Pennsylvania has 892 megawatts of conventional hydropower and 1,583 megawatts of pumped storage hydropower capacity and hundreds of people employed in the traditional hydro-electric field. The U.S. Department of Energy reports that hydroelectric power is the largest source of renewable electricity in the United States, producing about 6.3% of the nation's total electricity throughout the last decade.
Hydropower is a clean energy resource, can generate power quickly for emergency back-up, provide flood control, irrigation and water supply.
How Does Hydroelectric Power Work?
Hydroelectric power is the transformation of the kinetic energy of water, a function of mass and velocity of water flow. Hydroelectric power is created when the kinetic energy of flowing water is channeled by a dam into a turbine that spins a generator to convert the energy into electricity.
