Humans have been using wind
power for at least 5,500 years to propel sailboats and sailing ships,
and architects have used wind-driven natural ventilation in buildings since
similarly ancient times. Windmills have been used for irrigation pumping and
for milling grain since the 7th century AD in what is now Afghanistan, Iran and
Pakistan.
In the United States, the
development of the "water-pumping windmill" was the major factor in
allowing the farming and ranching of vast areas otherwise devoid of readily
accessible water. Windpumps contributed to the expansion of rail transport
systems throughout the world, by pumping water from water wells for the steam
locomotives. The multi-bladed wind turbine atop a lattice tower made of wood or
steel was, for many years, a fixture of the landscape throughout rural America.
When fitted with generators and battery banks, small wind machines provided
electricity to isolated farms.
In July 1887, a Scottish
academic, Professor James Blyth, undertook wind power experiments that
culminated in a UK patent in 1891. In the United States, Charles F. Brush
produced electricity using a wind powered machine, starting in the winter of
1887-1888, which powered his home and laboratory until about 1900. In the
1890s, the Danish scientist and inventor Poul la Cour constructed wind turbines
to generate electricity, which was then used to produce hydrogen. These were
the first of what was to become the modern form of wind turbine.
Small wind turbines (wind
power plant) for lighting of isolated rural buildings were widespread in
the first part of the 20th century. Larger wind power plant units
intended for connection to a distribution network were tried at several
locations including Balaklava USSR in 1931 and in a 1.25 megawatt (MW)
experimental unit in Vermont in 1941.
The modern wind power
plant industry began in 1979 with the serial production of wind
turbines by Danish manufacturers Kuriant, Vestas, Nordtank, and Bonus. These
early turbines were small by today's standards, with capacities of 20–30 kW
each. Since then, they have increased greatly in size, with the Enercon E-126
capable of delivering up to 7 MW, while wind turbine production has expanded to
many countries.
