Whenever water flows over running turbines, there is a generation of electrical energy which is known as the hydroelectric energy. Hydropower is one of the oldest large-scale renewable energy sources which contributed a third of all energy needs in the US in the 1940s.Today the hydropower contributes around 6% of the power needs of the United States because of the increased investment in other energy sources.
The hydroelectric energy has its economic and environmental pros and cons and therefore it is crucial that these aspects are understood before investing in the energy source.
The following are some of the advantages of investing in the hydroelectric energy. First,it uses water a free and readily available resource and therefore there is virtually no cost to be incurred when getting the resource unlike the use of fossil fuels whose price is high and keep on fluctuating. The second reason why you should consider investing in hydroelectric power generation is because of its high efficiency in converting captured energy to electrical energy which stands at around 90%.The third attractive thing about hydroelectric power generation is that it has no water,air or land pollution which makes it better as compared to other forms of energy which contributes to global warming and causes other environmental pollution.Fourthly,the water that is utilized to run turbines when it evaporates,it falls back as rain hence the hydroelectric energy is renewable. The fifth advantage of investing in the hydroelectric energy is that it improves the quality of the environment by contributing to quality water for irrigation and providing larger and better habitats for aquatic life.The sixth advantage of investing in hydroelectric power generation is because of its capacity to keep up with demand by enabling the investor to set up more power plants in addition to the existing dams. The seventh pro of investing in hydroelectric energy is that alongside power generation, you can set up recreational amenities for holidaymakers such as camping, water sports and fishing.The other advantage of investing in hydropower is that it is cost effective when compared to other source of energy such as natural gas and coal.
The following are the disadvantages of investing in hydroelectric power generation.To begin with,the hydropower generation contributes to the destruction of natural habitats. The second disadvantage to hydroelectric power generation is that there are some large amounts of methane and carbon IV oxide emission that occurs when the plants and trees rot without using oxygen around the dam. The other cons that limits the investment in hydroelectric power is the risk of flooding that it poses to people and structures around the dam,its dependence on heavy rain to get more water for maximum power generation and the high cost of installation.
