3. Insulate your attic (if you have one)
If you’re living in a big house that also has an attic and you don’t really use it for anything else than to deposit stuff that you don’t use anymore, you might want to reconsider its usage. In most cases, an attic that is not properly insulated allows the heat to go out of the house much more easily. By insulating your attic, you will have a warmer house during the cold season and a cooler one during the summer.
Plus, the heating bills are super small! Isn’t this an ideal situation? You can save the money for that amazing vacation you’ve been dreaming of instead of throwing it away on expensive bills.
