Meaning of Hydro Power
Hydro Power Hydro power is a power which is produced by the energy of water which is falling from a height or water that is running very fast.
Advantages of hydro power.
- In the production of hydro power there is no air pollution.
- It can be used domestically thereby not always relying on international fuel sources.
- It relies on water cycle, hence making it very affordable.
- It helps in controlling floods.
- Sustainable fuel source.
- Economical since the amount of money needed to operate and maintain dam is little.
- Renewable.
- Flexible. Adjusting both water flow and output electricity is easy.
- Hydroelectricity is must safer compared to other fuel fossils and nuclear energy
- Irrigation.
- Creation of dams is not easy, however, when established, it i very easy to divert flow of water from one place to another or store water for usage when there is water scarcity.
- Tourism and recreation center. E.g Fishing, Boating and Swimming.
- Supply of water.
- All hydro power stations are required to allow people to visit reservoirs.
- They provide backup power when there is power disruptions or outages.
Disadvantages of hydro power.
- Cost of constructing power plants is generally very high.
- It has environmental effects because it interferes with nature due to damming of water and changing water flow.
- Displacement of people.
- During breeding, several species of fish are forced to swim against the water stream since the dams create hindrances in their paths.
- Places to construct dams are limited.
- Affects the quality of water and control.
- When new dams are constructed they affect environment locally andthere might be a competition with other uses of land.
- Limited number of reservoirs.
- Plants that usually decay in an anaerobic environment due to the floods caused by dams results in production of greenhouse gas and methane.
- Construction of hydro power dams is set up at the cost of moving the population of the site of the reservoirs.
- Aquatic Eco-system is highly affected.
- In places where people depend on hydro power only may face major issues when there is water scarcity.
