Research Report Released on Improving Methods for Estimating Fatality of Birds and Bats at Wind Energy Facilities
A study released in February by CalWEA found that equations commonly used to estimate total bird and bat fatalities from sampling performed at wind energy facilities can produce widely varying results using the same input data. The equations’ results were found to differ by up to a factor of four, with some equations tending to have a negative bias while others showing a consistently positive bias, both carrying the potential to generate results that differ significantly from actual mortality. The study developed a new equation that, paired with new field sampling protocols, is able to produce unbiased results. Slides from a webinar presentation made on September 26, 2012 are available here. A link to the webinar recording is available here. Download the Report.

Fast Facts about California Wind Energy
+ As a result of strong public policy, California was the first U.S. state in which large wind energy projects were developed, beginning in the early 1980's.
+ Wind energy projects totaling approximately 5,549 megawatts (MW) of capacity are operating in California today, providing enough electricity to power more than 2 million California households. This represents more than a tripling of wind energy capacity since California's RPS law was adopted in 2002.
+ Wind energy projects comprised 75% of the renewable energy development that has occurred under California's 2002 Renewables Portfolio Standard (RPS) law, as of August 2012.
