Here's another doomsayer:
$this->bbcode_second_pass_quote('', 'C')urrent estimates of fossil fuel reserves vary to an astonishing degree. In part this is because the
results differ greatly if cost of extraction is disregarded or if in calculating how long reserves will last,
population growth is not taken into consideration; or, equally important, not enough weight is given to
increased fuel consumption required to process inferior or substitute metals. We are rapidly approaching
the time when exhaustion of better grade metals will force us to turn to poorer grades requiring in most
cases greater expenditure of energy per unit of metal.
But the most significant distinction between optimistic and pessimistic fuel reserve statistics is that
the optimists generally speak of the immediate future - the next twenty-five years or so - while the
pessimists think in terms of a century from now. A century or even two is a short span in the history of a
great people. It seems sensible to me to take a long view, even if this involves facing unpleasant facts.
For it is an unpleasant fact that according to our best estimates, total fossil fuel reserves recoverable
at not over twice today's unit cost, are likely to run out at some time between the years 2000 and 2050, if
present standards of living and population growth rates are taken into account. Oil and natural gas will
disappear first, coal last. There will be coal left in the earth, of course. But it will be so difficult to mine
that energy costs would rise to economically intolerable heights, so that it would then become necessary
either to discover new energy sources or to lower standards of living drastically.
For more than one hundred years we have stoked ever growing numbers of machines with coal; for
fifty years we have pumped gas and oil into our factories, cars, trucks, tractors, ships, planes, and homes
without giving a thought to the future. Occasionally the voice of a Cassandra has been raised only to be
quickly silenced when a lucky discovery revised estimates of our oil reserves upward, or a new coalfield
was found in some remote spot. Fewer such lucky discoveries can be expected in the future, especially in
industrialized countries where extensive mapping of resources has been done. Yet the popularizers of
scientific news would have us believe that there is no cause for anxiety, that reserves will last thousands
of years, and that before they run out science will have produced miracles. Our past history and security
have given us the sentimental belief that the things we fear will never really happen - that everything turns
out right in the end. But, prudent men will reject these tranquilizers and prefer to face the facts so that
they can plan intelligently for the needs of their posterity.
Looking into the future, from the mid-20th Century, we cannot feel overly confident that present
high standards of living will of a certainty continue through the next century and beyond. Fossil fuel
costs will soon definitely begin to rise as the best and most accessible reserves are exhausted, and more
effort will be required to obtain the same energy from remaining reserves. It is likely also that liquid fuel
synthesized from coal will be more expensive. Can we feel certain that when economically recoverable
fossil fuels are gone science will have learned how to maintain a high standard of living on renewable
energy sources?
Anybody tell me who wrote this and when?
