Wind Energy

Wind has been used to move boats with cloth sails. The first windmills seem to have been used in Persia around AD 70. The sails turned horizontally, and were connected directly to the millstones used to grind grain. 

Wind is an excellent way to produce electricity and pump water from wells, provided there is wind available on site. Windmills are best located along coastlines, on hills, or in other areas where high winds are commonly found. 

On the Greek island of Crete, windmills have been used for centuries for irrigation purposes. The type of windmill used today is an improved version of the traditional ones. These mills are simple to build, to operate and to maintain. 

In the Netherlands, wind power was used to pump water from the land as a vital part of reclamation schemes from the early fifteenth century onwards. 

The majority of windmills introduced in Africa are high-tech and very expensive. These mills are generally used for pumping water, and in some cases for producing electricity. In coastal areas, harnessing the abundant wind energy in order to irrigate land is an efficient way to alleviate the impacts of frequent drought, the great enemy of farmers.

  • In coastal and mountain areas, harnessing the abundant wind energy for irrigation is an efficient way to fight droughts, and increase food production;
  • In Africa, wind power could play a useful role for water supply and irrigation (wind pumps) and electrical generation (wind turbines or generators);
  • Wind power is a mature renewable energy technology that could be used for small and large-scale electricity generation; 
  • There is substantial potential for deployment of this technology in Africa, especially along the coastal and mountain areas.
