Windmills

Windmill pump on Crete A very small part of the irrigated area of the world makes use of wind-power. In most places, the mean wind-speed is too low, so it will not turn the sails. Along the coast, the right wind speed occurs for windmills. This is the case on the islands in the Mediterranean Sea. On Crete, there is the Valley of the Ten Thousand Mills. Today, even here petrol has replaced wind-power. Very few (1990) are still working. [63]
