Nothing wrong with ocean based wind farms.

The biggest problem is no means of storing the energy has been developed. If there is a miscalculation in how the energy is metered it can cause the power grid to be blown.

Lightning capture would be the most productive form of energy. Its a matter of developing a containment field.

Q, wind generated electricity is big in the central valley in Ca.
" The older wind generators are being phazed out as they are now Considered largely obsolete, these numerous small turbines are being gradually replaced with much larger and more cost-effective units. The small turbines are dangerous to various raptors that hunt California Ground Squirrels in the area. 1300 raptors are killed annually, among them 70 golden eagles, which are federally protected; in total, 4700 birds are killed annually.[2] The larger units turn more slowly and, being elevated higher, are claimed by the manufacturers and wind farm proponents to be less hazardous to the local wildlife. This claim is supported by a report done for the Bonneville Power Administration[3]. Currently the Altamont wind farm is shut down by government order for several months of the year to attempt to mitigate bird mortality."
Kind of eerie driving over the Altamont Pass at night and hearing that strange humming sound....

Kinda like driving East on the I 10 to Palm Springs.

Now that Kennedy is gone, there will be wind farms in the Atlantic East of Cape Cod.

Green Light For 130 Wind Turbines Off Cape Cod

Well Ken Salazar has spoken and it looks like Cape Cod will receive its wind farm according to the NY Times. Views still appear polarized and emotions will continue to run high as those for the project including both Greenpeace and the US Chamber of Commerce extol its virtues of low carbon and reduction in imported energy supplies while those against it led by the Kennedy family -appear to largely boil down to NIMBY (not in my back yard).

And that is exactly why we will never have any new energy sources in the US. Not in my back yard.
Its all well and fine until it comes to your backyard.

Or if it kills a fish ... or a weasel ... or a bird ... or might actually have a chance at working.

Back in Wisconsin

My home state of Wisconsin is a good example of current research. In December of 2002, the report "Effects of Wind Turbines on Birds and Bats in Northeast Wisconsin" was released. The study was completed by Robert Howe and Amy Wolf of the University of Wisconsin-Green Bay, and William Evans. Their study covered a two-year period between 1999 and 2001, in the area surrounding the 31 turbines operating in Kewaunee County by Madison Gas & Electric (MG&E) and Wisconsin Public Service (WPS) Corporation.

The report found that over the study period, 25 bird carcasses were found at the sites. The report states that "the resulting mortality rate of 1.29 birds/tower/year is close to the nationwide estimate of 2.19 birds/tower.16- The report further states, "While bird collisions do occur (with commercial wind turbines) the impacts on global populations appear to be relatively minor, especially in comparison with other human-related causes of mortality such as communications towers, collisions with buildings, and vehicles collisions. This is especially true for small scale facilities like the MG&E and WPS wind farms in Kewaunee County."17

The report goes on to say, "previous studies suggest that the frequency of avian collisions with wind turbines is low, and the impact of wind power on bird populations today is negligible. Our study provides little evidence to refute this claim."18

So, while wind farms are responsible for the deaths of some birds, when put into the perspective of other causes of avian mortality, the impact is quite low. In other words, bird mortality at wind farms, compared to other human-related causes of bird mortality, is biologically and statistically insignificant. There is no evidence that birds are routinely being battered out of the air by rotating wind turbine blades as postulated by some in the popular press.

Utility transmission and distribution lines, the backbone of our electrical power system, are responsible for 130 to 174 million bird deaths a year in the U.S.1 Many of the affected birds are those with large wingspans, including raptors and waterfowl. While attempting to land on power lines and poles, birds are sometimes electrocuted when their wings span between two hot wires. Many other birds are killed as their flight paths intersect the power lines strung between poles and towers. One report states that: "for some types of birds, power line collisions appear to be a significant source of mortality."2

Collisions with automobiles and trucks result in the deaths of between 60 and 80 million birds annually in the U.S.3 As more vehicles share the roadway, and our automotive society becomes more pervasive, these numbers will only increase. Our dependence on oil has taken its toll on birds too. Even the relatively high incidence of bird kills at Altamont Pass (about 92 per year) pales in comparison to the number of birds killed from the Exxon Valdez oil spill in Alaska. In fact, according to author Paul Gipe, the Altamont Pass wind farm would have to operate for 500 to 1000 years to "achieve" the same mortality level as the Exxon Valdez event in 1989.

Tall building and residential house windows also claim their share of birds. Some of the five million tall buildings in U.S. cities have been documented as being a chronic mortality problem for migrating birds. There are more than 100 million houses in the U.S. House windows are more of a problem for birds in rural areas than in cities or towns. While there are no required ongoing studies of bird mortality due to buildings or house windows, the best estimates put the toll due collisions with these structures at between 100 million and a staggering 1 billion deaths annually.4

Lighted communication towers turn out to be one of the more serious problems for birds, especially for migratory species that fly at night. One study began its conclusion with, "It is apparent from the analysis of the data that significant numbers of birds are dying in collisions with communications towers, their guy wires, and related structures."5 Another report states, "The main environmental problem we are watching out for with telecommunication towers are the deaths of birds and bats."6

This is not news, as bird collisions with lighted television and radio towers have been documented for over 50 years. Some towers are responsible for very high episodic fatalities. One television transmitter tower in Eau Claire, WI, was responsible for the deaths of over 1,000 birds on each of 24 consecutive nights. A "record 30,000 birds were estimated killed on one night" at this same tower.7 In Kansas, 10,000 birds were killed in one night by a telecommunications tower.8 Numerous large bird kills, while not as dramatic as the examples cited above, continue to occur across the country at telecommunication tower sites.

The number of telecommunication towers in the U.S. currently exceeds 77,000, and this number could easily double by 2010. The rush to construction is being driven mainly by our use of cell phones, and to a lesser extent by the impending switch to digital television and radio. Current mortality estimates due to telecommunication towers are 40 to 50 million birds per year.9 The proliferation of these towers in the near future will only exacerbate this situation.

Agricultural pesticides are "conservatively estimated" to directly kill 67 million birds per year.10 These numbers do not account for avian mortality associated with other pesticide applications, such as on golf courses. Nor do they take into consideration secondary losses due to pesticide use as these toxic chemicals travel up the food chain. This includes poisoning due to birds ingesting sprayed insects, the intended target of the pesticides.

Cats, both feral and housecats, also take their toll on birds. A Wisconsin Department of Natural Resources (DNR) report states that, "recent research suggests that rural free-ranging domestic cats in Wisconsin may be killing between 8 and 217 million birds each year. The most reasonable estimates indicate that 39 million birds are killed in the state each year."11

There are other studies on the impacts of jet engines, smoke stacks, bridges, and any number of other human structures and activities that threaten birds on a daily basis. Together, human infrastructure and industrial activities are responsible for one to four million bird deaths per day!

I still say that they should put a screen over the blades like my room fan.

05-05-2010, 04:32 PM
Better still. They are developing new safer blades. They hav dunn crash tests with blades uzing crash eagle dummys in a wind tunnel. I must say that the white plastik eagle dummys look funny, what with being covered in black and white stripes and checkers. Anyhow, the next generation of blades will hav air bags that employ on impakt.

Well its a good thing that birds are such prolific egg layers with everything stacked against them the way it is.
