Photovoltaic systems are rampantly being installed across the U.S.
Chicago became the epicenter for LEED-certified buildings more than a decade ago with the opening of the Chicago Center for Green Technology and now has the most LEED-certified projects in the U.S .
Photovoltaic systems are the most popular installation among homeowners, and California stands as the top state for solar energy. The Convention Center houses one of the largest public-facility solar installations on the West Coast, generating 1 million kilowatt-hours of pollution-free electricity.
The top 9 states for Solar power are:
7. New York
8. New Jersey
