Federal Correction Institution in Fairton, N.J.
This New Jersey prison boasts a solar power system made up of more than 1,800 solar panels. The system’s 402-kilowatt solar potential, according to reports, should reduce the facility’s fossil fuel consumption by 27 percent and reduce its carbon emissions by 790,000 pounds per year. The energy savings will be used over the next several years to repay construction costs of the system. Once that's paid off, New Jersey will reap the financial rewards of going green. (There was also a green jobs benefit to this installation: Prisoners learned about green technology when they helped install the system.)
