If you cut back on your energy usage, you will be a happier person -- and not just because of all the money you'll save on your electricity bill. It turns out many of the activities that make people happier, like sleeping and socializing, are those that involve little or no household energy. That's according to a study released by the University of California at Berkeley that found that a blissful lifestyle is perfectly congruent with a low carbon footprint.

"A number of the least energy intensive activities that I found -- sleeping, socializing, hobbies, and so forth -- are enriching personally," study author John Kantenbacher told the Washington Post. "So they make people happy to do them, but they also are relatively low consuming activities."

The report breaks down five of the most beneficial activities and how they help save energy:

So the next time someone asks you why you are so happy, just smile and tell them it's because of your energy-efficient lifestyle.

You've done everything you can to conserve energy in your house -- purchased the latest Energy Star appliances, insulated your walls, and turned your thermostat down to 68. But the next thing you know, your kids are leaving lights on in rooms they aren't occupying. Or staring into the refrigerator for minutes on end while all the cold air escapes through the open door. Or nudging the thermostat higher when you aren't looking. How can you convince your kids to help, not hinder, your efforts to cut down on energy usage?

Knowledge is Power

Your children can't make the effort to save energy if they don't know how. Help them start building good habits early, and make sure they’re aware of simple ways they can help lower the utility bills:

To save electricity:

To conserve water:

To keep your heating and cooling bills low:

What if They Don't Wanna?

Of course, every parent knows that telling your kid to do something doesn't mean it's going to happen. The trick is to get them to buy in. While one reason to conserve energy is to save money on your utility bills, children have a habit of taking mom and dad's money for granted, so that might not be your most persuasive argument.

Instead, try teaching them about how human reliance on fossil fuels is harmful to the environment -- but they can help make a difference. If your children have particular interests, like animals, you can tie the themes together -- tell them they can help protect animal habitats by doing their part to conserve energy.

Another trick is to give them a green light to correct you if you make a mistake like leaving the water running. That gives the kid some fun responsibility, and encourages them to be vigilant about your behavior -- which increases the likelihood they will be about their own.

And remember, the best way to teach your kids how to conserve is to set a good example by doing it yourself.

If you’re a busy person, constantly running from one place to another, it can be easy to forget some of the little things you leave behind at home. The thermostat, for example, controls perhaps the two biggest energy hogs in your home, the air conditioning and thermostats help improve your home comfort by offering advanced temperature and climate features as well as remote control that simply cannot be beat. Chances are, you are one of many Americans who uses a smart phone, tablet, or computer with internet access every day. A Nest thermostat learns your preferences for daily operation, but can still be controlled from far away if your plans change throughout the day! Here’s a bit more on those features.
