Decent Essays

According to this article written by David Pimentel, Alison Marklein, Megan A. Toth, Marissa N. Karpoff, Gillian S. Paul, Robert McCormack, Joanna Kyriazis, and Tim Krueger, the production of biofuels is not only energetically wasteful in most circumstances, but it is also causing food shortages throughout the world. By creating biofuels throughout United States, we are not only using up valuable farmlands, but we are actually becoming more dependent upon foreign oil.
Throughout this article several statistics are given to show how energetically unfavorable the production of biofuels really is. Not only does the production of biofuels require huge amounts of resources like water, cropland, and chemical fertilizers, but in many cases it also consumes more net energy in fossil fuels than it produces in alternative energy resources. Some examples of biofuel production throughout the world include biomass resources, corn ethanol, grass and cellulosic ethanol, soybean biodiesel, and algae for oil production.
Renewable biomass resources on planet Earth amount to nearly 92 quads or 19% of the global energy use per year. One quad is equal to 1 quadrillion or 1015 BTU’s. To place this into perspective, a little over 1,000 BTU’s are in a peanut butter and jelly sandwich. The majority of these biomass resources come from wood harvested from forests throughout the world. Included in this biomass calculation is the total forest biomass production that yields 38 quads or 8% of the
