A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind turbine generator (WTG), wind power unit (WPU), wind energy converter (WEC), or aerogenerator.
for complete reference, here is book that explain to us about wind turbine component and operation

Among the various renewable energy source wind energy is one among the fastest growing resources. It's the clean resource for producing electricity.
Missouri Wind and Solar have Falcon Mach 4 blades. 80.5 inch diameter aluminum blades that are advertised as bring "Precision Balanced". I bought a set that vibrated like crazy and upon inspection I found them out of balance more that 3.5 oz. How are they balanced if there are no weights added on or any material removed to the blades? Has anybody else had balance problems with Falcon Mach 4 blades?
