Geotourism Travelers' Tips:
1. What is geotourism?
The formal definition is, "Tourism that sustains or enhances the geographical character of the place being visited -- its environment, culture, aesthetics, heritage, and the well-being of its residents." In other words, travel for people who like distinctive places and care about protecting them.
2. Who are geotravelers?
... they support local businesses and travel organizations that care about conservation, preservation, beautification, and benefits to local people.
3. How can I be a good geotraveler in the Northeast Kingdom?
The Kingdom got its name from its natural beauty. Residents are determined to retain that beauty. ...
9. What should I do, and not do, if I want to buy property or build a home in the Kingdom?
The Geotourism Alliance is committed to preserving sense of place in the Kingdom. If you decide to purchase a home or move to the area, please consider local values and the effect you and your house have on the landscape, culture, environment, and communities. ...

NO industrial wind turbines in National Forest
Dear Bob Bayer, Project Coordinator, USDA Forest Service --
Please do not allow the construction of industrial wind turbines on National Forest lands in Readsboro, Vt., as proposed by PPM Energy.
Such construction would be a permanent loss of the land for any other purpose. It would require acres of clearing for each turbine, new heavy-duty roads, and excavation (including blasting) for steel-reinforced concrete bases that would remain in the ground forever.
The motion and consequent noise and vibration of the giant turbines are a threat to flying animals -- birds, bats, and insects -- and would disturb the lives of animals on and in the ground.
Their height and required safety lighting would adversely transform the character of a rare natural landscape.
These and other impacts far outweigh the potential benefit of the facility as a source of nonpolluting renewable energy.
As you know, wind energy is highly variable, intermittent, and nondispatchable. Thus, integrating it into the grid is problematic.
Other sources must be kept available to balance the infeed from wind. They may continue to burn fuel in standby mode, burn fuel at lower efficiency in a ramped down state, or burn extra fuel in more frequent starts.
The beneficial effect of wind as a clean source of energy is therefore substantially diminished as a supplier to the grid.
In many cases, the infeed from wind may simply be absorbed as a tolerable variation in line voltage, thus not displacing any other source at all.
In sum, forest land and habitat should not be sacrificed for such a negligible potential benefit that will not measurably alter our energy use.
Reject the proposal of siting wind turbines in the National Forest.
The forest is not renewable.

Protected wolves and hyenas disappearing in Indian district
From newindpress.com, via National Wind Watch:
Three years ago, Gajendragad [in Gadag district] was recognised as a safe haven for highly endangered species like the Indian grey wolf and striped hyenas, but then came wind farming and wind mills with huge noisy fans and human traffic to maintain these machines. It drove away these species from their habitat.
Dr H N Kumara, wildlife biologist, observed the changes during his visits to the place. ‘‘Some years ago, I could sight huge packs of animals during my visits. My week-long stay here had revealed that these places were an ideal den for the wolves. But after a couple of years, the habitats were destroyed and wolves disappeared,’’ he explained.
The hills were destroyed for the construction of roads and huge mills by a private firm, replacing the dry decidous place. The only beneficiary is cattle, for they can graze free and without fear. ‘‘There were a lot of wolves here. And the sight of grazing sheep was rare. Now the situation is the reverse. The wolves have gone,’’ said Goni Basappa Koralahalli, a shepherd.
[Poachers also take advantage of the new roads. --Ed.]
Prashant Rathod says he had sighted wolves several times, but it was more than a year ago. Now no one comes across wolves. The status of the Indian striped hyena, an endangered species, is no different. They have disappeared since the past three years.
‘‘This is a significant habitat for these hyenas and we had seen some near goshalas around Kalakaleshwar temple. But they are gone. It is possible that too much human interference might have driven them away,’’ he said.
Power generation is permitted on this government land and about five megawatts of power is generated. Officials from the forest department were not available for comment on the alarming migration of animals. The forest department had reported many incidents where bears made life miserable for people in Arasikere and parts of Hiryur recently.
The Indian grey wolf (Canis lupus) is found in the Deccan plateau and differs from its Himalyan cousin. Though considered secondary predators with significant roles in the food chain, the numbers of this nocturnal and diurnal species is dwindling rapidly due to poaching, loss of habitat and threat from feline species.
The species is protected under Wildlife Act Schedule 1.
The Indian striped hyena, a scavenger species was sighted in places like Gajendragad, Chitradurga, parts of Tumkur region, around Doroji, Sandur and Bidar.

Corrosion grounding off-shore wind
From Environmental Data Services (U.K.), via Friends of the Irish Environment, comes a report of a Sept. 20 article in the Norwegian engineering journal Teknisk Ukeblad about off-shore wind energy facilities being shut down because of corrosion damage to gearboxes, rotor blades, and other mechanical components. Affected sites include Nysted and Horns Rev off the Danish coast, Barrow in the Irish sea, and Kentish Flats in the Thames estuary. Vestas has suspended sales of its 3-MW off-shore turbine.
The Swedish engineering journal Ny Teknik also carried an article on the subject on Sept. 19, confirming Vestas' problems and noting that the technology still needs a lot of work (how much more money will we throw down this dead end?) to withstand the harsh environment off shore.

Wind turbines and noise
From abstracts of papers presented at the Wind Turbine Noise 2007 conference, Sept. 20-21, Lyon, France:
"In wind turbines the drive train, especially the gear box, is a significant source of noise. Significant contributions come from the gear mesh and from resonances of the structure like the main frame or the torque arm. The structure-borne noise from these sources is transferred either to the rotor or to the tower and radiated to the environment. The contributions to the noise spectrum from these sources are single tones in the frequency range from about 100 Hz to about 600 Hz."
"The larger proportion of the general population who live far from them think wind turbines are great -- while the smaller proportion representing people with homes near where wind turbines were subsequently erected have concerns, particularly about noise. On a popular vote basis, as seen by elected officials, the choice is clear, but on a justice basis, who looks out for the impacted few? ...
"The results for one wind farm, the Kingsbridge wind farm near Goderich Ontario, which has the closest distance between the wind turbines and the Environment Canada weather office monitoring station, show that about 31% of the hours of the year show an unmasked noise output above the Ontario Standard, and for nearly 10% of the hours of the year, the noise is significantly above the provincial standard (over 3 dBA), in many cases about 10 dBA above the background level produced by the wind at the receptor. In the 6 months from October 2006 to March 2007, on 64% of the days, there were hours of unmasked noise. This demonstrated the problem to be chronic and significant in nature. For another Ontario wind farm, the results in the summer period between May 1st and August 31st, 2006 showed 59% of the days demonstrated the problem, with it occurring 48% of the nights, and 33% of the nights showing the condition sustained for 3 or more hours. ...
"The presentation will go through the results in detail. They will show that the current Ontario interpretation by the Ministry of the Environment is not adequate to protect the public from excessive annoyance."
"Previous studies have shown that wind turbine noise could be annoying at sound pressure levels lower than those known to be annoying for other community noise sources, such as road traffic. This could be due to the special characteristics of wind turbine noise (amplitude modulation) that make the sound easily perceptible. It could furthermore be due to atmospheric situations influencing large modern wind turbines more than older ones, leading to higher sound exposure than accounted for in the planning process."
