Whether it is in the home or the office, energy-efficient devices help to save electricity and thus costs. Although the EU energy label is now available for many larger electrical appliances such as fridges, washing machines or dishwashers, this label does not cover a lot of smaller household devices. The Blue Angel environmental label is used to indicate energy-saving kettles, coffee machines and hair dryers. Alongside energy efficiency, these appliances must also comply, however, with many other requirements e.g. they need to have particularly low noise emissions or low pollutant emissions, as well as being easy to repair and recycle and delivering good performance characteristics.
