New research from anti-virus gurus McAfee shows that spam email – which accounts for 80 per cent of the world’s email traffic – uses as much electricity as 2.1 million US homes; over 33bn kilowatt-hours of electricity.
The report estimates that 62 trillion spam messages were sent last year. The energy involved in creating and deleting these unwanted emails accumulates to the emission levels generated by 3.1 million cars.
“As the world faces the growing problem of climate change, this study highlights that spam has an immense financial, personal and environmental impact,” said Jeff Green, a senior vice-president at McAfee.
The McAfee research comes as a rival online security group, Symantec, shows a 192 per cent increase in spam email. It is thought 90 per cent of these messages are generated by 'bot networks'; computers which have been hijacked and then programmed to relay and send spam emails without the owner’s knowledge or consent.
