History of Wind Energy
Since early recorded history, people have harnessed the energy of the wind. Wind energy propelled boats along the Nile River as early as 5000 B.C. By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East.
New ways of using the energy of the wind eventually spread around the world. By the 11thcentury, people in the Middle East used windmills extensively for food production. Returning merchants and crusaders carried this idea back to Europe. The Dutch refined the windmill and adapted it for draining lakes and marshes in the Rhine River Delta. When settlers took this technology to the New World in the late 19th century, they began using windmills to pump water for farms and ranches and later to generate electricity for homes and industry.
American colonists used windmills to grind wheat and corn, to pump water and to cut wood at sawmills. With the development of electric power, wind power found new applications in lighting buildings remotely from centrally generated power. Throughout the 20th century, small wind plants, suitable for farms and residences, and larger utility-scale wind farms that could be connected to electricity grids were developed.
During World War II, the largest wind turbine known in the 1940s, a 1.25-megawatt turbine that sat on a Vermont hilltop known as Grandpa’s Knob, fed electric power to the local utility network. Wind electric turbines persisted in Denmark into the 1950s but were ultimately sidelined due to the availability of cheap oil and low energy prices.
The oil shortages of the 1970s changed the energy picture for the U.S. and the world. It created an interest in alternative energy sources, paving the way for the re-entry of the wind turbine to generate electricity.
From 1974 through the mid-1980s, the U.S. government worked with industry to advance the technology and enable development and deployment of large commercial wind turbines. Large-scale research wind turbines were developed under a program overseen by the National Aeronautics and Space Administration to create a utility-scale wind turbine industry in the United States. With funding from the National Science Foundation and later the U.S. Department of Energy, 13 experimental turbines were put into operation using four major wind turbine designs. This research and development program pioneered many of the multi-megawatt turbine technologies in use today. The large wind turbines developed under this program set several world records for diameter and power output.
In the 1980s and early 1990s, low oil prices threatened to make electricity from wind power uneconomical. But in the 1980s wind energy flourished in California partly because of federal and state tax incentives that encouraged renewable energy sources. These incentives funded the first major use of wind power for utility electricity. The turbines, clustered in large wind resource areas such as Altamont Pass, would be considered small and uneconomical by modern wind farm development standards.
While wind energy’s growth in the U.S. slowed dramatically after tax incentives ended in the late 1980s, wind energy continued to grow in Europe, in part due to a renewed concern for the environment in response to scientific studies indicating potential changes to the global climate if the use of fossil fuels continues to increase.
Today, wind-powered generators operate in every size range, from small turbines for battery charging at isolated residences to large, near-gigawatt-size offshore wind farms that provide electricity to national electric transmission systems.

American Wind Power Center Museum
Most of the thousands of windmills used from the late 1800s and early 1900s have been lost, but the American Wind Power Center and Museum in Lubbock, Texas, houses more than100 rare and unique windmills. The Center is internationally recognized as the place to observe and photograph windmills in their natural setting. The Center also serves as the premier educational facility where the windmill’s heritage is taught, seen and heard. Complementing the many windmills is a large collection of photographs, drawings, and models in the Windmiller’s Art Gallery and other rare collections of windmill artifacts. The WINDSMITH museum store is also located in the building, specializing in a unique variety of windmill-related keepsakes.
