alternating current.

• Control and Protection system that optimizes performance and keeps the machinery operating with safe limits.

• The tower that raises the rotor off the ground.

Four Main Components Of Wind Turbines

Parts To a Wind Turbine

• Long tall towers with propellers on the top about 40 to 80 meters up in the air.

• The propellers spin around from the wind. Which turns a turbine, which creates electricity that can power many homes.

• The propellers on top are usually the same size or half the size of the height of the tower.

How is Power Produced?

• Free and efficient.• Does not release any harmful pollutants or gases.• One of the cheapest forms of energy available today.• Wind is a never ending resource.Pros• Can get damaged or completely destroyed when hit by a

heavy storm.• On an average make a sound of about 50-60 decibel.• Production of electricity would not always remain

consistent.• rotating blades of the turbines have proved fatal for bird.Cons

Pros and Cons

Size of Wind Turbines

• A typical turbine with a 600 kW electrical generator will typically have a rotor diameter of some 44 meters (144 ft.).

• Wind power is the fastest growing form of alternative energy.

• 40% of all generation capacity added to the electric grid came from wind energy.

• Electric utilities are adding Wind to their establishments more and more everyday.

Facts

• Wind farms, while very expensive to set up originally benefit in the end, making up for the money spent on them originally.

• In 2005, wind accounted for 1% of the total electricity production in the world. The United States was third in utilization of wind energy, with Germany being the leading producer. According to the Department of Energy, offshore wind farms could provide enough energy to power the entire nation. Clearly what we see here is that we have barely touched the amazing capabilities of wind power, and we can expect to see wind power become a massive source of renewable energy in the U.S., and around the globe
