Over the years I've pretty much done the usual energy savings with low hanging fruit like energy efficient appliances and lights but never realized how much I was still losing through air leaks. After talking to some of my neighbors I realized I was way ahead of them with much lower utility bills. Four have ended up going with solar to drop their ultra high utility bills. I have a 1660 sqft split level home built in 1960 that the previous owners had done very little weatherization, to cut their utility bills. Last year I spent a total of $705 on electricity and $687 for gas and after two days of watching Youtube videos I know I could do much better. I'm hoping for $200 a year off both the electric and gas bills. The biggest hit I take is for cooling four months in the summer and for heating four months in the winter. If you haven't spent much time on Youtube your missing out on some great information of making your home much more energy efficient. The two biggies that I ran across that had me shaking my head that I had no knowledge of. Attic air sealing, and the especially insulating the rim joists in the basement. With the Attic I figured you just have to add more insulation, Nada you have air seal first or you're just wasting your money on the additional insulation. Feel free to add more videos and information as needed to this thread.
