The graph shows energy consumption in the US from 1980 to 2012, and projected consumption to 2030.??????

Petrol and oil are the dominant fuel sources throughout this period, with 35 quadrillion (35q) units used in 1980, rising 42q in 2012. Despite some initial fluctuation, from 1995 there was a steady increase. This is expected to continue, reaching 47q in 2030.

Consumption of energy derived from natural gas and coal is similar over the period. From 20q and 15q respectively in 1980, gas showed an initial fail and coal a gradual increase, with the two fuels equal between 1985 and 1990. Consumption has fluctuated since 1990 but both now provide 24q. Coal is predicted to increase steadily to 31q in 2030, whereas after 2014, gas will remain stable at 25q.

1n 1980, energy from nuclear, hydro- and solar/wind power was equal at only 4q. Nuclear has risen by 3q, and solar/wind by 2. After slight increases, hydropower has fallen back to the 1980 figure. It is expected to maintain this level until 2030, while the others should rise slightly after 2025.

Overall, the US will continue to rely on fossil fuels, with sustainable and nuclear energy sources remaining relatively insignificant.

该图显示了1980年至2012年美国的能源消耗以及2030年的预计消耗量。

在此期间，汽油和石油是主要的燃料来源，1980年使用了35万亿（35q）单位，2012年增加了42q。尽管最初出现了一些波动，但从1995年开始稳步增长。预计这一趋势将持续下去，到2030年将达到47季度。

在此期间，天然气和煤炭的能源消耗量相似。从1980年的第20季度和第15季度开始，天然气显示出最初的失败，而煤炭则逐渐增加，这两种燃料在1985年和1990年之间相当。自1990年以来，消费一直在波动，但现在两者都提供24个季度的服务。预计2030年煤炭产量将稳步增长至31季度，而2014年后，天然气产量将保持在25季度。

1980年，核能、水电和太阳能/风能的发电量仅为4季度。核能增加了3个季度，太阳能/风能增加了2个季度。在略有增长后，水电已回落至1980年的水平。预计到2030年，水电将保持这一水平，而其他水电将在2025年后略有增长。

总体而言，美国将继续依赖化石燃料，而可持续能源和核能仍然相对微不足道。
