Wind turbines convert the kinetic energy in moving air into rotational energy, which in turn is converted to electricity. Since wind speeds vary from month to month and second to second, the amount of electricity wind can make varies constantly. Sometimes a wind turbine will make no power at all. This variability does affect the value of the wind power……Editor’s Note: This ‘fact sheet’ is, on the whole, a comparatively fair report. The definitions provided for capacity factor, efficiency, reliability, dispatchability, and availability are useful. Its discussion of back-up generation, marginal emissions and Germany & Denmark, however, is disingenuous as is, to a lesser degree, its discussion of capacity factor and availability. IWA's comments (updated October '06) on these issues follow selected extracts from the 'fact sheet' below.

This document has been prepared by Terry Matilsky, Professor of Physics at Rutgers University. For almost 40 years, he has been funded by NASA and other federal agencies to do data analysis from various scientific satellites; to examine what information tells us about a phenomena, and draw rational and solid, scientific conclusions from them.
"After the wind resource and project site have been determined and the community outreach effort has been started, the next step is to apply for the necessary permits. The primary permits needed to construct most community– scale wind power projects will be the local permits: building, zoning, and/or conservation, as applicable to a specific site. Additionally, the project will need to be filed with the FAA and with the operators of the New England electrical grid. Depending on the site, other permits may come into play. This document outlines these basic permits and also lists other authorities that may have jurisdiction over community–scale wind power projects. This fact-sheet focuses on land–based commuity scale wind power projects with medium or large turbines."
