Innovation: Monitoring costs

Most PC users leave their computers on all day even when they are not using them, generating heat and glare and wasting electricity. Nighthawk Electronics has developed a monitor that turns the screen off when it is not in use, typically saving about pounds 50 a year in electricity. The monitor switches off the screen when the keyboard has been inactive for a pre-set period. As soon as the keyboard is touched, the screen comes on again.
