The population of the world as of 2013 is around 7 billion, and a lot of energy is being consumed and used on a daily basis by the global population. There is a close association between the economic growth of a nation and the availability of energy. For modern economies, energy can be said to be the lifeblood. Consumption of energy in a nation has a direct impact on its GDP. (“Gross Domestic Product”). More quantity of energy sources if a nation has, higher will be the productivity, more luxurious life and greater standards of living. Energy is consumed in various guises all over the world. Agricultural residues, animal waste, and fuelwood are some forms of customary sources of energy, which are non-commercial fuels that cater to the vast requirement by the society in earlier days. However, these non-conventional energy sources are slowly substituted by commercial fuels like lignite, coal, natural gas, petroleum products, and electricity. Global revenues earned on the sale of energy are estimated at $ 3 trillion dollars per annum, and about 85% of the aggregate energy consumed in the US comes from fossil fuels. (Janardhan &. Fesmire, 2010, p.4).
This research essay will analyze the traditional source of energy and how it is impacting the societies and environment, and also will discuss in detail about the renewable energy and whether such renewable-energy impact the environment or not.
About 80% of the world’s energy demand is being met by conventional energy sources like coal, petrol and natural gas and in the USA, more than 85% of its energy comes from conventional energy sources. However, using a higher quantum of conventional energy will have negative impacts too. The higher usage of fossil fuels releases dangerous emissions into the earth’s atmosphere, .which could cause many lung-related diseases like tuberculosis, asthma, etc. . .
