When water is allowed to flow over running turbines there is the generation of electrical energy which is referred to as the hydroelectric energy. The use of hydroelectric power as a source of renewable energy dates back to the 1940s where the hydroelectric energy contributed a third of U.S energy needs.The exploration and investment in other energy sources has reduced the dependence of hydropower in the united states to around 6%.
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.
Explained below are some of the pros of making investments on the hydroelectric power generation. To begin with,water which is the basic component of hydropower generation is free and readily available unlike fossil fuels which are expensive and difficult to get. 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%.Thirdly the hydroelectric energy investment is good because the power generation has no water,land or air pollution as compared to other sources of energy that causes pollution and increase global warming.The fourth advantage of investing in the hydroelectric energy is that the process is renewable because when water which is used to run turbines evaporates,it falls back naturally as rain. The fifth advantage of investing in hydroelectric energy is that it greatly make the quality of the environment to be better through creation of farm irrigation opportunities and huge habitats for aquatic life such as fish.The sixth good side of making investments on hydroelectric energy is the ability to continuously meet new demands through putting up additional power plants in the already existing hydropower 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 cons of hydropower generation are highlighted below.To begin with,the hydropower generation contributes to the destruction of natural habitats. Secondly,the process of hydropower generation can emit significant amount of methane and carbon IV oxide when trees and plants in the power plant rots in absence of oxygen. The dependence of the hydropower on heavy rain to optimally generate energy,the risk of flooding it poses on the surrounding settlements and the expensive nature of installation are some other disadvantages of hydroelectric energy investment.
