Wind Turbines- Not Only For Sight Seeing

            If you have ever taken a road trip you have most likely passed large wind generators that look like giant fans sitting atop hills. These generators are devices designed to convert the energy of wind into usable electricity. This happens when the energy of the wind (kinetic energy) is transferred into mechanical energy through turbine generators. The most top-notch generators have efficiencies of about 35% to 40%. The lowest speed that the generators have is called cutting speed. This speed is usually 4 to 5 m/s, this is due to the fact that there is not enough energy to overcome the total loss of the system. Higher cutting speeds of the generators are measured by the total capacity of the machine and how well it can withstand strong winds. Overall these machines are very useful and are a great way to produce electricity without polluting our environment.
