The line graph below illustrates the U. S. energy consumption by fuel from 1980 to 2021 and projected until 2030.
Petrol and oil were consumed 35 quadrillion units in 1980. As the most consumed energies throughout the period, they had fluctuated between 1980 to 1995, rising dramatically to just below 45 quadrillion units in 2021. Their consumption is also estimated to reach the peak of 48 in 2030.
Natural gas, the second highly consumed fuel with 20 quadrillion units at the beginning of the period, experienced a fall to 17 until 1985, growing minimally to overtake that of coal at almost 23 in 1997. After falling to 23 in 2010, it rose slowly to reach 25 quadrillion units in 2015 and will have remained unchanged until 2030.
Coal, with consumption around 15 quadrillion units in 1980, saw an increase to overlap that of natural gas in 17 between 1985 and 1990 and then reached 23 in 1995. After being almost steady for about a decade, it overtook that of natural gas in 2005, being expected to grow gradually to the point 30 in 2030.
Nuclear and renewable energies were the least consumed fuels with about 4 quadrillion units in 1980. Nuclear and solar/ wind energies have grown up minimally in the whole period, being estimated to reach the point 8 and 5 in 2030, respectively. Also hydropower energy had fluctuated between 1995 and 2010, and it will remain almost unchanged at 4 quadrillion units until the end.
Overall it is clear that the consumption of the non-renewable energy resources has witnessed an increase in a 50-year period, while that of renewable energy resources has been almost unchanged.
