The
Big Shift
A
great energy transition is coming. Will it mean a better day for
humanity, or turmoil? First in a series.

An
energy transition has begun, but it's probably not the one you
imagined.
It
might have an ugly financial face, an authoritarian political mask or
come in the guise of geographic disunion.
But
it probably won't look like a solar panel or a windmill. And it won't
include flying cars or undersea homes.
Although
no one really knows where the globe's energy mix is headed or how it
will shape our lives in the future, energy experts now offer a
diversity of forecasts, stories and warnings.
Their
pronouncements are both myth busting if not startling.
When
economies shrink
Jeff
Rubin, the former chief economist for CIBC, argues that "the new
green" will not be endless arrays of solar panels or windmills
but less oil and smaller economies.
Mikal
Hook, an analyst at Sweden's Uppsala Depletion Group, goes further
and argues that any orderly energy transition might now be impossible
because renewables simply can't grow as fast as oil.
He
also warns that all citizens should prepare for "high and likely
volatile oil prices," and that governments should be "educating
their citizenry of the risk of contraction to minimize potential
future social discord."
Chris
Turner, Calgary's sustainability journalist, believes that an orderly
energy leap can be made but political leaders and the status quo
aren't showing much interest in public transit or renewable forms of
energy at least in North America.
Joseph
Tainter, the U.S. anthropologist and historian, suggests that
civilization has climbed a tall spiral staircase of energy complexity
without knowing how far we can go with the resources we have at hand.
He
warns that it takes energy to solve complex problems and he doesn't
think society can voluntarily cut back on fossil fuels.
Vaclav
Smil, a University of Manitoba researcher and one of the world's
great energy analysts, believes that energy obesity is the moral
problem and proscribes a diet consisting of low-hanging fruit such as
efficient furnaces and high speed trains.
Douglas
Reynolds, an economist and engineer at University of Alaska
Fairbanks, calls the collapse of the Soviet Union a dark energy
transition and one completely unforetold.
When
oil production collapsed from 12 million to five million barrels a
day after 1989, the Berlin Wall fell, the rich got richer, the
Eastern Union dissolved and the Warsaw Pact crumbled.
And
that's just a sampling of the voices and ideas you'll read in this
series on energy transitions. In the next couple of weeks we'll take
a hard look at the myths, the facts and some enduring truths about
dirty oils, uncertain renewables and contracting economies.
Where
we are now
But
before we can talk about change, evolution, innovation or just plain
dissolution, we need to appreciate where we are in the energy world.
The
basic global energy picture is what Nobel laureate Richard Smalley
once called the "terawatt challenge." And it comes with no
comfortable answers.
What's
a terawatt? It is the average rate at which energy is released in the
burning of five billion barrels of oil during a year.
The
world uses on a continuing basis about 17 terawatts of energy in the
form of coal, gas, oil and nuclear power. Eighty-five per cent of
that work comes from fossil fuels. In fact, oil provides 37 per cent
of the energy mix and accounts for 90 per cent of all transportation
fuels. It's the lynchpin of the global energy system.
Renewable
or green forms of energy such as hydro and wood contribute slightly
more than one terawatt. Wind, solar and biofuels barely appear on the
chart. (One terawatt, by the way, is the amount of energy the world
consumed in 1890.)
Terrawatt
challenge: Chart shows where our energy comes from now. Where can we
go from here?
Now
the relationship between economic growth and energy consumption is
pretty direct, if not fundamental. Countries that spend lots of
energy, and particularly oil, tend to be wealthier than those that
don't.
"Just
as higher metabolic rates are required to sustain and grow larger,
more complex bodies, so higher rates of energy consumption are
required to sustain and grow larger, more developed economies that
provide greater levels of technological development and higher
standards of living," explains a group of scientists in the
journal BioScience in 2011. Even GDP is strongly linked to oil
spending.
In
an article entitled "Energetic Limits to Economic Growth"
the scientists add that a global energy diet would likely constrict
the economic system. "Gradually reducing an individual's food
supply leads initially to physiological adjustments, but then to
death from starvation, well before all food supplies have been
exhausted," say the scientists.
Changing
the diet
Now
everyone who buys gasoline knows that the era of cheap oil is over
and that is already feeling the pinch. Business as usual is not
working.
Difficult
hydrocarbons such as bitumen and deep sea oil are now replacing easy
oil, and that shift alone represents a dramatic and little heralded
energy transition.
The
carbon, capital and environmental footprint of these difficult or low
quality crudes are bigger and more complex than light oil.
At
the same time most citizens also recognize that investments in
renewable forms of energy remain small, costly and dispersed.
Moreover they produce electricity, not liquid fuel.
So
that's the first challenge. How does a society maintain an expensive
17 terawatt diet when the cost of its primary energy supply hits
triple digits and the so-called replacements are neither as versatile
or portable as oil?
But
here's another twist. If the rest of the world were to adopt the
lifestyles of the average North American who now consumes 24 barrels
of oil (and lots more electricity) civilization would require a
fivefold increase in energy consumption. That's 77 terawatts.
To
entertain a global population of 9.5 billion in 2050 on North
Americans standards multiplies the challenge again.
Such
a policy would take another 268 terawatts or 16 times the current
level of energy spending. (Just to energize nine billion people
living at current Chinese standards would take at least 34 terawatts
or a near tripling of current rates.)

These
ungainly figures invite several more conundrums. The amount of energy
that can be harvested from the planet on an annual basis is about 77
terawatts. So any business as usual case based on exporting North
American energy lifestyles to China and India totally busts the
world's energy bank.
A
third problem arises from the atmospheric pollution created by the
burning of fossil fuels over more than 150 years. To avoid
catastrophic global warming and runaway ocean acidification,
scientists calculate that society requires a massive energy
conversion to renewables beginning yesterday.
Such
a program means converting the current energy budget of 17 terawatts
from mostly fossil fuels to 14 terawatts from renewables within 25
years. Such a revolution would reduce the fossil fuel share of the
energy mix to about three terawatts a day.
Wind
farm continents?
But
is such a feat even possible given renewables low profile energy in a
debt-ridden world?
The
U.S. inventor and engineer Saul Griffith calculates that that world
would have to industrialize a landmass the size of Australia with
wind farms, solar arrays and algae biofuel factories to achieve such
a climate stabilization goal.
He
calls this unmade alternative geography "Renewistan," and
compares the scale of the endeavor to getting all the combatants in
the Second World War fighting on the same side for 25 years in a row.
Few environmentalists appreciate the magnitude or the cost of this
challenge.
In
the end, there are several different ways of answering the terawatt
challenge. The politically correct and dominant approach is denial.
But one way or another the globe must increase either renewable
energy supplies, decrease fossil fuel use or lower population levels.
Or achieve all three simultaneously.
But
whatever nations choose or deny, ordinary citizens face years of
political and economic volatility in the years ahead.
And
the first thing we need to acknowledge and understand about energy
transitions is that they do not arrive fully formed or in polite
clothing.
The
long switch from wood to coal was driven by the systematic
deforestation of Europe while the difficult shift from human slavery
to inanimate slaves energized by steam took one of the world's most
dramatic protest movements: abolition.
Realism
and hope
History
shows that energy transitions are invariably a utopian's worst
nightmare or a novelist's best idea: they are protracted, difficult
and unpredictable.
And
one more thing: energy transitions are often ripe with conflict.
All
the more reason to begin today thinking and talking about that
transition, and so this is the first of many articles to come in a
series we are calling "The Big Shift" -- a clear-eyed
exploration of what limits we face in our fossil fuel energy
supplies, the potential of green energy, the resilience of our
societies, the fragility of our political systems.
This
series seeks to provide merely the most realistic information and
well grounded analyses available. There's no usefulness in sugar
coating that produces false optimism that in turn might lull us into
complacency at a moment when critical technological and political
shifts must be anticipated and navigated. At the same time, hope
begins with recognizing the challenges we face and the opportunities
they present. Once gauged with clarity, we can get on with the task
at hand, minimizing the risk and hardship that any big shift
necessarily entails.
