Q32:
Delta products, Inc., has recently switched at least partly from older technologies
using fossil fuels to new technologies powered by electricity. The question has been
raised whether it can be concluded that for a given level of output, Delta’s operation now
causes less fossil fuel to be consumed than it did formerly. The answer, clearly, is yes,
since the amount of fossil fuel used to generate the electricity needed to power the
new technologies is less than the amount needed to power the older technologies,
provided that the level of output is held constant.
