You replace a 100 w incandescent lightbulb with a 22 w cfl bulb. if you leave your lights on 24 hours a day, how much energy are you saving each day by replacing this bulb?

We need to first consider the power saved.

Energy saved = 100W - 22W

Energy saved = 78Watts

We need to first consider the power saved.

Energy saved = 100W - 22W

Energy saved = 78Watts

This means that you are saving 78 Watts of power each day.

This means that you are saving 78 Watts of power each day.

Since the bulb is on for 24 hours, the energy saved in joules per second is expressed as;

Energy saved = 78 × 86,400secs

Energy saved = 6,739,200Joules

Hence the energy saved if the bulb is on all day is 6,739,200Joules per seconds
