This latest surprise for global energy activists just arrived in the Institute of Electrical and Electronic Engineers on line journal, the IEEE Spectrum.
Quite simply, the IEEE cites a new report from France that indicates average wind speeds around the Northern Hemisphere are dropping.
Because wind energy varies as the square of the wind speed, when that speed drops even a small amount, the ability to extract energy from the wind drops much more. The article indicates new wind farms in China may produce 14 percent less than the original designs anticipated due to anticipated further wind speed decays.
Of course, experts have already indicated to me that Kentucky has few sites suitable for economical wind farm operations in the first place. So, Kentucky is already left out of this much hyped answer to our energy needs.
Now, it looks like the wind energy answer for a lot of other areas could be getting blown away, as well.
Maybe coal won’t be dead, after all.
