We’re all looking for ways to save money, and if we can do that while also saving the Earth, everybody wins. So here are a few tips to reduce your utility bills as well as save money and resources.

Switch as many light bulbs as you can to compact fluorescent (CFL) bulbs – they take a fraction of the power and last forever. You may want to keep traditional incandescent bulbs in some areas (like the dining room), but the more you can swap the better.

On that note, turn off the lights when you leave a room. Forgetting to turn off the lights in an unoccupied room wastes a lot of electricity and money! The same goes for televisions and computers. A quick flip of the switch can take dollars off your electric bill.

If you pay for heat, insulate your windows in the winter with plastic sheeting—this will keep more warm air inside the house. In the summertime, try to only use your air conditioner in an emergency, and use fans and open windows to maintain cross breezes for natural cooling as much as you can.
