On Monday March 23rd at 5:00 pm and Thursday, March 26th at 10:00 am, the Princeton Public Library's Environmental Film Festival will be showing Switch. This 2012 documentary explores the question of how we will transition from traditional energy sources such as coal and oil to renewable sources. The Washington Post calls it "Smart and refreshingly free of hot air." The film is part of a project that seeks to educate about energy conservation and efficiency. In anticipation of the film's showing, Sustainable Princeton will share an energy efficiency tip each day from the project. Check our Facebook page & Twitter @sustainptn to get your energy efficiency tip of the day and be sure to come see the film at the Festival.
