In the age where man is abusing the non-renewable resources, it is also important to see the future. Because of the abuse of power, the future looks problematic too. This means that mankind needs to understand and find better ways of using resources. However, these methods will employ a lot of hard work and also a different thought process.

Meanwhile, what emerges as a running solution is the use of hydropower. After elaborate discussion on hydropower pros and cons, the ides sound reliable too. The idea of having water in abundance and not utilizing it for survival needs attention too. The list of hydropower advantages will also find a lot of voices in support.

The resultants of the man being a selfish being are visible and for open assessment. However, humanity still fails to utilize the available resources, it can be pretty late. The advocates of Hydropower facts understand and interpret this situation. Creating awareness on a public basis is important to indulge in people. To understand an activity that will end saving you thousands of years’ worth of survival is also deserving. Meanwhile, the moment this concept becomes an application on a daily basis, the idea of greener earth is achievable.


It is evident that hydropower usage is also not a new idea. The application, however, may vary for the end result. The water flow requirement also restricts usage. The model is useful for countries near water bodies.

The simpler method involves the use of kinetic energy in the flowing water. This energy is useful as work output. The work obtained in this fashion is usable for the mechanical jobsTask output of sawing, milling, and also the use of elevators, etc. are certain examples too. However, the use of hydropower is much more worthy. In the present situation, the major application is also to generate power (electricity) using this technology.


How It Works

It is desirable either to have enough momentum inflow or provide potential energy. The idea is to convert energy (one form to another form) and also do it efficiently. Meanwhile, due to the variation in flow, kinetic energy is not always usable. This means that the storing of water and then using the potential energy is also advisable. A brief detailing of the hydropower diagram will give clues about the working too.

Most dams work in this thought process too for giving hydropower. The water hits the turbine and imparts rotation too. Meanwhile, as the turbine rotates, the shaft attached to it rotates too. Through a suitable generator mechanism, the turbine further provides electrical energy. Hence, the generated energy goes through the distribution lines. The electricity heads to the grid and further ahead too.


The hydropower also covers up for the mistakes that mankind does. By being near to the never-ending source, the hydropower advantages are high and broad. However, due to the vast difference in geography and also finances, the hydropower pros and cons are under debate. For realizing a practical system of work, it needs a pointwise undertaking. Hence, an elaboration of the points is much needed.


As a common notion, the idea of a renewable source of energy is automatically good. The hydropower advantages by and large also compensate for the fluctuating issues. Meanwhile, the pros of this method of power generation are many. To understand the issue, the comparison with others and absolute descriptions are also necessary.

  1. Availability

In general, hydropower availability is not an issue for most countries. It also depends on the location of water-bodies and seasonal influence. It is notable that the Earth has a lot of water available as resources. Because of this, the availability is not a big concern for even the developing allies.

  1. Long-Lasting

One the establishment sets up, it also lasts for a long period. Because there is not a mandatory requirement to work all year long. The establishments also work mostly on common machinery. This means that durability is another in the list of hydropower advantages.

  1. Global Warming And Emission Reduction Savior

The usual method of electricity generation utilizes natural resources of non-renewable nature too. This means that the emission of CO2 on a large scale basis is pretty high. These emissions are also the notorious ones responsible for global warming across the whole planet. By reducing CO2 emissions, the idea is to slow down and also eliminate the problem.

Meanwhile, a renewable energy resource with not much raw emissions is very useful. That is also the reason for the famous nature of hydropower. The non-renewable fuels and minerals give almost 41-45% of CO2 emission yearly. In contrast, hydropower advantages take care by giving away less than 10% emissions. This means that understanding the hydropower facts also ensures an understanding of global warming reduction.  This helps in creating positive efforts with better results too.

  1. Renewable In Itself

The whole point of using a renewable source is to ensure that we do not harm nature. The self-compensating nature of the water cycle also ensures that the resources stay replenished. In doing so, there is practically a very minor loss of the resource itself. Hence, the application is broadly acceptable.

  1. Freshness As A Resource

Because the resource is relatively a new idea (in comparison) it means that the scope of improvement exists too. By utilization of brainstorming techniques and acts, the scope for new entries is high. Hence, the application of hydropower leaves a lot of scopes open for future interventions too.

  1. Utilization Of Resources

From large-scale plants to hydropower at home, every application is possible and also feasible. What it needs is to segregate the resources, understand them, and analyze them too. Because of the dynamic nature of water, the resources are diverse and applicable at ease. A stream of rivers properly utilized can facilitate the hydropower at home, making it user-friendly too.



Just like every other possible source of energy, Hydropower has cons too. The nature of digging into the query also decides the answer. Meanwhile, it is unfair to assess the application of a particular resource without fair evaluation. Hence, critical and statistical analysis can help the purpose. Listing the disadvantages of hydropower helps for a fair analysis too.

  1. Costly At The Start

People also confuse the cost with only the running expenses. For example, the US shows how a unit of power through hydroelectric resources comes at approx. 0.85 cents.  However, the case is incomplete at that point. In the present system, building a dam is the first necessity for most hydropower setup. Hence the initial cost is a significant block. The average figures estimate the cost of 3-5 million Euros for a 500 kW plant. This is significantly high for investment, especially for developing and also under-developed nations.

  1. Effect On Sea-life Habitat

Studies reveal a lower percentage of sea-life near such constructions. As much as a 20% reduction in schools is visible. Especially the concentration of fishes and much more near the smaller plants. Meanwhile, the flow and velocity and abundance also affect the sea-life. Constant disturbance of sea life also creates an ecological imbalance. This has a major say from the environmental angle for the hydropower pros and cons.

  1. Percentage Contribution In Power Generation

Developed and developing nations alike, the contribution of the overall generation is less. For example, India cites a generation of only 28% through all renewable resources. Meanwhile, the USA also meets only 12% of its electricity demands through hydropower. The figures also play a significant role in the involvement of hydropower on a global level.

  1. Risk Of Scarcity

Another important point for analyzing the hydropower pros and cons is the availability of water. Statistically, a lot of developing countries also face constant drought threats. Because of their need for these countries to search for an alternative source urgently, it is also impractical. The application is suitable for places having plenty of water.



When discussing a topic like hydropower, it is important to discuss the aspect of environmental influence too. Because of the tricky nature of the subject, it becomes essential to weigh the hydropower pros and cons too. By doing so, not only we get a detailed understanding but also a future path too.

Environmental Pros

  • Significant contributor in the renewable energy sector.
  • Highly Helpful in the reduction of CO2 emissions too.
  • Hydropower management is easy and convenient in every method.
  • It does not need the depletion of any non-renewable resource in working.

Environmental Cons

  • Traces of inconclusive evidence about marine-life damage.
  • Possibility of altering flow patterns.
  • Human greed can lead to erosion of forest for infrastructure development.
  • Diversion of essential water sources to the industrial sector.

Because of the immediate threat of global warming subsiding, it is conclusive to term Hydropower as environment-friendly. Since climate change is a bigger issue than any other, it gives a fix. However, the analysis of the hydropower pros and cons also reveals a drastic scope for a better generation. Thus, improvement is the order of the day to make the Hydropower source into a completely friendly alternative.

Long-term Environmental pros & cons


Another chapter in the hydropower pros and cons is to gauge the economic impacts of hydroelectric power. By doing so, it is easier to estimate the profit and loss and hence decide the utility for future reference.

Studies across the US reveal that hydropower stands shoulder to shoulder with other renewable resources. The competition is not only in greenery but also in economic impact. The statistics reveal that for the last financial year, hydroelectric power supplies electricity at almost 0.05 $/Kwh. This amount is tremendously low in comparison to the non-renewable resources. Meanwhile, it is also lower than solar and wind which stand at 0.10$/Kwh.

This means that once ready, the hydropower is also a cheap source to sustain. However, the tricky part is the erecting of the plant. It entirely varies from one country to another and the speed and size too. For example, the research reveals that establishing a plant takes about 2 years and a cost of 3-5 mil. USD. However, the cost can go higher and higher depending upon the size and strength of the dam or storage.

Hence for the longer run, it is more feasible for the developing countries to invest in the source. An analysis of the Hydropower pros and cons is necessary. The length of production through the economic impact of hydroelectric power also makes it feasible.


The case study of the nature and sustainability of hydropower helps in understanding it better. The committee also focuses on the impact of this renewable source of climate. By and large, the understanding is to establish its name as a trustable source too. The article published in 2013 is a path breaker in the field of hydropower research. It finds a critical take on:

research results

  • The clean energy source that can revolutionize the world.
  • Inclusion of capital investment and the unit production rate for energy.
  • The adverse effects on land and forest erosion
  • Restriction of construction due to the populated areas too.

The study suggests how the application of hydropower can bring about a revolution in the process of thinking. Sustainability through continuous improvement is also a big challenge. This makes it a clear idea that hydropower is the look into the future through continuous improvement.


While mankind searches for optimum methods to cover-up, Hydropower comes in also as a savior. The idea is to understand the need and the application and act accordingly too. In the greed of more, we can often end destroying the essence of the resource. Hence, to maintain a perfect balance, hydropower pros and cons analysis light up the way ahead. The usage of this method is also the outlook of the future of human survival.
