The BBC reports on the cost of not shutting computers off when not in use – “”Most people could easily save “£100 a year and a small-to-medium sized company should easily cut “£5,000 off its bills just by following our advice,” said Mr Ross.” For those of us in the US, that’s $9170. Our Middle School had a big lights off and computer off campaign a year or so ago, and saved over $10,000. Not bad for a few seconds of work each day.
