Advantages Of Hydroelectric Power Production And Usage
3 of 10 advantages- …Hydroelectric power plants with accumulation reservoirs offer incomparable operational flexibility, since they can immediately respond to fluctuations in the demand for electricity. The flexibility and storage capacity of hydroelectric power plants make them more efficient and economical in supporting the use of intermittent sources of renewable energy, such as solar energy or Aeolian energy.
…River water is a domestic resource which, contrary to fuel or natural gas, is not subject to market fluctuations. In addition to this, it is the only large renewable source of electricity and its cost-benefit ratio, efficiency, flexibility and reliability assist in optimizing the use of thermal power plants.
…With an average lifetime of 50 to 100 years, hydroelectric developments are long-term investments that can benefit various generations. They can be easily upgraded to incorporate more recent technologies and have very low operating and maintenance costs.>>
civilengineersforum Hydropower is the energy generated by the water power, using gravity and buoyancy waterfall. It is the most used form of renewable energy. Once built, a hydropower plant, it produces energy without emitting greenhouse gases compared to fossil fuels.
1 of 8 advantages – The maintenance cost of such sources of “green energy” is very small, since the equipment is automated and does not require a large staff during power generation;
1 of 6 disadvantages- …Water accumulation can lead to thermal and chemical changes, in the depth of the reservoirs. Deposits, sediment, reached bottom may encourage the developmental accumulation of aquatic flora (plankton, algae) which under certain conditions can cause atrophy accumulation – reducing the amount of oxygen and death of wildlife. Also great accumulations can cause local climate changes primarily due to water evaporation (fog); >>
technologystudent 2 of 7 advantages- …When in use, electricity produced by dam systems do not produce green house gases. They do not pollute the atmosphere.
…If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high.
3of 8 disadvantages- …People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead.
…The building of large dams can cause serious geological damage. For example, the building of the Hoover Dam in the USA triggered a number of earth quakes and has depressed the earth’s surface at its location.
…Dams built blocking the progress of a river in one country usually means that the water supply from the same river in the following country is out of their control. This can lead to serious problems between neighbouring countries. >>

Top 10 Things You Didn’t Know about Hydropower
Number 10 of 10- Hydropower is one of the oldest power sources on the planet, generating power when flowing water spins a wheel or turbine. It was used by farmers as far back as ancient Greece for mechanical tasks like grinding grain. Hydropower is also a renewable energy source and produces no air pollution or toxic byproducts.
