Wind power is the conversion of the energy in wind into a more useful form of energy. It is a renewable source of energy which helps to cut down on the pollution of earth’s air. Wind power capacity has expanded quickly in these years and wind energy production was about 4% of total worldwide electricity usage and growing fast. It is widely used in European countries, and more recently in the US and Asia.
Pie chart-------demonstrates the percentage of using WE in some countries such as A,C,G . It is clear that America and china occupy larger proportions than other countries.
Map-------It strikingly shows the usage of WE by shades of colors.
When people talk about WE, they usually think that WE could be translated into electricity. However, it also could be used to pump water. Therefore, I will first introduce the process of generating electricity to you then give simple demonstration of pumping water.
This is a cartoon of wind turbine. We can easily demonstrate the process.
1.Wind turns the turbine blades 2. Movement of blades spins the shaft which generates electricity 3. An inverter converts electricity from DA to AC 4.Alternate current moves towards storage space or main power line.
The easiest and commonly used wind electricity generation method is using wind turbines.
What’s more, the wind can play an important role for the water supply and irrigation of agriculture land. In fact, underground water can be pumped by wind energy pumping system. 1. 2. Movement of blades spins the shaft which turns mechanical water pump. Water is extruded from pump into pipe.

Besides these, recommend EWEA. It starts in 1982. Nowadays, it has over 600 members, which are active in over 50 countries, making EWEA the world’s largest and most powerful wind energy network.
The European wind power industry plays an important role in
