Incandescent light bulbs need to go in trash today

Light-emitting diode (LED) bulbs, center, are the way to go, says a UC Berkeley energy economist. Now is the time to r eplace all your incandescent bulbs , left. And replace your compact fluorescent light (CFL) bulbs, right, when they burn out. A standard LED bulb now costs only $3-$4, less if your local utility subsidizes them. That LED uses 8.5 watts to produce the same amount of light as a 60-watt incandescent. The Department of Energy generally calculates costs assuming a lightbulb is used three hours per day, but let’s be super conservative and assume it’s on only one hour a day.
