Americans are spending a dollar more for a gallon of gasoline than they were a year ago. Natural gas prices have shot up more than 150 percent over the same time, threatening to raise prices of food, chemicals, plastic goods and heat this winter.

The energy system is suddenly in crisis around the world as the cost of oil, natural gas and coal has climbed rapidly in recent months. In China, Britain and elsewhere, fuel shortages and panic buying have led to blackouts and long lines at filling stations.

The situation in the United States is not quite as dire, but oil and gasoline prices are high enough that President Biden has been calling on foreign producers to crank up supply. He is doing so as he simultaneously pushes Congress to address climate change by moving the country away from fossil fuels toward renewable energy and electric cars.

U.S. energy executives and the Wall Street bankers and investors who finance them are not doing anything to bolster production to levels that could bring down prices. The main U.S. oil price jumped nearly 3 percent on Monday, to about $78 a barrel, a seven-year high, after OPEC and its allies on Monday declined to significantly increase supply.
