Windmills
The Past and Present History Of Windmills Windmills were first made over 2,000 years ago in ancient Persia (Iran), but were used to grind grain and other simple chores. Centuries later in Holland windmills were changed so that they could be turned to face the wind. The purpose of the windmill was still limited in the work it could do, as it was still used to grind grain and pull up water from wells. Yesterdays Windmills were primarily used to convert the winds kinetic energy into mechanical pow
The vertical and the horizontal axis windmills are the only two different windmills, while within each two groups there are many designs and forms of windmills. Windmills being used for electricity had just begun, and it quickly stopped when power lines were attached worldwide. Wind powered Electricity came back into the picture in the 1970's when oil shortages had people looking for alternative energy sources. Windmills weren't made to produce electricity until the 1930's. Windmills made in small towns not attached to any other power grids. The research is expensive and so far unsuccessful. Energy prices rose and the thoughts of "free" wind energy were in the air. Today there are several thousand windmills worldwide; the future of windmills will all depend on how much they are needed. To get the most energy from a windmill it had to be placed in a flat area with a lot of wind. In the 19th century windmills were brought to the United States for irrigation purposes. This very day Europeans are still developing the perfect windmills, which produce the most energy. The newest windmills use computers to turn them selves; the more expensive part of the windmills is in fact the computer. When first windmills were built they were very expensive, but after a lot of research was done towards the factors of windmills they were made to be much cheaper.
