The idea to convert wind to power to do things is very old, used in Persia as early as 200 BC. The modern wind turbine is typically a three-bladed structure that is 200 to 300 feet in height. Wind turbines differ from wind mills. Wind mills are used to pump water or to grind grains; wind turbines generate electricity. This highly efficient machine is computer-controlled, with the blades spinning up to six times the actual speed of the wind.
The United States is Behind Europe in Wind Power
In terms of electricity production, the United States is way behind other countries. Denmark leads the world with 19% of its electricity being produced by wind turbines, followed by Spain with 9%. The United States produces less than 1% of its electricty from wind turbines, in spite of the fact that we have one of the best "wind belts" in the world.
Why Does this Matter?
Although wind turbines are not cheap to install, once they are producing electricity they pay for themselves in about 6 years. What makes wind power so unique is that it can't be held hostage by unfriendly countries, it will never run out, it does not produce pollution, it can't be "outsourced" to other countries and it keeps dollars and jobs here in the United States.
