- Change the regular light bulbs to compact florescent bulbs. They have a higher initial cost but last longer and use less energy. Remember to dispose of them properly when they burn out; they contain mercury.
- Use dimmers on regular lights when possible.
- During the day, open window shades, blinds and curtains to let in natural light rather than turning on lights in the apartment.
- Light some candles (but never leave them unattended).
- Turn off lights when not in use or before you leave the apartment.
