HISTORY:• Wind power is one of the oldest energy with thermal energy has been used to grind grain or sails to propel ships so they could move.• In Spain opened the first wind farm in 1984 in Garriguella (Gerona). This consisted of five wind turbines.• Later first commercialized in other countries and territories.
DEFINITION:• Wind energy is a renewable energy source that uses wind power to generate electricity. The primary means to obtain it are the turbines, "windmills“.
• FEATURES: using wind Wind energy is a type of clean, renewable energy power to generate electricity.• The amount of energy that can be produced depends on the size of the turbine. A greater length of the blades, more power is obtained and therefore more energy.• The wind turbines are in the wind farms.
TURBINE TYPES: Vertical axis wind turbine•The turbine blades are rotating in a plane parallel to the ground. Horizontal axis wind turbine: •Involves putting the power train in the top along the axis of rotation.
ADVANTAGES OF WIND ENERGY:• It is a type of renewable energy.• It is a clean energy because it produces no emissions or polluting waste.• It does not produce carbon dioxide (CO2), so it does not contribute to the greenhouse effect and climate change.• It can coexist with other land uses, such crops.• Create a large number of jobs in assembly plants and installation areas.• Installation and maintenance is fast
DISADVANTAGES OF WIND POWER:• It’s random, as it depends on the wind.• They can be a danger to flying animals.• Wind farms require large tracts of land.• Produce negative visual impacts on the landscape.• Generate strong acoustic impacts.• Your installation may be very excessive.
WIND ENERGY IN SPAIN: The wind broke the record and providing 64% of electricity inSpain in early 2013. Wind energy is the third largest source of electricity generation inSpain, behind the nuclear and coal. Spain is the fourth country in the worldfor installed wind power, after China, the U.S. and Germany. The largest wind farms are located inCastilla y León, Galicia, Andalusia,Canary Islands, Navarra and Aragon.
WIND ENERGY IN MURCIA:the region of Murcia.• Wind power occupies 3% of electricity in• The Murcia region increased 15.5 percent wind energyproduction in 2010.• Murcia is the second Spanish region with the highest growthin the wind power in the last two years, only behind Andalucía
