When America starts producing our own oil/gas again and quit having to import it. We were producing so much product not that long ago that we were exporting it to other countries. Now we import again and are at the mercy of foreign governments.
Many producers cut back on production when the price per barrel dropped to $40 or less. Cutting back on production meant laying off workers, etc. it takes time to get things rolling again and since the price has increased productivity has increased albeit slowly. And it can’t keep up with the increased demand.
And we imported crude while exporting petroleum products because it’s a global trading market. Canada is our largest source of imported crude.
