U.S. proven reserves (26.5 billion barrels of oil) divided by 365 days times U.S. daily consumption of oil (18.55 million barrels of oil) equals 3.9 years. The United States has less than four years of oil at present consumption rates.
Okay, we do continue to import more than a third of what we use, so that extends the 3.9 years out. Even better, we are currently consuming fewer barrels per day than we did in years past.
But our message continues: We need to make an Energy Shift! Away from fossil fuels, using conservation and renewables – via better products and practices!
