Here is another thought that no one has talked about. Refineries. US refineries are mostly set up to refine heavy crude oil. Which comes from the middle east, South America, Canada. Crude oil pumped from US wells is light, sweet crude oil. We export our own crude oil because for the most part, we don't have the refineries to process it. We import all kinds of heavy crude oil because that is the type of oil our refineries can refine. You would think we would build our own refineries to refine our own crude oil. We don't. And it has been years since any new refineries have been built. It's time to refine our own oil and be truly energy independent.
