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.
