Grow mass amounts of algae and produce 20000+ gallons of bio-fuel on one acre. With the amount of farm space of 1/10 the size of New Mexico we could produce enough fuel to fill the United States’ need for oil.

Technologies that appear at first blush and in the lab to be both benign and efficacious often turn out, upon widespread implementation, to be counter-productive or even detrimental. We have yet to accurately capture and model the complexity of reality. Emergent phenomena, unintended consequences, unexpected and undesirable by-products, ungovernable economic and other processes all conspire to adversely affect the trajectories of even the most thoroughly studied inventions.
Biofuels are the poster children of such good intentions gone terribly awry. Rather than retard global warming, scientists (such as Holly Gibbs, a postdoctoral researcher at Stanford’s Woods Institute for the Environment, Matt Struebig from Queen Mary, University of London, and Emily Fitzherbert from the Zoological Society of London and University of East Anglia) are now warning that they may enhance and accelerate it by encouraging deforestation in the tropics. Indeed, the higher the prices fetched by biofuels, the more rainforests are being ferociously decimated in the quest for arable land.
Moreover, biofuels are energy-inefficient: their production consumes more energy than they yield in burning. The disastrous effect they have on food prices is amply documented. Another study demonstrates that their consumption releases more carbon dioxide into the atmosphere than the quantity of fossil fuels that they replace.
This “carbon debt” is especially true if we take into account the gases released by the incineration of trees mowed down to make place for the (often state subsidized) cultivation of biofuels. There is also a “biodiversity debt”: up to five-sixths of indigenous species are extinguished once a forest is cleared to make way for oil palm plantations, for instance.
Though much hyped, biofuels should not serve as part and parcel of the energy policy mix. Some wonks suggest that biofuels should be allowed to be grown only on marginal or degraded land. But, this would require enormous investments in fertilizers and other technologies intended to halt soil erosion and nutrient leeching. From the point of view of environmental accounting, such tracts better be re-forested. Forests recycle rainwater, act as carbon skins, prevent floods, and serve as habitats to species, some of them endangered.
