Solar energy is Pennsylvania's cleanest, cheapest and fastest energy resource. It also creates more jobs than any other form of energy. To provide affordable, clean electricity it is essential that Pennsylvania accelerate solar statewide.  These maps, graphs and charts provide a snapshot of how much solar energy is being used in PA and how we compare with surrounding states.  Data sources include the PA Public Utility Commission and the Solar Energy Industries Association.  Special thanks to a group of Bryn Mawr and Haverford students for their help in pulling these together.
