I think the title of this post tells you all. If you are using old household appliances (e.g. refrigerator, washing machine, dishwasher…) do consider buying new ones with energy sign A or A+. Old machines (5 or more years old) have no energy sign at all or have energy sign C or D … those machines are bad machines swallowing energy with big spoon. Important: Don’t throw old machines anywhere!!
Impact: reduce electricity consumption, reduce energy bill, and reduce pollution
