Click here to know more about the interesting facts on Hydro electric energy. You may have questions like what is hydro electric energy. And how electric energy is generated by hydro power. To know the answers click here
Hydroelectric energy is simply electricity produced from hydropower. Hydropower is concerned with converting falling water into electric energy. A dam is built to raise the water level of rivers and so falling water is created. A dam also allows us to control the flow of water and the reservoir contains stored water.
A turbine is propelled by the force of the falling water causing its blades to spin.
A generator is connected to the turbines which spins as the turbine spins and produces electrical energy. The powerhouse then carries the electricity across power lines through which it reaches our homes.
People have used water power for more than 2,000 years. Ancient Egyptians used water wheels for grinding grain. In the 1880s, scientists learned how to use a flowing river to spin the turbines of a generator. The first hydro electric power plant in the U.S. opened on the Fox River , Wisconsin, in 1882.
The thing is Thomas Alva Edison unveiled the incandescent light lamp only in 1884. But hydro electric energy has its origin in 1882 itself .
It is a well known fact that about one by third part of earth is filled with water. So it is not hard to find water.
Hydro electric energy can be easily explained with a simple example .Consider a dam which is used to trap water. The dam is much thicker at the bottom because the pressure of water increases in depth. Now the water is allowed to flow through the tunnels in the dam. Because of the great height of the water, it will arrive at the turbines at high pressure, which means that we can extract a great deal of energy from it.
As we are running out of the fossil fuels we are in need to move for renewable energy. As it is said before hydro electric energy is the most widely available renewable energy, hydro electric power can be able give a promising future.
