What is hydel power in geography class 8?
Hydel power is the energy possessed by river water (stored in dams) or rain water falling from great heights. One-fourth of the world’s electricity is produced from hydel power.
What is hydroelectricity for 4th class?
Hydroelectricity is the term referring to the production of electrical power through the use of the gravitational force of falling or flowing water.
How is hydel power generated?
hydroelectric power, also called hydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity.
How is hydel power generated class 8?
Hydroelectricity is produced by utilizing the gravitational force of falling water. To this end, the hydropower plant requires a dam. This dam is placed on a source of water, preferably a river. The dam is a massive wall that blocks the flow of the river, therefore, a lot of water collects behind the dam.
What is drilling Class 8 geography?
Drilling: When deep wells are bored to take out the mineral, the process is called drilling. Petroleum and natural gas are extracted by this method. Quarrying: When minerals are simply dug out from near the surface, the process is called quarrying.
What is coal class 8 geography?
Answer: Coal is a source of energy in most industries. It is also used as raw material for several important industries.
Is hydel power conventional or nonconventional?
Hydropower plants convert the potential energy of falling water into electricity. This is a traditional source of energy.
What is hydroelectric energy BYJU’s?
Hydroelectricity refers to the generation of electrical power by the use of hydropower. Hydropower here mainly is the gravitational force of falling water. This does not use any water in energy production. The average cost of electricity for a large hydropower plant is very less.
Which country is the largest producer of hydel power?
China
China produces the most electricity from hydroelectric power, some 856.4 billion kilowatt hours a year – more than double the amount produced by Brazil, in second place. The top three is completed by Canada, which produces 376.7 billion kilowatt hours a year.
What is petroleum Class 8 in geography?
Petroleum is a dark coloured,thick crude oil found deep below the ground in certain areas. The name petroleum means rock oil.It is called petroleum because it is found under the crust of earth trapped in rocks. 1)Petroleum is a complex mixture of compounds which are made up of only two two elements:carbon and hydrogen.
What are the pros and cons of hydro energy?
Hydropower has several pros and cons that make it an interesting choice depending on each situation. Some hydropower pros are nearly continuous energy supply, low maintenance cost, and a renewable energy source. Some hydropower cons are high upfront cost, impact to ecosystems, and need to store the energy created.
What are the advantages and disadvantages of hydroelectric energy?
Two primary disadvantages of hydroelectric power include the high investment cost and its reliance on precipitation. Hydropower facilities can have a negative impact on the environment, despite not causing pollution, including the loss of fish habitats, displacement of the local population and the inundation of surrounding land.
What is hydroelectric used for?
According to National Geographic, hydroelectric power is used to power homes, offices, factories, hospitals and schools. It is also one of the first methods developing countries use to bring affordable electricity to rural areas.
What is a hydroelectric turbine?
hydroelectric turbine – turbine consisting of a large and efficient version of a water wheel used to drive an electric generator Francis turbine – a type of hydroelectric turbine turbine – rotary engine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate
