We have an energy problem. Everyone
knows that, but there is disagreement on both what that problem
exactly is and what we should do about it. I know this is a very
complex issue and I am not going to go into all of the different
complicating factors in this post. That is more like something that
could fill a book. So I am going to focus on looking to the future
and how to plan and act to make that future the best it can be.
Regardless of the timeline that one
might espouse, we can all agree that fossil fuels are finite. Even
if you think we have well over a hundred year supply and that burning
all of that won't harm the planet and human civilization, you MUST
agree that eventually the fossil fuel resources will be so diminished
as to make our reliance on them not just unsustainable but
catastrophically disastrous.
That being said, I suggest that we look
forward to that future. Imagine what that future would be like.
What are our energy needs likely to be? How are we likely to obtain
all of that energy and from what source. While there are a number of
options, I am one of those that believes that an “all of the above”
non-fossil fuel scenario is the most likely to provide a
sustainable energy supply for the medium term future, and by that I
mean the next couple of hundred years.
What are those non-fossil fuel energy
sources? The most obvious is the sun. Our ability to harness a fuel
source that does not originate on this planet, provides us with a
source that we are unable to deplete. That is the best hope for the
future. It is important to note that the wind is generated by the
unequal heating of the earth by the sun and is thus an indirect form
of solar energy. Hydro-electric energy is also indirectly sourced by
the sun's heat warming the earth's water, evaporating it and then
precipitating it at a higher altitude creating potential energy.
Large scale wind and hydro require infrastructure that has impacts on
the earth, but compromises must be made. We have simply
over-populated our planet to the extent that we have no choice.
Large scale photo-voltaic and concentrated solar installations also
have these impacts. The decentralization of energy production
decreases the impacts of large scale facilities. Small scale
individual wind and solar arrays on homes and businesses decreases
the need for large scale facilities. Nuclear energy has the
potential to help us in this long transition, but the scale of the
reactors needs to be brought down too, to decrease the threat of
large scale catastrophe as we have recently experienced. More,
smaller reactors like those in submarines and aircraft carriers would
spread the risk while minimizing the impact of the inevitable
accident. The transition to Thorium as a nuclear fuel source is
another positive change that could provide safer nuclear energy as
part of the energy we need.
Without going further into the various
types of non-fossil fuel energy sources, I want to get back to
envisioning the future where we are not dependent on fossil fuels and
are getting the energy we need from these non-fossil alternatives.
However one might envision that future,
it would be beneficial to consider the transition to that future. My
thought is that if we can see that future in even the vaguest of
levels of prediction, it would behoove us to make that transition as
quickly as possible. In doing so, we push our civilization forward
to that future. Those who lead that push are those who will profit
the most from that transition.
At this point, the United States is not
leading the push. The U.S. adoption of alternatives is well below
countries that have made it their policy to proceed with a transition
to alternative energy. As fossil fuels are depleted, and become more
expensive to extract, and their effects on the environment are
realized in a more and more negative way. Those countries that have
made a transition will be at a huge competitive advantage.
So, I advocate for a focused push in
the United States toward that imagined future where fossil fuel
supply does not have us fighting for economic survival. Where fossil
fuel pollution does not ravage our planet. Where we lead in the push
to a new energy future. The technologies are already in place. They
will only improve as time goes on. We must adopt those technologies
to the fullest extent possible as soon as possible.
I envision a future where our ability
to harness the sun to produce the energy we need makes energy so
available and is so inexpensive that has little to no impact on our
daily lives. Let's get there as soon as we can.
