14. Rethink your home’s heating system
This tip is a big-ticket item. But it can save you big bucks, too. Take some time to research how efficient and costly your home’s current heating system is and how much you might save by switching. In general, natural gas heating costs much less than oil heating, with the Department of Energy estimating that the average person spent more than $700 (annually, presumably) heating a home between 2007 and 2012, and more than $1,700 heating one with oil. Propane and electric baseboard heating systems tend to cost even more. Consider switching to a more efficient and less costly heating system.
