By John Droz, Jr. -- December 8, 2010 14 Comments[Editor note: Part II’s video on Jane talking about wind energy with her town supervisor is tomorrow.]
In my thirty plus years of working on environmental issues, I’ve learned a few things. One is that our “representatives” are often anything but. Another is that government bureaucrats have little interest in taking initiative, no matter how much sense it might make.
Yet another is that “environmental” organizations are much less interested in the environment then they might lead you to believe.
Yet still another insight is that active support from a sufficient number of citizens can be enough to offset these other liabilities. Put another way, if we do not get sufficient support from fellow citizens, our campaign objective has little chance for success. Phrased differently: the success of our campaign has more to do with the support we get, than the merits of what we are trying to do.…

By Edgar Gaertner -- December 1, 2010 17 CommentsThousands of bureaucrats are at another cushy climate confab–this time in Cancun–while Senators Bingaman, Brownback and Reid are contemplating how to ram a federal renewable energy quota through a lame-duck session. Their prospects are not good, which should give them more time to consider the experiences of Europe and windpower. The results of this experiment in energy coercion are humbling.
Germany, specifically, is in the throes of a windpower boondoggle that should be heard the world over. The general lesson is that energy forcing brings with it technological risk that must be factored into the public policy equation.
A North Sea Boondoggle
Barely two months after the inauguration ceremony for Germany’s first pilot offshore wind farm, “Alpha Ventus” in the North Sea, all six of the newly installed wind turbines were completely idle, due to gearbox damage.…

By Kent Hawkins -- November 30, 2010 4 CommentsPart I yesterday introduced the latest version of the Calculator (14.2), which continues to illustrate the futility of wind as a means of reducing fossil fuel consumption and CO2 emissions. This post provides more detail about the approach taken by the Calculator.
As important as the subject is, there are no extensive analyses of real-time information (finely grained time intervals for long periods of time) assessing all the variables affecting electricity system behaviour as wind penetration increases. Existing analyses have some or many of the following important limiting characteristics (not necessarily an exhaustive list):
· Are based solely on annual electricity production and annual averages (even statistical averaging is suspect in terms of real-time operation) of electricity generation.
· Use unrealistically high wind capacity factors, including offshore projections, which in practice deliver at about the same capacity factor as assumed at the high end for onshore.…

By Kent Hawkins -- November 29, 2010 25 Comments[Editor note: Kent Hawkins has been at the forefront of devising a model (the Calculator) to estimate the lost wind-related emission reductions due to the fact that backup fossil-fuel generation (to firm wind) must operate less efficiently. This two-part series (today and tomorrow) provides Mr. Hawkins’ latest thinking. While technical, the Calculator is a very important line of analysis that will continue to be revised by its open-minded author. So critical comments are especially welcome.]
There is no convincing proof of the ability of utility-scale wind electricity generation to provide any of the incredible benefits claimed for it. In light of the massive costs (hundreds of $billions) of the extensive implementations projected by some governments, and equally large changes to electricity grids required to support wind’s ineffectiveness, it seems reasonable to expect that such claims be properly substantiated beforehand.…
