BENEFITS (ADVANTAGES):
Renewable source of electricity. Hydropower plants can produce electricity at a constant rate from water without the water getting consumed. This could be a great infinite source of electricity when the extraction of petroleum reaches an end.
Significant source of energy. Hydropower plants in 2009 were providing almost 16.5% of the global electricity production which is equal to 3 329 TWh. This is around 85% of the total renewable electricity generation.These statistics are expected to increase as the governments and investors are now more into hydropower energy since its clean reliable and affordable.

Hydropower plants have long been promoted as providing cheap energy and water supply and is the most efficient way of producing electricity as 90% is converted into electricity whereas fossil fuels are only 50 % efficient. On the other hand, Installing and running hydropower plants is really expensive for the governments as that requires a huge amount of energy which not all governments can afford.
Dams can cause political conflicts. If a country build a large dam on a river which also passes through the neighboring country may cause serious political conflicts between the two countries, especially if its poor countries since the dam would block the water supply from the same river in the neighboring country. This was about to lead a war between the countries Sudan and Egypt.
The creation of Dams helped in stopping the more dangerous sediment from hurting the flow of the water. Sediment became one of the main problems with the construction of dams within the Yuma project. Which can clog waterways that can give filtered drinking water as well as harming the wildlife within the water. It can also cause for the water to be dirty and as well as affect the cost of filtered water by increasing it. Another positive that the Yuma Project made was that it had offered to give hydroelectric power which better powered all of Yuma.
Throughout the centuries, humans have been attempting to find a way to power homes, cars, and other luxuries in the most efficient way possible. Coal and oil were two major sources that begin being exploited during the industrial revolution. Both have caused great controversy over the years from lawsuits to strikes. A new way to drill oil, hydraulic fracturing, was discovered and was an efficient means of drilling until its effects became prevalent. Also, when coal began to run out, a new method called mountaintop removal took hold, but continues to damage the earth.
As a result, this will allow for a natural filter. This will create a possible water source that is safe for humans to drink. Therefore, this river has a lot of instrumental value if the dam is removed. Also, some aquatic plants will make a shorter life because they won’t be able to survive in the fast moving
However, a careful analysis of the reasons behind the creation of the dam and how the dam was built without much damage to the environment itself, as the system relies entirely on gravity to deliver this water; therefore no pumping stations were necessary, then it is very likely that the decision to build the dam was the correct one. The O 'Shaughnessy Dam is a vital component of the Hetch Hetchy Valley water system that provides water to the San Francisco Bay Area and surrounding communities. Nearly “2.4 million people rely upon the dam,” for their supply or electricity and water (Crabtree, 2013). The demand for the damn came about as a result of the idea during the progressive era in the United Sates that the introduction of public works to certain areas was the most beneficial ways in building a great civilization.
Some might ask why Hydrofracking is positive. Well there can be many reasons. People only hear the negative effects of fracking because when people want something changed they usually tend to leave the positive part out. New York has recently been head of a massive debate among the people and the energy companies. The technology used in hydrofracking is very advanced and has the potential to drastically reduce our reliance on foreign fuel imports.
An uneven distribution of fresh water around the world also causes an increase in humanitarian organizations. The organizations help bring safe drinking water to developing nations and disaster areas. Still, not all people are peaceful. For example, when Egypt felt exposed to Ethiopia altering the Nile, they threatened to use military power. Another example is in Central Asia, the arid climates in some of the former Soviet Union countries causes a lack of water, leading to
Electricity, oil and coal, Tibet might soon become an industrial wasteland that once thrived with its pristine land and now China plans on making it a pure industrial area. (Source G). Chinese geologists are using the uranium to create nuclear power plants and leave the waste on Tibet plains where locals get diseases from radiation. Hydroelectric schemes have been built on Tibetan rivers, which are destroying many rivers; it could “create one of China’s worst ecological disasters of the 21st century. (Source B).
It uses flowing water to generate electricity. It does this by using dams and reservoirs for storage. This method gives us the most electricity rather than any other renewable energy source. Not only do the dams and reservoirs create electricity, they also control flooding (Sambu). Hydropower is the least expensive procedure to generate electricity.
With The motion of the turbines, the mechanical energy is then harnessed into electrical energy from the generator in the dam. Kentucky has three hydro-powered dams since 2014 so this means that Kentucky already has experience in this for of
The two agencies that were involved with the construction of the water projects were the Army of Corps of Engineers and the Bureau of Reclamation. The development of many waterways was highly important for the main exports of the U.S food and crops. The reason why the Crop of Engineers and the Bureau of Reclamation began to build more water projects was due to the growing country. For the growth of the country it needed to have more hydroelectric power and irrigation. This created a conflict between the Bureau of Reclamation and the Corp of Engineers because both ended up competing for the water projects that needed to be done.

The Hetchy Dam controversy of the early 1900’s was a debate that shaped how America has dealt with the environment since. The debate featured those for the proposed dam the conservationists and those opposed the preservationists. These arguments were brought before congress to make a decision about the fate of the valley. The debate over the Hetch Hetchy dam was about whether preserving the environment the way it is or using our natural resources efficiently had more value to human society.
In addition, many African rivers and waterfalls could be used to produce hydroelectric power. Africa
Almost none of the fuel sources that we could use provide Co2 or other pollutants. Economic values could also come from renewable energy. Most of the Energy projects are located away from big cities. These benefits could bring local service as well as tourism. Although the pros are very big there are some cons.
Water pollution is a serious issue as not only is water the most precious natural resource, but all sources of water support life that is very necessary for the survival of the planet. Water pollution destroys life and ecology and such damage is irreparable. Those who are still not serious about water pollution must also remember that the pollutants present in water not only destroy the life in the rivers and oceans, but also affect our food chain. Many people have the wrong notion that since they are not disposing the pollutants in the water they are not to blame. These people forget that 70% of the earth is covered by water, and any activity on the land can wash to the seas and oceans.
