EU sets energy efficiency requirements for external power supplies
The European Commission has adopted a new regulation to improve the energy performance of external power supplies. The regulation comes into force in two step in 2010 and 2011. It is expected to cut the supplies' electricity losses by nearly a third by 2020.
The external power supplies convert power input from the mains power source into lower voltage output for household and office products such as mobile and cordless phones, notebook computers, modems etc.
The requirements correspond to internationally recognized efficiency criteria, which are achieved by models with significantly enhanced efficiency compared to a current average model.
The requirements address both the "active" efficiency, i.e. the efficiency when power is supplied to for example a notebook when being actually used, and the "no-load" power consumption, i.e. the power which the supply still uses when for instance the notebook is not plugged in.
"Setting ambitious energy performance requirements for products is an important contribution to improving Europe's energy efficiency," said Energy Commissioner Andris Piebalgs.
The resulting savings of 9 terawatt hours (TWh) is enough to power Lithuania for a year and will reduce annual CO2 emissions by more than three million tonnes.
