In a world where “going green” is the cool thing to do, harnessing the power of water in the form of hydroelectricity is the largest source of clean, renewable energy in the United States today. According to hydro.org, “hydropower accounts for 52 percent of the nation’s renewable electricity generation and 7 percent of total electricity generation”, potentially leaving millions in the dark if a reliable and consistent flow of water is not realized. The various types of hydropower plants in use today each have their own unique uses for geomembranes to assist with the conservation and delivery of water within their systems, helping to provide green energy more efficiently for the masses.
