Wind turbines can turn the power of wind into the electricity we all use to power our homes and businesses. They can be stand-alone, supplying one or a very small number of homes or businesses, or they can be clustered to form part of a wind farm. Each of turbine consists of a set of blades, a box beside them called a nacelle and a shaft.
A grid-connected system allows you to power your home or small business with renewable energy during those periods (daily as well as seasonally) when the sun is shining, the water is running, or the wind is blowing. Any
