Energy Dependence


Every day, the United States sends $1 billion offshore to finance its appetite for fossil fuels, a situation recognized for decades as a threat to national security and energy independence.

In 1974, President Richard Nixon was the first in a long line of chief executives to promise reductions in energy from abroad. But the percentage of U.S. oil imports since then has nearly doubled.

Meanwhile, fossil fuels are the source of the greenhouse gases blamed for global climate change, an ongoing problem that has engendered another round of presidential promises. The Obama White House recently pledged to reduce such gases 83 percent by 2050, with 2005 as a baseline year.

Reducing dependence on foreign oil and reducing greenhouse gases are the two major challenges of U.S. energy systems, a visiting federal energy official told a Harvard audience Tuesday (Sept. 21). To meet these challenges, he said, the government’s best role is to mitigate risk in the energy industry and to leverage innovation.

Theoretical physicist Steven Koonin, undersecretary for science at the U.S. Department of Energy (DOE), opened this year’s Future of Energy lecture series, sponsored by the Harvard University Center for the Environment.

Koonin is a rare veteran of all three spheres in the energy puzzle: academe, business, and government. He has been a professor and provost (California Institute of Technology), an industry chief scientist (BP), and since last year a federal bureaucrat. At the DOE, Koonin is the science office’s chief research officer. If you count last year’s American Recovery and Reinvestment Act, he has influence over $100 million in funding for energy-related research, loans, and loan guarantees.

Koonin offered a broad perspective in his session opening the series. Center director and climate scientist Daniel Schrag said that the next lecture — coming Oct. 12 by an executive whose company makes tiny $2,000 cars — will get down to the details of managing Earth’s energy future.

Koonin told a capacity crowd at Science Center D that the U.S. energy business is complex, operates by calculating risk and profit in the long term, and approaches innovation slowly and conservatively. After all, he said, any decision on technology will create infrastructures — and costs — that last for decades.

“The energy business is not simple,” said Koonin, “and the people in it are not troglodytes.”

Nor are they venture capitalists, said Koonin. In that economic sector, risk and innovation are king, but profits get taken fast. “Exit time” is measured in years, not decades. And average funding pools — at $150 million — are not enough to prompt scaled-up change in energy systems. “The energy business,” said Koonin, “is not the venture capital business.”

He said government does not have sufficient capital of its own to scale up the needed changes in energy systems, which remain largely in private hands. Change only will happen if it is profitable or mandated, said Koonin. Government tax credits are powerful incentives for change, he said. Wind industry installations went up when the credits were in place, and slipped when the credits disappeared.

Government can also play a big role in the essential steps that Koonin outlined to improve energy security and reduce greenhouse gases. Among them:
- Promote vehicle efficiency. The technology is in hand to increase the fuel efficiency of American cars by 30 percent, for about $2,000 a vehicle.
- Conserve. Koonin offered “a sense of what is possible” in one example. If all motorists in Texas simply drove at the speed limit, U.S. gas consumption would come down 12 percent.
- Gradually electrify the U.S. vehicle fleet.
- Pursue unconventional fuels.
- Decrease the energy intensity of buildings. Heating, cooling, lighting, and ventilating use 40 percent of U.S. energy.
- Develop “smart grids” for energy transmission and storage. That means adding digital sensing, measuring, and control devices to increase reliability and efficiency.
- Set a price for carbon, by cap-and-trade or other means.
Explore emerging technologies such as concentrated solar power and carbon capture and storage.

Changing energy systems is difficult and slow, said Koonin, who reviewed the historical record from 1850 onward. Industry favors change on “decadal time scales,” he said. The gas-scrubbing systems for coal plants, for instance, took 40 years to develop and perfect.

But government can help industry to manage the capital risk of energy innovation, said Koonin, and is already accelerating invention in what he called “a new set of research structures.” These include a network of national labs, the federal “energy hub” concept, and, for short-term projects, the federal Advanced Research Projects Agency — Energy.

Koonin’s decades of research often involved large-scale rapid computing, so he sees another bright side to the energy innovation picture: big and fast computer simulations of the kind that in the 1990s were used to replace U.S. nuclear testing. That alone, he said, accelerated computer technology by a factor of 10,000.

The same predictive simulation capability can be focused on U.S. energy issues, said Koonin. “We need to do more of this, faster.

On This Cold Night

On this cold night in the third autumn month,
A solitary old man, tranquil and leisurely.
Laying down late after the lamp’s burnt out,
Pleasantly he sleeps with the sound of rain.
As ash lay resting in the stove still warm from the fire,
Its fragrance increases the warmth of quilt and covers.
At dawn, clear but cold, he stirs not –
Frosted leaves at their crimson fullness.

- Bai juyi (772-846)

The Fourth Noble Truth


All experience is preceded by mind,
 Led by mind,
 Made by mind.
Speak or act with a corrupted mind,
 And suffering follows
As the wagon wheel follows the hoof of the ox.
All experience is preceded by mind,
 Led by mind,
 Made by mind.
Speak or act with a peaceful mind,
 And happiness follows
Like a never-departing shadow.

Wallace Stevens

    Wallace Stevens (1879-1955)

    Contributing Editor: Linda W. Wagner-Martin

    Classroom Issues and Strategies

    The sheer difficulty of apprehending meaning from some of Stevens's poems turns many students away. Yet Stevens is one of the most apt voices to speak about the perfection, and the perfectibility, of the poem-- the supreme fiction in the writer's, and the reader's, lives. If students can read Stevens's poems well, they will probably be able to read anything in the text. The elusiveness of meaning is one key difficulty: Stevens's valiant attempts to avoid paraphrase, to lose himself in brilliant language, to slide into repetition and assonantal patterns without warning. His work demands complete concentration, and complete sympathy, from his readers. Most students cannot give poetry either of these tributes without some preparation. Close reading, usually aloud, helps. The well-known Stevens language magic has to be experienced, and since the poems are difficult, asking students to work on them alone, in isolation, is not the best tactic. Beginning with the poems by Stevens might make reading T. S. EliotRobert Frost, and William Carlos Williams much easier, so I would make this selection central to the study of modern American poetry.

    Major Themes, Historical Perspectives, and Personal Issues

    The value of poetry (and all art); the accessibility of great moral, and mortal, themes through language; the impenetrability of most human relationships; the evanescence of formalized belief systems, including religion; the frustration of imperfection; and others. Stevens often builds from historical and/or philosophical knowledge, expecting "fact" to serve as counterpoint for his readers' more imaginative exploits. But this technique is not meant to lead to easy or facile explication. It is a way of contrasting the predictable and the truly valuable, the imaginary.

    Significant Form, Style, or Artistic Conventions

    Stevens's intricate stanza and rhyme patterns are a school of poetry in themselves, and each of his poems should be studied as a crafted object. His work fits well with that of T. S. Eliot, as does some of his aesthetic rationale: "Poetry is not personal." "The real is only the base. But it is the base." "In poetry, you must love the words, the ideas and the images and rhythms with all your capacity to love anything at all." "Poetry must be irrational." "The purpose of poetry is to make life complete in itself." "Poetry increases the feeling for reality." "In the absence of a belief in God, the mind turns to its own creations and examines them, not alone from the aesthetic point of view, but for what they reveal, for what they validate and invalidate."

    Original Audience

    Modernism was so specific a mood and time that students must understand the modernists' rage for control of craft, the emphasis on the formalism of the way an art object was formed, and the importance craft held for all parts of the artist's life. Once those conventions are described, and Stevens placed in this period, his own distinctions from the group of modernists will be clearer. ("Not all objects are equal. The vice of imagism was that it did not recognize this." "A change of style is a change of subject." "In the long run the truth does not matter.") Conscious of all the elements of form, Stevens yet overlays his work with a heavily philosophical intention, and the shelves of commentary on his poetry have been occasioned because that commentary is, in many cases, useful.

Dragon Fly




 


"The globular eyes
Of the quivering dragonfly
Are mirrored in the splendid pond
Swarming with mysterious life."
