Abstract

An energy saving device that has an electrical inlet which connects to a general power outlet, and has at least one monitored electrical outlet connecting to a computing device, the energy saving device having at least one switched electrical outlet which connects to, and supplies electrical power to, at least one peripheral device, which in a preferred embodiment is a computer monitor. The energy saving device includes a switch to control electrical connection of the inlet to the switched electrical outlet, and thus to control supply of electric power to the peripheral devices. Other peripherals may include printers, speakers and desk lamps.

Claims
