Incandescent lightbulb
VS
Energy efficient lightbulb

2. • One day, the old
Incandescent
lightbulb met his
great grandson,
the Energy
Efficient lightbulb.

3. My dear, how are you these days?
Are you still trying to take my
place in people’s houses?
Of course, I have many reasons to
do that, and you know them, too.

4. Reasons?…All I know is you are very
expensive and and I can’t understand
the adjective “economic” in your case.
Yes, but in your case only 10% of
energy consumed is given off as
light the rest, 90%, is heat.

5. You are right, but that gives my
light a nice heat, a pleasant
golden colour…
Not all people like hot light, some
of them prefer white, cold light.

6. Let me tell you something more…you
are so long! You don’t match any
lighting element.
Maybe, but I don’t explode in
contact with a drop of water, as
you do very often

7. My life span is longer and people save money
and effort changing lighbulbs less often. And
don’t forget about the energy costs!
Really? I’m not so good at
Maths, have you made some
calculation?

8. I kept the best at the end. I am substantially more
environmentally friendly than you, which consume far more
electricity -- the dominant environmental impact. Switching
away from incandescent reduces the environmental harm of
lighting by three to 10 times.

9. Ok, my dear great grandson…you convinced me. It is
time for my retirement. I am sure we’ll be hanging
around for a while more, but the future is yours! Be
brave, be bold and save the environment!
