The US will become energy self-sufficient in 2021. This is being brought about by an increase in supply as well as a reduction in demand. Tight oil and shale gas are increasing production. While the recent decrease in prices is reducing investment in the short-term, the long-term prospects are positive. The transport sector is becoming more efficient and domestically produced alternative fuels are backing out oil demand. Furthermore, the US will increase its exports of coal, especially from Gulf Coast ports. Cheap gas is also increasing its role in the US energy mix. By 2035 it will meet 35% of the US energy needs while it only meets 27% today.
