Since the advent of the incandescent (and even before), quality of light has been on the tip of everyone’s tongue. Regrettably, that quality has mostly been unfortunate. When incandescent lights were the only choice, the early 20th century population complained about the glare and the possible dangers of electricity.

Case in point: on an episode of Downton Abbey (Masterpiece’s smash hit about an elite family living on an estate in the early 1900’s), the prim and hilarious Dowager Countess laments the new electric lamps:

“Such a glare! I couldn’t have electricity in the house – I wouldn’t sleep a wink. All those vapors seeping about. Feels as if  I were on stage at the Gaiety.”

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.
