A comparative study on energy review among the developed and emerging nations.

Md. Uzzal Hossain, Liu Meng


The study explored the comparison of energy scenario and CO2 emission among the developed and emerging nations such as USA, Canada, China, Brazil and India. It is recognized that the world is under serious threat of global warming, thus immediate actions are required to combat against it globally. The objective of this study was to examine the current situation of energy and emission in this high energy consumes countries. Total global coal production has been increased up to 35.36% in 2010 compare to 2001, and 5.5% increased compare to 2009. The production of natural gas has been increased in a similar manner. China alone contribute 26% of the world total CO2, USA 18%, India 5%, Canada and Brazil 2% in 2009 due to the high consumption of coal, natural gas and petroleum. But the per capita emission of CO2 was very high in developed countries such as USA’s per capita emission was more than 3, 13 and 7 times than China, India and Brazil in 2009. So it is very important to adopt low e-technology and energy efficient initiatives in the energy and emission driving countries.
