The energy revolution will not be televised

Three recent news items remind us that energy transitions take time, a lot of time--far too much time to be shrunk down into a television special, a few talking points, or the next big energy idea.

For example, the complex management task of putting together the international fusion research project called the International Thermonuclear Experimental Reactor (ITER) has resulted in estimated final costs that have tripled since the 2006 launch. Fusion could theoretically offer clean and abundant energy almost indefinitely because it uses ubiquitous hydrogen* as fuel and creates helium in the process. (Water you'll recall is two hydrogen atoms and one oxygen atom and is therefore the most abundant source of hydrogen.)

Despite nine years of effort, ITER has yet to carry out a single experiment; and, the project is not expected to do so for another four years. The idea for such an international project was hatched in 1985 during a summit between U.S. President Ronald Reagan and Mikhail Gorbachev, the leader of what was then still called the Soviet Union. Thirty years later fusion is still receding into the horizon of our energy future.

Is the slowdown in productivity growth a result of energy costs?

Slowing productivity growth in the United States has been in the news in recent months. It has become a concern to policymakers because they believe it is one of the primary contributors to a middle-class economic squeeze according to the annual report of the White House Council of Economic Advisors.

Simply put, productivity growth refers to the growth in economic output per worker or more precisely, per hour of work. When this growth slows, the potential for real wage increases diminishes since the growth in wages typically reflects the ability of workers to create more output per unit of time.

To the obstensibly naive observer the following idea may seem a plausible explanation: Higher-cost energy inputs into the production of goods and services reduce productivity growth because the economic output per dollar of energy consumed declines. And, though energy inputs aren't the only thing to consider, they are important. The high energy prices of the last decade or so may be, in part, responsible for low productivity growth. (Conversely, low energy costs would imply more output per dollar of energy consumed.)

Stephen Toulmin welcomes you to the end of modernity

Historian and philosopher of science Stephen Toulmin welcomes you to the end of modernity, at least modernity as we've imagined it. By modernity, he does not mean modern gadgets. By end he does not mean an end to progress in the natural sciences, nor in human affairs in general. Instead, he is talking about a way of thinking which has held us in thrall since the 17th century, for good and for ill, and is now giving way fitfully to a new (he would say "old"), more flexible worldview.

Toulmin's book Cosmopolis: The Hidden Agenda of Modernity is not new. It was published in 1990. Its argument will be of interest to anyone concerned with issues of sustainability including climate change and resource depletion.

Toulmin offers an historical account of how this view we call modern arose, and he catalogues its tenets. The ones that are of particular interest to me are as follows:

  • Nature is governed by fixed laws set up at the Creation.
  • The material substance of physical nature is essentially inert.
  • Physical objects and processes cannot think.
  • At the Creation, God combined natural objects into stable systems.
  • The essence of humanity is rational thought and action.

Terms of debate: Destroying vs altering nature, the fragile vs the resilient Earth

Last week's piece drew responses that throw into relief how much the language we use depends on our most basic assumptions about how the world works. If left unexamined, that language leads to further conclusions that go unchallenged because the underlying assumptions are never scrutinized.

I challenged the Breakthrough Institute's notion that humans are in one category and nature in another. If one views humans as merely a part of nature or the universe or the web of existence--however one chooses to name that which includes everything--then our role becomes distinctly different.

Under my assumption humans are embedded in the natural world. They are not the sole actors or agents in it, only one of countless actors, most of which we probably know nothing about. We cannot get one up on nature. We can only cooperate with its workings.

'An Ecomodernist Manifesto': Truth and confusion in the same breath

I really do want to applaud the Breakthrough Institute's recently released paper called "An Ecomodernist Manifesto." It speaks with candor about the possible catastrophic consequences of unchecked climate change. It recognizes the large footprint of humankind in the biosphere. It wants to address both, and it wants to do so in a way that offers a positive vision for the human future that will attract support and, above all, action.

But, I can't applaud it because of its underlying assumption: that humans are in one category and nature in another. The key paragraph starts with the key sentence:

Humans will always materially depend on nature to some degree. Even if a fully synthetic world were possible, many of us might still choose to continue to live more coupled with nature than human sustenance and technologies require. What decoupling offers is the possibility that humanity’s material dependence upon nature might be less destructive.

"Humans will always materially depend on nature to some degree." This statement seems reasonable only if humans and nature are in different categories. But, they aren't--a concept that is distressingly NOT clear to most everyone who styles himself or herself as an environmentalist. Humans and their creations are as much a part of nature as everything else. Humans don't "materially depend on nature to some degree." Humans are entirely and completely dependent on nature (of which they are a part) for EVERYTHING. Even every synthetic substance uses feedstocks and energy from the natural world.
