The given line graph illustrates data from a report in 2008 regarding energy consumption in the USA since 1980 with predictions until 2030.
Overall, fossil fuels have shown increases in consumption since the start of the period, with expectations for even more reliance on these fuel sources. Cleaner energy sources have accounted for considerably less consumption with predictions for a similar trend.
Regarding fossil fuels such as coal, natural gas, petrol and oil, they have seen steady increases in energy consumption since 1980. Petrol and oil started at 35 quadrillion units in 1980, then fluctuated until 2000, at which point they rose steadily with a prediction of over 45 quadrillion units by 2030. Additionally, coal followed a similar rising trend. It is predicted that it will have surpassed 30 quadrillion units by 2030. Natural gas usage demonstrated fluctuations and it is set to level off at around 24 quadrillion units from 2020 onwards.
In contrast, cleaner energy fuel sources all began the period at under 5 quadrillion units and showed declines in their use, with the exception of nuclear, which climbed slightly to 6 quadrillion units in 2005 with solar/wind expecting to see slight increases. Hydropower is projected to remain relatively unchanged until 2030.
