In order to increase public awareness of renewable energy sources, the Biosphere has acquired two wind turbines. Wind turbines, or aerogenerators, convert the wind’s kinetic energy into electricity. Nonpolluting, wind energy is infinitely sustainable. Two different types of wind turbines were set up on the highest platform of the building, inside the geodesic structure, the Biosphere’s two wind turbines are each of a different type.



The first one, a domestic type with three blades, has a horizontal axis and an average power output of 1.8 kilowatts (kW), based on an annual average wind speed of 20 km/hour. It produces approximately 4800 kWh (kilowatt-hours) per year, or 13 kWh per day.This energy production represents approximately one-quarter of the electricity consumption, including heat, for three to five people living in a single-family house. The second, a commercial-type turbine, has a vertical axis and has an output of 5 kW. This five-metre-diameter vertical-axis wind turbine is noiseless and is safer for birds.
