Biofuels Deemed a Greenhouse Threat.

Almost all biofuels used today cause more greenhouse gas emissions than conventional fuels if the full emissions costs of producing these “green” fuels are taken into account, two studies being published Thursday have concluded.

The benefits of biofuels have come under increasing attack in recent months, as scientists took a closer look at the global environmental cost of their production. These latest studies, published in the prestigious journal Science, are likely to add to the controversy.

In their current state, biofuels may be a threat. But, I know that some studies that have been conducted in the past have used calculations based on farming done with tractors using non biofuels. The calculations are different when you assume that the farmers will use biofuels in their tractors.
Also, research is being done on switchgrass as a source for fuel that would cut down on the need to cultivate grasslands with other crops.
I am further remined of a science professor who told a class I was in that we needed the space-race, not because we needed to get to the moon, but because we needed, and have since benefitted, from the technology that had to be invented to get us there. I believe that one day the same argument will be made about biofuels. Biofuels are not that effecient or environmentally friendly now. But, in the near future they will be as we continue to use them and improve on the techology.
