Energy Secretary Bodman on Biofuels

U.S. DOE Secretary Samuel Bodman spoke at DOE's Biomass Conference on April 18. In his prepared remarks the Secretary acknowledged concerns about corn-based ethanol and the importance of developing the "next generation" of ethanol made from biomass products that are outside the food chain:
In all areas of our research and development, the impact on our global environment – including the impact of energy diversification on land and water resources and world food supplies – is an important part of the discussion. And it is an important consideration in our technical research. This has absolutely been the case when it comes to biofuels.

We’ve looked at the research and we’ve concluded that a diverse, sustainable set of biofuels-technologies will measurably improve our energy security and the health of our environment.

But to do this we must develop, produce, deliver and consume biofuels in an intelligent way and with an urgent focus on sustainability.

So, as we pursue diversity in our overall energy mix we must also pursue diversity in our biofuels. This means moving away gradually from ethanol produced from food stocks like corn.

Let me be clear: I am not minimizing the importance of ethanol made from corn - it is critical to our energy security and America’s farmers make an important contribution to our energy security.

But what I am saying is that we need to develop and deploy the next generation of ethanol - ethanol and other products made from biomass products that are outside the food chain.

In my view, this means cellulosic fuels made from agricultural waste products and crops like switchgrass, which can be grown and regenerated on less desirable lands.
The Wall Street Journal's Environmental Capital blog describes Secretary Bodman's remarks as "astride the fence", midway between the view of some U.N. officials that producing biofuels is a "crime against humanity" and the view of Brazilian President Luiz Inacio Lula da Silva that denying the developing world alternative fuels would be the real crime.

From our point of view, Secretary Bodman is right to focus on diversity in energy supply and to recognize that energy and environmental policies are inextricably linked. The Wall Street Journal's Environmental Capital blog reminds us that both are also linked to economic policy. That's why we favor producing copious amounts of reliable baseload electricity from an inedible, incombustible rock - uranium.

I think Secretary Bodman's remarks are right on track. I am please to see officials recognizing that food based crops used for biofuels are affecting our food supplies. For a safe food supply we must bring our food sources back home rather than depending on unregulated sources outside our country.

Another important point on ethanol (from corn or cellulose)is that a large amount of low-pressure steam is needed to distill it. Today this comes from burning natural gas. In the future this steam could come from nuclear plants that would co-generate electricity and steam. Current corn ethanol has a very small net energy benefit, and using nuclear steam would roughly double the energy benefit.

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Seeing the Light on Nuclear Energy

If you think that there is plenty of electricity, that the air is clean enough and that nuclear power is a just one among many options for meeting human needs, then you are probably over-focused on the United States or Western Europe. Even then, you’d be wrong.

That’s the idea at the heart of a new book, “Seeing the Light: The Case for Nuclear Power in the 21st Century,” by Scott L. Montgomery, a geoscientist and energy expert, and Thomas Graham Jr., a retired ambassador and arms control expert.


Billions of people live in energy poverty, they write, and even those who don’t, those who live in places where there is always an electric outlet or a light switch handy, we need to unmake the last 200 years of energy history, and move to non-carbon sources. Energy is integral to our lives but the authors cite a World Health Organization estimate that more than 6.5 million people die each year from air pollution.  In addition, they say, the global climate is heading for ruinous instability.
