"When storms come, some build walls, some are thrown by the wind. Others build wind mills." - Lao TzuUneven heating of the Earth's surface causes the wind to blow. Many societies have long taken advantage of this energy to travel great distances and perform diverse tasks such as grinding grains, sawing and pumping water. Modern wind turbines using advanced technologies are able to produce electricity for homes, businesses, and even utilities.

Wind power is the fastest growing of the renewable energies. Large machines called turbines have long blades that are turned by the wind. As the blades turn electricity is generated. This electricity can then move down power lines and to your home. Oklahoma is ranked 9th in the country for wind power. The state's first commercial wind farm came online in 2003 and there are 17 wind farms in our state, clustered in the western half of the state, most near Woodward, Elk City and Lawton, where the wind energy potential is greatest. The electricity generated by these wind farms can power 175,000 homes. In 2011 Oklahoma produced more than 2,100 megawatts of electricity from wind. That accounts for about 7.1 percent of the power produced in the state. Nationwide large wind turbines on farms and ranches average 1,035 kW in generating capacity.
