Turbines Linked to Vibro-acoustic Disease

Industrial wind turbines, infrasound and vibro-acoustic disease (VAD)

Documented in a press release dated May 31, 2007 from the Vibro-Acoustic Disease (VAD) research group in Portugal, people living in the shadow of industrial wind turbines have moved a step closer to understanding the nature of the Wind Turbine Syndrome many of them experience and complain about. Professor Mariana Alves-Pereira (an acoustical engineer) and Dr. Nuno Castelo Branco (a surgical pathologist) recently took numerous noise/vibration measurements within a Portuguese home surrounded by four (4) industrial wind turbines. The closest turbine is nearly 1000 feet (300 meters), from the affected home. The turbines have been operating since November 2006. The scientific report on this research will be formally presented at Internoise 2007, to be held on 28-31 August in Istanbul, Turkey.

These results scientifically demonstrate that windmills in the proximity of residential areas produce acoustical environments that can lead to the development of vibroacoustic disease (VAD) in the nearby home-dwellers.

Gamesa to Host Shade Township Public Meeting

Town hall meeting to be held

Wind energy company Gamesa Energy USA will be hosting a town hall meeting in order to discuss local projects and the industry in general, representatives announced.

The public forum will be held on from 7 to 8:30 p.m. June 12 at the Shade High School gymnasium, in Cairnbrook, company spokesman Neil Simpkins said.

Gamesa officials will be on hand to provide information about wind energy, construction plans and renewable energy in general, he said.
They will also address public concerns about specific projects like the Shaffer Mountain Wind Farm, he said.

The 30-turbine wind farm, which is projected to extend through parts of Shade and Ogle townships in Somerset County and Napier Township in Bedford County has generated much media coverage in the last six months as several local organizations have been working to block it.

Shaffer Mountain Petition Online

Altoona Mirror, May 27, 2007, by Allison Bourg, abourg@altoonamirror.com

NEW PARIS — Concern over a proposed wind plant on the border of Bedford and Somerset counties is growing, with an online petition asking residents to speak out against the plans.

About 100 residents have signed the petition at www.shaffermountain.com, which was started by several citizens’ groups in both counties. The groups oppose Gamesa Energy USA’s tentative plans to build wind turbines atop Shaffer Mountain.

Gamesa officials said last week they plan to hold a town hall-style meeting in June in Somerset County to address residents’ worries. A date has not been set.

Important 1st Step

The Energy Policy Reform and Revitalization Act of 2007 (see H.R. 2337), now before the House Committee on Natural Resources, includes a provision on wind energy that represents an important first step in enforcing necessary protections for the natural environment impacted by industrial wind energy development.

This provision will put into law what the wind industry and its proponents already profess to support, i.e. the proper siting of facilities in order to “avoid impacts, including cumulative impacts, on birds, bats, and other wildlife to the greatest extent practicable based on data gathered during preconstruction surveys”.

Informed public scrutiny: Supporters of wind turbines need a reality check

By Arthur Hooton, The Charleston Gazette, wvgazette.com, 16 May 2007

Excerpt:
Advocates of industrial wind seem to fall into two camps: the dreamers and the schemers. The dreamers are engineers who think they can invent their way out of the inherent flaws of industrial wind by trying to make the turbines ever larger and more efficient, while hoping an industrial-scale electricity storage system will eventually present itself. They’ve had this same dream for over 30 years now. The schemers know it’s not going to happen, but they’re quite willing to lobby for legislation that guarantees a payoff to anyone with money to invest.

Imagine if Congress enacted a law requiring 20 percent of all goods coming into the United States be transported on cargo sailing ships to cut pollution caused by marine diesel engines. The dreamers would build massive, carbon-fiber-hulled ships equipped with titanium masts and Kevlar sails; and the schemers would make sure that investors got tax breaks, credits and subsidies for each ton of cargo hauled. When the wind didn’t blow, diesel powered, ocean-going tugboats would be dispatched to pull becalmed vessels into port with no net change in pollution and with major disruptions in product deliveries. Because the cargo sailing ships didn’t have engines on board, owners would still get tax credits, and consumers could blissfully believe that their goods were being delivered by clean and green energy. That’s the real story behind Big Wind. It’s called consumer fraud and the state of West Virginia does not have to be a party to that fraud.

Penelec, Gamesa vote near; Wind farms would be linked to electric transmission grid

HT: News Watch

The keepers of the regional power supply may vote next month on Penelec proposals to link area wind farms into the electric transmission grid.
About $13 million in projects are planned, mostly in Blair, Cambria and Somerset counties, as wind farms associated with Gamesa Energy USA sprout up.

A committee of PJM Interconnection received an update last week on the utility’s projects in Blair, Cambria and Somerset counties.

Utility companies make proposals to PJM, which conducts feasibility studies to estimate interconnection costs and construction time. The Transportation Expansion Advisory Committee must authorize new connections to the power grid before the PJM board gives its approval.

The PJM board is set to meet June 21.…

PJM oversees the power grid serving 51 million people in Pennsylvania, 12 other states and the District of Columbia….

90% Useless and Wasted

90% OF RATED WIND TURBINE CAPACITY IS USELESS

What if the electricity from a wind farm is generated mainly when there’s no economic use for it? It can’t be stored, so it is simply wasted.

As the California experience documents below, wind generation and grid load have different patterns.

A similar condition prevails in upstate New York, as admitted by General Electric. (See GE’s System Performance Evaluation to the NY State Energy Research and Development Authority.) Likewise in our area. The result is that even though a turbine or wind farm is usually touted for its rated capacity, only about 10% of that represents electricity that is usable.

That’s right. Not the 1.5 MW - 2.0 MW turbine capacity touted by wind brokers and pro-wind media. Not even 20-30% of that amount, which results after factoring in the lack of optimal wind (efficiency factor) prevalent in our area. But only about 10%, or 0.15 MW, will be expected to be usable from a 1.5 MW turbine, because the electricity it generates will be generated mostly at night and other times of least economic use for it, when electricity demand on the grid is lowest.

When you read that a wind farm of 40 turbines, each rated at 1.5 MW, will generate 60 MW of electricity, you should understand how misleading these numbers actually are, when it comes down to electricity that is actually usable. In our area, dividing by ten wil give more realistic estimates.

By using rated capacity as the basis for usuable generation estimates, wind brokers exaggerate by a factor of 10 or more.

Wind farms may not lower air pollution, study suggests

Wind power could also reduce coal-plant carbon dioxide, which is thought to cause climate change, but the impact may be small, the report said. By 2025, wind turbines could cut carbon dioxide output by 4.5 percent compared with what it would otherwise have been, but this "would only slow the increase," said Dr. Risser. "It wouldn't result in a decrease in the amount of CO2."

National Academies Report

Environmental Impacts of Wind Projects,
National Academies Report
Released May 3, 2007

The National Research Council has released a report this morning on the environmental impact of wind turbines. The report is currently available at http://www.eswr.com/latest/307/nrcwind.htm ; you have to download the report in sections. Below is a summary of "key points" about this NRC research publication, which was prepared by Rick Webb - a co-author of the report.

National Academies Report
ENVIRONMENTAL EFFECTS OF WIND PROJECTS
- some key points from the report concerning benefits and risk, Rick Webb, 050307

Contribution to Electricity Supply and Emissions Reductions

Based on 3 DOE projections for U.S. onshore wind development by 2020:
· 19 - 72 GW installed capacity; or 9500-36000 2-MW turbines.
· 2 - 7 % of installed generation capacity.
· 1.2 - 4.5% of actual generation (less than installed capacity due to intermittency of wind).
· 3.5 - 19% of the projected increase in total generation from all sources (that is, 96.5 - 81% of new generation must be obtained from other sources).
· No reduction in NOx and SO2 emissions – pollutants regulated by emissions caps.
· 1.2 - 4.5% reduction in CO2 emissions from electrical generating units, which at present only account for 39% of total U.S. CO2 emissions from energy use.

· Given that the density of the wind resource is less for the Mid-Atlantic region than for the U.S. as a whole, the benefits in terms of electricity supply and emissions reductions will be proportionately less for the Mid-Atlantic region than for the country as a whole. [Boldface added]

Cumulative Impact on Birds and Bats

Based on two projections for wind development in the Mid-Atlantic Highlands and the range of mortality observed at existing Appalachian wind projects:
· National Renewable Energy Laboratory projection for wind development: 2,158 MW of installed capacity or 1439 1.5-MW turbines.
o 5,805 to 25,183 birds killed per year
o 33,017 to 61,935 bats killed per year
· Projection for wind development based on the PJM Interconnection Queue: 3.9 GW installed capacity or 2571 1.5 MW turbines.
o 10,372 to 44,999 birds killed per year
o 58,997 to 110,665 bats killed per year
· There is insufficient information to assess the potential for population impacts on birds in the eastern U.S.
· The potential for impacts on bat populations in the eastern U.S. is significant.

Rick Webb note: The committee was not charged with making a determination about the significance of the potential contribution of wind energy development. My personal perspective, however, is that wind energy development on Appalachian ridges carries great risk of environmental harm and very little potential for benefits.
