Rohm Circuit Kills Vampire Power, Pulls No Electricity On Standby

Japanese semiconductor maker Rohm is looking to vanquish vampire power, the energy wasted by tech on stand-by, with its new LSI circuits. The circuits consume no electricity even when in stand-by mode, allowing for a quick power up without the power drain. Considering that roughly 10% of a house’s energy bill goes to these silent suckers, Rohm’s circuits could save money and the planet at the same time.

Rohm estimates that around 15 billion kilowatt hours of electricity, roughly the output capacity of two nuclear reactors, are consumed every year in Japan by devices on standby. In the U.S., vampire power is estimated to cost consumers US$3 billion annually.

Experiments have already shown that an average game console could cut its power use by roughly 70% if it adopts circuits incorporating the new technology—exciting news for people like me, who tend to forget to power off their Wiis at night. Rohm says it’ll start producing the circuits on a commercial basis within a year or so. [Japan Today]
