Independence National Historical Park

Independence National Historical Park, the home of Independence Hall and the Liberty Bell in Philadelphia, tells the story of ideas that have shaped our nation. In 2015, the park replaced six of its conventional mowers with propane mowers, as well as three of its conventional refuse-collection vehicles with those that run on electricity. Over the course of the next 10 years, the park expects to save nearly $20,000, all while demonstrating how these technologies are helping to protect one of America's most important historic sites.
