Wind energy

Wind energy belongs to the set of renewable energy sources or also known as alternative energies. Wind power is the kind of renewable energy more widely at the international level by installed power (Mw) and energy generated (Gwh). Wind power comes from energy of the Sun (solar energy), are changes in pressure and temperature in the atmosphere that make putting air in movement, causing wind, which take advantage of wind turbines to produce electricity through the movement of their blades (kinetic energy). More than 15.000.000 million kW/h of electricity are generated annually around the world. Of this, near the 65% is produced by burning fossil fuels and the rest is obtained from other sources, including nuclear, hydropower, geothermal, biomass, solar and the wind. Only than the 0.3% of this energy is produced by converting the kinetic energy of the wind into electrical energy, however, the use of the wind for electricity production is has been spreading rapidly in recent years, due in large part to technological improvements, the maturation of the industry and a growing concern for the emissions associated with the burning of fossil fuels. There is still much room for growth, because only a small portion of the usable wind resource is being exploited. Through the regulations for the electrical industry, as well as incentives by Governments, play an important role in how quickly will adopt wind power. Effective policies will help to pave the way and ensure that wind power can compete with other energy sources in the electricity market.
