Development in the 20th century might be usefully divided into the periods: • 1900–1973, when widespread use of individual wind generators competed against fossil fuel plants and centrally-generated electricity• 1973–onward, when the spurred investigation of non-petroleum energy sources.

Why do people use wind energy?
Ingrained in our world history, people have been using wind energy for thousands of years. As early as 5,000 BC, wind was used to propel boats along the river Nile. In 200 BC, wind-powered water pumps were being integrated in China and windmills were grinding grain in the Middle East.
How did colonists use wind turbines?
American colonists used windmills to grind grain, pump water, and cut wood at sawmills. Homesteaders and ranchers installed thousands of wind pumps as they settled the western United States. In the late 1800s and early 1900s, small wind-electric generators (wind turbines) were also widely used.
How did US government support wind turbines?
The US federal government supported research and development of large wind turbines. In the early 1980s, thousands of wind turbines were installed in California, largely because of federal and state policies that encouraged the use of renewable energy sources.
How were wind turbines used in the 1970s?
Small wind turbines were used as electricity in remote and rural areas. 1970s - Oil shortages changed the energy environment for the US and the world. The oil shortages created an interest in developing ways to use alternative energy sources, such as wind energy, to generate electricity.
Engineering, procurement, and construction (EPC) contracts (a type of contract) are a form of contract used to undertake construction works by the private sector on large-scale and complex infrastructure projects. They may follow a (FEED) contract.
