Hydroelectricity pros and cons
Controversy over alternative energy (part 1)
Hydroelectricity and evaporation water supply
Hydroelectricity is also linked to disrupting aquatic ecosystems. It interferes with aquatic life and results in huge scale devastation. With that, also it leads to water stagnation. Stagnant water is when water stops to flow and it can be a major environmental hazard, a breeding ground for mosquitoes and parasites, an incubator for many kinds of bacteria and diseases and illnesses like malaria and dengue fever in hot countries where the temperature is ideal for it. Hydro-power plant dams are usually built across rivers to stock large bodies of water in a basin. The water loses is good proprieties, lose oxygen, sediments start to build, water stagnated and that's very bad for the ecosystems and the environment. It had been found that a lot of individuals, fishes, and others aquatic animals will perish in there by the lack of oxygen and impossibility to reproduce in their native habitats. There is a huge probability also that the fish and other aquatic creatures will find a way into the penstock pipes then to the turbines and get exterminated.
Renewable energy debate
Hydroelectricity may not be the perfect alternative energy source and the answer to all of our environmental problems. If greenhouse gases are our big concern and the control of global warming our first priority today, hydroelectricity is maybe not the final solution for to save the environment and the planet.
