Wind power has been used as long as humans have put “what” into the wind?
A: Sails.

For more than two millennia wind-powered machines have done what?
A: Ground grain and pumped water.

Wind power was widely available and not confined to what?

Wind-powered pumps drained the polders of what?
A: The Netherlands.

In arid regions such as the American mid-west or the Australian outback, wind pumps provided what for livestock?
A: Water.

Where was the first windmill used for the production of electric power was built?
A: In Scotland in July 1887.

Who built it?
A: Prof James Blyth of Anderson's College, Glasgow (the precursor of Strathclyde University).

Where was Blyth's 10 meters (33 ft) high, cloth-sailed wind turbine was installed?
A: In the garden of his holiday cottage at Marykirk in Kincardineshire.

What was it used for?
A: To charge accumulators developed by the Frenchman Camille Alphonse Faure, to power the lighting in the cottage.

This made it the first house in the world to have what?
A: To have its electric power supplied by wind power.

Blyth offered the surplus electric power to the people of Marykirk for what?
A: Lighting the main street.

Why did the people of Marykirk turn him down?
A: They thought electric power was "the work of the devil.

" He later built a wind turbine to supply emergency power to what?
A: The local Lunatic Asylum, Infirmary and Dispensary of Montrose.

Why did the invention not catch on?
A: The technology was not considered to be economically viable.

A: 12 kW.

The connected dynamo was used either to do what?
A: To either charge a bank of batteries or to operate up to 100 incandescent light bulbs, three arc lamps, and various motors in Brush's laboratory.

Today wind powered generators operate in every size range between tiny stations for battery charging at isolated residences, up to near-gigawatt sized offshore wind farms that provide electric power to what?
A: National electrical networks.

How does the atmosphere act as a thermal engine?
A: Absorbing heat at higher temperatures, releasing heat at lower temperatures.

Through wind resource assessment it is possible to provide estimates of what?
A: Wind power potential globally, by country or region, or for a specific site.

A global assessment of wind power potential is available via what?
A: The Global Wind Atlas provided by the Technical University of Denmark in partnership with the World Bank.

Unlike 'static' wind resource atlases which average estimates of wind speed and power density across multiple years, tools such as provide what?
A: Time-varying simulations of wind speed and power output from different wind turbine models at an hourly resolution.

More detailed, site specific assessments of wind resource potential can be obtained from whom?
A: Specialist commercial providers, and many of the larger wind developers will maintain in-house modeling capabilities.

The total amount of economically extractable power available from the wind is considerably more than what?
A: Present human power use from all sources.

The strength of wind varies, and an average value for a given location does not alone indicate what?
A: The amount of energy a wind turbine could produce there.

Different locations will have different what?
A: Different wind speed distributions.

A large wind farm may consist of how many individual wind turbines distributed over an extended area?
A: Several hundred.

What can the land between the turbines be used for?
A: Agricultural or other purposes.

Gansu Wind Farm, the largest wind farm in the world, has how turbines?
A: Several thousand.

A wind farm may also be located where?
A: Offshore.

Almost all large wind turbines have the same what?
A: Design; a horizontal axis wind turbine having an upwind rotor with three blades, attached to a nacelle on top of a tall tubular tower.

In general how much distance is set between each turbine in a fully developed wind farm?
A: 7 × Rotor Diameter of the Wind Turbine.
