The graph illustrates how much energy had been consumed in America from 1980 to 2008 along with expectations until 2030.
Generally, the trends of using various energy resources were upward. However, eco-friendly powers seemed to be not widely used throughout the course of time and that was a far cry from the fossil fuels energy.
In 1980, petrolium and oil consumption started at large quantities (35 quadrillion units) which nearly doubled that of coal and natural gas (16 and 20 quadrillion units respectively) and were approximately seven times as much as the use of eco-friendly and nuclear energy, i.e 4 quadrillion units. Moreover, the amount of eco-friendly powers appeared to fluctuate slightly and stagnated from the beginning in 2008 (close to 4 quadrillion units). Meanwhile, mineral energy experienced periods of fluctuations but the trends were all upward until 2008, namely 28 quadrillion units in coal and 40 quadrillion units in petrolium.
In 2030, it is noticeable that oil and coal energy are anticipated to be consumed at increasing rates and reach 48 and 30 quadrillion units , respectively. On the contrary, the expectation for the rest of the energy resources is that they will remain stable, rise and fall no more than 0.1 quadrillion units until 2030. Nevertheless, solar, wind and nuclear powers are estimated to begin a linear growth from 2025 (5 quadrillion units)
