They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power. For many centuries, people used windmills to make wheat into flour or get water from deep underground. When electricity was discovered in the late 1800s, people living in faraway areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were hardly used. During the 1970s, people started becoming more cared about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would run out one day. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind Question: When were the windmills used to produce electricity in some places? - In the 1100s - In the 1940s - In the 1970s - In the 1800s

Gradually, Saunders set up his mind on building up his body, increasing his speed and strength. At the age of 18, he ran his first marathon. The following year he met John Ridgway and started to work as a teacher at Ridgway's school of adventure in Scotland, where he learnt about Ridgway's cold--waterexploits.
