Advantages and disadvantages of hydropower

Energy consumption makes up a big part of our daily lives. We use energy for numerous functions including heating, traveling, working, and even flirting.

The question is; where does this energy come from? Today, most of our energy needs are met by fossil fuels including oil, coal and natural gas. We also get part of our energy from nuclear, biomass and renewables. While fossil fuels are the main source of our energythey cost more at the pump and affect the environment in numerous ways.

These effects include global warmingdegradation of air qualityacid rain and oil spills. Nuclear energy also comes with a host of problems including dangerous radioactive waste and nuclear radiation hazards.

Advantages and disadvantages of hydropower

The solution squarely lies in renewable energy resources such as solar, wind, geothermal and hydropower. Of all the renewable sources of energyhydropower is the largest and oldest power source in the world.

Hydropower is obtained by harnessing the kinetic energy of flowing water and converting it into electricity for a variety of home and commercial applications. It qualifies as a renewable energy since the water cycle is continually renewed by the sun.

Countries such as Canada, New Zealand, Brazil, Switzerland, Venezuela, and Paraguay generate majority of their electricity through hydropower. Hydropower was utilized as far back as ancient Greece by farmers for mechanical tasks such as powering watermills to grind grains. However, cheap electricity has made these watermills redundant in the modern day.

Today, the largest hydropower plant in the entire world is the Three Gorges Dam in China. 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.

There is a huge probability that the fish or other river animals may find way into the penstock and eventually into the turbines where they will be exterminated. Construction of dams in specific places can interfere with the mating patterns, seasons and breeding areas of the water animals. In some instances, these animals are left with no choice but to swim against the water stream when breeding season comes.

In some occasions, dams are built in the path of migrating fish. This means their path to the feeding grounds is cut off leading to their deaths.

This could drastically bring down the population of fish. Constructions needs a large area To be able to construct a dam, install power production units, plus transformers, and tether them to the main grid requires a large piece of land.Advantages of Hydropower: Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas.

Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources. While hydropower energy has some noted disadvantages, its advantages are far greater.

It’s a renewable resource, which means it will never end, giving it a sense of reliability. Hydropower is also safe since it doesn’t involve combustion of fossils fuels. Although the initial costs of construction are high, the long-term benefits are immense including flexible and cheap source of electricity for many years.

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.

The advantages of hydroelectric power are that it is a renewable energy source, it uses naturally flowing water and it helps to reduce greenhouse gas emissions. It is also reliable and has low operational and maintenance costs.

Advantages of Hydropower: Hydro power is a very efficient source of renewable energy. Hydropower systems are very efficient because of the density of water, the force of gravity and the technological advantages of today.

These systems can covert up to 90% of the energy of water into electric energy, which is an astonishing number. Advantages of Hydropower: Hydro power is a very efficient source of renewable energy.
