The given graph delineates information about utilisation of energy in the United States of America from the period of 1982, present time. Further more, it also gives predictions for the same till the year 2030.
At first glance, it can be seen that graph provides information regarding different sources of energy which are as follows, petrol and oil, coal, natural gas, nuclear energy, solar wind, power, hydro power. Among the sources, maximum change can be seen in petrol and oil, whereas in case of hydropower There is a negligible change.
Firstly, utilisation of petrol and oil was nearly 35 quadrillion units in 1980 and after some fluctuations in preceding years, it surged up to 40 units in 2010 whereas, its projected utilisation in 2030 is nearly 50 quadrillion units. There was a kind of static arise in consumption of coal as it rose from 15 units approximately in 1980 to nearly 23 units in 2010. However, it might climb to around 30 units till the year 2030. in case of natural gas consumption, it remained unstable throughout the time period from 1980 to 2010 however, projections for future are static and its consumption will be nearly 25 units till 2030.
Further more, utilisation of nuclear power was nearly 4 units in 1980, which showed a minute change and rose to 7 units approximately in 2010 and future predictions for the same are nearly 8 units until year 2030. Consumption of hydro power was about four units in 1980, which came up to nearly 5 units in 2010 and according to projection, it will further rule to nearly 6 units in 2030. Lastly, solar or wind energy consumption was same as nuclear energy in 1980 later in 2010. It came up to 5 units approximately and it will further go to nearly 6 units till 2030.
