How about, for example, an early 1970's Caddilac getting 10 MPG? That's
5,000 gallons of gasoline, should any 1970's Caddilacs be able to run
another 50,000 miles.
5,000 gallons of gasoline is about 120 barrels. Crude has been around
$70 at some recent time or another, meaning energy cost of about $8,000.
Of course, cars with better efficiency than a 1974 DeVille will consume
less than $8,000 of energy (before fuel taxes) to drive 50,000 miles, but
still quite a few thousand dollars.
Do you really think that much is spent on energy to build a new car,
with so much of its cost to dealer going to wages and salaries and perks,
worker benefits, corporate taxes, liability insurance, advertising, etc.?
I hope this gives some idea on energy consumption by manufacturing.
Also consider the fact that older cars, even for a given amount of
energy consumption, produce plenty of pollution. Modern steel mills
and electric generating stations are comparatively clean, since it's
mainly internal combustion combustion engines that produce nitrogen oxides
and hydrocarbon vapors that are essential for the formation of the worst
air pollutant in densely populated areas - lower atmospheric ozone.
