The findings of the Intergovernmental Panel on Climate Change (IPCC) are often held up as representing “the consensus of scientists”—a pretty grandiose and presumptuous claim. And one that in recent days, weeks, and months, has been unraveling. So too, therefore, must all of the secondary assessments that are based on the IPCC findings—the most notable of which is the EPA’s Endangerment Finding—that “greenhouse gases taken in combination endanger both the public health and the public welfare of current and future generations.”
Recent events have shown, rather embarrassingly, that the IPCC is not “the” consensus of scientists, but rather the opinions of a few scientists (in some cases as few as one) in various subject areas whose consensus among themselves is then kludged together by the designers of the IPCC final product who a priori know what they want the ultimate outcome to be (that greenhouse gases are leading to dangerous climate change and need to be restricted).…

The project sponsors claim that they will provide enough energy to serve 235,000 households and reduce CO2 output by 1.5 million tonnes annually.
Part I demonstrated that the served-household claims is fanciful. In reality, no more than 49,000 households could be “supplied”, and these with only a minimal degree of assurance. Indeed, the wind project is more costly than a diesel backup scheme that would actually be capable of supplying reliable power to several hundred thousand households. The wind project is also three times more costly than a replacement of just 211 MW of older coal capacity with new technology that would provide a similar reduction in emissions, while supplying firm power to the NW Power Pool’s customers.…
Continue ReadingIn the midst of a bitter winter in North America and Europe, General Electric has announced a large wind project to be built in Oregon. Press reports in the Financial Times and USA Today describe a project of 338 machines of 2.5 MW each, giving a total capacity of 845 MW.
With power grids strained due to heating demand, increments to generating capacity are to be welcomed. But along with the usual hoopla about homes served and CO2 emissions savings, it is time for some “devil’s advocacy” by asking: – how much energy and capacity will this project really create? How much CO2 will be saved? And when the chips are down will consumers and grid operators be pleased that their funds have gone into wind rather than into some other generating source?…
