Larger rotor diameters allow wind turbines to sweep more area, capture more wind, and produce more electricity. A turbine with longer blades will be able to capture more of the available wind than shorter blades—even in areas with relatively less wind.
Can I buy a wind turbine?
One can consider purchasing a small wind turbine if the proposed site has wind speeds of at least 10 mph or 4.4 m/s (meters per second), and the average electricity bill is over a $150 per month. It is important to make any energy conservation and efficiency changes at the site before looking into a small wind turbine.
