The state park system across the U.S. is critical to historic preservation, natural history, wildlife conservation, and education. The Energy Department plays an important role in supporting state parks thought clean energy investment. Last year, the Nevada Governor’s Office of Energy used funds from the Energy Department’s State Energy Program to expand the use of solar power at three off-grid state parks: Berlin-Ichthyosaur State Park, Elgin School House State Historic Site, and Beaver Dam State Park.
