Turn off your screen saver! Did you know the EPA estimates that using a computer's "sleep mode" reduces its energy consumption by 60 to 70 percent? If "sleep mode" was used with all computers, enough electricity could be saved each year to power Vermont, New Hampshire and Maine, while cutting electric bills by $2 billion, and reducing carbon dioxide emissions by the equivalent of 5 million cars. A screen saver that displays moving images causes your monitor to consume as much electricity as it does in active use. A blank screen saver is only slightly better but that reduces energy consumption by a small amount.
