My Op-Ed in today's New York Times,  "Making Every Oil Calorie Count", proposes a solution to energy obesity in America. It imagines a high-tech labeling system dubbed "Decal" (for daily energy calories) that would track the consumption of energy in all aspects of our lives, and make it easy to use less.

Here's an excerpt:

Americans use more oil than people in any other developed country, about twice as much per capita, on average, as Britons. Indeed, our appetite for petroleum, like our fondness of fast foods, has spawned a kind of obesity epidemic, but one without conspicuous symptoms like high blood pressure and diabetes. And because we don’t see how much energy goes into the products and services we purchase, we’re shielded from knowing the full extent of our personal energy demands — and unprepared when rising fuel prices increase the cost of everything else.

This illusion stems, in part, from a measurement problem: while we expect and understand labels on our food products that quantify caloric, fat and nutrient content, we have no clear way of measuring the amount of energy it takes to make our products and propel our daily activities.

There’s no reason we can’t have energy labels, too. For example, in Europe, Tesco, a supermarket chain, has begun a “carbon labeling” program for some 500 products, which displays the amount of energy consumed and greenhouse gases generated from their production, transportation and use.

We could do the same thing here, with labels providing a product or service’s “daily energy calories.” Along with physical labels, imagine a smartphone app — we’ll call it “Decal” for short — that would scan a product’s bar code and report how much energy it took to produce that item.
