what is the average wind speed needed for a turbine?
150109
In general, wind speeds are as follows: 8 kph (2 m/s) minimum is required to start rotating most small wind turbines. 12.6 kph (3.5 m/s) is the typical cut-in speed, when a small turbine starts generating power. 36–54 kph (10–15 m/s) produces maximum generation power.

The World's Biggest Wind Turbine Starts Generating Enough Electricity To Power 30,000 Homes. The most powerful offshore wind turbine ever made, the Haliade-X 12 MW, is currently generating energy off the coast of the Netherlands, and sending power to Eneco, the Dutch utility.

Wind turbines manufactured today have power ratings ranging from 250 watts to 7 MW. An onshore wind turbine with a capacity of 2.5–3 MW can produce more than 6 million kWh in a year – enough to supply 1,500 average EU households with electricity.

['There must be no other wind turbine or air source heat pump on the property.', "The bottom of the turbine's blades must be at least 5m from the ground.", 'The turbine site must not be in a Conservation Area, World Heritage site, or in the grounds of a listed building.']

Wind turbines need to be positioned so that the distances between them are between 3-10 rotor diameters (about 180-600 metres for a wind farm using 60m diameter, 1.3MW wind turbines) depending on the individual circumstances of the site.

The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. Wind turbines manufactured today have power ratings ranging from 250 watts to 7 MW.

The instruments used to measure wind are known as anemometers and can record wind speed, direction and the strength of gusts. The normal unit of wind speed is the knot (nautical mile per hour = 0.51 m sec-1 = 1.15 mph).

average wind speed = 10 m/s (20 mph) Power = 0.0006 x 0.42 x 1000 = 250 Watts per square meter. Electricity generated is then . 25 KWH per sq.

As of 2020 the Republic of Ireland has 3700 megawatt (5,030 MW all-island) of installed wind power nameplate capacity. In 2015 wind turbines generated 23% of Ireland's average electricity demand, one of the highest wind power penetration in the world.

Larger blades allow the turbine to capture more of the kinetic energy of the wind by moving more air through the rotors. However, larger blades require more space and higher wind speeds to operate. As a general rule, turbines are spaced out at four times the rotor diameter.

In the case of wind speed, vector-averaged speeds will never be larger than the scalar-averaged values and will generally be lower. Larger differences will occur with greater wind direction variance, which typically occurs at lower wind speeds (below about 2 meters per second).

Sizing Small Wind Turbines Small wind turbines used in residential applications typically range in size from 400 watts to 20 kilowatts, depending on the amount of electricity you want to generate. A typical home uses approximately 10,932 kilowatt-hours of electricity per year (about 911 kilowatt-hours per month).

5m x 14L/s x 9.81 x 0.75 = 515 watts of power. A 500W Hydro turbine may not sound very big, but it runs 24 hours per day, 365 days per year. It will produce around 4,000kWh per year and a reasonably energy efficient house will use about 5,000kWh per year.

The first electricity-generating wind turbine was invented in 1888 in Cleveland, Ohio by Charles F. Brush. The turbine's diameter was 17 meters (50 feet), it had 144 rotor blades made of cedar wood, and it generated about 12 kilowatts (kW) of power.

The wind speed required for erosion depends on the size, weight and wetness of the soil particles. Movement of small, disturbed particles begins with light gusts of wind, however wind speeds of 20 to 30 kilometres per hour are required for significant erosion to occur.

The capacity factor is the average power generated, divided by the rated peak power. Let's take a five-megawatt wind turbine. If it produces power at an average of two megawatts, then its capacity factor is 40% (2÷5 = 0.40, i.e. 40%).

Hydropower plants use flowing water to spin a turbine connected to a generator. Wind energy was the source of about 7% of total U.S. electricity generation and about 42% of electricity generation from renewable energy in 2019. Wind turbines convert wind energy into electricity.
