Most of us are comfortable with incandescent bulbs - you know, the classic light bulb shape that emits warm, orange-y light. However, they are big energy wasters when compared with CFLs or LEDs, new lighting options that are the result of great advances in science and technology. But don't forget the most basic, cheapest and most efficient of all lighting sources - the sun.
Weigh your options and determine which lighting sources work best for your home. And remember: the most successful, energy efficient lighting schemes combine several of these sources.
1. Compact Fluorescent Lamps (CFLs)

Fluorescent lighting carries a certain stigma. If you think it's not appropriate to light your home, think again. CFLs will save on energy without creating an unflattering atmosphere.
2. Light Emitting Diodes (LEDs)

3. Natural Light

Yes, it's so obvious it almost feels like cheating to mention the sun within a list of energy efficient lighting options. But it is the very first and very best of the sources. Utilize passive design techniques to capture as much sunlight as possible to light and heat your home.
4. Sun Tubes

Have a room with no access to natural light? When windows or skylights aren't an option, consider installing a sun tube to cut your lighting costs.
