Нефть: откуда и куда

The U.S. population is now 311.6 million or roughly 4.5% of the world’s population (6.9 billion). Oil producing nations produce 85.4 million barrels of crude oil per day. The world presently consumes 85.8 million barrels per day. There is a shortage of 400,000 barrels of oil per day.

If every nation in the world was consuming oil at the same rate, then the U.S. should be consuming 3,856,614 barrels per day (calculated by multipying the total world’s oil consumption of 85.8 million barrels by 4.5%). However, in actuality the U.S. actually consumes 19.5 million barrels of oil per day, or roughly 23% of total world oil consumption. 71% of the oil consumed by Americans is used for transportation—just for getting around or transporting things in our cars, trucks, buses, trains, ships and planes.

The U.S. produces only 10% of the world’s oil, yet we consume 23% of the world’s oil, so it is necessary for us to import the other 13%, or roughly 11,154,000 barrels per day, from outside the country At the end of 2010, the price per barrel of crude oil was about $90. The U.S. paid $400 billion for its imported oil.

Passenger cars use more than 40 percent of the oil consumed in America today. That’s roughly 7.8 million barrels of oil per day or 2.881 billion barrels of oil per year. Drivers spent $186 billion on gas fuel in 2010. Without vehicle fuel economy improvements, Americans will spend an estimated $260 billion in 2020 on gasoline.

If we replaced just 10% or 25.4 million of our passenger vehicles with hybrids and electric vehicles or converted those vehicles so they could run on natural gas (a fuel we have in abundance, and sufficient enough to last os 100-200 years), reduced highway speed limits to 55 mph, improved gas mileage per gallon only 3-mpg, and drivers took public transportation or mass transit, we could reduce imported oil by approximately $40-45 billion per year (assuming a price of $90 per barrel of oil).
