2 days ago· In contrast, renewable energy sources accounted for nearly 20 percent of global energy consumption at the beginning of the 21st century, largely from traditional uses of biomass such as wood for heating and cooking
Wind turbines use the energy of the wind to spin an electric generator, which produces electricity. Wind turbines are commonly located on hilltops or near the ocean. In some countries, wind turbines have also been built in the ocean, either floating on the surface or using giant pylons extending to the sea floor.
Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling. Wind turbines may also reduce electricity generation from fossil
In modern wind turbines, wind rotates the rotor blades, which convert kinetic energy into rotational energy. This rotational energy is transferred by a shaft which to the generator, thereby producing electrical energy. Wind power has grown rapidly since 2000, driven by R&D, supportive policies and falling costs.
