Hydroelectricity is mostly generated by the building and usage of dams that hold back large quantities of water from traveling down the natural river path. The higher level of water stores massive amounts of potential energy that when released down to the lower level, can be transmitted into mechanical and finally, electric energy using special turbines within the dam. For more information about how hydroelectric power is generated, benefits of clean energy production, possible environmental issues caused by dams, and many other topics, read articles written by experts here on Bright Hub.
Compared to other forms of energy productions, the side effects of hydroelectric power are relatively benign. Some could even argue that the biggest problem with them is that there aren’t enough rivers to cover all of our energy needs with them!
Tidal energy is used to convert the energy in tides into other forms of energy that are useful to mankind, mainly in the form of power through electricity. Such tidal energy had also been used earlier by tide mills mainly to drive flour mills and such examples go back to even Roman times.
There are many possible renewable methods of generating electricity, but sea water is seldom considered a serious option. Here we’ll witness through an experimental set up how this simple method of producing free electricity can be one of the most efficient ones.
Everybody knows about wind, solar, and fossil fuel renewable energy. But how about the ocean? Read on to learn how wave power works, inventions of wave power generators and methods of harnessing electricity from the ocean.
There are various classifications of hydroelectric power plants. Based on the total quantity of water available for the generation of electricity the hydroelectric power plants are classified into three types: Run-off river hydroelectric power plants with pond, without pond, and reservoir type.
There are various classifications of hydroelectric power plants. Based on the total head of water available the hydroelectric power plants are classified into three types: low head hydroelectric power plants, medium head hydroelectric power plants, and high head hydroelectrci power plants.
The hydroelectric power plants don’t require any fuel for generation of electricity, hence they don’t cause any air-pollution. The hydrolectric power plants help in irrigation of the agricultural lands and offer many other advantages. Let us have look at some important advantages.
There are many advantages of the hydroelectric power plants, but there are also numbers of disadvantages of the hydroelectric power plants. The hydroelectric power plants can be dangerous to aquatic life and can cause many other environmental concerns.
The largest hydroelectric power plant of the world is Itaipu constructed on the Parana River in the areas adjoining the borders of Brazil and Paraguay. The plant has been built in cooperation between the two countries. Here are some of the amazing facts of Itaipu hydroelectric power plant.
