“Most energy use in personal computers takes place when no one is there,” says Bruce Nordman, a researcher in the Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory (Berkeley Lab). Summing up what many probably intuit but don’t think much about, PCs are fully on and using considerable energy even if they are idle. This is also true of game consoles and set-top boxes. And this is wasted energy. Sleep modes that... Read More
