The line graph illustrates the consumption of different energy sources in the USA from 1980 to 2008 and includes projections until 2030. The energy sources presented are petrol and oil, coal, natural gas, nuclear, solar/wind, and hydropower, measured in quadrillion units (QU).
Overview: Overall, petrol and oil have consistently been the dominant energy source throughout the period and are projected to remain so in the future. Coal and natural gas also show significant consumption levels, with coal expected to rise sharply. In contrast, renewable energy sources such as nuclear, solar/wind, and hydropower have had much lower usage and are projected to grow more slowly.
Body Paragraph 1: From 1980 to 2008, petrol and oil consumption remained the highest, starting at around 35 QU in 1980, rising steadily to about 40 QU by 2008. Projections suggest this trend will continue, with consumption reaching approximately 50 QU by 2030. Coal usage also experienced growth, increasing from 15 QU in 1980 to 23 QU in 2008, and is forecasted to rise sharply, peaking at around 30 QU by 2030. Similarly, natural gas consumption fluctuated between 15 and 20 QU during the observed period but is expected to stabilize at around 25 QU after 2020.
Body Paragraph 2: Renewable energy sources such as nuclear, solar/wind, and hydropower have consistently had much lower consumption rates. Nuclear power usage grew slowly, from 5 QU in 1980 to around 8 QU in 2008, and is projected to increase slightly to about 10 QU by 2030. Solar and wind energy saw minimal growth, starting below 2 QU in 1980 and expected to reach just under 5 QU by 2030. Hydropower remained relatively stable throughout the period, hovering around 5 QU, but it is expected to remain flat, with no significant change in the coming years.
