Woody Biomass as a SystemPart I: The Woody Biomass to Ethanol System
What Is Systems Thinking? • A strategy to help us think about • The whole picture (the system) • All of the parts of the system and how they interrelate • How changes to one part of the system can impact other parts of the system • A good strategy for thinking about complex issues and scenarios
What Is a System? • Systems have inputs and outputs • Input = something that enters the system; required for the processes of the system to occur • Output = something produced by the processes that occur within the system • A group of individual parts interacting to form a whole
System Example • Buses bringing students to school • What are the parts of the system? • What are the inputs? • What are the outputs? • What happens when a bus is one hour late? • How does this impact different parts of the system?
Brainstorm Can you think of additional examples of systems? What are the inputs and outputs of these systems?
TREE FARM GAS STATION ETHANOL PLANT Woody Biomass to Ethanol System • Using woody biomass to make ethanol (a liquid fuel) • Ethanol is mixed with gasoline to make E10 or E85 for vehicles • This system has 3 main components: • Each component has inputs and outputs
ActivityPart I: The Woody Biomass to Ethanol System Working with a partner, use the system cards to make a diagram of the woody biomass to ethanol system

What Is a Policy? • A deliberate plan of action to guide decisions and achieve rational outcomes • Developed in several stages • Issue identification • Policy formation • Policy implementation • Policy analysis and evaluation
Why Are Policies Important? • To address an identified issue by either reducing negative impacts or producing positive impacts
Impacts of a Policy • Impacts can be both intended and unintended • Impacts are difficult to predict • Issues are complex with many related factors (a system) • Unintended impacts may be caused by • Lack of knowledge • Imperfect implementation of the policy
Brainstorm Can you think of examples of recent local, state, national, or international policies? What are some impacts of these policies (intended and unintended)?
Recent Bioenergy Policies • International • Kyoto Protocol • National • Energy Independence and Security Act of 2007 • United States Farm Bill of 2008 • State • Florida Farm to Fuel Grants Program of 2007
ActivityPart Two: The Impact of a Policy Working in groups, predict the impacts of a specific policy on the woody biomass to ethanol system
