Extreme Importance of Alternative Energy Sources Research Paper

Extreme Importance of Alternative Energy Sources - Research Paper Example Forecasts show that coal, gas and oil supplies will last only for a few more centuries. Secondly, the use of fossil fuels poses a serious danger to the environment. The combustion of fossil fuels leads to the emission of chlorofluorocarbons, mainly carbon dioxide. This causes the ‘greenhouse effect’ which traps heat in the earth’s atmosphere, leading to global warming. The combustion of fossil fuels also causes atmospheric pollution and acidification of the environment. The environmental damage caused by oil spills in the wake of the BP oil spill in the Gulf of Mexico is fresh in minds. Likewise, nuclear power is associated with the risk of nuclear accidents, such as Chernobyl and Fukushima, and the problem of disposal of hazardous radioactive waste. As there is no sign of energy use declining in the conceivable future, the environmental impacts of energy consumption, and the depletion of energy sources, assumes grave implications. It is clear that the need for al ternative, renewable sources of energy is the need of the hour. Energy consumption shows tremendous global variation, and â€Å"about a quarter of the world's population consumes three-quarters of the world's primary energy† (UN Document). About 20% of global energy consumption is in the USA. Again, it is estimated that the U.S. is responsible for about one-fifth of all human-produced greenhouse-gas emissions. Renewable sources of energy account for only 9.3% of the total US energy consumption (EIA). In this scenario, it is evident that the need for alternative energy sources should be a high priority for the government of the United States. It is heartening to note that President Obama has declared that â€Å"I know the country that harnesses the power of clean, renewable energy will lead the global economy in the 21st century† (qtd. in Scientific American).
