Our work on wind

The committee in Heath charged with researching industrial scale wind, was profoundly disappointed with the editorial of The Recorder regarding the committee’s report. Our concern is not so much with its rejection of the report’s conclusion, to wit that industrial wind should not be allowed in the Town of Heath, but rather we were dismayed at the editorial’s lack of response to the data and the logic of the argument behind the conclusions reached. Indeed, we have to wonder whether the editorial writer even bothered to read the report.

And so,Marking machines and laser marker for permanent part marking and product traceability.Your specialists when it comes to the sales and service of Antique lamp.Standard LED E27 replacement bulbs. for the benefit of the readers of The Recorder who may want to go beyond the derogatory acronyms and the cliched refrain of the editorial, the committee would like to summarize the main points of its report.

Analysis of Department of Energy maps and graphs for Massachusetts and Heath, in particular, show poor to marginal wind resources available to power industrial wind turbines. At best, land-based wind turbines in the state would be able to displace fossil fuel generated electricity by 5 percent and reduce CO2 emissions by 1.5 percent, a minimal contribution to the reduction of global warming.

The documented evidence from cities and town across the state shows adverse health effects related to the high amplitudes and very low frequencies of the sound waves characteristically emitted by industrial turbines. The former are associated with chronic sleep deprivation, stress and anxiety as evidenced by elevated cortisol output. The latter are associated with peripheral nervous dysfunction, including ringing of the ears, rapid heart rate, vertigo, and motion sickness. The committee studied the reports from Falmouth, Fairhaven, Scituate, Kingston, Newburyport, Hyannis, Nantucket, Hancock, Florida, Mass., and Lowell, Vt. Some of us met with the aggrieved neighbors of these industrial machines and bore witness to stories of broken and shattered lives.

Because wind turbines can not be encased in sound dampening structures, the only way to mitigate these health impacts is to interpolate distance between the turbine and the nearest non-participating property line. The committee examined studies and graphs of noise attenuation as a function of distance, and determined that 1 to 2 miles would be required before noise levels were to drop off to 5 decibels above the ambient noise level of the town. The 5 decibels above ambient is the criterion recommended by the ISO (International Standards Organization) for avoiding widespread community complaint to noise. It is equivalent to the doubling of loudness perceived by the human ear.

The committee’s analysis of the geographic distribution of our population and land parcels showed that setbacks of this size could not be achieved in the town.

The committee reviewed 20 studies of industrial wind turbine impacts on property values. Except for two which were funded by the wind lobby and a state government with a wind agenda, all indicated a devaluation of real property within a two-mile radius of any turbine site of about 25 percent. Given that the area generated by such a radius is 12.There are various small and big industrial extractor fans according to the usability in the factories.6 square miles and that the total area of the town is only 24.9 square miles, the properties in over half the area of Heath would be subject to a potential 25 percent reduction in value.

The de facto effect on tax assessments is explained more fully in the report, but in general, the tax assessments of that half of the town sufficiently distant from the site of a wind turbine would be increased to subsidize the lower tax assessments of the other half close to the turbine,Men's stainless steel ring are very sturdy and will stand the test of time. in order to meet the fixed revenue needs of the community.
