How long, at the present rate of consumption, will current major energy reserves last, in the world and in the United States?
The best estimates indicate there will be enough oil to provide energy to the world for another 50 years. The current supply of natural gas, at gradually increased rates of consumption, will last almost 60 years. Coal supplies should last anywhere from a few hundred to one thousand years (only 2.5 percent of the world's coal has thus far been consumed).
Energy reserves in the United States are expected to last: 32.5 years for oil; 58.7 years for natural gas; and 226 years for coal. These estimates are based on 1986 production rates.
