What are the environmental benefits of using wind power?
Wind is a clean fuel and offsets pollution from other sources, such as electric power generated by your utility company. A typical 10 killowatt (kW) wind turbine will offset approximately 1.2 tons of air pollutants, and 250 tons of greenhouses gases over its operating period. Can I sell excess energy back to the utility company? If your system is connected to a utility grid (grid-tied system), and produces more energy than your home uses, utility companies buy back the excess power. This buy back is called Net Metering or a Feed-In-Tariff. During times of excess energy, the inverter converts electricity to the utility’s standards, allowing the company to purchase the energy as it flows backward through your meter. Currently, 39 states allow connection of PV to the grid, and 36 states require net metering for utility companies. Ask your utility company about local policy. A customer may use power from the utility during the night or on a cloudy day. At the end of the month or year, the
