Analysing data

The data shown shows how the primary energy supply sector continues to increase from 1971 to 2013. According to Mitsubishi Heavy Industries the world consumption of primary energy greatly increased from 3.8 billion tons of oil equivalent in 1965 to 11.1 billion tons of oil equivalent in 2007. The supply in the primary energy supply sector has been increasing in step with economic growth. This occurs because energy demand and economic growth have a positive relationship. The Jevons paradox, an economic theory, explains this relationship were the economical use of fuel results not in diminished consumption but in an overall increase (Owen, 2010).  The increase in the supply of energy in the primary sector is owed to the continuous technological development, economic growth and growing populations.

By observing the data shown in the graph, the supply of coal has been increasing since the year of 1971, the graph also shows a higher supply of oil than coal and a higher supply of oil and coal than any other source of energy. There is also a higher supply of every energy source shown in the graph, which is coal, oil, natural gas, nuclear, biofuels and waste. However supplies such as natural gas has increased more over the years than energy sources that pollute our atmosphere, such as oil and coal. The world would most likely continue the trend that has been followed since 1971, where there is a higher increase in supply of biofuels and waste, nuclear, hydro and natural gas than other sources of primary energy.

 It is expected in the future for the increase in the primary energy supply sector to increase because there is a low cost associated with the conversion of natural resources to energy. However, resources are scarce and limited, resulting in a major problem for future generations. Prices in the future for primary energy will increase dramatically because there would be a shortage causing supply to decrease and demand to increase.

However, the increase in the primary energy supply sector has not been uniform throughout the world. The types of primary energy consumed differ among countries. Emerging markets like China and Brazil come to account for a greater proportion of the primary global energy consumption. There are many reasons that can be attributed to an increasing consumption trend in the primary energy sector for developing countries. Emerging markets like China and Brazil have a population that is dramatically increasing leading to a higher demand, more energy is needed to satisfy the needs of more people. Another important cause is industrialisation  because countries like China and Brazil are in the process of becoming developed their energy consumption is higher than that of already developed countries who have already achieved efficiency.

According to The Nature Conservancy my current total greenhouse gas emissions is 24, however in the future it will be reduced to 18 because I am planning to decrease my consumption of energy once I own an apartment. I am currently renting the apartment I live in so it is not up to me to change the appliances, lighting, amongst other things to reduce my carbon footprint.
