The surprising link between things that make us happy and things that save energy



By Chris Mooney December 19 

If you go to a life coach or therapist seeking to improve your happiness and personal sense of well-being, you're likely to hear some pretty familiar advice.

Sleep more. Spend more time with friends. Exercise more. Find a hobby. Volunteer. Give something back to the community.

Most of us have heard all of this before. But you might be surprised to learn that these "New Year's Resolution" style life changes have a major additional benefit: Spend more time doing them, and you may also dramatically cut your energy use -- and electricity bills.

That's the upshot of new research by Joseph Kantenbacher, a Ph.D. candidate at the University of California-Berkeley whose dissertation research was presented earlier this month at the annual Behavior, Energy, and Climate Change conference in Washington, D.C. The insight on the relationship between happiness-inducing activities and energy savings arose when Kantenbacher analyzed how people actually use their time when they’re not working -- and then identified which of these non-work activities tend to use a lot of energy (per unit of time), and which activities tend to use very little.

The result was this highly revealing figure, which plots how much energy, per hour, various non-work activities burn up. Energy use is divided into three types -- travel energy (gasoline, jet fuel, etc.), household energy (electricity, gas, and so on), and finally "embedded energy," which refers to the amount of energy required to make a particular object, like growing and then processing a piece of food, that is then consumed or used in a particular activity, like eating:
