why doesn't the US refinery capacity adapt to light sweet domestic oil in 2023?

ELI5 "Why does the US import so much oil when they are the world's largest exporter of it?"
It does use what it produces. It also exports what it produces. Whoever you heard that from either misunderstands the situation or is reliant on outdated information. The US has always imported a lot of crude oil to refine and export. Historically US refineries have had a lot of excess capacity which positioned it well to import crude and export refined products. This is a value-add industry since the refined products are more valuable than the crude. The US at one time consumed more crude oil than it produced. That has not been true over the last decade or two. The idea that the US consumes more oil than it produces is left over from the high oil prices and shortages due to the OPEC oil embargo in the 70's when that was true. US policy has focused on "energy independence" ever since. The US is huge. It doesn't make sense to ship oil from Alaska to the east coast to refine. As a result, the US tends to export crude from Alaska to Asia and imports crude from South America/Canada to the East coast. More on reddit.com

why are we still dependent on foreign imports that are heavier when we can be more energy independent? Can the federal government subsidize retrofitting or building new refineries that can take in more light sweet US cude?
