The 2.0 million kW of electricity produced by the power plants accounts for only about 50% of the available energy of the moving water of the Niagara river. What accounts for the "lost" energy? Energy of the water is not lost; it is turned into other forms of energy in the system. O Energy is turned into air, adding fluid to the system but not energy. O Energy is turned into water, adding mass to the system but not energy.
