More than 600,000 bats may have been killed at wind farms in the continental US last year. That’s trouble for agriculture: the US Geological Survey estimated in 2011 that the bats’ natural pest-control saves the industry at least $3 billion a year.
Wind can be a very significant power provider in the United States, especially in the Midwest. Environmental lawyer and writer Philip Warburg talks about wind as a resource, including how it relates to the economy and climate change. He spoke at Seattle's Town Hall on December 4, 2012. The talk was introduced by Denis Hayes, CEO of the Bullitt Foundation and coordinator of the first Earth Day.
