MassCEC - About Wind Energy

Wind turbines harness wind energy to produce electricity that can be used to power homes and businesses across the Commonwealth. Wind power systems range from small turbines that power a single home or business to large, multi-turbine wind farms that feed into the grid and generate enough electricity to power thousands of Massachusetts homes. A typical wind turbine consists of a tower, a rectangular box-like nacelle at the top of the tower which houses the generator, and a rotor, which consists of the turbine’s hub and blades. Turbines generally require tall towers to access the higher wind speeds aloft and to avoid ground-level obstructions to wind flow, such as buildings or trees, which lower wind speeds. A turbine’s total height is commonly referred to as the blade tip height, which is the distance from the base of the tower to the tip of the blade at its highest point. Wind projects can provide long-term benefits for building and facility owners and project developers in the form of price stability, savings on future energy costs and income generated by selling excess electricity.
