These have relatively low energy consumption and low energy 'sleep modes', which reduce power consumption when the equipment has not been used for a specified period of time. Laptop computers use around one-tenth as much energy as desktop computers, while inkjet printers use less energy than most types of laser printers. Computer monitors can consume 50 to 90 watts of power. Energy Star' monitors also have 'sleep' modes. Some models can be used with existing computers if suitable software is installed.
Smaller screens tend to use less energy.
Soon, energy-efficient liquid crystal displays will replace standard monitors in many applications. Most office equipment consumes most of its total energy when on standby or idling. Select equipment with the lowest standby power consumption. Use the double-sided copying capability of photocopiers and printers to cut paper consumption. Copiers and printers should be designed to use recycled paper without voiding the warranty.
