However, under current rules, oil can only be pumped from the reserve at a maximum rate of “4.4 million barrels per day for up to 90 days,” according to the Department of Energy. Student loan ...
Consuming less or importing more oil prolongs the useful life of existing oil reserves. Between 1970 and 2007, due to declining production and increasing demand, net US imports of oil and petroleum products increased from 3.16 million barrels per day (502 × 10 ^ 3 m 3 /d) in 1970 to 12.04 million barrels per day (1.914 × 10 ^ 6 m 3 /d) in ...
