Recent studies point out that the cost to grow and produce biofuels is worse for the planet than gasoline

Two studies published in the journal Science shed some light into the overall cost of biofuels. Taken into account is not only the greenhouse emissions generated by burning biofuels but all of the emissions generated when producing biofuels.

According to one article the estimated impact of using corn based ethanol is double the amount of greenhouse emissions currently being produced by gasoline over a 30 year time span. An alternative method of ethanol production using switchgrass is estimated to increase emissions by a whopping 50 percent.

With governments around the world pushing to establish hard mandates on the use of biofuels and other renewable methods of energy production, we could be setting ourselves up to cause more harm than good. The U.S. Congress has set a target to raise the use of biofuels from 7.5 billion gallons to 36 billion gallons by 2022. That’s a 480 percent increase. That would push greenhouse gas production in the U.S. up by an order of magnitude.

At the same time, in order to produce these biofuels, farmland is cleared for the growth of ethanol-reliant crops. Clearing land for farming has a cost in greenhouse emissions, as does growing and harvesting these crops. Add that in to the cost of refining and burning these crops and we are generating far more emissions than simply using gasoline and oil.

Scientists in the U.S. and Europe have written letters to their respective governments warning them that biofuels in their current form will only exacerbate the production of greenhouse emissions and push the world further towards climate change.

The United Nations stated it wants to continue with the production of biofuels and reap any potential benefits. The organization admitted however that biofuels are not the silver bullet they were led to believe.

Dr. Searchinger is advocating a switch in gears for the production of biofuels. The use of organic waste in the production of biofuels would get around the problem of clearing and farming previously unused lands which cause so much of the greenhouse emissions that hold back any potential benefits of using biofuels. Using organic waste could also be well on it’s way to becoming a reality thanks to recent breakthroughs in this field.

As pointed out by masher, there's no free ride when it comes to any energy production. The fertilizers, machine equipment, infrastructure all must come from somewhere; and that's still "carbon" based -- and it's not a trivial footprint either.

I can't wait until someone proposes oxygen credits.

That might be funny if there wasn't a real possibility of someone trying it.

I agree with you, however what about the new Hydrogen fuel cells that use bacteria to break down organic material. My understanding was that this could use waste byproducts such as raw-sewage to create truck-loads of energy that had the upshot of producing clean water.
