Nokia has issued a press release asking users to unplug chargers when they are not in use. Apparently this can save enough electricity to power 85,000 homes a year. New Nokia phones will remind users to unplug their phone chargers as soon as the battery is charged. 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."
