Bird fatality study at Altamont Pass Wind Resource Area (APWRA)
January 25, 2008
by Altamont Pass Avian Monitoring Team:
The current management goal for the Altamont Pass Wind Resource Area (APWRA) is to significantly and substantially reduce the fatalities of birds resulting from collisions with the wind turbines and other turbine-related incidents. This is the first report on bird/bat mortality rates at the APWRA since the management plan was implemented. "The results of this study show an apparent continued trend of high bird fatalities, both raptors and non-raptors at APWRA. The number of annual fatalities does not appear to be decreasing despite implementation of specific conservations measures including the cross-over winter shutdown program, high risk turbine removal and blade-painting."
Boulevard Planning Group protest letter to Bureau of Land Management
January 3, 2008
by Donna Tisdale
The Boulevard Planning Group submitted this protest letter to the Bureau of Land Management in response to the Bureau's proposal to open 6,900 acres of public lands within the McCain Valley area for wind energy development.
Comments submitted to Santa Barbara County Energy Division, California, by the Environmental Defense Center (EDC) regarding the draft environmental impact report (DEIR) for the Lompac Wind Energy Project.
California ISO integration of renewable resources report (Draft)
August, 2007
by CA-ISO, GE Energy Consulting, Pacific Northwest National Laboratory, AWS Truewind
This report details transmission and operating issues and recommendations for integrating renewable resources on the CAISO Control Grid. The CAISO discusses the gross variations in electric production from wind energy due to the intermittent nature of the resource. During periods of highest demand, the winds drop off.

The Overlooked Environmental Cost of a Wind Generation Portfolio to Serve the Need for Power
June, 2007
by Lincoln Wolverton and Raymond Bliven
The November passage of Initiative 937 adds Washington to the states with renewable portfolio standards. Wind-powered generation is a resource of choice in meeting renewable standards, and it has been highly touted for its environmental benefits. Considered in isolation, the environmental benefits of a wind resource are undoubtedly warranted. However, it is misleading to consider wind on an isolated basis—that is, outside of the context of the full power-supply portfolio that is necessary to serve load. In the context of an integrated portfolio, much of the environmental benefit disappears and may even be non-existent as compared with other resource portfolio choices. In particular, a full assessment of the impact of wind resources on the environment necessitates a look at the energy consequences of adding wind-generation to an integrated portfolio in the context of meeting load. Accounting for energy, it is likely that there is no significant environmental difference between a resource portfolio adding wind generation and one adding high-efficiency combined-cycle gas turbines. It is also likely that the wind-based portfolio results in little reduction, if any, in the need for fossil fuels and therefore little reduction in the exposure to their price swings and environmental consequences. That is, the emissions and fossil-fuel impacts of a wind-based portfolio appear little better than a non-wind-based portfolio.
Editor's Note: This paper makes a critically important point re. wind's purported environmental benefits, i.e. "...it is misleading to consider wind on an isolated basis—that is, outside of the context of the full power-supply portfolio that is necessary to serve load. In the context of an integrated portfolio, much of the environmental benefit disappears and may even be non-existent as compared with other resource portfolio choices." In short, wind's environmental benefits (if any) will be grid-specific depending on the emissions generated (if any) of the reliable generating source(s) required to back it up.
