Wind, the movement of air, is a meteorological phenomenon that plays an integral part in activities ranging from the production of electricity to the creation of myth. It is one of the natural elemental forces of the world. Wind can be felt, and its effects can be observed and measured, but wind itself cannot be seen. It is an invisible force that assists in weather change, and provides power to machines that take advantage of it.

There are many myths and stories behind the power of wind;[1] it seemingly comes from nowhere, but is recognized as an invisible force. Polytheistic religions often attributed the power of wind to a deity, or a servant.

## Causes[edit]

Wind is actually the motion of air, produced by a change in heat on the Earth's surface. As different parts of the Earth heat up, the air in those parts rises as the cooler parts cause air to sink. This change in temperature generates the motion of air.

## Effects[edit]

Next to earthquakes and floods, wind can be the cause of some of the worst types of natural disasters. Typhoons, hurricanes, tornadoes, and dust storms are all a side effect of massive wind currents, causing some of the greatest amounts of property damage.

## Exploitation[edit]

Since the dawn of the windmill, the ability to convert wind from a force to a source of work has evolved into the ability to exploit wind currents into a viable source of alternative energy. Large electric-windmill farms have been set up in mountainous areas to generate sufficient electricity to subsidise the electrical need of small cities. The advantage of this energy source is that it is non-polluting and "renewable" (in the sense that it never really expires; the amount of energy throughput is dependant on weather conditions).[2][3]
