KTRH News reported on a rally at Houston City Hall to "Restore Energy Independence," but experts say that's much easier said than done.
"If we would reduce the importation of crude oil from foreign suppliers, not counting Canada, that would of course increase the price of gasoline for consumers," says Hirs.
"It would also entice the U.S. oil industry to find more domestic supplies."
But no president since Carter has attempted it.
"The one thing that throws elected officials out is if the price goes up at the pump, or if the price goes up at the electricity meter."
Even when the U.S. was a net exporter under Trump, Hirs says we were still importing different grades of crude to meet our refining needs.
"It's going to take a large investment for us to be completely independent from foreign markets on crude oil. I don't think it's going to happen in the next 20 to 30 years."
