The graph illustrates to what extent the energy intake in US is expected to change between 1980 and 2030.
Overall, the figure for petrol and oil, coal and natural gas saw (is expected to see) considerable improvements, while nuclear and other sorts of energy units showed (likely to show) very little rise. Notably, the petrol and oil were (expected to be) the most popular energy resources.
In 1980, petrol and oil were the main sources of energy, positioning at 35 units. In the same period, coal and natural gas were in quite lower level of energy utilization, with the difference of 5 units, around 15 and 20 respectively. The nuclear, solar and hydropower were less used, with about 4 units each.
From 1980 to 2005, the indicator for petrol and oil slightly fluctuated, however from that period to 2030 it is expected to increase up to 50 units. Coal and natural gas from the beginning to around 2012 showed very minimal changes, being stuck between 15 and 20 quadrillions, and are projected to rise to roughly 25-28 units respectively. The rest 3 types of fuels almost did not change over the period and are more likely to go up just by 1 or 2 units each to 2030.
