With newer automobiles allowing you to plug electronics into outlets and USB ports, our cars are becoming mobile offices for our everyday lives. But when you reach your destination, be sure to unplug your GPS devices, phone cords and whatever else you might have plugged in. Even with the car turned off, many of these items will still pull power from your car's battery. This can wear down the lifespan of the battery and also wear down electronic devices and cable cords. And if you're driving in your own community, where you know the roads without the assistance of a GPS device, just unplug entirely and stash it until you really need it.

Using special insulated window drapes at home is an easy (and decorative) way to reduce heating costs in the winter, since they block cold drafts. But going to the store to buy new drapes can be a pricey investment. If you have window drapes already, here's an easy way to DIY your way to insulating drapes. Simply take sheets of bubble wrap and pin them to the reverse side of the drape panels (so the bubble wrap faces the window). The small air bubbles act like mini-greenhouses and double the insulation value of the drape panels without ruining their decorative look.

If you want to save a ton of water and energy, do this one thing: Wear your jeans more than once before washing them. Some of the most laundered items at home are denim jeans, and while they can be soft and cozy, they also can be heavy and bulky in the washing machine. The United Nations Environment Programme actually came out with a study that said if you wear your jeans at least three times before washing them, you can save five times the energy from your washer and dryer use. Add using only cold water and skipping the drying cycle, and you'll see a significant savings over time.
