THE HISTORY OF USING WIND ENERGY LOUIS PART

Slide 4

THE EARLIEST USE OF WIND ENERGY The history of using wind energy can trace bake to B.C. China is the earliest user of wind energy. We use wind energy in transportation and agriculture. Egypt also is the early user of the wind energy.

The usage of wind energy

Slide 14

Global wind power installations increased by 41,236 in 2011, bringing total installed capacity up to 238,351 MW, a 20.6% increase on the 197,637 MW installed at the end of 2010. For the last two years more than half of all new wind power was added outside of the traditional markets of Europe and North America, mainly driven by the continuing boom in China which accounted for nearly half of all of the installations at 18,000 MW. China now has 62,733 MW of wind power installed. As of 2011, 83 countries around the world are using wind power on a commercial basis.

Slide 17

How the wind turbine works

Slide 18

Wind is caused by differences in pressure. A wind turbine is a device that converts kinetic energy from the wind into electricity for distribution. There are three kinds of wind turbine: VAWT, Savonius, HAWT towered A wind turbine can be divided into three components: The rotor component The generator component The structural support component

Slide 22

The shortage of wind energy

Slide 23

Wind energy is the most clean energy source. With the technology and facility of wind energy becoming more and more progressive, it can largely decrease the prime cost of developing energy. Also, wind energy is the renewable energy, so harnessing wind energy can protect the landmark and ecological environment.
