These resource documents are provided to assist anyone wishing to research the issue of industrial wind power and the impacts of its development. The information should be evaluated by each reader to come to their own conclusions about the many areas of debate.
ABSTRACT We compare three technologies that produce electricity in the United States: wind, solar, and combined-cycle gas turbines (CCGT). We use the 2016 electric utility database compiled by the U.S. Energy Information Administration (EIA). That database has the advantage of being based on a census of U.S. power plants rather than sampling, as well as excluding any subsidies received by the power plants. We show the cost savings achieved when there is a shift between coal-fired generation and generation by . . .More »

Wind energy is known to many as a “green” solution to climate change. But wind energy is really just another form of industrial development, and we can’t ignore its costs and consequences to wildlife and their habitats. As Director of ABC’s Bird-Smart Wind Energy Campaign, I often encounter several common misconceptions about wind development. Read on to learn more about the real impact of unchecked wind energy development on birds and other wildlife. Myth 1: Wind turbines are “green” energy . . .More »
On our analysis, a number of propositions emerge from the medical and scientific evidence. Some of those propositions had unanimous support by the relevant experts, and others had the support of most. The propositions which we understand have unanimous support from the relevant experts or are not contested include the following: Wind turbines emit sound, some of which is audible, and some of which is inaudible (infrasound); There are numerous recorded instances of WTN exceeding 40 dB(A) (which is a . . .More »
Abstract – The unsteady nature of wind turbine noise is a major reason for annoyance. The variation of far-field sound pressure levels is not only caused by the continuous change in wind turbine noise source levels but also by the unsteady flow field and the ground characteristics between the turbine and receiver. To take these phenomena into account, a consistent numerical technique that models the sound propagation from the source to receiver is developed. Large eddy simulation with an actuator . . .More »
