You are right. In the last 2 years two refineries have been shut down within 50 miles of New Orleans. While in the middle of a expansion, Shell oil shut down all operations.Not only have no new refineries been built, but the oil companies have also shut down refineries in the US during the same period of time. In addition, during the pandemic, they cut refinery production to match lower demand and have yet to increase production back to pre-pandemic levels. The oil companies are making record profits now on lower production, so why would they change?
