A major reason gasoline, diesel and natural gas prices are spiking is the push to export more fossil fuels from the USA by the oil/gas industry. This was facilitated by the 2015 decision to eliminate the ban on crude oil exports, which Obama/Biden and Republicans backed. It's simple supply and demand: reduce domestic supply by increasing exports to jack up domestic prices and increase profits. Around the same time at least one major domestic refinery was also closed, adding to the domestic supply restriction.
There is some effort to get the ban re-instated as of 2021:
> "Khanna drafted a letter to the White House Monday signed by nine Democrats urging the administration to block the export of U.S. oil, which has been allowed since 2015 when Congress lifted a 40-year-old ban on the practice. Since then, U.S. exports have regularly surpassed 3 million barrels a day, more than the production of major OPEC members such as Kuwait and Iran."
