Obama and Clinton Still Calling for More Biofuels

So far it appears that neither Barack Obama nor Hillary Clinton have adjusted their policies on biofuels to the new scientific realization that large scale production of both ethanol and biodiesel are contributing to global warming rather than being a partial solution. The other major presidential candidate, John McCain, doesn’t seem to have any policy on biofuels or for that matter on how to reduce greenhouse gases from transportation as his website simply says that he offers to limit carbon emissions “by harnessing market forces that will bring advanced technologies, such as nuclear energy, to the market faster, reduce our dependence on foreign supplies of energy, and see to it that America leads in a way that ensures all nations do their rightful share.” At least Obama and Clinton do get down to some specifics.

Barack Obama’s website says that he “will require 36 billion gallons of renewable fuels to be included in the fuel supply by 2022 and will increase that to at least 60 billion gallons of advanced biofuels like cellulosic ethanol by 2030.”

Hillary Clinton’s website says that she will have “60 billion gallons of home-grown biofuels available for cars and trucks by 2030.”

That’s a lot of biofuels to be promising considering that so far the use of biofuels has led to increasing food prices around the world and increased emissions of greenhouse gases in instances where land was cleared for planting. Cellulosic ethanol at this point remains unproven as a source of fuel and hardly something to count on.

What we should be hearing from all three candidates is that they want to put a halt to large scale production of ethanol and biodiesel and carefully review whether the using these fuels in place of petroleum-based fuels at this time makes any sense. Unfortunately that is not what they want to hear in Iowa or neighboring farm states so there is little if any chance anyone will be hearing it from the candidates very soon.

Biofuels Are Losing Their Clean Energy Label

Heralded as an answer to both attaining energy independence and limiting global warming biofuels have enjoyed great popularity during the last few years even though concerns about using crops for fuel instead of food has raised concerns in many places. Biofuels have become so popular in fact that last year Congress passed legislation mandating that the US produce 36 billion gallons of the stuff annually by 2022. However, here we are only a few months after this legislation was passed and signed and it appears that the wheels are starting to come off the biofuels bandwagon. Biofuels have lost their “green” appeal almost overnight because scientists have found that rather than reducing greenhouse gas emissions compared with burning gasoline biofuels for the most part increase greenhouse gas emissions.

It turns out that the main problem with biofuels is that when land clearing to plant the crops is included in the equation the amount of carbon released from the cleared plants is so great that it dwarfs the carbon saved by using biofuels versus gasoline. Biofuels were thought to produce less carbon emissions because the next crop of plants sequester as much carbon as is released by burning ethanol or biodiesel. The crop clearing “inconvenient truth” is described in a Time magazine article by Michael Grunwald called The Clean Energy Scam. Grunwald concludes his article by saying that:

Advocates are always careful to point out that biofuels are only part of the solution to global warming, that the world also needs more energy-efficient light bulbs and homes and factories and lifestyles. And the world does need all those things. But the world is still going to be fighting an uphill battle until it realizes that right now, biofuels aren't part of the solution at all. They're part of the problem.

The challenge facing the environmentalists is convince the public and politicians that biofuels should not be used after there has been so much written and said about the benefits of using biofuels. This could be a tough sell.
