The Internet of things and computational energy efficiency

April 9, 2012

Lynne Kiesling

Today in Technology Review, Jonathan Koomey has an interesting analysis of computational energy efficiency. We’re all familiar with Moore’s Law — Gordon Moore’s prediction that the number of transistors on a chip will double approximately every two years — but I did not realize that Moore’s Law is also borne out in improvements in the electrical efficiency of computation. Not only do we have more and more computational capacity per unit of area, each of those increased computations is performed with less electricity per computation. Koomey’s graphic showing this result over time is striking:

If this trend continues, Koomey claims, “ the power needed to perform a task requiring a fixed number of computations will continue to fall by half every 1.5 years (or a factor of 100 every decade). As a result, even smaller and less power-intensive computing devices will proliferate, paving the way for new mobile computing and communications applications that vastly increase our ability to collect and use data in real time.”

The ability to do more work with less effort is one of the most meaningful consequences of technological change, whether we’re talking about horse harnesses, water wheels, diesel engines, or digital sensors. One of the fascinating aspects of this improvement in computational electrical efficiency is that it opens up the feasibility of lots of distributed low-power sensors that get enough electricity to operate by harvesting “background energy flows”; Koomey’s example is small weather sensors that harvest stray energy from television and radio signals to send weather condition updates every five seconds. Imagine how a distributed network of such sensors could improve severe weather preparation, for example.

In the rest of this very interesting article, Koomey discusses the research and design efforts going into achieving such energy efficiency in data transmission and taking a system-level perspective on the electricity use of an entire network of devices. He also claims, and I think he’s right, that without such energy efficiency the “Internet of things” cannot become a reality.

The “Internet of things” framing of the Internet envisions interconnected networks of devices able to communicate their states, generate more granular information, and/or trigger tasks autonomously, without human intervention. For example, right now the water filter in my refrigerator needs to be replaced, which means I go down to the basement to see if I have one (which I do), and if using it reduces my filter inventory to one, I get online and order three more. It would economize on the most scarce resource in this supply chain — my time — if the filters had RFIDs and the refrigerator had an algorithm that would implement the inventory query and ordering process for me. I still have to install the new filter, but if that installation triggered an automated query and order, I’d come home from work in a few days to find a box of three water filters, with little effort on my part. That’s an example of the potential of the Internet of things; I’m sure you can come up with more examples that you would find valuable in your own work or personal lives, and I know you can see where this IoT framework intersects with consumer-focused smart grid networks.

Of course, details matter, such as getting the interoperability rules and security right so that only refrigerators can query the filter inventory in the house (no infiltrators, including the government), and so that the refrigerator’s connection to order replacements is secure. The same applies to electricity devices in the home and the digital meter, which is why one of the important phases in the process of smart grid development is laws protecting consumer privacy and property rights in data. Innovation in both computational power and computational energy efficiency have created this potential to create more value while economizing on the scarce resources of human time and attention.

UPDATE: And check this out: carbon nanotubes that can dump heat separately from current into a separate device, which should contribute to continued gains in computational energy efficiency.

Adam Smith and mirror neurons paper published

April 4, 2012

Lynne Kiesling

I mentioned a while ago my working paper on the neuroscience research on mirror neurons and its relevance for Adam Smith’s theory of sympathy developed in The Theory of Moral Sentiments (1759). After revision and some extremely helpful referee guidance, the paper has been published in The Review of Austrian Economics:

Mirror neuron research and Adam Smith’s concept of sympathy: Three points of correspondence

In The Theory of Moral Sentiments, Adam Smith asserts that humans have an innate interest in the fortunes of other people and desire for sympathy with others. In Smith’s theory, sympathy is an imperfectly reflected combination of emotion and judgment when one observes someone (the agent) in a particular situation, and imagines being that person in that situation. That imagination produces a degree of interconnectedness among individuals. Recent neuroscience research on mirror neurons provides evidence consistent with Smith’s assertion, suggesting that humans have an innate capability to understand the mental states of others at a neural level. A mirror neuron fires both when an agent acts and when an agent observes that action being performed by another; the name derives from the “mirroring” of the action in the brain of the observer. This neural network and the capabilities arising from it have three points of correspondence with important aspects of the Smithian sympathetic process: an agent’s situation as a stimulus or connection between two similar but separate agents, an external perspective on the actions of others, and an innate imaginative capacity that enables an observer to imagine herself as the agent, in the agent’s situation. Both this sympathetic process and the mirror neuron system predispose individuals toward coordination of the expression of their emotions and of their actions. In Smith’s model this decentralized coordination leads to the emergence of social order, bolstered and reinforced by the emergence and evolution of informal and formal institutions grounded in the sympathetic process. Social order grounded in this sympathetic process relies on a sense of interconnectedness and on shared meanings of actions, and the mirror neuron system predisposes humans toward such interconnection.

Applying Coase to wildlife preservation

April 3, 2012

Lynne Kiesling

I loved seeing pictures a couple of weeks ago of an endangered Bengal tiger and her cubs from a hidden camera. Large predator wildlife that roam and are territorial often face reductions in their territory when humans move in; in the Bengal tiger territory in India, both traditional farming and the construction of new vacation resorts increases the margin on which human uses of the land and tiger uses of the land conflict.

Note the way I said that: conflicting uses of a scarce resource, which for most resources we resolve peacefully and productively using property rights. But how do you do that when one use is territorial roaming and hunting by large predators? And how do you reconcile that with settled farming and tourism? This issue is the same as ranchers in Montana and Idaho faced with the reintroduction of the gray wolf, in a classic case in which Defenders of Wildlife members made voluntary contributions to compensate ranchers in the case of livestock killings.

This is an application of Coase’s framework for compensation for harms when there are conflicting uses of a resource — it recognizes wildlife territory as a valuable use of the resource, and compensates the other users for harms so that they don’t pursue the alternative of killing the wildlife.

I discussed one of my favorite examples of this in a class last quarter, as summarized in this NPR story: Namibia has instituted community ownership of wildlife, with village councils establishing “communal conservancies” and retaining the revenues associated with wildlife tourism … including wildlife hunting. Thus at the community level they earn revenues and have a pool for compensation in the case of livestock or crop damage. Both humans and wildlife are thriving and wildlife in Namibia are less prone to poaching, because the villages have property rights in the wildlife. They all prosper by cultivating wildlife in the way that we cultivate chickens.

The Wired article on the Bengal tiger case hints at a livestock compensation system funded by voluntary donations:

Although the tigers managed to kill a domestic cow, the WWF allegedly compensated the animal’s owner to prevent a retaliatory killing. While not an ideal arrangement, the organization asserts that the strategy works.

“The fact that the tigress survived and it was photographed later is an example of the cattle compensation scheme working when implemented in earnest,” the release stated.

The comparison of these cases suggests that perhaps the WWF should build on their cattle compensation strategy and act as an intermediary to work with the resorts in the Bengal forests to develop the potential for tiger tourism revenue at the resorts. If the resorts can profit from the free movement of tigers in their forest corridors, they are less likely to intrude on those corridors. Then farms and resorts and tigers can coexist and thrive.

Fracking at the Becker-Posner blog

April 2, 2012

Lynne Kiesling

Fracking and energy self-sufficiency is the topic of the week at the Becker-Posner blog. Becker’s contribution provides a stream-of-consciousness overview that is consistent with the past fracking discussions here; it touches on fuel source competition, the quest for self-sufficiency, the environmental impact of fracking, and the likely effects of fuel export regulation. I’m disturbed by seeing the spectre of fuel export regulations rise again, and Becker correctly points out that at least in oil, as long as the world price is higher than the US domestic price, export regulations will have no impact. And with natural gas inventories so high that natural gas prices are falling toward zero, why harm US natural gas companies by restricting their ability to export to countries with higher prices when we have a surfeit?

Becker’s ultimate focus is how fracking contributes to energy self-sufficiency in the US: “Fracking has made the US self-sufficient in gas, and it is leading to reduced imports of oil. If this progress continues, before too long US consumption of oil as well as natural gas would not be drastically affected even by an entire breakdown of imports from the Middle East.” This conclusion depends on there being a reasonably high elasticity of substitution between oil and natural gas, but natural gas is not perfectly substitutable for oil in all instances. Take, for example, electricity generation. According to the EIA’s Electric Power Annual for 2010, there are 55,647MW of generation capacity using petroleum for fuel, and 40.2 percent of that capacity is switchable with natural gas (Table 1.8). Total nameplate generation capacity in 2010 was 1,138,638MW (Table 1.2), which means that only 4.89% of generation capacity uses petroleum fuel, and thus that 1.96% of total nameplate capacity is switchable to natural gas. Electricity is not where the oil-natural gas substitutability is. Coal-natural gas is a different story, but neither Becker nor Posner touch on that analysis, which is less relevant to their main question of energy self-sufficiency.

Nutrition experience, research, and orthodoxy, with some economics parallels

March 26, 2012

Lynne Kiesling

Last week was our spring break, and I finally took some time to read Gary Taubes’ 2008 book Good Calories, Bad Calories. Taubes is an investigative science journalist who has been writing for years about the science of nutrition and epidemiology, and the book focuses on a long, careful, detailed narrative about how such science has evolved since the mid-19th century. One of the themes that emerges is that some of the most prominent researchers, particularly those advancing the dual hypotheses that fat causes heart disease/overeating causes obesity, did not test their hypotheses for falsification using controlled trials in designing their research, and are also personally invested in doing research that “proves them right”. Thus, Taubes argues, an orthodoxy has formed around these hypotheses when he finds the scientific support for them lacking, and similarly finds support for an alternate hypothesis — refined carbohydrates cause heart disease and obesity. But the orthodoxy resists testing that alternate hypothesis.

I have personal interest in this topic based on my own experience. As a high metabolism athlete for all of my life, I grew up being able to eat almost anything in unrestricted quantities. But when I got my first faculty job out of grad school (at WIlliam & Mary, yay!) in 1992, the combination of teaching and research duties with moving to a swampy climate against which my body rebelled meant a reduction in my activity, bloating because of the humidity, and weight gain. Without really thinking about it (because I hadn’t had to before), I reduced my meat consumption and substituted into (refined and unrefined) carbs. The next two years were right out of Taubes’ book — reduction in calories to manage weight while increasing exercise, but not having enough energy to actually make it meaningful, culminating in what is now known as metabolic syndrome complete with insulin resistance, hormone imbalance, and symptoms of polycystic ovarian syndrome. I then spent two years revamping my diet to reduce refined carbs, include more animal and vegetable protein at every meal, and monitor my hormone and energy levels, and succeeded in reversing all negative symptoms. I returned to the energy levels that have enabled me to do longer and longer distance cycling and triathlon endurance events and the demanding training for them. Even though I don’t eat low-fat, my triglycerides are so low that my doctor marvels at it. Taubes’ argument is consistent with my experience.

Economist Russ Roberts has been experimenting with his diet and exercise for the past six months, following broadly the same principles that I do (including the refined carbs on the weekend), and he reported in on Friday: 20 pounds lost, more energy, feeling of satiation, low triglycerides. Again, consistent with my experience.

You may know Russ for his outstanding EconTalk podcast series, and in November 2011 he interviewed Gary Taubes. The conversation was interesting and informative, and the podcast page lists lots of resources for further reading. One theme that Russ developed in the discussion was that in both nutrition research and economics research, the issues come up of orthodoxy and structuring research questions in ways that generate falsifiable hypotheses when you are studying such a complex, dynamic system as either the human diet/cardio/endocrine system or the human economy. The human traits that incline us toward orthodoxy, whether it’s wanting to prove ourselves right or appeal to authority or some other trait, have led to models and hypotheses that are not supportable or not even meaningfully testable/falsifiable. So for me reading Taubes’ book was a good cautionary tale of the value of humility beyond the analysis of low-carb/low-fat nutrition.

Another insight that comes up in the book that I would add to Russ’ comparison with macroeconomics is heterogeneity. Taubes is careful to point out that individuals have different metabolic experiences and achieve homeostasis with different combinations of fat, carbs, etc., so while low-carb nutrition may allow some people to strike a healthy heart and weight balance, others may be able to eat more carbs and do the same. Heterogeneity means that there’s no one-size-fits-all hypothesis … and as any Austrian macroeconomist will tell you, that’s the argument they put forth about macroeconomic models and aggregation. Heterogeneity in the capital structure in reality means that models abstracting from such heterogeneity are more likely to mislead.

Learn Liberty video: should government regulate monopolies?

March 21, 2012

Lynne Kiesling

I am happy to say that Learn Liberty has published another video that we did together. This one is a short one in which I talk about government regulation of monopolies, essentially laying out Schumpeter’s argument that when entry costs are low, monopolies do not persist because monopoly profit serves as a lure to entice entrepreneurs and innovators to create new value propositions (“new combinations”, in Schumpeter’s words) that break down market barriers and definitions.

Those of you with an electricity/natural monopoly background will notice that I assiduously stay away from economies of scale and subadditivity of costs as a cause of monopoly formation. Couldn’t keep the video at 3+ minutes if we opened that Pandora’s box!

The Learn Liberty page for the video also has a description and some discussion of the issues.

Innovative retail competition: is it finally starting … and in Chicago?

March 21, 2012

Lynne Kiesling

This may be the beginning of what I’ve been arguing for over the past decade plus … today in Smart Grid News, Jesse Berst reports that Constellation Energy has teamed up with Best Buy to enable customers to come into the store, switch their retail provider, and buy home energy management devices (see also the brief note in the Chicago Tribune). Jesse observes that

It has been fascinating to watch power retailing develop in areas such as Texas and the United Kingdom. In the early days, we thought it would be all about price. As it turns out, price is important but it is just the table stakes. To become a market leader, you have to establish brand trust. You have to bundle the power with other products or benefits. And you have to make that bundle ultra-easy to find and purchase.

Absolutely correct. This is the kind of Schumpeterian retail innovation that is a value-creating hallmark of competitive rivalry.

At first blush it also has some similarities with mobile phone retailing — I presume that the retail provider to which a customer can switch is Constellation, and not Direct Energy or any of the other retail providers in the Illinois residential market. I’ll be interested in seeing if Best Buy is willing to make similar arrangements with those retailers. If their contract with Constellation precludes such arrangements, then we run into the murky area of whether or not exclusive dealing contracts are anti-competitive. But if, say, Target strikes a deal with Direct Energy, and Costco and Walmart get in on this innovation, then the retail landscape really starts to look like mobile communications retailing, and things get very interesting.

Note also that this type of market channel is a way for consumers to learn, which is a crucial process in the liberalization of retail sales in an industry that has been vertically integrated and regulated for over a century. Regulation defines product characteristics and boundaries and thus determines the type of product that the consumer is purchasing, so for over a century residential customers haven’t had to think about what they are buying and whether there are ways for them to get more value out of the transaction and relationship. They had no choice, so why give it any thought? Now starts the process of individuals learning how and why they may create more and different value from changing their retail relationship and changing the technology they use in the purchase and management of the electricity they consume.

As it happens, the Best Buy in this pilot is my neighborhood store, so I’ll check it out and report back what’s interesting and important. Free the electricity consumer!

Antony Davies’ sobering federal debt summary

March 20, 2012

Lynne Kiesling

While we’re at Learn Liberty, and in light of today’s Congressional Republican federal government budget proposal, here’s economist Antony Davies on the implications of our government’s indebtedness.

When we covered this in my intro macro class this winter, it was sobering for my 18-20-year old students to realize that they are the people who will bear the costs of this debt burden.

Economists and philosophers on value

March 20, 2012

Lynne Kiesling

Got two spare minutes and want to spend it enriching yourself? Then watch this great Learn Liberty video from Aeon Skoble. Aeon’s a philosopher who also reads a lot of economics, so he’s in a distinctive position to make this important point — both economists and philosophers use the word “value”, but we mean different things by it. For economists, value is subjective and arises from preferences, context, perceptions that individuals possess. For philosophers, value is objective values, like rights, that are part of our objective moral framework for living together as heterogeneous individual agents in civil society. Moreover, the two concepts are complementary; for individuals to be able to act on and satisfy their diverse individual preferences, they rely on living in a social system grounded in respect for individual rights. Aeon explains that distinction beautifully here.

How fear affects policy: Adam Thierer on technopanics

March 14, 2012

Lynne Kiesling

Fear is a strong motivating factor, having evolved over millennia as we have protected ourselves against predators. Fear supports self-preservation by making us risk-averse and cautious. But such a deep, visceral, evolved emotion does not always serve our long-term objectives of thriving; it leads to maximin outcomes, and it is often mismatched to the actual threats to our self-preservation. As our environments change around us, we can fear things we shouldn’t and may not fear things that we should; we overthink everything and tend toward a “precautionary principle” approach, making us risk-averse and cautious.

I think such fear is a component in the persistence of regulation when it’s maladaptive to technological change, so I was happy to read Adam Thierer’s new Mercatus working paper, Technopanics, Threat Inflation, and the Danger of an Information Technology Precautionary Principle. Adam lays out a framework for analyzing fear-based attitudes toward technology and technological change that’s informed by economics, sociology, psychology, and rhetoric. He tackles the question of why, and how, participants in public policy debates use appeals to fear to sway opinion toward anticipatory regulation and forms of censorship:

While cyberspace has its fair share of troubles and troublemakers, there is no evidence that the Internet is leading to greater problems for society than previous technologies did. That has not stopped some from suggesting there are reasons to be particularly fearful of the Internet and new digital technologies. There are various individual and institutional factors at work that perpetuate fear-based reasoning and tactics.

He analyzes the use of “appeal to fear” and “appeal to force” logic in the construction of arguments in favor of regulation and censorship, focusing on case studies of online child safety and violent media and online privacy and cybersecurity. In deconstructing these arguments he identifies four ways that fear can be a myth: it may be empirically unfounded and lacking evidence, other variables may be more important in affecting behavior than the feared variable, not all individuals have the same reaction to the feared variable, and other approaches than regulation exist that can mitigate the consequences of the feared variable (pp. 5-6).

Adam introduces the phenomenon of the “technopanic”, which is “… a moral panic centered on societal fears about a particular contemporary technology” (p. 7). Because culture often evolves more slowly than technology, as we are adapting culturally to the new technology we can see these panic phenomena, which can result in demonizing the technology and can lead to calls to “do something”, typically some form of control-based anticipatory regulation or censorship. A crucial part of manipulating individual attitudes to tap into fear and create advocacy for and acceptance of such regulation is what Adam calls “threat inflation”:

Thus, fear appeals are facilitated by the use of threat inflation. Specifically, threat inflation involves the use of fear-inducing rhetoric to inflate artificially the potential harm a new development or technology poses to certain classes of the population, especially children, or to society or the economy at large. These rhetorical flourishes are empirically false or at least greatly blown out of proportion relative to the risk in question. (p. 9)

Allowing threat inflation and technopanics to drive policy outcomes is socially corrosive and wasteful; it diverts resources from their higher-valued uses in dealing with actual risks rather than inflated ones, and it creates an environment of suspicion and social control, particularly censorship and information control. After analyzing six factors that create conditions favorable for the development of threat inflation and technopanics regarding Internet technology (nostalgia, special interests, etc., well worth reading in detail), he proposes two categories of policy response that we should pursue instead of prohibition and anticipatory regulation: resiliency and adaptation. We build resiliency to threats through education, transparency, labeling, etc., and we adapt to living with risk through experimentation, trial-and-error, experience, and social norms. These two are complementary; information-sharing about best practices can shape social norms and get people to change their behavior without regulation. For example, I don’t sign my credit cards, but instead write “CHECK ID” in the signature line and present a photo ID when using them. Having store clerks and other shoppers witness my behavior to protect my identity may lead to their replication of it, and has led over time to a change in behavior (remember back in the 1990s when they used to write your phone number on the receipt? Yikes! But that behavior’s gone extinct.).

We cannot eliminate risk through resilience and adaptation, but we can’t eliminate it through regulation either. Better to have strong, flexible, adaptable institutions and practices that enable us to continue thriving in unknown and changing conditions, while we enjoy the substantial benefits of technological creativity. While I heartily recommend Adam’s paper to you all as a good and thought-provoking read, he also summarizes it in this recent Forbes column.

I would extend Adam’s argument to apply to two case studies. The first is smart grid technology. Fear-based arguments abound in electricity, usually grounded (pun intended!) in the physical reality that electricity is dangerous. But after a century of economic regulation to serve particular social policy objectives, fear-based arguments also show up in arguments against moving away from the status quo both technologically and more economically in general; in my experience these fear-based arguments are used most to advocate for the status quo on behalf of low-income consumers and the elderly, and for that reason I find the use of fear-based arguments heart-wrenching, because when they succeed they deprive vulnerable populations of the benefits of innovation. Another current example is the arguments that digital meters, which transmit data using radio frequency wireless networks and thus emit low-level electromagnetic fields, are making people sick. Despite the absence of any scientific evidence consistent with this hypothesis, California and Maine are using these fear-based claims as a basis for allowing customers to opt out of having a digital meter installed (I have other analyses of this phenomenon, but that’s for another time …).

The second case is threat inflation and the exaggeration of fear to extend the security state. Each of Adam’s six factors contributing to threat inflation is applicable to the growth of the security state — nostalgia, pessimistic bias, “bad news sells”, the political power of the military-security-industrial complex, and so on. The persistence of threat inflation enables these special interests to use fear-based arguments to perpetuate the false belief that we are under constant, persistent threat beyond the actual threat level; this false belief creates the incentives in politicians to “do something” so that they don’t appear “soft on terror” and therefore risk not getting reelected; that political incentive enables security and defense companies to lobby politicians to buy their cutting-edge technologies at very great taxpayer expense to demonstrate to voters that they are “doing something” (even though the technologies have high false positive rates, can be fooled easily, and are more for symbolic security theater than for addressing the most relevant risks that we actually do face).

In both cases, a resiliency-oriented public policy approach would be a substantial improvement on the control-oriented regulation that is not focused on the most meaningful or relevant threats, be they health threats, economic threats, or security threats, from technological dynamism.
