Current Situation of Energy Consumption and Carbon Dioxide Emissions of Our World

Abstract

Both primary energy consumption and carbon dioxide emissions in the world increased continuously showing the same trends because nearly 90% of primary energy consumption was fossil fuel combustion. Only the economic depression of the world led to suppression of increases in primary energy consumption and carbon dioxide emissions. Primary energy consumption and carbon dioxide emissions of developed countries kept high levels and those of developing countries increased with higher rates after 2000. Primary energy consumption and carbon dioxide emissions of developing countries exceeded those of OECD countries in 2010, but their populations were 78.0 and 18.1% of world population in 2015, respectively. If all people in the whole world are allowed the world average primary energy consumption and carbon dioxide emissions per person in the world, developing country people are allowed almost 1.5 times as high as energy consumption and carbon dioxide emissions per person in 2015, while OECD country people must decrease 60% of the values in 2015. Furthermore, the world population is increasing at a constant rate of 83.1 million every year. Because the increase in the primary energy consumption is necessary for industrial and economic development, only the solution for prevention of further increase in atmospheric carbon dioxide concentration is to use renewable energy without fossil fuel combustion.
