Computers and other home electronic equipment represent one of the fastest growing areas of home energy use. Our toys and tools keep several large power plants in business.

Liquid crystal displays are an example of how new technology can decrease our energy use. They are much more efficient than standard monitors and TVs.

A considerable part of a device's energy use is when it is in active standby mode, such as when a computer or stereo waits for a click of a button to begin operating. This is also energy used for clocks and display lighting.
