Okay! There’s a lot of data in this question. Let me simplify the things and instead of writing an answer I’ll propose the points to be mentioned. Please write your answer and share it with me through the comments box.
Petrol and oil: 35 quadrillion unites energy consumed in 1980, fluctuated will 1995 and increased steadily thereafter. Energy consumption is projected to reach about 50 quadrillion units in 2030. The largest source of energy consumption both in the past as well as future.
Natural Gas: Energy utilization was 20 quadrillion unites in 1980. Fluctuated till 2010 and is expected to stay constant in the future at about 25 quadrillion units.
Coal: Energy consumption has increased steadily since 1980 and is expected to reach 30 quadrillion units in 2030 becoming the second largest source of energy.
Nuclear, Solar/ Wind, Hydropower: Energy consumption was almost similar for these three sources in 1980. Energy utilization has increased marginally since then. While energy use from solar and wind power has stayed at the same level and is estimated to rise insignificantly in the future. Energy consumption from hydropower has fluctuated and is expected to fall slightly by 2030. It is expected to contribute the least to the energy usage in the U.S by 2030.
Marginally = insignificantly; slightly.
Consumption = use; usage; utilization.
