- Each turbine produces about 2,000,000 kilowatt hours (kwh) per year, enough energy to power as many as 500 typical homes at 12,000 kwh per year. How strong do the winds have to blow for the blades to rotate? Wind turbines start operating at wind speeds of around 8 mph and reach a maximum power output at around 33 mph. When there is not enough wind to turn the blades, or when there is too much wind the turbines shut down. How much do wind turbines cost? It costs over $2.5 million to set up a 1650 KW turbine. How many turbines are there in Minnesota?

Wind turbine generators: How do they work? The wind industry uses induction and permanent-magnet designs. There are many variations of these two, but in general terms, the induction generator must be spun at about 1,000 rpm or more to produce useful power. It produces current by first generating an electric field by passing alternating current (ac) through a coil.

Wind energy Wind power involves converting wind energy into electricity by using wind turbines. A wind turbine is composed of 3 propellers-like blades called a rotor. The rotor is attached to a tall tower. The tower looks like a very tall pole. On average wind towers are about 20m high.

How Do Wind Turbines Work? Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover.he terms  wind energy  or  wind power  describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.

- As a wind turbine will generally bring in a lease value of $5000 - $8000 per year to the owner of the land, and as that is higher than most crops will yield per acre per year, it's an excellent additional revenue stream, especially for the multi-revenue stream, small-business owners we call farmers.t is not the fault of the system, but average winds. Wind Turbines are rated at between 25 and 28 MPH winds. If the wind goes over 31 MPH, most systems shut down. Power is cubed, so a wind of 14 MPH provides 100KWH from a 1 MWH system.

Wind turbine design Typical modern wind turbines have diameters of 40 to 90 metres (130 to 300 ft) and are rated between 500 kW and 2 MW. As of 2014 the most powerful turbine, the Vestas V-164, is rated at 8 MW and has a rotor diameter of 164m.ll wind turbines are designed for a maximum wind speed, called the survival speed, above which they will be damaged. The survival speed of commercial wind turbines is in the range of 40 m/s (144 km/h, 89 MPH) to 72 m/s (259 km/h, 161 MPH). The most common survival speed is 60 m/s (216 km/h, 134 MPH).

How Much Power will a Wind Turbine Produce The wind power at 10 mph with a given rotor size might be 100 watts but at 20 mph will be 800 watts. As the wind speed doubles, the wind power goes up by a factor of 8. The next consideration is called Coefficient of Performance (Cp). Sometimes this is referred to as efficiency.

How Wind Energy Works Several factors can affect wind speed and the ability of a turbine to generate more power. For example, wind speed increases as the height from the ground increases. If wind speed at 10 meters off the ground is 6 m/s, it will be about 7.5 m/s at a height of 50 meters.his, and the fact that wind power is one of the most abundant and increasingly cost-competitive energy resources, makes it a viable alternative to the fossil fuels that harm our health and threaten the environment. Wind energy is the fastest growing source of electricity in the world.

Wind turbine In Denmark by 1900, there were about 2500 windmills for mechanical loads such as pumps and mills, producing an estimated combined peak power of about 30 MW. The largest machines were on 24-meter (79 ft) towers with four-bladed 23-meter (75 ft) diameter rotors. 1.5 MW wind turbine of a type frequently seen in the United States has a tower 80 meters (260 ft) high. The rotor assembly (blades and hub) weighs 22,000 kilograms (48,000 lb). The nacelle, which contains the generator component, weighs 52,000 kilograms (115,000 lb).

Animation: How a Wind Turbine Works A wind turbine works on a simple principle. This animation shows how energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy.

- When it comes to size, bigger is better. The bigger the wind turbine, the more wind it reaches and the more electricity it produces. Wind turbines used for large-scale wind farms come in various sizes, but are usually approximately 13 feet wide at the base, and between 230 and 265 feet tall at the hub.

How Wind Works The turbine’s blades are similar to the propeller blades on an airplane. The hub of the turbine is rotated as the rotor blades generate lift from the passing wind. This rotating action then turns a generator, which creates electricity.

- Turbine Efficiency If the turbine could convert all the wind's power to mechanical power we would say it was 100% efficient. But as you probably know, the real world is never so generous. To even achieve 50% is unlikely, and would be a very efficient machine.

- The bigger the rotor blades, the more energy they can capture from the wind. The giant blades (typically 70 m or 230 feet in diameter, which is about 30 times the wingspan of an eagle) multiply the wind's force like a wheel and axle, so even a gentle breeze is enough to make the outer edges of the blades turn around.he same thing happens in a wind turbine, only the dynamo generator is driven by the turbine's rotor blades instead of by a bicycle wheel, and the lamp is a light in someone's home dozens of miles away.

Wind turbines Photo: Left: A small wind farm in Colorado, United States. These are relatively small turbines: each one produces about 700kW of energy (enough to supply about 400 homes). The turbines are 79m (260ft) high (from the ground to the very top of the rotors) and the rotors themselves are 48.5m (159ft) in diameter. The top part of each turbine (called the nacelle) rotates on the tower beneath so the spinning blades are always facing directly into the wind.

How much energy can one wind turbine generate in one day? More general: This depends on the size of the turbine and the wind resource. A single 1MW turbine operating at a 45% production rate will generate about 3.9 milion kW of electricity in a year. This would be enough to meet the needs of about 500 households per year.t is not the fault of the system, but average winds. Wind Turbines are rated at between 25 and 28 MPH winds.

- Typically 1% of a wind farm is used for the turbines, access paths and electrical infrastructure. The remainder of the land can be used for its natural activities such as growing crops and farming. How fast do the blades on a wind turbine turn? Typically, assuming a steady speed, the blades on a wind turbine can rotate at 15-20 revolutions per minute. How much of the time do wind turbines generate electricity? Wind turbines generally generate electricity 70-85% of the time. On average a standard wind turbine is deemed to generate approximately 30% of its maximum theoretical capacity which is called the load factor.

1,000-Foot-Tall Wind Turbine To Be Erected The wind turbine has an electricity generation capacity of 40 MW, which means that it has a very high power-to-height ratio, and can power a whopping 13,333 homes by itself, at peak power production. It costs $48 million to manufacture. This translates to a reasonable cost of $1.20 per watt of generation capacity.

Wind turbines kill up to 39 million birds a year! Obviously, taller turbines with longer blades and faster blade tip speeds will catapult stricken birds much further. Figure 1 shows how a turbine 2.5 times larger will result in an average carcass distance of 372 feet (113.5 meters) from the tower. The wind industry is acutely aware of this. That is why it has restricted search areas to 165 feet (50 meters) around its bigger turbines.
