Active learning ideas
Energy Conservation focuses on reducing energy demand through efficiency and behavioral change. Students examine strategies across the domestic, industrial, and transport sectors, from high-tech solutions like smart grids and aerodynamic design to simple measures like loft insulation. This unit emphasizes that the 'cleanest energy is the energy we don't use,' aligning with AQA 3.3.4.
Activity 01
Students work in groups to conduct a 'walk-through' audit of the school building. They identify areas of energy waste (e.g., poorly insulated windows, lights left on, inefficient heating) and produce a costed proposal for improvements to present to the school management.
How can domestic properties be insulated effectively?
Activity 02
Groups are given a budget and a set of 'building components' (e.g., triple glazing, heat pumps, solar thermal, hempcrete insulation). They must design a home that minimizes energy use while remaining affordable, then 'test' its performance against a simulated winter week.
What are the benefits of aerodynamic transport design?
Activity 03
Students are given a scenario where a family buys a more fuel-efficient car but then decides to drive further because it's cheaper. They discuss in pairs why this happens and how policy (like fuel taxes) could prevent this 'rebound' from wiping out the energy savings.
How do smart grids improve energy efficiency?
A few notes on teaching this unit
Watch Out for These Misconceptions
Energy efficiency and energy conservation are the same thing.
Efficiency is about using less energy to provide the same service (e.g., an LED bulb), while conservation is about using less of the service (e.g., turning the light off). A simple sorting activity of different actions helps students distinguish between technological and behavioral changes.
New technology is always the best way to save energy.
Students often overlook low-tech, high-impact solutions like better insulation or passive solar gain. A comparative 'cost-per-tonne-of-CO2-saved' activity helps students see that simple building fabric improvements are often more effective than expensive gadgets.
