Ethic report for wind and solar and hydropower - Essay Example an be produced in different scales namely large hydro (more than 10megawatts), small hydro (upto10 megawatts), micro hydro (up to 100kw), and pico hydro (up to 5kw). One major advantage of hydroelectric power is that the operational cost of a hydroelectric plant is almost immune to the increase in the cost of fossils fuel and, more so, absolutely no imports are required for the same. Hydropower is a clean source of energy with absolutely no emissions of Carbon Dioxide, and, therefore, no pollution to the environment. Global warming is also minimized. The hydropower dams can be used as a habitat for some fish and wildlife. More so, the water can be used for irrigation purposes, and they make the surrounding area around fertile (Ryan, 2009). Additionally, electricity can be produced at a constant rate and electricity generation can be stopped when it is not needed by closing sluice gates. Therefore, water can be stored for some time when there is less demand for electricity. Since dams can stay for a longer period it can be used to, store water there is no high demand of power. It is vital to note that many nations recommend hydropower because it does not emit any harmful chemicals and gases such as carbon dioxide and it is not a major contributor to global warming via carbon dioxide. Hydropower is a renewable source of energy or power because rivers and streams are naturally available. Further, hydropower is not expensive as compared to energy produced from nuclear energy or fossil fuels. The advantage of hydroelectric reservoirs is that they are able to tackle daily, seasonal, and peak loads. For instance, when the demand of electric falls, the reservoirs or dams store water while some installed electricity generators are used to store excess energy (Ryan, 2009). The cost of generating hydropower is low making it the most preferable source of the world’s renewable energy. Further, hydroelectric plants are said to have long economic lives with some plants
