Total U.S. imports of energy as a share of energy consumption fell to their lowest level in 29 years for the first half of 2014, according to the U.S. Energy Information Administration (EIA).
Total energy use in the first six months of the year was 3 percent above consumption during the same time period in 2013, but consumption growth was outpaced by increases in total energy production, which led to a 17 percent reduction in net imports compared with the first half of 2013.
January and February accounted for 81 percent of the total increase in energy consumption, reflecting the effect of the polar vortex. Natural gas was more than half of the year-to-date increase, coal at just under a quarter, renewable energy for 12 percent, petroleum for 8 percent and nuclear for 3 percent.
