Energy and climate change
Energy and climate change
All about energy In this unit, participants are invited to look at energy consumption and different ways to generate electricity. Participants are sensitised to the connection between energy consumption and climate change, and they discuss ways to save energy.
4 Energy and climate change
Time required Approx. 30 minutes
Method
Interactive game
• Poster or flipchart and pen • For each team: – Cards depicting everyday situations – Cards with details about energy consumption
Materials
Preparation
It’s best to find a suitable outdoor area, but the game can also be played in a large room. The workshop leader draws a baseline on the ground and from there one lane for each team. The participants use the "power consumption" cards to mark out the kWh usage for everyday activities on each lane. 0.1 kWh corresponds to one metre 1 . – 10cm: charging a smartphone (0.01 kWh) – 70cm: working on a laptop for one hour (0.07 kWh) – 1.5m: playing on a game console for one hour (0.15 kWh) 2 – 2m: blow-drying hair for 10 minutes (0.2 kWh) – 2.5m: cooking half a kilo of potatoes with the lid on the pan (electric cooker) (0.25 kWh) – 5m: cooking half a kilo of potatoes without the lid on the pan (electric cooker) (0.5 kWh) – 6m: baking a frozen pizza in the oven (0.6 kWh)
Opening
→ How is energy generated/produced? Which examples do you know from your countries / region? When we speak of energy, we are not only speaking about electricity, but also about the energy needed for heating and transportation. The participants name the different sources of energy, e.g. on a poster, if necessary, with the help of the workshop leader. The main sources of energy are • nuclear energy • biomass (e.g. wood, plants) • natural gas • geothermal energy
1 Unless specified otherwise, all details are based on average values determined according to the average estimated electrical output (watts) of current reference devices. 2 Cf. https://www.klimaaktiv.at/energiesparen/effiziente_geraete/neue-Konsolen-Stromverbrauch.html [last accessed on 12 December 2022] (in German)
