Leafy Green Feedback

People these days are looking to conserve energy for a wide variety of reasons - financial, environmental, concern about dependence on foreign oil, generic anti-wastefulness, or (let's face it) just because it's what everyone else is doing. But it can be really hard for would-be conservers to make informed decisions on how to save if they don't know where their energy is being spent. That bill at the end of the month doesn't contain a whole lot of information, and that's a problem.

It all comes down to granularity, or the resolution of the information we receive about our use. A utility bill at the end of the month is very low-resolution, low-granularity - it's whole-home usage over the course of an entire month. We can't see which days we use more (weekends? weekdays?), which times we use more (probably evenings?), which appliances use more (TVs? Dryers? Refrigerators?). I dunno, do you?

Without this information, it's hard to know where to cut back, and psychology researchers have known this for a long time. Many studies have been conducted in which people are given more granular feedback on their energy use - daily, hourly, or even real-time - and oh, the savings, how they pile up. In a study by Petersen et al. at Oberlin college (2007), the authors set up an energy-saving competition among the dorms. All of the dorm residents had access to energy feedback (which was already an improvement for them, since dorm residents don't pay their energy bills, and so never see any information on energy use). Some of the residents were given their data on a weekly basis, while others could access their real-time energy use data online. The real shocker of this study, to me, was how much all of the dorms saved - even the low-resolution dorms showed a 31% drop in energy usage, particularly impressive because dorm residents have no control over their thermostats. But this saving shot up to an almost unbelievable 55% for the high-resolution dorms. These savings are on the high end, but in every study I'm aware of, the finding is the same: Feedback leads to conservation.

Clearly, there's a lot to this granularity thing. Can you imagine what it would be like if we could all see our own home's real-time energy use, or even better, see it at the level of an individual room or even appliance? When it comes to cleaning up our energy usage, the devil is in the details, and the better we can see him, the better we can exorcise him.

The most effective feedback systems should also make the information relevant to the user. Not all of us know what a kWh (kilowatt hour) is, or what it means to be using 50 of them instead of 40 of them. But if this feedback were in the form of dollars out of our pockets, or CO2 being released into the atmosphere, or money into the hands of foreign nations, we would probably be a little more personally motivated to do something to reduce it.

Enter the smart meter. All over the nation, utilities are replacing regular energy meters with "smart meters", which allow better communication between the home and utility, and provide information every hour (or even every 15 minutes, for some). If you have one, it's likely your utility's website will allow you to go online and see your energy use broken down by day or even more finely, rather than by month.

This is an embarrassing admission for someone who studies energy efficiency, but I just found out that the townhouse I've been renting for two years has a smart meter. It was upgraded at some point and I never knew, and it's opened a world of information. See, here in Arizona, energy bills notoriously double or triple during the summer because A/C use shoots up. But I just went online and saw that on days where the temperature goes up, my energy use goes down, which makes absolutely no sense...of course, it would be great to have more granular information and see if the energy use has anything to do with A/C, but I can't tell that based on the information given. On the other hand, I've learned that my roommates and I need to be much more careful to consider time of use, because on some days almost half of our energy use has been during on-peak hours. Yipes.

To find higher-resolution information about your own home's energy use, check and see if your home has a smart meter (you can either call the utility or check your monthly statement). If you don't have one, you can ask if and when they plan on installing them in your neighborhood, because chances are they may be soon. And if still not, you can look into purchasing a TED or a Kill-A-Watt to show even finer granularity.

I forget who, but someone suggested that an energy bill should look like a phone bill - device, times, amounts, cost. I couldn't agree more. If it did, no matter our personal motivation, we would all be much more able to make informed decisions to curb our energy use.

Kickoff Time

Green is a beautiful color, and a very popular one these days. Entrepreneurs, celebrities, scientists, politicians, and regular everyday normal guys and gals like you and me are motivated to find eco-friendly ways to live well and save money. But it can be hard to keep up with the latest news, and as with all emerging trends, there is some confusion as to what is and isn't effective. We want to help the environment, and we want to save money doing it. But what's the best way? And, what can social psychology teach us about motivating others to be green?

For those of you who find yourselves thinking similar thoughts, welcome to Green Eggs and Sam! I’m Sam. I’m about to start the fifth year of my six-year Social Psychology PhD program at Arizona State University, and my dissertation will be on how to more effectively engage people in pro-environmentalism. It’s a field I’m just starting to explore, so I really welcome information and feedback! If you have ideas, share them! Suggestions – bring ‘em on! Let’s get a discussion going about how we can save money by going green, and how we can encourage others to do the same.

It's amazing what even little things can do - my roommate and I joined a CSA (community-supported agriculture) and we now help local farmers while saving about $40/month on vegetables. That is already a ginormous sum of money to graduate students, and there are so many more small changes we can all make to see serious savings.


There’s an apparently endless flow of green ideas these days. They range from the double-plus cool (Venice’s seaport plans to be powered completely by algae in 2011!) to the well-intentioned (100% compostable SunChips bags that sound like elephants waltzing on bubble-wrap every time you reach for a chip) to the “Whatever you’re on, I want some” (shower curtains with inflatable spikes that become fully stabby in about 4 minutes, prompting you to hurry). Some of these concepts can be easily integrated into our everyday lives, while others are guaranteed to be far more trouble than they’re worth (the Grass Wheel, a human-sized hamster wheel carpeted with grass so you can walk barefoot about town – forget about seeing oncoming traffic, by the way – springs to mind). Truly, all kinds of ideas.

But the exciting take-home message is that there are a lot of them. Green is the new black. We're only at the beginning of this wave, and it's smart to start riding it now, and let the savings - green and green - begin.

My second objective here is to review research on the social psychological principles that drive - or hinder - green behavior. As conservation becomes more popular (and lucrative), more researchers are wondering what makes people green. Why are some people more interested in going green than others? Why are some green behaviors more widely adopted than others? And why are some motivators more effective than others?

One finding in the persuasion literature that’s been replicated a thousand times is that people want to do what other people are doing. It’s called “social proof,” and the theory behind it is that when we’re in situations – particularly ambiguous ones – and need to decide which action is most appropriate, we look to other people for cues. Obviously, this can be applied to all kinds of social behavior and health interventions. Bob Cialdini, a social psychologist at ASU (recently retired), has done a number of studies on the effects of social proof on green behaviors.

In one recent study, Cialdini and two of his former graduate students, Noah Goldstein and Vlad Griskevicius, wanted to determine which type of messaging would be most useful in persuading hotel guests to reuse their bathroom towels. They found that pro-environment messaging that included descriptive norms (true information about what other guests were doing) was significantly more effective than pro-environment messaging alone. Cialdini has shown similar effects in the contexts of electricity usage, littering, and stealing petrified wood from national parks - informing people that others are acting environmentally conscious makes them want to do the same, and informing them that others are not, makes them not.

“JOIN YOUR FELLOW GUESTS IN HELPING TO SAVE THE ENVIRONMENT. Almost 75% of guests who are asked to participate in our new resource savings program do help by using their towels more than once. You can join your fellow guests in this program to help save the environment by reusing your towels during your stay.”

“HELP SAVE THE ENVIRONMENT. You can show your respect for nature and help save the environment by reusing your towels during your stay.”

Despite the fact that this research goes way back, it appears the word has not spread. My friend Joe pointed out something amusingly ironic the other day. Bob Cialdini’s office is down the hall from my lab, and just a few doors away from us is the bathroom, where the ASU Health and Counseling Student Action Committee has posted stickers encouraging people to wash their hands. Their stickers read: “1/3 of Americans don’t wash their hands after using the restroom – GROSS – and only 1/3 do it right.” There it is – 50 feet away from the man who revolutionized the fields of persuasion and social interventions, ASU’s HCSAC is unwittingly motivating people to not wash their hands after using the bathroom. I don’t blame them for this. The findings are not necessarily intuitive, and social scientists need to bridge the gap between their academic research and the public. With Green Eggs and Sam, I aspire to do that.

Green is indeed a beautiful color. We’d all love to see more of it, both outside and in our wallets. Let’s get clever about making that happen.

Thanks for reading - hope to see you back here soon!

-Sam
