One thing important to us is hydroelectric power. Hydroelectric power is power derived from the fall of water from a higher to a lower level, and extracted by means of waterwheels or hydraulic turbines. Waterpower is a natural resource, available wherever a sufficient volume of steady water flow exists. Did you know that in 1920, 40% of all the power used was made by hydroelectric plants? But something pitifull happened. The amount dropped to 10% in 1990. But, in the early 1990s, the U.S. was second to Canada in total production of hydroelectric power who gets about 62 percent of its electricity from hydroelectric sources. Worldwide, hydropower represents approximately a quarter of the total energy generated and is growing in importance; in many countries, it is the dominant source of electric power. The leaders are Norway which is 99 percent, Zaire now 97 percent, and Brazil who has 96 percent.
