Wind Energy

Wind Energy is energy contained in the force of the winds blowing across the earth’s surface. When harnessed, wind energy can be converted into mechanical energy for performing work such as pumping water, grinding grain, and milling lumber.   By connecting a spinning rotor to an electric generator, modern wind turbines convert wind energy, which turns the rotor, into electrical energy.
Wind is a clean and renewable source of energy.   Modern wind turbines have been installed in over 26 countries by the year 2007, including such as Germany, Denmark, India, China, and the United States.   This was to supplement to a more traditional sources of electric power, such as burning coal.   Design improvements such as more efficient rotor blades combined with an increase in the numbers of wind turbines installed, helped increase the world’s wind energy generating capacity by nearly 150 percent since 1990.
A wind turbine is a device that converts kinetic energy from the wind into mechanical energy.   A wind turbine gathers energy from the wind through the rotation of its blades.   This is mechanically generated energy from the movement that is then turned into electrical energy.   The amount of energy that they produce can vary with the size of the blades.
Without the wind, the turbine cannot produce energy.   Wind turbines usually stand very high off the ground because the wind speeds are generally higher, and much less turbulent.   Without the proper height they could miss the winds altogether.   Areas that are flat and clear with windy climates are the best areas for a wind turbine.   They can be put in groups called farms, to generate large amounts of energy.   Residential wind turbines are used for homes or other small buildings, although they do not provide a continual energy source.   Wind speeds need to rise above 7 to 10 miles per hour in order for the turbine to operate.   Most wind farms are found along the coast and open fields and gaps in the mountains, these areas have...
