How to work Hydropower or Hydroelectricity

Hydropower or in a other mean hydroelectricity refers to the conversion of energy from flowing water into electricity. It is considered renewable energy source because The water cycle is constantly renewed by the Sun.

All Advantages and Disadvantages of Hydropower Energy

One of the first uses of hydro energy was for mechanical milling such as grinding grains. However, today modern hydro plats produce electricity using turbines and generators. The mechanical energy forms by moving water spins rotors on a turbine. Afterward, the powerful turbine is connected to an electromagnetic generator which produces electricity when the turbine spins.

 

There are Two Main Types of Hydroelectricity Production

 

They are dams and run of river. Therefore hydropower dams prefer the potential energy from dammed water to produce electric energy. A dam is a large barrier constructed because, aim is to raise the level of water and control. Thus, its flow and elevation created by the dam creates gravitational force for turning the turbine when water is released.

Some dams also contain an additional reservoir at their best where water is storage to be pumped to the higher reservoir for release when electricity is in demand. Also, this is referred to as pumped-storage. The second form is hydroelectricity production is run of river hydro runoff river still uses turbines and generators. However, natural water flow rates of rivers diverting just a portion of the water through turbines. Because hydropower is subject to natural water variability. Therefore, it is more intermittent than dammed hydro there are various huge hydro plants that produce electricity.

  • Large hydro greater than 30 megawatts.
  • Small hydro 100 kilowatts to 30 megawatts.
  • Micro hydro less than 100 kilowatts

The Hoover Dam in the United States is a whopping 2074 megawatts. It is enough to serve 1.3 million people of all renewable energy sources hydropower holds largest share of worldwide electricity production.

Hydropower has Many Benefits

  • It is cost-competitive.
  • It is reliable
  • Base-Load Power
  • Flood Control
  • Water Supply

There are also some concerns with hydropower. Especially, when it comes to large dams. Also, changing wildlife habitats blocking fish passage and often forcing people in riverside communities to move out of their homes. In addition, dam failures can lead to environmental disaster claiming the lives of those living downstream. Hydro plants are also not completely free of greenhouse (no C02) gas emission. Its mean the renewable energy power has no harmful.

As with most forms of energy, carbon dioxide (C02) emission happen during the construction. Therefore, plant matter in the flooded areas makes methane.
