Choose LED holiday lights when decorating the tree or around the house. LEDs (which stands for "light emitting diodes") last up to 20 years and use only one-tenth the energy of traditional Christmas lights. While they may cost a bit more, the energy and lifetime-use savings will more than pay for the investment. Added bonus: LED lights do not get warm, which makes them a safer alternative for children, since they're cool to the touch.
