Hydroelectric power, on the other hand, can also result in land wastage and the dams often result in depreciation of water levels and drying up of rivers drastically affecting aquatic life forms. Biomass combustion and geothermal plants release greenhouse gases in qualities that are comparable to coals as well as sulfur and nitrogen dioxides which pollute the air and cause acid rain. Finally, there is nuclear power, which poses catastrophic threats in case of accidents and the release of radioactive water and gases into the atmosphere in addition to the production of GHG from emergency diesel engines.
In most of the world’s countries, the primary sources of energy are carbon-based fossil fuels, this is however finite considering the fact that it takes millions of years for them to form although they are depleted in substantially less time. They are gradually becoming harder to extract as well as more expensive and this has in retrospect resulted in political conflict as nation’s battle each other in competition for these resources (Asif and Muneer, 2007). In addition, the environmental impacts of fossil fuels have proved dire owing to the inevitable production of GHGs, which follows their combustion. The corollary has been a myriad of negative environmental effects such as a marked increase in the greenhouse gasses in the atmosphere that is threating to drastically change the global climate. In addition, the CLC that is also byproducts of burning carbon fuels has depleted the ozone layer and this exposes the world to dangerous infrared shortwave radiation, which poses a plethora of health danger for life on earth (Drabyk, 2001). More direct and short term impacts of fossil fuel include massive pollution of air and water the former resulting in acid rain, health problems such as Asthma and the latter mainly merging in oil seepages and leakages in water bodies. The innumerable problems attributed to fossil fuels and their apparent finiteness has necessitated a shift to renewable energy that many touts as the only feasible source of energy. .  .
