IS INTENDED as a non-technical examination of a basic question: <b><i>Can any
combination of known energy sources successfully supply society’s energy
needs at least up to the year 2100?</i></b> In the end, we are left with the
disturbing conclusion that all known energy sources are subject to strict
limits of one kind or another. Conventional energy sources such as oil, gas,
coal, and nuclear are either at or nearing the limits of their ability to grow
in annual supply, and will dwindle as the decades proceed—but in any case
they are unacceptably hazardous to the environment. And contrary to the hopes
of many, there is no clear practical scenario by which we can replace the energy
from today’s conventional sources with sufficient energy from <i>alternative</i>
sources to sustain industrial society at its present scale of operations. To
achieve such a transition would require (1) a vast financial investment beyond
society’s practical abilities, (2) a very long time—too long in
practical terms—for build-out, and (3) significant sacrifices in terms of
energy quality and reliability.<o:p></o:p></span></p>
