Write advantages and disadvantages of hydroelectric power plant

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.

Furthermore, it has a damaging effect on the surrounding wildlife due to the power plant causing a change in the water temperature and modifying the river flow.

These effects include global warmingdegradation of air qualityacid rain and oil spills. On their banks to build country houses is not worth it! The water that gets out of the turbine will be returned to the stream found under the dam.

Not only does the local environment suffer but so does the environment of areas downstream.

10 Advantages and Disadvantages of Hydroelectricity

Various Disadvantages of Hydroelectric Power Disrupts aquatic ecosystems Hydropower plants are typically constructed across rivers, and this can interfere with aquatic life and result in their huge scale devastation. This means their path to the feeding grounds is cut off leading to their deaths.

Local populations in low lying locations can become victims of floods due to possible strong water currents that might be released from the dam.

What is Hydropower?

Clearing of forest greatly impacts the natural ecosystems. Aquatic eco-system is one of the major realms which get immensely affected. The plants which get destroyed due to floods caused by the dams, decay in an anaerobic environment. Nowadays there are limited places where we can build new dams that will provide the highest reliability and efficiencies.

Water is a renewable energy source that will never run out and the use of this resource helps to conserve non-renewable energy sources for other uses. The damage caused by this process is considered to more harmful than the forest which would have decayed naturally.

The water is stored in a reservoir and is released downstream through a pipe. Water in artificial reservoirs, as a rule, is clean, since impurities settle on the bottom.

This turns out to be advantageous during times when any compensation for variability in demand from the grid is required.

Hydropower – Advantages and Disadvantages of Hydropower

However, cheap electricity has made these watermills redundant in the modern day. For example, the building of the Aswan Dam in Egypt has altered the level of the water table.

As a result, the magnets in the generator will rotate and produce electricity. We use energy for numerous functions including heating, traveling, working, and even flirting. Once the establishment is in place, it will be easier to deflect the flow of water from one place to another.

The construction of hydroelectric dams is set up at the cost of relocating the population of the site of the reservoirs.Advantages are that it’s cheap to operate, and the power source is renewable.

Disadvantages are that building dams isn’t cheap, there aren’t an infinite (or very large) number of suitable sites, and the presence of the dam and reservoir can have major ecological affects upstream and downstream.

Hydroelectric Energy Pros and Cons Last updated February 21, by Mathias Aarre Maehlum 20% of the world’s electricity consumption in was generated with hydroelectricity (generating electricity from hydropower), the most used renewable energy source in the world.

A hydroelectric power plant requires a water reservoir, the size of which depends on the size of hydroelectric generators and the topography of the land. Creating a reservoir negatively impacts the surrounding area by flooding land that could be used for agriculture instead.

What is Hydroelectric Energy?

Because hydroelectric power plants and dams utilize the flow of water, this also alters the natural flow of rivers. Algal blooms can occur in reservoirs due a lack of dissolved oxygen levels that result in more stagnant water conditions. Read the following paragraphs for some more detail regarding hydroelectric energy advantages and disadvantages.

The Pros As mentioned earlier, this energy works without the use of fuel, like oil, uranium, etc., and this fact makes this energy an inexhaustible fuel source. Creating hydroelectric power plants and dams need a sufficient budget in order to create a high standard hydroelectric power.

Though hydroelectric energy produces a cheap cost, the construction of one dam costs approximately $20 billion and takes 18 years to finish.
