Wind Power Generation Equipment Production

Wind Power Generation Equipment Production

Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. Benefiting from technological innovation and policy support,the new installed capacity of global wind power is 93. [pdf]
