9. Energy Efficient Light Bulbs

Florescent light bulbs are now available in most sizes and shapes. They cost more to purchase but save a lot of energy and last much longer than incandescent bulbs. One drawback - florescent light bulbs require special disposal methods.

Light Emitting Diode light bulbs are now reaching the market. In addition to using less energy and lasting for a very long time, they produce little heat and thus make for ideal lighting in refrigerators and freezers and reduce summer cooling needs.
