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).

A: In the garden
of his holiday
cottage at Marykirk in Kincardineshire.

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.

A: National electrical networks.
How does the atmosphere act as a thermal
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,
such as Renewables.ninja provide what?
-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.
