Net U.S. energy imports declined last year to their lowest level in more than 20 years, according to data from the U.S. Energy Information Administration.

Overall, net energy imports decreased by 19 percent from 2012 to 2013. Energy imports dropped while energy exports increased slightly. Growth in oil and natural gas production replaced imports and supported increased petroleum product exports, driving the decline in imports.
