the graph illustrates statistics from a 2008 outcome related to utilization of energy in the America, which are Petrol and oil, coal, natural gas, nuclear, solar, and hydropower since 1980 with future predictions until 2030.
Overall, it can be observed that consumption of petrol and oil had by far the maximum figure as compared to others and will follow the same pattern in future as well, whilst nuclear and wind hydropower was same in history and shows the nearly same projections.
In 1980, the usage of coal and natural gas was relatively same units, coal which was 15 units in the USA surged after 1990 up to approx 24 units in 2020, and will be about 29 units in 2030 besides natural after some oscillation maximize and stable proportion can be witnessed in upcoming years.
Moreover, the analysis of petrol and oil started from 25 unit in 1980 and public of the USA will continue to use this fuel in 2030, which drastically gained its proportion according to that report.
Furthermore, in terms of wind power and Nuclear and hydropower relatively 5%, 6% and 4% respectively predicted in future.
