However, te adverse environmental effects of geothermal energy sources are varied and substantial, rcords Abbasi. Tey include surface disturbances, pysical effects caused by fluid withdrawal, nise, termal pollution and release of offensive chemicals. I is important to note that geothermal plants differ in terms of the technology they use to convert the resources to electricity; drect steam or flash or binary and the type of cooling technology, b it water or air. A such, evironmental impacts differ depending on the conversion and cooling technology applied. Hdropower refers to the of water to produce electricity.
Te hydroelectric power plants use dams to store water which is released from behind the dam flowing through a turbine. Te water then spins the turbine, trning a generator to produce electricity. I is one of the least expensive sources of electricity. Nt only does the dams provide power but also other substantial benefits such as recreation opportunities on upstream reservoirs, hbitat for aquatic and terrestrial organisms, dversion of water for irrigation and control of destructive flooding. Te environmental impacts of dams vary widely, current regulations and policies have attempted to address the issues.
Fr example, fsh migration has been having been addressed with the use of fish ladders and other structures. I conclusion, rnewable sources of energy provide a better alternative to the conventional energy sources, a least with the aim of curbing global warming and pollutant emissions. Ashift from the fossil fuels to the renewable sources, terefore, pomises a healthier environment. Hwever, tere seem to be other factors such as economic growth, ppulation, ad consumption of the energy and other resources are proving to be hindrances in this mission of relieving the overburdened Mother Nature.
Uless there is a reduction in energy use and other resources, rnewable energy alone cannot achieve this mission of combating global warming....
