Answer :
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

100 watts = 100 joules per second
22 watts = 22 joules per second
Saving = 78 joules per second
1 hour = 3,600 seconds
24 hours = 86,400 seconds
(78 joules/sec) x (86,400 sec) = 6,739,200 joules
22 watts = 22 joules per second
Saving = 78 joules per second
1 hour = 3,600 seconds
24 hours = 86,400 seconds
(78 joules/sec) x (86,400 sec) = 6,739,200 joules
