Living with a friend or family member may seem like it use more resources, but two people sharing a space reduces household energy by about 18% per capita. The savings shouldn't stop there. Two heads are in indeed greener than one. That's why you should hold a house meeting on ways to reduce energy use.

If your household is already one that has weekly or monthly meetings, than putting a discussion of water and energy use on the docket won?t be so difficult. But if this is a new thing for your roomies, you'll probably have to finagle your roommates and/or family members into showing up. Tell them it's a meeting about saving money. And don't forget to provide eco-friendly snacks for all.

What to Discuss and How to Discuss It

Talk with your family about tactics and techniques that can save money, energy and water. For example, you can ask that people turn off the lights when they leave the room. Talk about which rooms aren't used often. You can install motion sensors in those rooms to keep lights from being left on for days.
