Q. Does one have to make Teshuva during Yom Kippur for a sin commonly committed, namely leaving the light on when not needed, as when someone leaves home during the day and no one stays there, since one transgresses on the prohibition of Ba’al Tashchis, (destroying or wasting usable items)?

A. Horav Shlomo Miller’s Shlit’a opinion is that although there is reason to turn off lights when not needed at all even for security, one should avoid creating a fight with a spouse or child and similar for that reason.

The Rov Shlit’a also mentioned, to consider what would the saved amounts be used for, if at all.
