Setting the air conditioner at a lower temperature cools down the house more quickly?
The burst of heat you experience when you get home may lead you into temptation but unfortunately you will not speed up the process.
The consumption peak of a bulb when it is switched on is not so significant to justify leaving it on, even if it is only for a few minutes. There is one exception to this rule: fluorescent bulbs do not last as long if you switch them on and off repeatedly.
In short:
Fluorescent lights: if you are only nipping out, you should leave them on, since these bulbs "suffer" each time they are switched on. If the light bulb blows, the cost of buying a new one is greater than the energy you would save.
Halogen and LED lights: these do not “suffer” when you turn them on; therefore it is always advisable to switch them off, even if you are just nipping out.
