Economics and quality issues

In a July 9, 2007 Wall Street Journal article ( http://www.windaction.org/news/10617 ), wind power was described as "basically a cottage industry, until recently", and the race to build wind facilities worldwide has created a turbine shortage. Manufacturing of the turbines, and their 8000 specialty parts, is being squeezed, raising prices and the potential for quality problems. Current reports from Germany ( http://www.windaction.org/news/11519 ) detail quality problems with installed turbines, "...wind power providers and experts are now concerned. The facilities may not be as reliable and durable as producers claim... Fractures form along the rotors, or even in the foundation after only limited operation". Last week, a Siemens wind turbine at PPM's Kondike III site in Oregon collapsed killing one person and seriously injuring a second ( http://www.windaction.org/news/11547 ).

Eco-dream versus reality

Energy policymakers in Massachusetts, Delaware, and elsewhere see a future where 1000’s of giant wind turbines, blades reaching to 300-feet in length, will populate the deep waters off the U.S. coast from Maine to Cape Hatteras (NC) and beyond. They envision wind energy as the primary source of electricity for eastern population centers. The fickle nature of wind will be 'corrected' by building new onshore gas plants that generate during low wind conditions. Little has been voiced publicly about this eco-dream. Is it even possible using existing infrastructure? or will a new super-grid need to be created? How much of the enormous cost will be borne by the public? While money is being expended today, have there been policy and technical discussions reviewing the feasibility? There is very limited experience worldwide for deep-water wind development and none in the U.S. It's worth noting that the near-shore Cape Wind (MA) and LIPA (NY) projects, both heavily reliant on public subsidies and existing infrastructure, will each cost nearly a billion dollars to build. The one Texas offshore proposal, with subsidies, has been deemed economically unviable and scrapped by the developer.

Migratory birds and bats

New York's Maple Ridge wind energy facility (195 turbines) will slaughter up to 10,000 migratory birds and bats annually. The collision rate reported after the first fall season mortality survey were 34.12 targets per turbine or 6700 collisions, 72% of which are migrating bats (see: http://www.windaction.org/documents/8533 ). IWA estimates yearly collisions to rise to 10,000 after accounting for spring migration and other year-round migrants. Reports that cite the number of carcasses recovered are not representative of the number of birds and bats actually killed.
