Biofuels and the Water-Energy Nexus: Perspectives for the United States

This paper provides an overview on the main impacts of biofuels production on water resources within the United States, with an emphasis on the corn-based ethanol market and the agricultural stage. The following issues are examined:

  • the relationship between biofuel production and water availability;
  • trends and policy options for future biofuel production and the tradeoffs for water scarcity;
  • technological changes in transportation fleet, with consequential effects on biofuels demand and water resources;
  • considerations for policy makers who seek to reduce the future impact of biofuels on water sustainability.
