In the industrial arena, the term power generation most typically refers to the production of electrical or mechanical power via any of several energy conversion processes. Early examples of practical power generation devices include water-wheel-powered mills for grinding grain, which were reportedly used as early as 100 BC in the Balkans and areas of the Middle East, and wind-powered mills, which were widely used as early as the tenth century in the Middle East. 

Cut-in wind speed is the minimum wind speed at which the generator commences the generation of power. At this speed the brakes release and the prime mover (blades) starts rotating.

The carbon footprint of electricity generation through RES (Renewable Energy Systems) are described in this section. Elydro-electricity is described first, and then wind power, followed by bioenergy systems and solar energy. 

Approximately 10% of U.S. electrical energy is produced by hydroelectric dams.6 Although there are few economic and environmentally acceptable dam sites remaining, in some places it is possible to use wind power, or perhaps even the ocean tides, to generate electricity. Here the opportunity for chemists and chemical engineers is the invention and production of modern materials that can make such approaches possible.

Renewable energy is about 13% of the world s energy while fossil fuels make up 80% and nuclear power 7%. Wind power has become a major part of power generation in Europe, with 20 to 40% of power loads in parts of Germany, Denmark, and Spain.
