By law we don't export our oil or natural gas, though there are many who wish to change that so as to take advantage of higher world energy prices. (some minor exceptions)
We do export a significant amount of refined products due to excess refining capacity

We are extracting/depleting our oil and gas reserves as fast as we can. Kind of like shoving the throttles up when low on fuel so as to get to the airport before one runs out...same logic/thought(less) process at work
