1. WIND POWER

2. INTRODUCTION I’m going to explain some things about wind power, like: The importance of this in Spain The most important characteristics And others… I’ve decided to treat this theme because, in my opinion wind power is a renewable energy that is starting to have importance in this country. In the future it will be more important than fossil fuels, because it has a lot of advantages respect fossil fuels.

3. WHAT IS WIND POWER? Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships.

4. RENEWABLE ENERGY -Wind power is a renewable energy Climate concerns and dwindling fossil fuel resources are driving an increasing demand for renewable energy solutions. Safe and Secure: Energy sources that are perpetual, or self-renewing, guarantee a secure supply, thus minimizing dependency on outside energy suppliers. At the same time, the use of renewable energy cuts emissions of carbon dioxide, thereby addressing environmental concerns.

5. ELECTRICITY GENERATION In a wind farm, individual turbines are interconnected with a medium voltage, power collection system and communications network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage electric power transmission system.

6. WIND POWER IN SPAIN Spain is the world's fourth biggest producer of wind power, after the United States, Germany and China Wind power is an important energy source in Spain because the Spanish government has introduced a green energy approach to guarantee an increase in the country’s wind generation capacity, with expectations to install a total of 20.1 GW of wind power by 2010. Increase in installed wind power capacity in recent years in Spain is shown in the Table below.

8. FURTHER INFORMATION Most of the energy stored in wind movements can be found at high altitudes where continuous wind speeds of over 160 km/h occur. Eventually, the wind energy is converted through friction into diffuse heat throughout the Earth's surface and the atmosphere.
