Companies Waste $2.8 Billion Per Year Powering Unused PCs
snydeq writes "Unused PCs — computers that are powered on but not in use — are expected to emit approximately 20 million tons of CO2 this year, roughly equivalent to the impact of 4 million cars, according to report by 1E and the Alliance to Save Energy. All told, US organizations will waste $2.8 billion to power 108 million unused machines this year. The notion that power used turning on PCs negates any benefits of turning them off has been discussed recently as one of five PC power myths. By turning off unused machines and practicing proper PC power management, companies stand to save more than $36 per desktop PC per year."
Power usage generally peaks in the afternoon
What did you expect? Everyone is forced to live according to the same schedule, i.e. work 9-5 on weekdays, sleep at night, etc.
as coal power is cheaper, they try to get as much as possible from the coal.
Until the planet runs out of coal, that is. Which will happen, whatever you do, sooner or later. In the long term, being "carbon neutral" is either meaningless, or means you're replanting the forests you (the western culture) cut down.
