What is hydro power development?
It is obvious that hydropower development is a renewable energy source, and that its renewability is a significant advantage. When hydropower development occurs at existing dam sites, the environmental impact is minimal. However, significant changes can occur when an existing dam site is developed for power generation.
Why is hydropower development important?
1) To provide safe, reliable, sufficient and affordable electricity for domestic consumption and industrial use. 2) As an industry for earning revenue from export of hydroelectricity thereby providing the much needed capital to finance social projects and achieve economic self reliance.
What is hydropower simple words?
The definition of hydropower is hydroelectric power, which is electricity produced by water. An example of hydropower is the electricity produced by a water channel turbine.
How does hydro power work?
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
Why hydroelectricity is the best?
Hydropower produces no air pollutants and has ultra-low greenhouse gas emissions. … Converting over 90% of available energy into electricity, hydropower is the most efficient source of electrical energy. By comparison, the best fossil fuel power plants operate at approximately 60% efficiency.

How does Bhutan generate electricity?
Power generation in Bhutan relies almost exclusively on hydropower. The total installed capacity of existing hydropower plants is 1,488 megawatts (MW).
What is example of hydropower?
This fast flowing water turns the turbines, and the generator system converts this kinetic energy into electrical energy. An example of a hydroelectric power dam, is the Kielder Water reservoir, located in Northumberland, operated by RWE Npower and is the largest system in England.
How hydroelectricity is produced?
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.
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.
