Reduced cooling demands makes it easier to quiet a computer. Lower energy consumption can also make it less costly to run, and reduce the environmental impact of powering the computer (see green computing). If installed where there is limited climate control, a lower power computer will operate at a lower temperature, which may make it more ...
The label must show the model number, the size, key features, and display largely a graph showing the annual operating cost in range with similar models, and the estimated yearly energy cost. [2] [3] Appliance energy labeling was mandated by the Energy Policy and Conservation Act of 1975, which directed the Federal Trade Commission to "develop ...
Both dynamic and short-circuit power consumption are dependent on the clock frequency, while the leakage current is dependent on the CPU supply voltage. It has been shown that the energy consumption of a program shows convex energy behavior, meaning that there exists an optimal CPU frequency at which energy consumption is minimal for the work done.
The label comprises an energy consumption figure for the appliance and a star rating. The energy consumption figure is an estimate of how much energy (in kilowatt-hours or kWh) the appliance will use over a year, based on assumptions about "average usage". However, actual energy consumption will depend on how an appliance is used and how often ...
Power management is a feature of some electrical appliances, especially copiers, computers, computer CPUs, computer GPUs and computer peripherals such as monitors and printers, that turns off the power or switches the system to a low-power state when inactive.
This can be avoided by unplugging the appliance or using a power strip and using the switch on the power strip to cut all power to the appliance." [3] Standby power used by older devices can be as high as 10–15 W per device, [4] while a modern HD LCD television may use less than 1 W in standby mode. Some appliances use no energy when turned off.

The energy consumption of consumer electronics increases – in America and Europe – to about 50% of household consumption if the term is redefined to include home appliances such as refrigerators, dryers, clothes washers and dishwashers.
