Our economy runs on oil. Most of the tractors used for growing food run on oil. Nearly all of today’s cars and trucks run on oil. It is popular to talk about changing to some other fuel, but the practicalities are that any such change will be very slow. There is a huge cost associated with replacing cars and trucks with vehicles using other fuels, assuming we could figure out the technology to do this.
Since 2005, world crude oil supply has bumped up against what seems to be a limit of 75 million barrels of oil a day. No matter how hard companies try to extract more crude oil, and no matter how high world oil prices rise, they seem unable to extract more than 75 million barrels a day (MBD).
