How Do Wind Turbines Work? Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like
Wind design classes, as defined by the International Electrotechnical Commission (IEC), range from Class 1 (high wind) to Class 4 (very low wind). Many of the earliest wind projects in the United States
Modern commercial wind turbines produce electricity by using rotational energy to drive an electrical generator. They are made up of one or more blades attached to a rotor and an
The rotational energy produced by the shaft spins copper coils within a magnet housed in the generator. This magnet excites the electrons in the wire, producing electricity.
Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator,
Wind power or wind energy is a form of renewable energy that harnesses the power of the wind to generate electricity. It involves using wind turbines to convert the turning motion of
Customers can purchase renewable energy through unbundled renewable energy certificates (RECs), community choice aggregations (CCAs), and power purchase agreements (PPAs).
These large turbines can generate anywhere from 4.8 to 9.5 megawatts of power. Once the electricity is generated, it can be used, connected to the electrical grid, or stored for future use.
