Thanks to Covid-induced supply chain issues and Russia’s war with Ukraine, oil prices have jumped to over $100/barrel. That and the dearth of refining capacity(converting crude oil to gasoline/diesel) has pushed the price of gasoline and diesel to record highs. One way to combat these prices is conservation — the less fuel we use, the less fuel we need to pay for, and if everyone uses less fuel then the price of oil will drop. Russia was supplying about 11% of the world’s oil and the lockdowns of 2020 due to Covid-reduced fossil fuel demand by about 20% which brought the price of oil to zero (for a short period). This demonstrates the principle of conservation crashing prices and defeating fuel price inflation.
