In 2010, the BP Oil Spill killed a little over 7,000 birds.

Each year, wind turbines kill 500,000.

“I estimated 888,000 bat and 573,000 bird fatalities/year (including 83,000 raptor fatalities) at 51,630 megawatt (MW) of installed wind-energy capacity in the United States in 2012,” writes K. Shawn Smallwood, author of the study that was published in the Wildlife Society Bulletin.
