Green.view: Can the spam
According to a report from an environmental consultancy, ICF International, commissioned by McAfee, a computer-security company, some 62 trillion unsolicited e-mails were sent in 2008, using 33 terawatt hours of electricity. That is equivalent to the energy consumed by 1.5m American homes or 3.1m cars over a year. If generated by coal-fired power stations it would release 17m tonnes of carbon dioxide, some 0.2% of global emissions of this greenhouse gas.
