Wind in action: When wind strikes an object, it exerts a force in an attempt to move it out of the way. Wind Today!!! It can generate to kilowatts of power- a nearly tenfold increase in efficiency. C, powered by wind. Wind turbines convert the kinetic energy in the wind into mechanical power.
This download powerpoint presentation wind energy free power can be used for specific tasks such as grinding grain or pumping water or a generator can convert this mechanical power into electricity.
A wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which The energy in the wind download powerpoint presentation wind energy free two or three connects to a generator and makes electricity.
The rotor is connected to the main download powerpoint presentation wind energy free, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy.
At feet 30 meters or more above ground, they can take advantage of faster and less turbulent wind. A Wind Turbine 5. Specific components Description Wind turbine 2. Is the rotor. The rotor provides the blades to rotate. This is brake. Then it will brake and stop the wind turbine. The small cog wheel rotates faster than the big cog wheel.
This is the generator. Is the tower. The entrance is placed in the bottom of the tower 7. How the does a wind turbine works? Wind turbines operate on a simple principle: The energy in the wind turns the propeller-like blades around a rotor. The pitch of the blades makes optimum use of the wind direction. The rotor is connected to the main drive shaft, which spins a generator to create electricity.
At 30 metres or more above ground, they can take advantage of faster and less turbulent wind. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid for more widespread electricity distribution. Download powerpoint presentation wind energy free and Disadvantages??? Advantages: No pollution. Disadvantages: Depending on how energetic a wind site is, the wind farm may or may not be cost competitive.
Wind energy cannot be stored unless batteries are used Good wind sites are often located in remote locations Wind resource development may compete with other uses for the land and those alternative uses may be more highly valued than electricity generation.
