Background:

Viewing the larger scope- liquid fuels concerns•1970 versus 2005•Supply Driven•Demand Driven

Department of Agricultural EconomicsPurdue University

Supply Driven:

•Ethanol (grain and cellulosic)•Liquids from Coal•Hydrogen•Middle East & USSR•Price

3

Demand Driven:

•Price•Rationing•Regulation

New Technology/Conservation•Transportation Infrastructure

Trajectory of Current Ethanol Policy

Department of Agricultural EconomicsPurdue University

•Crop Prices & Cropping Impacts•Subsidy/Renewable Fuel Standards Costs

Role of Transition Policy

•Improved Energy output per water/energy input•Long term sustainability life cycle based•Reduced loadings of nutrients, pesticides & sediments•Lower net Carbon emissions

Where Might We Go?

Department of Agricultural EconomicsPurdue University

•Link to demand and consider cost effectiveness•Consider Biofuels in the context of liquid fuels overall•Consider a Transition Policy with performance standards
