Energy and Water

It is great to see that a fresh discussion has begun about the Geo-Politics of Biofuels. The reality of the current thrust and parry between Lula and Chavez, has more to do with spheres of influence than what commodity we fill our gas tanks with. If one were to think critically about the impact of foods being diverted from our food chain to go towards energy demands, then one misses the fact that food supplies globally in key crops are already cramped given consumption patterns from nations like India and China. Additionally consider the fact that soy as a feedstock for biodiesel has not nearly peaked in Brazil. What most commentators are missing in their fundamental analysis is that the underlying resource whose finite volume will be the ultimate arbiter of our future energy shock, is actually water. Realistically, the next level of energy research should be driven by an understanding of the dynamics of water's availability as a factor in the outer limits of biofuels production. As we examine this, the penultimate conclusion might see water rich nations become the Blue version of OPEC. (Comment by Saif Y. Ishoof, 19 April 2007.)
