Remote systems are small, relatively cheap sources of energy. They are best suited for rural environments because they can be left unattended for long periods of time. Further, they can operate under harsh conditions, and thus have potential for powering extremely remote regions of the world.
The very nature of wind-powered generators makes them ideal to use in conjuction with other sources of energy. Wind and solar generators have been extremely successful as supplements to one another. The presence of the wind generator means that the other energy source does not have to be producing as much of the time.
Grid Connected systems are already in wide use in areas that are already hooked up to a utility grid. Their main use is as a supplement to other forms of energy. This is important because average wind turbines only generate electricity about 25% of the time.
Because individual wind-powered systems by themselves do not produce a great deal of energy, so-called "wind farms" have been developed. These collections of many wind generators gathered in one place provide a source of relatively high energy output.
