  • How do turbines operate?

Wind 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.

The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

So how do wind turbines make electricity? Simply stated, 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 connects to a generator and makes electricity. Take a look inside a wind turbine to see the various parts. View the wind turbine animation to see how a wind turbine works.

This aerial view of a wind power plant shows how a group of wind turbines can make electricity for the utility grid. The electricity is sent through transmission and distribution lines to homes, businesses, schools, and so on.


  • Who manufactures turbines?

LM Glasfiber is the worlds leading supplier of blades for wind turbines, and the only supplier that operates on a global basis. We have achieved this strong position in a business distinctive for international growth via a consistent focus on research, product development, quality and excellent customer service.

  • Which are the country front runners for wind energy?

Netherlands are the leading front runners for wind energy.

  • Finally, where's the catch?

There are many dis-advantages for this such as the noise, it ruining the view and even killing birds. The main one has to be the change of environment that will damage many habitats.
