The waterfalls have lots of water but the water is spread out and is not of the speed and pressure as required by the turbine plates. Also the water from the waterfalls cannot be controlled as easily as in the case of dams. At times of emergencies, the waterfall is highly unreliable. read more
Humans have long been harnessing the power of naturally flowing water in order to make life more convenient. Before the invention of electricity, river waterfalls were used to move turbines, which powered mills that could grind wheat into flour far faster than any human hand. read more
Energy from natural sources like river, wind and sun could easily be harnessed to generate electricity and the technology for doing so, is available today. In the case of river, water turbines could be utilized by individuals than expecting the Govt. to use them on a large scale. read more
Before the invention of electricity, river waterfalls were used to move turbines, which powered mills that could grind wheat into flour far faster than any human hand. Not only were these machines so effective that they are still used today, but they became the mechanical basis for generators which could create electricity from the motion of falling water, or hydroelectricity. read more
Hydroelectric Energy and the Environment Hydroelectricity relies on water, which is a clean, renewable energy source. A renewable source of energy is one that will not run out. read more
