what is the average cost of fluorescent lights and incandescent lights?

Question

What is the average cost of a 13 watt fluorescent light and a 60 watt incandescent light in canada and how much do you save every year if you use a fluorescent light(average)?

Answer 1

In light output a13W fluorescent is about the same as a 60 watt incandescent lighbulb. The difference is 47 Watts.

If it burns 4 hours a day for 350 days per year we have

E=47 x 4 x 350=65,800 kWh
Let a 1 KWh= $.15

then annual savings are
$=65,800 kWh $.15 /KHh=$9.87
