The Zero Emissions Vehicle Remains a Myth

The Zero Emissions Vehicle Remains a Myth:

Empty electric charging stationsAfter
the introduction of the mass-market hybrid
in the late 1990s,
mainstream America began a discussion about car exhaust that today
has evolved into an all-out quest for “zero emissions”
transportation. That pursuit is impossible.
As Bjorn Lomborg deftly explains in an op-ed for today’s
Wall Street Journal, even newfangled
electric cars leave a rather substantial carbon footprint
:

If a typical electric car is driven 50,000 miles over its
lifetime, the huge initial emissions from its manufacture means the
car will actually have put more carbon-dioxide in the atmosphere
than a similar-size gasoline-powered car driven the same number of
miles. Similarly, if the energy used to recharge the electric car
comes mostly from coal-fired power plants, it will be responsible
for the emission of almost 15 ounces of carbon-dioxide for every
one of the 50,000 miles it is driven—three ounces more than a
similar gas-powered car.

Not only that, but America’s electric grid may not be up to the
challenge of supporting just one electric plug-in vehicle per
family (and
most families own more than two cars
).
From Scientific American
:

Adding a plug-in car to the grid is equal to about a third of a
house, Kjaer said. And because early adopters are likely to spring
up in geographic concentrations, that could mean overloaded
transformers at the distribution level or plug-in cars potentially
causing power outages.

At least some of the trendier models will make you look good

when you stand next to them
in your driveway.
Even creative solutions like the electric Honda FCX Clarity (Top
Gear called it “the most important
car for 100 years
”), which uses a hydrogen fuel cell as a
power-source, has
its share of challenges
to go along with
its benefits
.
Just because you have water vapor coming out of your tailpipe—if
you even have a tailpipe—doesn’t mean that you have zero emissions.
It takes energy to create usable hydrogen or charge batteries, and
the bulk of our energy is still generated by fossil fuels which
create greenhouse gases. This means that discussions about which
vehicles produce more carbon dioxide on the road ignore a
big source of emissions.
In other words: pretty much all of these tax
incentives for hybrid and electric cars
are way too
generous.
