Wind Power Explained

Wind TurbinesWind energy came into being around 5,000 years ago with the Egyptians using wind energy to sail their boats from one shore to shore across the River Nile. Today, not only does the wind continue to power our sailing boats but it powers wind turbines that generate huge amounts of electricity.

Wind is created when sun’s energy when comes into contact with the earth’s surface. So, as long as the sun shines brightly, wind will remain a source of abundant energy. Today there is a growing awareness from politicians, industrialists and the public in the benefits that wind energy has to offer. Small wind turbines intended for domestic uses are likely to supply 2.5 to 6 kilowatts of electricity.

Although we are accustomed to seeing wind farms in the country, usually sited in higher open spaces, the urban skyline too is featuring specially designed taller wind turbines. These turbines are usually installed in places with no electricity grid or with no grid connections.

Wind turbines consist of a controller or special type of inverter to convert DC electricity into AC electricity at an acceptable quality standard. Grid connected systems require no battery storage facility as excess electricity is exported directly to the grid and sold to national or regional electricity suppliers

Wind turbines intended for domestic use produce 2.5 KW of electricity, equal to the amount of electricity required by an average household in a year. Such turbines will produce sufficient power to support the loads required to operate electrical apparatus such as freezer, fridge, vacuum cleaner, washing machine, computer, television, lights, along with enough remaining power to operate a water heater.

The cost of installing a wind turbine ranges from £2,500 to £5,000 pounds per KW of electricity.
