Did you know that the lightbulb on the left (a filament bulb) has not changed since we were kids...that's a long time to not change in a very changing world. Apparently technology on lightbulbs just stood still since they worked. Suddenly some smart environmentalist decided that this lightbulb burned up more energy than was practical so now we have a new lightbulb....the one on the right is called a CFL and is supposed to burn cheaper and longer and is not harmful to the environment. We've changed all our lightbulbs to CFLs...check around your house and see if you still have "old style" bulbs...you need to get those changed! SAVE THE PLANET one little light bulb at a time!
