Are alternative energy sources the answer to ending human dependence Thesis

Are alternative energy sources the answer to ending human dependence on oil - Thesis Example As such, it is necessary to emphasize the fact that the environmental crisis is not only about environmental problems, but it is about the intertwined concerns regarding politics, economics, society and ideologies (Bodley 2008, p. 43). In this regard, this research will try to address one of the most urgent environmental issues that we are facing: are alternative energy sources the answer to ending human dependence to oil? This is a crucial question because the reality of human dependence to oil is attested by the fact that countries all over the globe have to ensure energy security to sustain their economies and in case they fail, the threat of conflict becomes inevitable (Moran and Russell, 2008). Furthermore, as of 2009, 85 percent of total primary energy consumption involves the use of fossil fuels – oil, natural gas, and coal (Statistical Review of World Energy, 2009) and this is a critical issue because oil is finite. In addition, the peril of global warming coupled with the probability of the increase in consumption in the coming years creates urgency in addressing the question are alternative energy sources the answer to ending human dependence to oil? Everybody, in one way or another, is concern with global warming and in finding the answer on how consumption of fossil fuels may be reduced. Alternative sources such as oil sands, heavy oil, and wood/other biomass, coal hydropower, shale oil, solar energy, gas hydrates, wind energy, nuclear fission, wave energy, geothermal tidal power, fusion, ocean thermal energy and conversion are all considered as alternative sources of energy. However, can they end human dependence in oil? First, as mentioned, oil is finite. There is a need to come up with alternative sources of energy because the reality of diminishing fossil fuel supplies is a fact. The fossil fuel that the world is currently using is built on 500
