Lecture Notes: Week 4 Lab - Sustainable Energy
Introduction
- Focus on sustainable energy and future energy sufficiency.
- Types of energy discussed:
- Non-renewable: fossil fuels, nuclear
- Renewable/Alternative: biofuels, solar, wind, hydroelectric
- Importance of lab: historically challenging for students.
Lab Overview
- Objective: Conduct a predictive energy demand study to reach at least the year 2060 without energy shortages.
- Penalty: Failure to reach 2060 results in point deduction.
Lab Instructions
-
Downloading Materials:
- Access the lab via a Word document with an embedded link.
- Note: The lab uses an archived simulator starting from 2010.
-
Lab Structure:
- Two main lessons:
- Managing Energy Resources
- Energy Efficiency
- Skip certain steps to simplify:
- Skip Step 1 in Managing Resources, proceed to Step 2.
- Do Step 1 in Energy Efficiency, skip Step 2.
Lesson 1: Managing Energy Resources
-
Context:
- Rising energy demand due to population growth and reliance on non-renewable resources.
- Fossil fuel combustion issues: CO2 emissions, ecological impacts.
-
Simulator Usage:
- Adjust energy source sliders to create a sustainable energy future, aiming to reach the year 2110.
- Key strategy: Maximize fossil fuels initially, especially coal, to meet early energy demands.
-
Recording Data:
- Record energy supply in joules for each decade.
- Meet a minimum requirement of reaching 2060.
Tips for Managing Energy Resources
- Prioritize fossil fuels initially.
- Transition towards alternative energy as non-renewables deplete.
- Aim for two attempts:
- First attempt: Focus on maximizing fossil fuels.
- Second attempt: Experiment with different strategies.
Lesson 2: Energy Efficiency
-
Purpose:
- Understand how to increase energy efficiency and its impact on energy demand.
-
Experiment Variables:
- Energy demand change
- Energy efficiency change
- Net carbon capture
-
Procedure:
- Conduct three separate experiments, adjusting variables to see effects on energy demand.
- Record efficiency, carbon capture, and year predictions in a data table.
Experiment Tips
- Begin with zero efficiency change and no carbon capture.
- Gradually increase efficiency and carbon capture in subsequent attempts.
- Consider impacts of population growth and technological changes on energy demand.
Key Insights
- Switching energy sources (e.g., from oil to coal) might still rely on fossil fuels.
- Electric vehicles, while reducing oil dependency, may increase coal consumption.
Conclusion
- The lab provides awareness on energy needs and challenges in sustaining a growing population.
- Encourage exploration and understanding of energy sustainability issues.
Note: Always refer back to the simulator instructions and the help section for any clarifications needed during the lab.
