THE MARVEL OF WATER ENERGY. Using the movement of water to generate power for machinery and other applications was discovered thousands of years, dating back to ancient Greece, and has remained a reliable means of producing energy through civilization. In ancient Greece, the Greeks created large wheels waving in the water and power bars connected to the machines used to grind wheat and flour.
By 1700, developing countries around the world were doing most of the water power for its energy needs. Various ways to use natural rainfall to produce energy is introduced through the years. The most common process uses water to activate a motor that is connected to an independent generator that produces energy that can be used for a variety of applications.
