Earth, People, Energy |
Energy. It's one of the most
intractable preoccupations of world governments these days.
We learned in high school physics that
you can't make energy; you can capture it, you can store it
but you can't make it. Nature stores the sun's energy in ingenious
ways: in the berries we pick and eat, in the coal and oil in the
ground, in the wind that drives dynamos, in the snows that fall on
mountain tops to melt in the spring and rush down again to drive
hydro generators.
Two days ago, we made a quick trip to
Saskatoon, I hosted a museum tour, we packed and hauled several
carloads of stuff to the condo and by evening, any energy I had
captured through eating and stored in my muscles had been spent and I
was running on empty. What I was feeling is what the earth is
feeling; too much energy demand, not enough charge in the batteries.
But my case was renewable. I could eat
stored energy, rest to let my batteries be recharged with it and get
up to face another day.
The problem is not so much that we
can't capture and store energy enough to move our cars and trucks and
trains and airplanes, it's that the processes required to capture
and store it threaten to destroy us: greenhouse gasses that
contribute to global warming, pollution that makes air in China and
Mexico city unbreathable, methane gas release that contaminates water
supplies, destruction of arable land and life-giving forests.
So the challenge governments face is to
capture more and more energy to satisfy the burgeoning demands of a
growing population while cutting back on those processes that are—in
the end—robbing Peter to pay Paul.
We've made considerable strides
in reducing our demands as in more energy-efficient homes, cars that
consume less fuel per kilometre, light bulbs that provide more light
energy and less heat energy, etc. But I'm pretty sure that the
solution for phasing out fossil fuel energy consumption will require
two things: a more serious effort to switch to non-polluting wind,
sun and tides energy and a massive tax on energy use so that
individual households and industries are actually required to reduce
consumption or face significant consequences.
B.C.'s carbon tax is a move in that
direction but if Naomi Klein (This Changes Everything)
is right, the cap and trade alternative is a farce, a way to put a
better face on industrial pollution without actually reducing world
carbon emissions appreciably. The NDP government in Alberta has just
announced tax disincentives to make carbon dioxide emitters get
serious about reducing their contributions to global warming.
We all want to be
comfortable and happy, entertained and “massaged.” For some, for
instance, that currently means flying to exotic places and warm
beaches whenever means and schedules allow. This won't be possible in
a post fossil fuel, energy-efficient world. At present, it's only an
option for the top 10% (more or less) of world citizens, the same 10%
that are consuming multiples of actually-required energy.
In the future
world, people won't live in massive detached homes; condos and
apartments require far less energy per person than stand-alone homes.
They may not own cars but rely instead on commuter trains to get them
to work.
Question is, can we
be happy living and working closer to home? Can we relearn what it
means to take pleasure in small things, in making music, in community
dances, in the parks and flower beds just across the road, in a new
kind of culture that is far less demanding of energy stored in the
earth than on energy delivered daily by a sun that has never yet failed
to shine on us?
Can we rediscover
the community that actually includes our next-door neighbours?
