Top 30 Local Government icon.The Top 30 Local Government list represents the largest green power users among local government partners within the Green Power Partnership. The combined green power use of these organizations amounts to nearly 2.9 billion kilowatt-hours annually, which is equivalent to avoiding the carbon dioxide emissions from the electricity use of more than 273,000 average American homes annually.

My Administration has made a commitment to generate 20% of electricity used in Philadelphia from alternative energy sources, as laid out in our sustainability plan Greenworks Philadelphia. We are honored to be [recognized for] our efforts and will continue to pursue clean energy policies that benefit residents and the environment.
- Mayor Michael A. Nutter, City of Philadelphia
