With California's energy crisis in the headlines, advocates of wind power are hoping it will mean a major boost for this source of clean, alternative energy. But they face a previously underappreciated problem: bugs.
Although the nation's wind potential is very large, only part of it can be exploited economically. The economic viability of wind power will vary from utility to utility. Important factors not addressed in this study that influence land availability and wind electric potential include production/demand match (seasonal and daily), transmission and access constraints, public acceptance, and other technological and institutional constraints. Editor's Note: Though dated, this is a worthwhile read if read carefully.
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.
