List of Pros of Hydroelectricity
1. It is Renewable.
Since this method uses water from the earth to produce electricity, the resource is renewable. Naturally, water that evaporates from the surface of the earth will form clouds and eventually falls back to the earth formed as snow or rain. This means that it will never have to run out of supply and it will not become scarce.
2. Source of Clean Energy.
Basically, hydroelectric power is a clean and green alternative source of energy. In fact, the creation of hydroelectricity will not cause any contamination. Moreover, it will not produce any greenhouse gases or toxins that will pollute the environment.
3. It is Stable and Reliable.
This type of energy source is considered dependable as there are no issues so far as electric power generation is concerned. Many countries with huge hydropower potential utilize hydroelectricity as their main energy source.
4. Requires Low Operating Cost.
The good thing about hydroelectricity when it comes to cost is that it requires low maintenance and operating cost. It also require minimal replacements due to the fewer parts that are present in it. More so, the dams built in these locations have been designed for long-term use. Hence, these facilities will be capable of providing hydroelectric power for a long period of time.
5. Matches Current Demand.
Altering the water streams, creating dams, and getting power can be easier said than done. However, it is not very hard to get going. Once the establishment is in place, it will be easier to deflect the flow of water from one place to another. For instance, if the demand for water is low in a particular area, it will be lowered, redirected and stored until the need arises.
List of Cons of Hydroelectricity
1. Causes Environmental Damage.
Due to the interruptions in the natural flow of water, there are many identified results that can affect the environment. Consequently, it can influence the movement of fish as they move or migrate. This is because fish environments can be influenced with a number of factors, including safe spots, water levels, and water speed. When one of these factors will be altered, there can be a possible interruption in the ecosystem for sure.
2. Cost of Building is Expensive.
Undoubtedly, power plants are very expensive to create, regardless of the type of building. Although hydroelectric power plants are not that complicated to build, it may still require a huge amount of money to begin with. The only advantage is that it will not require specialists to maintain or support personnel that need to be paid large sums of money. So perhaps it will make a good investment to think it can provide an essential source of energy.
3. May Cause Droughts.
A great possibility that happens when building hydroelectric power plants is the occurrence of local droughts. The cost of energy and power are identified depending on the accessibility of water. This can be greatly influenced by a dry spell, causing people not to acquire the power they need.
4. Floods in Lower Areas.
Local populations in low lying locations can become victims of floods due to possible strong water currents that might be released from the dam. More so, it can affect the livelihood of people living in these areas. As a result, more people are then forced to move out to pursue the construction of the dams needed for generating hydroelectricity.
5. Shortage of Water Supply.
Huge dams are built across rivers in countries rich with potential hydroelectric power source. This can cause the interruption of the natural flow of water from one direction to another. When one location does not require too much water supply, it will be redirected to another place so that those looking to build dams in the area can get the much needed water. However, it can cause conflict in the long run when there is scarcity of water supply in that particular area and the water redirected to the dams must be stopped.
