Wind Power

Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines.

Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator.

Wind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity to rural residences or grid-isolated locations.

Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and greenhouse gas emissions if used to replace fossil-fuel-derived electricity.

As a general rule, wind generators are practical where the average wind speed is 10 mph (16 km/h or 4.5 m/s) or greater. Usually sites are pre-selected on basis of a wind atlas, and validated with wind measurements. Meteorology plays an important part in determining possible locations for wind parks but meteorological wind data alone is usually not sufficient for accurate sitting of a large wind power project.

 

 

THE WIND CAN PROVIDE FOUR TIMES MORE ENERGY THAN WE NEED

 

 

Best and Biggest

 

 

The largest wind farm so far has been constructed in Portugal and comprises 120 wind turbines and 5 substations, the value of investment being 400 million euro.

 

World’s largest offshore wind farm is situated in Denmark. Horns Rev 2 Wind Farm developed by state’s company Dong Energy amounts 3.5 billion DKK (694 million USD) and has installed capacity of 209 MW.

 

With its capacity of 156 MW, AES Geo Energy’s “Sveti Nikola” Wind Farm is the largest in Bulgaria so far. The investment comes to 270 million euro.
