스팸메일

정말 엄청난 숫자구나. 스팸 패일 지우는 데 짜증이 나긴했지만

그걸로 인해 발생하는 현실적인 금전적 돈 문제까진 생각은 못했봤었는 데

역시나 남다른 미국 사람이 이에대한 조사를했었고

스팸 메일로 인해 발생하는돈 손실만 한해에 30억불로 우리 돈으로 4조5천억원이다.

지난 밤에 사용하다가 깜빡하여 꺼지 않고 켜놓은 채 잠들기에 발생하는

전기료가 28억불이라 한다.

이 스팸메일에 전기료만 계산된 것이지 이를 걸러내는 디바이스에 투자 한 돈은

계산하지 아니 한 것이라하니 이들 모두를 계산하면 이 도한 엄청난 숫자가 될 것이라하며

그래도 다행인 것이 오늘날의 수준으로 스팸메일을 걸러낼 때

온실가스를 시간당 1350억 킬로 왔트 줄일 수 있게되었다하며

이 온실가스의 양은 310만대의 승용차가 20억 갤론을 사용할 때 나오는 양과 동일하다고

Spam costs $3 billion a year in wasted electricity alone

My previous blog post on the hidden costs of computing -- which pointed to a study that said that leaving computers on overnight wasted $2.8 billion of electricity a year -- was hotly contested by readers, many of whom felt the time spent rebooting their computer every morning was a far greater waste of money.

That remains open for debate, but here's a statistic that I think everyone can get behind: Spam wastes even more electricity than leaving your computer running 24/7, costing roughly $3 billion a year in wasted power alone.

McAfee calculated that sending, routing, and otherwise dealing with spam eats up a total of 33 billion kilowatt-hours of electricity each year. As The Guardian notes, that's enough to power 2.4 million American homes and, by my math (as the average kw-hr costs about a dime), a total cost of over $3 billion.

And that doesn't even take into account money spent on spam filtering software, the loss of productivity due to users spending time deleting spam messages and finding false positives, and losses from people who get caught up in spam-based scams, either purchasing useless or undelivered products or being the victims of a spam-based crime.

The additional insights in McAfee's Carbon Footprint of Spam Report (registration required) suggest that spam transmission creates the same amount of greenhouse gas emissions as 3.1 million passenger cars using two billion gallons of gasoline each year. That's shocking.

But all is not lost: The good news is that McAfee notes that current levels of spam filtering save 135 billion killowatt-hours of electricity that would otherwise be wasted if all users and computers went unprotected from spam.
