Unscrew Around

Even though things may look a bit bare (I prefer to think of it as "minimalist"), you can cut your energy consumption significantly—and save up to $90 in electricity costs, as well as the costs of bulb replacement—by disabling half of the bulbs in multibulb light fixtures.

You will conserve an estimated 875 kilowatt-hours of energy by eliminating 10 60-watt bulbs that are normally on for an average of four hours per day. But be sure to leave enough illumination so that your eyes aren't strained.
