Darmstadt Manifesto

Darmstadt_manifesto_thumb Issued on September 1, 1998 by The Initiative Group and signed by more than 100 German University professors, the Darmstadt Manifesto On the Exploitation of Wind Energy in Germany demands the withdrawal of all direct and indirect subsidies in order to put a stop to the exploitation of wind energy. The manifesto claims that the exploitation of wind energy promotes the type of technology which is of no significance whatever for the purpose of supplying energy, saving resources and protecting the climate. The money could be put to far more effective use in increasing the efficiency of power stations, in ensuring effective energy consumption and in funding scientific research into fundamental principles in the field of energy. The Darmstadt Manifesto is directed in particular at politicians, environmental organisations and the media.

Wind Energy Potential in the United States

Nwtc_about_the_program_-_wind_resource_-_wind_energy_potential_thumb 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 Power: Capacity Factor, Intermittency, and what happens when the wind doesn’t blow?

Rerl_fact_sheet_2a_capacity_factor_thumb 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.
