Use the fan-oven setting when the recipe allows

Why this can help
Circulating hot air can allow suitable oven recipes to cook efficiently at an appropriate lower setting. German environmental guidance recommends considering fan-assisted cooking.
One possible next step
Check whether a familiar recipe gives a fan-oven option and use that setting correctly.
What changes the outcome
Follow the recipe and appliance instructions for temperature and time. This does not mean skipping required preheating or complete cooking; measure equivalent cycles before claiming an energy saving.
Your illustrative scenario
Over one year · with the assumptions below
You
20 kilowatt-hours of electricity less
You + 10 friends
220 kilowatt-hours of electricity less
1,000 participants
20,000 kilowatt-hours of electricity less
These are scenarios, not measured personal or collective savings. One separate household per participant. People sharing a home count it once, not once each.
Your inputs
- Electricity per complete cooking cycle Before
- 0.8 kWh
- Electricity per complete cooking cycle After
- 0.6 kWh
- Comparable occasions per year
- 100
Calculation of the difference: (0.8 − 0.6) × 100 = 20 kilowatt-hours of electricity
Calculation boundaries
Compare the same appliance service and a complete cycle, including any extra cooling, reheating, spinning or finishing. Only electricity is counted, not manufacture or carbon emissions. This scenario applies to electrical appliances; do not enter gas or biomass as electricity. Keep the same food quantity, cooking result and food-safety requirements. Follow the recipe and appliance instructions for temperature and time. This does not mean skipping required preheating or complete cooking; measure equivalent cycles before claiming an energy saving.
The initial values are editable arithmetic examples, not measurements or typical savings from the cited studies. Replace them with comparable readings for your situation. The sources support the mechanism and its conditions; they do not predict these numbers.
