Basically, hydroelectric power is a clean and green alternative source of energy. The turbine drives the alternator coupled with it and converts mechanical energy into electrical energy. It is Stable and Reliable. Extra Questions – Sources of Energy – CBSE Class 10 Science According to new CBSE Exam Pattern, MCQ Questions for Class 10 Science pdf Carries 20 Marks. In fact, the creation of hydroelectricity will not cause any contamination. Hydroelectricity is very reliable energy. 1- We can simply classify hydropower plant, according to facilities for generating hydropower (the way of operation of the plant) into four main types: Impoundment plant (storage hydropower plant): This facility is a large hydropower system which uses dams to store river water in a reservoir, then we use this water to turn turbines which in turn rotate the generator to produce … Hydropower is produced in 150 countries, with the Asia-Pacific region generating 33 percent of global hydropower in 2013.
Countries that have large resources of hydropower use hydroelectricity as a base load energy source. Hydropower here mainly is the gravitational force of falling water. The electric current can be - AC current or DC current. In simple words, falling water spins the water turbine. Types of Generators Generator is used to generate electric current. The dam stores lots of water behind it in the reservoir. Recycle: This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesising or extracting fresh plastic, paper, glass or metal. Share with your friends. Hydroelectricity refers to the generation of electrical power by the use of hydropower. It is usually made with dams that block a river to make a reservoir or collect water that is pumped there. A power plant that produces electricity by using flowing water to rotate a turbine (which drives the generator), is called hydro-power plant (or hydroelectric power plant). In both cases a power source is used to turn a propeller-like piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. Topics and Subtopics in NCERT Solutions for Class 10 Science Chapter 14 Sources of Energy: Section Name Topic Name 14 Sources Of Energy 14.1 What Is A Good Source Of Energy? Thus, Electric Generators is of two types
Reduce: This means that you use less. So just how do we get electricity from water? Near the bottom of the dam wall there is the water intake. Hydroelectric power plants are usually located in dams that impound rivers, thereby raising the level of the water behind the dam and creating as high a head as is feasible. Then the kinetic energy of flowing water used to generate electricity. HydroElectricity may be extracted from water but it depends not only on the volume of water but also on the difference in height between the top of the penstock and where the water spins the turbine. This is the basic “working principle of hydroelectric power plant”.
