As part of an announcement by Nokia regarding new green initiatives and features for future phones, the company revealed a little-known fact about mobile phone adapters:

Kirsi Sormunen, Vice-President of Environmental Affairs at Nokia said, “Around two-thirds of the energy used by a mobile phone is lost when it is unplugged after charging but the charger itself is left in a live socket. We want to reduce this waste and are working on reducing to an absolute minimum the amount of energy our chargers use. The new alerts also play an important role, encouraging people to help us in this goal by unplugging their chargers.”

So as the plugged-in charger for my T-mobile Dash is sucking valuable energy from the Seattle grid, I wonder why none of these mobile companies have told us about this. They don’t have space within the instruction manual for this little factoid? Sheesh.

Grist thanks its sponsors. Become one.
