Oven
- Use ceramic or glass containers if possible, as these allow cooking at temperatures around 25 °C lower;
- Open the oven only when necessary;
- Each time you open the oven door this causes an energy loss of at least 20 %;
- Make the most of your capacity by cooking the largest number of foods at once;
- Avoid preheating, especially if cooking for over 1 hour;
- Turn off the oven a little before cooking ends: the residual heat will be enough to finish cooking;
- Choose an oven with internal ventilation because they distribute heat better;
- Keep the oven clean so that the heat reflects better, consuming less energy;
- Check and clean the joints and rubber seals whenever necessary;
- Adjust the temperature to the lowest possible:
- Lowering the temperature from 250 °C to 200 °C results in a 37 % energy saving.
