Everyone from the Republicans to Democrats to major environmental
groups are singing hosannas to biofuels and hybrid cars as the
salvation from peak oil and global warming. Will trusting corporations
to manufacture environmentally friendly cars make a dent in the world's
ecological crises? Or could the "solutions" actually be making the
problem worse?
The planned obsolescence and massive production of consumer objects in
the overdeveloped countries is responsible for catastrophic climate
change and species extinction. The question which we obviously need to
address is how to improve the quality of life while decreasing the
quantity of useless junk and not throwing anyone out of work. But
unflinching loyalty to a growth economy prevents corporate
environmentalists from searching for serious transportation options.
Cars are a huge problem, both for global warming and the exhaustion of
oil reserves. With less than 5% of the world's population, the US
produces 25% of carbon emissions. Transportation causes a quarter of
greenhouse gas emissions.
The wastefulness of the automobile is staggering. Roughly 10% of the
chemical energy of gasoline makes wheels turn around. Amory Lovins
computes that, with a 10% efficient car with a driver, passenger and
luggage weighing 300 pounds (which is about 10% of the car weight),
only 1% of the fuel's energy actually moves what needs to be moved.
There is an unending stream of stories in the corporate media that
biofuels and hybrid cars are the answer. Biofuels promise to reduce oil
use and decrease pollution by making fuel from corn and soy instead of
petroleum. By generating their own electricity, hybrid cars use less
gasoline and therefore emit fewer greenhouse gases.
Techno-fantasies fixate on one portion of transportation: the use of
fuel to make a machine go. In reality, transportation is a system for
getting around. That system requires energy for manufacture and
disposal of machines, land use for moving and storing the things that
move, related impacts of moving machines, and an ideology that weaves
transportation into a society.
The horror of the car
Let's look at seven dimensions of the destructiveness of gasoline-powered cars.
1. Manufacture. According to Richard Heinberg, "more than half of the
energy consumption attributable to each vehicle on the road occurs in
the manufacturing process." Thus, unless an alternative approach to
transportation significantly reduces manufacturing, it is not even
addressing half the problem.
2. Operation. Driving cars results in huge releases of carbon dioxide,
the major greenhouse gas that causes global warming. Myopic views of
transportation can't see beyond the driving phase.
3. Disposal. Car batteries have one of the widest arrays of toxic
chemicals short of a nuclear dump. Their poisoning of countless
generations is virtually ignored by automobile apologists.
4. Land use for roads. Roads break up neighborhoods, farms and animal
habitat and contribute directly to global warming. Paved surfaces
convert sunlight to heat and do not convert sunlight to photosynthesis
as do the plants they eliminate.
5. Land use for storage. What could be uglier and ruin more urban areas
than parking lots? Vast expanses of parking lots contribute to "urban
warming," which makes cities warmer than the surrounding countryside.
The problem is not just parking lots at shopping centers, work, school,
church, hospitals and sporting events - we have our own little parking
lots at home. Most likely, driveways for home garages average even
higher ratios of access-to-destination paving than do business parking
lots. The millions of little driveways to home parking garages comprise
an extremely inefficient use of land and probably contribute to urban
warming.
6. Other effects. Negative effects from cars which are even less likely
to make it into official equations include horrible pollution from
burning off ("flaring") unwanted gas from pipelines in Nigeria and
elsewhere and over a million animals a year killed on US highways
annually. Health effects from toxic automobile emissions could fill
many volumes (and probably have).
7. Ideology of idolatry. I remember going to church as a kid and
hearing the preacher say that "idolatry" is not limited to worshipping
a little carved figure but is any groveling after material possessions.
US society has no idol as perverse, as pervasive and as evil as the
automobile. The car is the apex and the focus of the ideology that the
accumulation of objects is the source of all happiness. This
accumulation of objects is killing Life on Earth. Any proposed energy
plan that leaves the car unchallenged is a plan to increase the
destruction of life and is not a plan to preserve it.
Biofuels, hybrids and motorcycles
Biofuels such as ethnol from corn and biodiesel from soy are often
touted as the world's great salvation from the scarcity of oil and its
polluting consequences. Biofuels do neither and introduce problems even
worse than oil. Brian Tokar's summary documents that "every domestic
biofuel source produces less energy than is consumed in growing and
processing the crops." The small reductions in greenhouse gases from
burning biofuels are outweighed by their environmental damage of
increased deforestation, pesticide usage, nitrate runoff, and water
depletion.
Biofuels do nothing to lessen the energy used for manufacturing or
disposing of cars or lessen land usage for driving and parking cars.
But biofuels require massive land use for growing crops, which means
less food for people as there is more food for cars. Widespread use of
biofuels would massively increase world hunger and transform wars for
oil to wars for land to grow biofuel crops.
Hybrid cars, on the other hand, offer real advantages by combining the
use of electricity with gasoline. According to Consumer Reports, "All
hybrids save fuel by using an integrated starter motor. It
automatically shuts off the gasoline engine when the vehicle comes to a
stop, such as at a stop sign or traffic light. The engine automatically
starts again when needed." This results in fewer carbon dioxide
emissions from the use of less gasoline.
The advantage of hybrids is not as much as their enthusiasts might have
us believe. The Consumer Reports rating for overall fuel economy of
Toyota's Prius is 44 mpg (not 50 to 60 mpg). This is better than 34 mph
for the Volkswagon Jetta TDI, but hardly a night and day difference.
Since hybrids average $3000 more than comparable cars, it is reasonable
to ask if they require more energy to manufacture. Maybe not, because
the $3000 could include initial costs for research and development. But
a much higher cost to manufacture could be hidden by government
subsidies to help hybrids gain a share of the market. There is a real
possibility that hybrids transfer energy from the driving portion of
their use-cycle to the manufacturing phase.
There is no reason to believe that hybrids offer any advantage over
conventional cars in terms of energy used for disposal, land used for
roads or parking lots or road kill. The amount of fuel needed for
driving is a real issue and no one doubts hybrids excel in this area.
The hybrid with the best fuel economy is the Honda Insight, which
Consumer Reports rates at 51 mpg. To get this fuel savings, the Insight
is a two-seater.
This leads to the question: If the greatest fuel saving in a hybrid
comes from reducing the number of passengers, why not reduce it again
from 2 to 1 and ride a motorcycle? Are there advantages of hybrids that
have not been available for decades via motorcycles?
There is good reason for suspecting that motorcycles might have less
total negative effect than hybrids. Being smaller, they certainly
require less energy for manufacture and disposal than any car. Though
they require road space, a "motorcycle lane" would be more enforceable
and more narrow than a "carpool lane." Parking 1000 motorcycles would
certainly require less space than parking 1000 cars.
Despite their popularity among some environmentalists, both biofuels
and hybrids leave the consumerist mentality untouched. They both create
an obscenely false sense of security, much like advising someone to put
a band-aid on an arterial wound.
If hybrids were promoted as part of a larger plan to reduce automobile
production by 95% and require that those few cars that are manufactured
be hybrids (or get equivalent gas mileage), we could be far more
enthusiastic about them. I don't think that's what Toyota and Honda
have in mind. At least Philip-Morris pretends to believe that smoking
is bad. The current fad for hybrids has more in common with a campaign
to improve health by smoking low tar and nicotine cigarettes than it
does with confronting the need to quit the addiction.
Sharing transportation
Shared rides and mass transit involve collective solutions rather than
individual life style changes. There is so much hype that people should
make the moral decision to car pool that it is easy to overlook the
fact that ride sharing is a collective rather than an individual
approach.
Car pooling, even with designated lanes, will have minimal
environmental effects if the same number of people own cars and simply
rotate whose turn it is to drive. Though it does reduce the number of
cars on the road, it has no effect on the energy to manufacture cars
and little, if any, effect on car ideology.
Hitchhiking is car pooling with a new friend. Since those who hitchhike
are less likely to own cars, the practice helps combat the ideology of
consumerism. Perhaps the greatest barrier to hitchhiking is that it can
land you in jail. For politicians who whine that environmentally
friendly transportation is too expensive, a zero-cost option would be
repealing laws against hitchhiking. If corporate media had a genuine
concern with global warming, they would suspend car ads and replace
them with messages encouraging drivers to pick up hitchhikers.
Motor pooling goes beyond car pooling because it involves an
intentional reduction in the number of cars. Many state agencies and
businesses have cars that employees can reserve for job-related travel.
One of the most practical ways to decrease cars would be for housing
cooperatives or co-housing groups to have a certain number of cars for
every 100 families. People could use mass transit, bicycles or walking
for the vast majority of their travel. They would reserve a car only
for trips where mass transit was unlikely or they had things to haul.
Mass transit must exist for motor pooling to effectively reduce the
number of cars.
Mass transit is often promoted as one of the best options for energy
reduction. The recognition is well-deserved. Nevertheless, there is a
downside to mass transit: a lightly loaded bus or train will use more
energy per passenger than a car.
Auto companies have done their best to push car addiction and undermine
mass transit. In the 1940s auto companies bought up several urban rail
systems and ran them into the ground. Many US bus systems are so awful
that it takes over two hours for what would be less than a 30 minute
car ride. This includes long waits in weather that is often cold or wet.
Biofuels and hybrids actively undermine development of environmentally
friendly mass transit in two ways. To be effective, mass transit must
have a large number of users. Promotion of individual modes of
transportation lowers the average occupancy on buses and trains. In
addition, low costs for mass transit are based on people living in
close proximity. Since biofuels and hybrids fail to reduce land use for
parking lots, they help spread out space needed for living and working,
thereby working against the high density that mass transit depends on.
However, shared rides and mass transit are not positive across the
board. Though definitely less damaging than gasoline-powered cars,
buses and trains require energy to manufacture and energy for disposal.
Mass transit requires less land use for operation and vastly less land
use for storage.
Human-powered transportation
Not much fossil fuel is needed for cycling and walking. This is far
from their only advantage. Energy required to manufacture and dispose
of bikes is tiny compared to autos and mass transit. Manufacturing to
prepare for walking includes an extra winter coat and a hat for a sunny
day.
Land use for biking and walking paths is minuscule in comparison to
roads for cars. Bikes require a little storage space and walking, none.
For every machine mode of transportation, usage involves road kill and
the release of toxins which make the "other effects" a negative. For
cycling and walking, the "other effects" take on a positive value. They
are the only forms of transportation where people actually receive
health benefits from moving from place to place. With our country
suffering epidemics of obesity, diabetes and heart disease, it is
unpatriotic to oppose tearing up roads and replacing them with walking
paths.
The way we move about is not an isolated issue unrelated to other areas
of our lives. Types of transportation we utilize affect other modes of
transportation and how our communities are structured. Bicycling and
walking can only become major ways to get around if our homes are
located near work, schools, churches and recreation. They lead us to
ask, "Do we want mega-grocery stores, WalMarts, Home Depots and
shopping malls, or do we want small businesses that we can get to
without a traffic jam?"
The most valuable part of person-powered transportation is that it
encourages a collective reassessment of how we want to organize
society. We need to decide together how we want to construct urban
space so that people can readily get to where they need to go without
contaminating their community.
Deep green vs. shallow green
It cannot be stated too often that the value of biking and walking is
not limited to saving the fuel from driving a machine. It includes
savings from the fuel used to build and dismantle the machine, land
usage and storage, bodily movement instead of breathing poisons while
watching animals die, and the creation of communities which share
resources instead of mindlessly consuming.
There is a sharp divide between a "deep green" look at the social
nature of ecological problems and the "shallow green" approach of
corporate environmentalism. Deep greens emphasize that America can
improve its health and quality of life while manufacturing fewer
objects and shortening the work week. Shallow greens are loathe to say
anything about the need to produce less and flee from addressing moral
and political dilemmas of a growth economy.
Shallow greens often accuse deeps of being uncompromising and refusing
to accept small steps in the right direction. Mass transit shows the
opposite to be true. While mass transit has negative aspects, it is a
step in the right direction because it reduces the number of cars.
But mass transit needs population density and high use to be effective.
Preserving cars via biofuels and hybrids requires using land space for
driving and parking, thereby lowering population density. They
encourage people to drive cars instead of ride trains. In both ways,
the shallow green approach undermines mass transit. Chasing after
techno-fixes to a social problem is not a small step in the right
direction - it is a blind step in the wrong direction.
Spiritual afterthought
As Moses smashed the 10 Commandments on the golden calf and climbed the
mountain for a back-up copy, little did he know that he would return to
find those who worshipped a silver calf. For they imagined that
substituting silver for gold would mean their behavior was no longer
idolatrous. Those who worshipped the silver calf begat followers, who
begat more followers, and so on, until they begat those who use
biofuels and drive hybrid cars with silver calves as hood ornaments.
And they imagine that adorning the hood of their Prius with a silver
calf means that it is no longer an idol.
