Saving Energy
Energy Saving Tips:
- Unplug: Even when a charger is not connected to the appliance, it still
consumes electricity.
- Switch off: Do not leave appliances on standby. Use the „on - off“
function.
- Only boil as much water as you need: Avoid boiling water
unnecessarily.
- Use energy-saving-bulbs: Energy-saving bulbs can reduce your
lighting costs and avoid CO2 emissions.
- New devices: More energy efficiency at home reduces energy
consumption.
- Don´t use the dryer: Put the clothes on the clothesline.
