The price of fossil fuels is increasing at an worrying rate and in addition they will not last forever. In order to tackle the problem it is imperative that we begin to use the many renewable energy assets provided to us from the Earth. Renewable resources such as solar power, tidal power, wave power along with wind power. Breeze is everywhere but how do we use it to create power? The concept of wind flow power goes back with regard to 1000’s of years and was utilized to power boats not to mention sail boats continue to be in use today despite the fact that generally not on exactly the same scale. Vertical-axis wind mills were used in Persia as normal water pumps and to work corn and it is considered that these devices could have been utilised as early as the 7th century.

The wind electrical power we are perhaps far more familiar with would be the horizontal-axis windmill, which has huge sails fitted about a central axel. Since the wind blows these kinds of sails they turn the actual axel and they could be employed to drive the action of a mechanism. Among this would be in a flour generator where the sails would be accustomed to drive large milling stones that would mash grains into flour. Even though technology has moved on the key is exactly the same right now as it was 100’s of years ago. The difference would be that the wind is driving blades rather than sails which blades in turn travel a turbine who makes electricity.

Wind electrical power is a useful renewable energy, however like all alternative energy sources cannot be viewed as the magic bullet to the way forward for our energy needs. It needs to be integrated with other useful renewable energy sources as a way to develop a stable lasting supply of power.
