• Remember that insulation may seem expensive at first but if you're a homeowner it's going to save you a boatload of money in the long run and increase the value of your home.
• Having a clean and uncluttered attic means that the air can flow more easily which will also reduce the cost of cooling during the summer.
• Want to cut the cost of refrigerating your food? Consider thinking of refrigeration through the lens of thermodynamics. Chest fridges that open from the top let out very little cold air when you open them because cold air drops and warm air rises. Every time you open an upright fridge, you're letting out all that cold air you paid via your electrical bill to make. Check this out:

• Instead of spending lots of money on an air freshener or filter, consider buying a few houseplants. A few strategically placed Feston Rose plants or some Devil's Ivy can serve to remove common pollutants and will leave your house smelling fresh and clean without having to spray chemicals everywhere or replace hepa filters every year.
• If you're having trouble with pests invading your garden and aren't interested in using chemicals, consider trying to attract local predators to deal with them. Cats deal with mice and small rodents, and many kinds of birds deal with insects. All you really need is to put out milk now and again or put in a bird bath and feeder.
