“Nevertheless, you’d think the Governor and others would be actively trying to make things better, rather than just pointing fingers. Well … they are making it worse by taking away the one alternative to electricity that can provide cooking and hot water and space heat and does so much more efficiently–natural gas.”
I sit here at my computer this morning after suffering through the latest “PSPS” (public safety power shutoff), which left me without electricity a total of ten full days in October. Kind of ironic given my 45+ years in energy policy–and frustrating too since this is less an Act of God than an Act of Man–or Government.
I understand the need to reduce fire risk in California’s hot dry climate where utilities (such as PG&E) need to de-energize power lines lest they spark when blown down or branches fall on them. …
Continue Reading“The description of wind turbine noise needs a terminological shift. The language should be pulsations at an infrasound rate with modulation of the entire signal at an infrasound rate (as in sensation detected by the ear).” [Cooper, below]
Q: You referred earlier [yesterday] to your second paper at the ICA that is linked to the synthesis paper. Maybe my question on ILFN ties in with the paper on Amplitude Modulation that raises questions as to terminology?
Cooper: Yes. The second paper on amplitude modulation is very important. Because what people are calling AM (by reference to the dBA signal) is incorrect. An electrical engineer will tell you that AM is the modulation (variation in the amplitude) of a carrier frequency (being a high frequency) that is modulated at a lower rate.…

Last year, I interviewed acoustician Steven Cooper, AU on wind turbine health issues related to pulsation and low-frequency noise. “In general, wind farm applications claim that turbines do not generate any low-frequency, tonal, or impulsive characteristics,” he noted, “which is a matter disputed by residential receivers.”
What has developed in the last 20 months? In this two-part series (today and tomorrow), Mr. Cooper shares his most recent research and findings, which complement our current knowledge regarding the nature of “noise” impacts to real-time victims of wind power.
Mr. Cooper recently presented his new findings in Germany at the International Congress on Acoustics Conference.…
