The water then spins the turbine, turning a generator to produce electricity. It is one of the least expensive sources of electricity. Not only does the dams provide power but also other substantial benefits such as recreation opportunities on upstream reservoirs, habitat for aquatic and terrestrial organisms, diversion of water for irrigation and control of destructive flooding. The environmental impacts of dams vary widely, but current regulations and policies have attempted to address the issues. For example, fish migration has been having been addressed with the use of fish ladders and other structures. In conclusion, renewable sources of energy provide a better alternative to the conventional energy sources, at least with the aim of curbing global warming and pollutant emissions. A shift from the fossil fuels to the renewable sources, therefore, promises a healthier environment. However, there seem to be other factors such as economic growth, population, and consumption of the energy and other resources that are proving to be hindrances in this mission of relieving the overburdened Mother Nature. Unless there is a reduction in energy use and other resources, renewable energy alone cannot achieve this mission of combating global warming. How to Reduce Environmental Pollution Using Alternative Energy Sources.
