Sleep Mode Helps Schools Save $50 per Computer

Via this program, US secondary schools, colleges and universities are on track to save $40 million dollars per school year, says the EPA.

Since 2012, schools have been taking steps to enable software features that automatically put inactive computers and monitors into a low-power sleep mode, saving up to $50 per computer annually. In prior years, this presented a technological challenge to many schools, since older software applications often undermined low-power capabilities. But software has improved and with declining school budgets, the computer power management (CPM) opportunity has attracted over 680 academic institutions, with over two million computers.

However, this success represents only a fraction of the estimated 61,000 schools in the US, says the EPA.

An International Energy Agency report, “More Data, Less Energy: Making Network Standby More Efficient in Billions of Connected Devices,” finds that in 2013, the world’s networked devices consumed around 616 TWh of electricity, the majority of which was used in standby mode. Of that total, around 400 TWh was wasted because of inefficient technology.
