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.

該圖顯示了1980年至2012年美國的能源消耗以及2030年的預(yù)計消耗量。

在此期間，汽油和石油是主要的燃料來源，1980年使用了35萬億（35q）單位，2012年增加了42q。盡管最初出現(xiàn)了一些波動，但從1995年開始穩(wěn)步增長。預(yù)計這一趨勢將持續(xù)下去，到2030年將達到47季度。

在此期間，天然氣和煤炭的能源消耗量相似。從1980年的第20季度和第15季度開始，天然氣顯示出最初的失敗，而煤炭則逐漸增加，這兩種燃料在1985年和1990年之間相當。自1990年以來，消費一直在波動，但現(xiàn)在兩者都提供24個季度的服務(wù)。預(yù)計2030年煤炭產(chǎn)量將穩(wěn)步增長至31季度，而2014年后，天然氣產(chǎn)量將保持在25季度。

1980年，核能、水電和太陽能/風能的發(fā)電量僅為4季度。核能增加了3個季度，太陽能/風能增加了2個季度。在略有增長后，水電已回落至1980年的水平。預(yù)計到2030年，水電將保持這一水平，而其他水電將在2025年后略有增長。

總體而言，美國將繼續(xù)依賴化石燃料，而可持續(xù)能源和核能仍然相對微不足道。
