Utilities are a HUGE issue for us. I dont like to freeze my kids out so there is only so low I will take my heat (nat. gas) but I really need to bring down costs. So here is what I have planned so far we live in a largish (3300 sq ft) 40 year old house. we replaced 3 of teh upstairs windows last year and that did help but we have 11 more to do that are original. 2 for sure have to go this year the seal is gone ( they get moisture between them). For now though we have purchased heavy drapes for all windows so that helps keep the heat in. We are replacing our old wooden front door. It is COLD! You can put your hand next to it and feel the cold. We are ordering a steel door that is energy star, and putting a storm door on it. It also has single pane windows for the side lights so that all has to go. We watch how many lights we have on and have greatly reduced our water usage. What are some other ideas of what we can do? Would you like to join me in this quest?
