The following are the average wind speeds:Most tiny wind turbines require a minimum of 8 kph (2 m/s) to begin whirling.The normal cut-in speed for a small turbine when it first starts generating electricity is 12.6 kph (3.5 m/s).The greatest generation power is generated at a speed of 3654 kph (1015 m/s).The turbine is halted or braked at a maximum speed of 90 kph (25 m/s) (cut-out speed).
Good places for wind turbines are where the annual average wind speed is at least 9 miles per hour (mph)—or 4.0 meters per second (m/s)—for small wind turbines and 13 mph (5.8 m/s) for utility-scal.
High wind speeds yield more energy because wind power is proportional to the cube of wind speed. 4 Average annual wind speeds of 6.5m/s or greater at the height of 80m are generally considered comm.

6 FAQs about [How strong the wind is needed for wind power generation]
How much power does a wind turbine have?
Wind turbines have a power rating usually ranging from 250 watts (enough to charge a battery) to 10 kilowatts (enough to power a house) to six megawatts (enough to power more than 1600 houses). Just as the wind constantly changes, wind turbines are built to operate within a wide range of wind. Read more from the Sci NC team.
How fast should a wind turbine be?
Wind speeds in classes three (6.7 – 7.4 meters per second (m/s)) and above are typically needed to economically generate power. Ideally, a wind turbine should be matched to the speed and frequency of the resource to maximize power production.
What is the energy ratio of a wind turbine?
vironmental conditions. Considering that energy is the product of its time-rate, that is, the power with the elapsed time, this energy ratio is equal the ratio of average power P to the nominal power of the system P . For a single wind turbine this nominal power i
How many kilowatthours do wind turbines generate a year?
Total annual U.S. electricity generation from wind energy increased from about 6 billion kilowatthours (kWh) in 2000 to about 434 billion kWh in 2022. In 2022, wind turbines were the source of about 10.3% of total U.S. utility-scale electricity generation.
How much energy does a 1.5 kW wind turbine produce?
A 1.5-kW wind turbine will meet the needs of a home requiring 300 kWh per month in a location with a 14 MPH (6.26 meters per second) annual average wind speed. The manufacturer, dealer, or installer can provide you with the expected annual energy output of the turbine as a function of annual average wind speed.
What size wind turbine do I Need?
The size of the wind turbine you need depends on your application. Small turbines range in size from 20 Watts to 100 kilowatts (kW). The smaller or "micro" (20- to 500-Watt) turbines are used in applications such as charging batteries for recreational vehicles and sailboats. One- to 10-kW turbines can be used in applications such as pumping water.
