of vertical axis wind turbines have recently gained attention because of their potential to harness wind power in new locations and reduce energy loss through transmission. Urban wind generation involves installing wind turbines in the urban environment. These can be mounted on freestanding poles such as a light post, or on a rooftop.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:

1.3 How to design a good small vertical-axis wind turbine 1.3.1 Although different from a HAWT, the core technology of a VAWT remains a wind mill structure with blades. After choosing an airfoil, it is necessary to calculate a concave orientation, angle, width, and quantity because each of these factors determines the performance of the VAWT.

A modern wind turbine begins to produce electricity when wind speed reaches 6-9 miles per hour (mph) and has to shut down if it exceeds 55 mph (88.5 kilometers per hour) when its mechanism would be in danger of sustaining damage. So, while they can generate electricity for much of the time, there are other times they have to be shut down.

Vertical-axis wind turbines, although output is lower and a lower height means wind speeds are generally lower, offer easier access to mechanical parts. Wind from any direction moves the turbine and the vertical axis enables the blades, spinning horizontally to the ground, to move when the wind blows from any direction.

There are two main types of wind turbines. The two general categories for wind turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and

For the 4 kW wind turbine, we'll assume the turbine is 40m high. Average wind speed is about 6.5 m/s, giving an average power output of 900W (from power curve). Average energy per day is 900W x 24h = 21,600 Wh or 21.6 kWh. Obviously the relative energy outputs are very dependent on location.

Wind turbines are advertised with a rated power. Small turbines, like those you'd see on a roof, are generally rated at 400W to 1kW. So you might do a quick mental calculation and guess that the 1kW turbine would generate 24 kWh of energy each day (1kW x 24 hours.) Well, that would be true if the wind were blowing constantly at the rated wind ...

The horizontal-axis or vertical windmill (so called due to the plane of the movement of its sails) is a development of the 12th century, first used in northwestern Europe, in the triangle of northern France, eastern England and Flanders. It is unclear whether the vertical windmill was influenced by the introduction of the horizontal windmill to Southern Europe in the preceding century.
