The workings of a wind system are very dependent on the average wind speed in the area, and to a lesser extent, the cost of purchasing electricity. As a general rule of thumb, if mathematics are a concern, a turbine owner should have at least a 10 mph average wind speed and be cost at least $.10 cents/kWh for electricity.
Wind turbines produce no pollution and by using wind power you will be offsetting pollution that would have been generated by your utility company. Over its life, a small residential wind turbine can offset approximately 1.2 tons of air pollutants and 200 tons of greenhouse gases (carbon dioxide and other gases which cause climate change).
Residential wind turbines can be of various sizes, but if your property enjoys the cool Caribbean breezes, there is no doubt wind energy is suitable for you.

Wind turbines are a great addition to a solar system as they produce 24 hrs a day on most days for properties on the windward coasts of the islands; properties located in the heights get venture effects and therefore could enjoy high wind energy production.
How it Works
The wind blows on the blades and makes them turn.
The blades turns a shaft inside the nacelle (the box at the top of the turbine)
The shaft goes into a gearbox which increases the rotation speed enough for…
The generator, which uses magnetic fields to convert the rotational energy into electrical energy. These are similar to those found in normal power stations.
Wind Power Diagram
The power output goes to a transformer, which converts the electricity coming out of the generator at around 700 Volts (V) to the right voltage for distribution system, typically 33,000 Volts.
Instruments to measure the wind speed and direction are fitted on top of the nacelle. When the wind changes direction motors turn the nacelle, and the blades along with it, around to face the wind. The nacelle is also fitted with brakes, so that the turbine can be switched off in very high winds, like during storms. This prevents the turbine being damaged. All this information is recorded by computers and transmitted to a control centre, which means that people don’t have to visit the turbine very often, just occasionally for a mechanical check.
