Energy Conservation
Periodic international events remind us of the vital role of energy in
the economic well-being of developed countries. The ability of common
folk in the industrial nations to live more opulent lives than the kings
and queens of yesteryear is directly related to the energy servant.
Transportation, communication, agriculture, housing, manufacturing,
health care services, and the like are all facilitated by the readily
available supplies of energy, both fuel and power.
At the same time, there are recognizable limits to available energy
sources. Despite new discoveries, coal, oil, gas, and other fossil or or-
ganic fuels can be estimated in total volume, with less this year than
there was last. There is a finite limit to the potential development of
renewable energies, all derived from the sun, such as wood, wind, hy-
dropower, etc. In terms of magnitude, nuclear power (the fusion con-
cept, at that) is the only known energy source that offers hope of being
able to industrialize the third world and to sustain a growing world
population over centuries rather than decades. Yet the use of nuclear
power is mired in political quicksand in the United States.
The conclusion for the designer of HVAC systems, all of which by
definition are energy-managing and energy-consuming, is that there
