Do the star ratings and logos on the appliances clearly speak for them to be eco-friendly? Nope, the raw material of which the appliances are composed of decide their functioning and sustainability.

The reduced amount of energy this refrigerator demands is able to save one whole power station. That’s pretty cool!
