?在大多數(shù)情況下，美國(guó)的能源凈出口都發(fā)生在2050年的預(yù)測(cè)期——美國(guó)到2022年將成為一個(gè)能源凈出口國(guó)——強(qiáng)勁的國(guó)內(nèi)生產(chǎn)和相對(duì)平穩(wěn)的需求 ?提高能源效率抵消了能源需求的增長(zhǎng)——在參考案例中，能源消費(fèi)平均每年增長(zhǎng)0.4%——在參考案例中，到2050年，國(guó)內(nèi)生產(chǎn)總值預(yù)計(jì)平均每年增長(zhǎng)2.0% ?在2042年和2050年，美國(guó)的液體燃料和天然氣產(chǎn)量將繼續(xù)增長(zhǎng)——這是進(jìn)一步開(kāi)發(fā)頁(yè)巖資源的結(jié)果，盡管價(jià)格相對(duì)較低 ?2022年后，大多數(shù)新發(fā)電能力將是天然氣/可再生能源(參考案例)——這是天然氣價(jià)格低、可再生能源技術(shù)成本下降和扶持政策的結(jié)果

? U.S. net energy exports occur over the projection period to 2050 in most cases – U.S. becomes a net energy exporter by 2022 in Reference Case – Strong domestic production and relatively flat demand 

? Increased energy efficiency offsets growth in energy demand – Energy consumption grows about 0.4%/year on average in the Reference case – Gross Domestic Product is expected to average 2.0% annual growth to 2050 in the Reference case 

? U.S. liquids and natural gas production continues to grow through 2042 and 2050, respectively – Result of further tight and shale resources development, despite relatively low prices 

? Most new electricity generation capacity will be natural gas/renewables after 2022 (Reference case) – Result of low natural gas prices, declining renewables technology costs and supportive policies
