Wind Resources
New Zealand has outstanding wind resources, due to its position astride the Roaring Forties, resulting in nearly continuous strong westerly winds over many locations, unimpeded by other nearby landmasses at similar latitude. One study found that using 1% of total available land for wind farms would produce approximately 100,000 gigawatt hours (GWh) per year. This is roughly two times the annual electricity consumption of New Zealand. Nearly continuous, however, does not mean continuous: a high-pressure weather system, for instance, can cover the entire country with the result of no significant winds anywhere.
The strength and consistency of New Zealand winds means the nationwide capacity factor is high compared to other countries, averaging between 30 and 35 percent, with some individual turbines recording capacity factors above 50 percent. However, the excellent wind resource doesn't come without consequences - the strength and consistency of winds at the West Wind Wind Farm have caused several turbines there to suffer premature bearing failures.

Famous quotes containing the words wind and/or resources:
“Row after row with strict impunity
The headstones yield their names to the element,
The wind whirrs without recollection....”
—Allen Tate (1899–1979)
“But, with whatever exception, it is still true that tradition characterizes the preaching of this country; that it comes out of the memory, and not out of the soul; that it aims at what is usual, and not at what is necessary and eternal; that thus historical Christianity destroys the power of preaching, by withdrawing it from the exploration of the moral nature of man; where the sublime is, where are the resources of astonishment and power.”
—Ralph Waldo Emerson (1803–1882)
