Oil diplomat or man of the people?
On the defensive after George Bush and Lula da Silva of Brazil started getting friendly over ethanol, Hugo Chavez has now backed away from plans for building a massive array of 29 ethanol plants.
His rationale tears a page from the nascent biofuel backlash movement, saying that land should be used to feed people, not to fill "rich people's cars." As with most things Chavez, this is probably largely about politics and somewhat about people: he doesn't want to be outflanked by Bush's new foothold in the region. But it's a stand that will win him points in many quarters, and he's expected to make it again later this month at a South American energy summit.

Biofuel facilities that use fossil fuels help no one, waste resources.
The Onion, America's Finest News Source (TM), once told of a special device for dealing with a lost TV remote: a remote you could use to make the other TV remote beep, so you could find it underneath the discarded pizza boxes and such.
Little did the Onion writers know that Big Coal and Corporate Agribusiness would apply that same principle to produce a horde of monsters, the so-called "biofuels plants," facilities with a voracious appetite for fossil fuels, particularly yummy coal.

Not — yet, anyway
I know there are Gristmill readers with high hopes for algae-based biofuels. They will enjoy this piece in Popular Mechanics. Here’s the hope: Solix addresses these problems [algae’s finicky growing habits] by containing the algae in closed “photobioreactors” — triangular chambers made from sheets of polyethylene plastic (similar to a painter’s dropcloth) — and bubbling […]

We need to rethink all food based biofuels
The lion's share of biofuel bashing on Grist deals with corn ethanol, because we Americans primarily use gasoline for our cars and ethanol runs fine in them, with few modifications. However, our pals in Europe drive a lot of diesel cars and the biofuel crisis over there revolves primarily around biodiesel. I think it is time we recognize that their problem is also our problem. A comment from Pcarbo alerted me to Monbiot's latest take on biofuels. He has now gone so far as to propose a ...
... moratorium on all targets and incentives for biofuels, until a second generation of fuels can be produced for less than it costs to make fuel from palm oil or sugar cane.

I heart David Tilman
Tilman on biofuels in Sunday's Washington Post: eminently readable and reasonable on parsing the differences between good and bad biofuels, drops in ethanol production in Brazil, what renewable really means, and where we should go from here.
The op-ed's based on his December Science study, which was discussed here. Everything he writes makes so much sense. Why can't all scientists be this articulate?

Edwards, Canada, and now South Africa
Former Senator John Edwards (D-N.C.) -- now a presidential hopeful -- has just published his latest energy plan. One important plank of that plan foresees the nation producing (not just consuming, which would allow for imports) 65 billion gallons a year of ethanol by 2025. ("I'll meet your bid for 2030, Barack, and raise it by five billion!")
If the 51 cents a gallon volumetric ethanol excise tax credit (VEETC) is extended beyond the end of 2010 -- as most commentators and even the USDA expect will happen -- here's what the cumulative cost to the U.S. Treasury would be from 2007 through 2025, assuming straight-line growth:
Almost $350 billion (=$0.51 x 19 x [7+(65-7)/2]).

Or a new way forward?
File this under possibly hopeful news: Researchers at Purdue are calling an approach that gasifies biomass to make liquid fuels a "hybrid hydrogen-carbon process," or H2CAR. Read the article for the straight scoop, but it's basically adding hydrogen to biomass from a "carbon-free" energy source (solar? wind? nukes?), via gasification.
The process would be more efficient than current biofuel production because it'd suppress the formation of carbon dioxide and convert all of the carbon atoms to fuel. Is it just hot air? And if this process is powered by nukes, that's a whole new question.
