There has been a lot of spirited debate about
the environmental impacts of electric cars lately, partly fueled by recent
studies such as the 500-page "Hidden Costs of Energy" report
by the National Academy of Sciences.
The Real Costs of Electric Vehicles
The Academy studied factors that are often overlooked by advocates of electric
cars. For instance, the energy required to assemble the car is generated by
fossil fuels. The manufacture, recycling and transportation of batteries are
costs that frequently aren't included in discussions about transportation
alternatives. Many components in electric-powered vehicles share the
environmental hazards of solar power and other semiconductor-based technologies
like cell phones, which require toxic chemicals in their production, adding
energy costs to handle the waste products, fuel to transport them, and energy
for destruction or processing. In fairness, modern gasoline- and diesel-powered
vehicles share many of these same costs. Though assembly is less costly in
terms of energy, the costs for production of parts are comparable in both
cases.
In terms of overall consumption of fossil fuels and the impact of that use on
the environment, the Academy concludes that at the present time, the "greenest" car is
a small, well-built, fuel-efficient gasoline car such as a Ford Focus. This has
set off a firestorm in policy circles, among advocates either for or against an
emphasis on electric-powered vehicles at the governmental level. At this point
in time, governments are favoring electric vehicles over conventional vehicles
with tax credits, vouchers and subsidy payments, all designed to encourage the
motoring public to choose electric. Klosters, the largest Ford dealer in
Australia, has reported a strong preference by customers for the Focus and
other very small gasoline and diesel cars over the electric cars, but also that
electric fleet sales have been improving.
There Has to Be Another Way
In all of this discussion, there is rarely any mention of additional
alternatives based on a traditional personal transportation model. Yet other
alternatives do exist. One possible solution for many is the use of an older
model of car, such as those favored by collectors and car enthusiasts. With the
addition of modern computer-controlled ignition systems and multi-point fuel
injection, an average car from the late 1950s on up can deliver amazing
performance and fuel-efficiency gains. It's possible to get nearly 30 miles per
gallon from virtually any American small-block V-8. New engines designed from
the ground up for the modern market are available from every manufacturer, and
can double or even triple the mileage on these older cars. Combine an updated
engine like this with the modern crop of computer-controlled six-speed
transmissions, and that muscle car of yesteryear can be as pleasant to drive
and as affordable to own as any modern car.
There are other advantages to this approach that make sense for the
environment. Certain costs can't be ignored in the equation, like the costs for
maintenance, including the costs in fossil fuel to manufacture parts. There is
also the fact that even with improvements that bring an older engine up to
modern standards, the fuel mileage will still be less than what is achievable
with a small car powered by a small engine. The fuel costs for an electric car
are generally agreed to be less, but it should be remembered that electricity
costs from utilities reflect governmental subsidies and credits and don't
generally reflect the actual cost to generate and deliver that electricity. The
Academy also raised the possibility that a large increase in "plug-in"
electrics and hybrids would raise the demand for power generation to support
them. That would require building additional power plants, of which many would
be powered by fossil fuels. Until this cost is accounted for, large-scale
movement to electric-powered vehicles is economically not feasible in the
opinion of many.
Historic Vehicles Offer a Unique Benefit
However, there is one benefit offered by updating an older car, a benefit that
applies equally as well to an unmodified older car, that is not offered by any
modern car, regardless of whether it is powered by fossil fuels, electricity,
hydrogen or some hybrid of these sources. That benefit is that the car was
produced decades ago, and is still in service. Most vehicles manufactured from
the mid-1950s on are easily capable of handling traffic and highway speeds, as
long as they are in good, operable condition. Of course, most could use braking
or cooling upgrades to improve traffic safety and utility. What is the impact
of an older car on the discussion concerning the relative cost merits inherent
to different types of personal transportation?
Whether a new car is electric-powered, hybrid or burns fossil fuels, it has to
be manufactured before it can have any impact. The older car in serviceable
condition doesn't have this burden. In fact, when you take into account the
fact that the car is still perfectly suitable for personal transportation,
there is a strong argument that well-built vehicles of the past, meant to last
a lifetime, eliminate the need to buy another car for a considerable amount of
time. Considering the average trade-in cycle of two to three years, a 1966
Chevy Nova is a greener car than a brand new Chevy Volt, simply because it has
eliminated the need to manufacture over 20 cars in the time it has been in
service. Considering that the cost to manufacture a modern car is the largest
single component of its environmental and economic damages, this is not an
insignificant point.
The United States produced millions upon millions of well-built, long-lasting
vehicles from the postwar period right through the mid-1980s. There are still
millions of these vehicles in serviceable condition, and many more that can be
made serviceable with little expense. If you are a driving enthusiast, or a serious
advocate for lessening the use of fossil fuels, you should seriously be
considering an older car for your personal transportation, and encouraging
others to do the same. If you like your car and form a bond with it, you can
save the costs to the environment associated with manufacturing newer cars of
every type. This doesn't mean you need to forget owning a new car, simply that
you can mix in the use of your old car and rest easy in the knowledge that you
are exercising what is arguably the most environmentally favorable alternative
available for personal transportation in the current century.
