Question
Suppose it's winter and very cold outside. You plan to leave your house for several hours. Your neighbor says it would use less energy to turn your heat off while you arc gone, and turn it back on when you return home. Your uncle tells you that the way to use less energy is to leave the heat on while you are gone. (He says that if you turn it off you will use more total energy heating the house back up when you return home.) This is a hotly debated issue for some. Strictly as far as energy conservation is concerned, who's correct Why Conservation isn't necessarily everything. What are some legitimate reasons that you might make the choice that uses more energyExplanation / Answer
The uncle comment is correct.
If you didnt turn the heater on, once you come back after several hours, the room might be cold as that of the atmosphere outside. The one who went outside is also very cold. To make him and the room hot the heater will take large enough of energy in the form of temperature. Large energy is required for the heater.
If suppose the heater is on, while coming back also it is hot enough. It works as normal only.
The same thing we can think in an opposite way by considering the operation of an Air Condition( A.C). If we didnt turn the A.C on while going out it will take large enough energy to make the room cool enough.
Large Heat flow from sorrounding.
Efficiency of device
are some of the reasons
