Bird kills

Years ago, when I was working as a policy analyst for the Snohomish County Public Utility District (PUD), the region confronted a question: Should owners of the Centralia Coal Plant, including the PUD, sell their shares? The answer depended on a host of issues, including economics, the environment, alternative strategies, etc. I researched and analyzed, eventually producing a report, which I have evidently misplaced. In the end, the several utility owners, including the PUD, decided in the affirmative. 

One of the issues I investigated for the report was bird kills. At the time, there were many groups opposing the construction and operation of windmills on the grounds that they killed birds. In my research I discovered that far more birds die from Centralia plant emissions than are killed each year by wind turbines. 

Recently, there were reports that concentrated solar arrays in California were frying birds that strayed near them. Estimates ran as high as 28,000 killings per year. U.S. News looked at data on various resources and their impacts on birds. Here is a chart that I produced based on that data:

Yet another reason to leave coal in the ground.
