“I take this opportunity to express my opinion in the strongest terms, that the amazing exhibition of oil which has characterized the last twenty, and will probably characterize the next ten or twenty years, is nevertheless, not only geologically but historically, a temporary and vanishing phenomenon – one which young men will live to see come to its natural end” (1886, J.P. Lesley, state geologist of Pennsylvania).
“There is little or no chance for more oil in California” (1886, U.S. Geological Survey).
“There is little or no chance for more oil in Kansas and Texas” (1891, U.S. Geological Survey).
“Total future production limit of 5.7 billion barrels of oil, perhaps a ten-year supply” (1914, U.S. Bureau of Mines).
“Reserves to last only thirteen years” (1939, Department of the Interior).
“Reserves to last thirteen years” (1951, Department of the Interior, Oil and Gas Division).
“We could use up all of the proven reserves of oil in the entire world by the end of the next decade” (President Jimmy Carter speaking in 1978 to the entire world).
“At the present rate of use, it is estimated that coal reserves will last 200 more years. Petroleum may run out in 20 to 30 years, and natural gas may last only another 70 years” (Ralph M. Feather, Merrill textbook Science Connections Annotated Teacher’s Version, 1990, p. 493).
“At the current rate of consumption, some scientists estimate that the world’s known supplies of oil … will be used up within your lifetime” (1993, The United States and its People).
“The supply of fossil fuels is being used up at an alarming rate. Governments must help save our fossil fuel supply by passing laws limiting their use” (Merrill/Glenco textbook, Biology, An Everyday Experience, 1992).
