Wind Show
Wind energy The kinetic energy generated by air flow. A form of transformation of solar energy. As the solar radiation caused by uneven parts of the Earth's surface heat, causing the pressure distribution in the atmosphere is not balanced, under the action of the horizontal pressure gradient, the air movement in the horizontal direction to form the wind. The total reserves of wind energy resources are very large, and the energy developed in the year is about 5.3 x 10 ^ 13 kWh. Wind energy is renewable clean energy, large reserves, widely distributed, but its energy density is low (only 1/800 of water), and unstable. Under certain technical conditions, wind energy can be exploited as an important energy source. Wind energy utilization is a comprehensive engineering technology, through the wind turbine wind kinetic energy into mechanical energy, electricity and heat and so on.
