Hull benefits from REC sales not wind energy

To the editor, Boston Globe:

Although the wind turbines in Hull may generate electricity equivalent to 12% of the town's total electricity consumption (editorial, Oct. 1), that is unlikely to be the amount actually used.

Because the turbines' level of generation is in response to the wind rather than consumer demand, it would more often than not be well out of sync with the town's needs. Consequently, Hull's municipal utility -- without large-scale storage of the wind-generated energy -- must still have to buy just about as much power from the regional grid as before.

The money they are "saving" appears to be in fact income from the sale of renewable energy credits to Harvard, who thereby also pretend to be using the same wind power.

The twilight of industrial wind

Comment by Lyn Harrison, editor, Windpower Monthly, October 2006:

... witness the chaos in Spain caused by the sudden removal of the basis for wind power pricing, the overnight stop to the thriving wind market in the Netherlands, the fast approaching cliff-edge in Australia, Denmark's decline from role model to full-stop, and the perennial on-off market support in the US.

E. coli in spinach comes from factory farms

A commentary in the New York Times last week explained that factory-farmed cows, whether for meat or for milk, are the source of the E. coli strain that is so dangerous to humans. The strain thrives in an acidic environment (thus it is not killed in our stomachs), which has been created in the cow digestive tract by the industrial feed they are given. Their manure is therefore teeming with this dangerous strain of E. coli, and the manure pollutes the water table, streams, and rivers. The water used to rinse vegetable greens is polluted by the unnatural shit from industrial animal "farms."

[Update:  Grass-fed cows become colonized with E. coli O157:H7 at same rates as grain-fed cattle.]

Muir Trust warns of destruction of Scottish wild areas by wind power industry

The John Muir Trust believes

• Wild land should be conserved for nature and people for the benefit of present and future generations;


• Developments on core wild land, such as industrial-scale wind developments, are a major threat to our rapidly diminishing wild land;


• The best renewable energy options around wild land are small-scale, sensitively sited and adjacent to the communities directly benefiting from them, where the landscape impact is minimal;


• Large wind turbines, often 120 metres high (taller than the Forth Rail Bridge) grouped in clusters of up to 100, are totally unsuitable for Scotland’s finest landscapes;


• The intrusion is not just the turbines and pylons, but includes the access roads, concrete bases, and underground cables;


• Producing energy near to where it is consumed reduces the need for giant pylons through wild and scenic areas e.g. the proposed Beauly – Denny transmission upgrade;


• A recent study suggests far more eagles are at risk from wind developments than was previously thought so their habitat must be protected;


• It would be a tragedy to sacrifice wild land to major industrial developments.

Va. Dept. of Game and Inland Fisheries lays out wildlife case against wind power facility

As quoted at National Wind Watch (click the title of this post), where the entire letter is available:

"We feel this project presents an unacceptable risk to wildlife. We are particularly concerned with potential significant adverse impacts upon bats and birds. ... This project, and the conditions imposed by the State Corporation Commission, will set a precedent for all future wind energy projects in Virginia. Wind farms cannot be viewed as independent with regard to impacts upon wide-ranging migratory animals. We currently lack sufficient knowledge to absolutely determine the maximum fatality rates that can be tolerated at a given site without unacceptably impacting local or regional populations of sensitive species; but we are certain that high fatality rates at multiple sites across the landscape would pose an unacceptable risk, as do unmitigated fatalities of Endangered or Threatened species. ... In the case of this project, where wildlife losses potentially could be very substantial and significant, we must take a conservative approach to assessing risk and designing appropriate mitigation. The data needs for pre- and post-construction evaluation, monitoring, and mitigation should not be dictated by project applicants or consultants .... High fatality rates at this site would particularly be devastating to bats because of their reproductive strategy, which is atypical of a small mammal. ... They have small litters (typically one or two young), only one litter per year, and life expectancy of 12-15 years. With this strategy, the impact of the loss of individuals is much greater, especially within small populations. ... In addition to bats, we are concerned over potential eagle fatalities at this site. ... We have recommended that the applicant consult with the U.S. Fish and Wildlife Service concerning potential take of federal Endangered or Threatened species. We cannot authorize take of federally listed species. The applicant’s consultants have downplayed the potential for such take but, in our opinion, the evidence suggests a strong likelihood of take."

Bluff and bluster of wind supporters

A recent post on the National Forum of Australia (click the title):

One of the things that stands out about wind is its apparent inability to replace other sources. That is a big shortcoming. At least other sources -- renewable and otherwise -- produce useful electricity for the grid, so there is something against which to weigh the costs. As for the growth of the wind energy business, religious fundamentalism is growing around the world, too. That in itself does not make it right or true. The fact of the issue at hand is that the industry has yet to show any evidence of actual benefit from wind power on the grid. Their massive erections seem more like the giant statues on Rapa Nui, a desperate but very wrongheaded effort to fend off environmental disaster.

Irish wind energy planning guidelines

This is from section 5.6 of recent (June 2006) planning guidelines for wind energy from the Irish Department of the Environment, Heritage and Local Government.

In general, a lower fixed limit of 45dB(A)10 or a maximum increase of 5dB(A) above background noise at nearby noise sensitive locations is considered appropriate to provide protection to wind energy development neighbours. However, in very quiet areas, the use of a margin of 5dB(A) above background noise at nearby noise sensitive properties is not necessary to offer a reasonable degree of protection and may unduly restrict wind energy developments which should be recognised as having wider national and global benefits. Instead, in low noise environments where background noise is less than 30dB(A), it is recommended that the daytime level of the LA90, 10min of the wind energy development noise be limited to an absolute level within the range of 35-40dB(A).

Separate noise limits should apply for day-time and for night-time. During the night the protection of external amenity becomes less important and the emphasis should be on preventing sleep disturbance. A fixed limit of 43dB(A) will protect sleep inside properties during the night.

In general, noise is unlikely to be a significant problem where the distance from the nearest turbine to any noise sensitive property is more than 500 metres. Planning authorities may seek evidence that the type(s) of turbines proposed will use best current engineering practice in terms of noise creation and suppression.

Note they distinguish quieter rural areas from more suburban (I guess) areas. The allowable range for the noisier areas is from 45 dB to 5 dB above ambient. Obviously, this presumes an ambient level of at least 40 dB.

In quieter places (ambient less than 30 dB), they suggest an upper limit of 35-40 dB rather than a relative limit of 5 dB above ambient.

Their recommendation of 43 dB at night obviously applies to the noisier places, being meant as a lower maximum to allow sleep.

They also suggest that noise will not be a problem at a distance farther than 500 m, or just over 1,500 feet. (Note, however, the U.K. Noise Association's recommendation of a minimum distance of one mile from residences and the French Academy of Medicine's similar recommendation of 1.5 km.)

The 500 m limit is considered later (section 5.12) to also apply for shadow flicker, but they also state that flicker may still be a problem at a distance of 10 times the rotor diameter.

And here's an odd directive for maintaining "visual amenity": "Rotors should be kept rotating ..." (section 6.13) As many people have suggested, the generator acts as a motor if more electricity comes in than goes out, and that turbines are often seen turning with only a slight breeze. It has been suggested that it looks better to have them turning ...

Also in the same section: "Nacelles and towers should be kept clear of leakage from internal fluids." That suggests, of course, that leaks are common.

More (section 6.15): "Decommissioning should involve the removal of all of the aboveground elements of the wind energy development and making good of the site, with the possible exception of roads and tracks where some further use can be found for them and this is approved by the planning authority. Foundation pads can be covered with local soil and left for natural re-vegetation, although they should be re-sodded in highly exposed locations." A reminder that "restoration" of the site means leaving several tons of cement and steel right below the surface. That is the usual provision in the U.S. as well.
