The Case for Deliberation: #SmartGrid starts with Smart Government, #democracy

A more reliable power system that facilitates 21st century services and reduces economical inefficiency and emissions that are harmful to health and the environment hardly seems like a divisive idea.  However, lack of consumer education, consumer distrust of certain policies or technologies and an uncertain, constantly-shifting energy policy in a highly-polarized socio-political environment are some of the dogged issues that challenge a more swift and comprehensive modernization of our aging, mostly-unchanged 18th century power model in this age of the iPhone.

Every day, energy consumers from individuals, colleges, hospitals, government and commercial-industrial facilities are wasting obscene amounts of money, when there is, in my view, a clear business and ethical case for modernization and investors ready to cash in on a secure return in face of nervous stock markets.  Why aren't more power users seizing the opportunities (see, for example, lighting)? 


Utilities implement new technology like advanced metering infrastructure as part of an overall infrastructure upgrade to improve the quality and availability of existing service and opening the doors to new options for consumers, but misinformation, confusion, and distrust prevail in a number of communities.  How can we address this situation?

We look forward to your opinion and insights. 

This set of issues can be seen, however, in a greater context.  How are communities and organizations supposed to make smarter decisions if they are mis-informed? How can a relative consensus be reached if there is little, effective conversation, in this increasingly distracted and polarized society?  Who has the time to become an expert in energy, healthcare, fiscal, foreign, environmental, and myriads of other policies?  It's difficult to understand the big issues between the daily responsibilities, email jail, sitting in traffic, constant electronic stimuli, and the few things people try to squeeze in to remain human (enjoy time with family, friends, nature, community, and creative endeavors, and oh yes, sleep).  Most people, as demonstrated by low participation level is elections, see their singular vote as relatively insignificant in the big picture.  How do we overcome this so-called "rational ignorance"?

Unfortunately, the majority of our paid, elected officials don't seem very successful in the advancement of civilization, either.  How can we have smarter cities and countries without smarter policies?  The solution is apparent: we need more educated citizens.  Education is the first thing to get cut by politicians, so no luck there.  How about the Internet and its repository of knowledge and news media from multiple perspectives, including analysis by more independent journalists.  Unfortunately, misperceptions are resilient as humans aren't typically motivated to change their views, so we have a tendency to find media and information that re-enforces our current biases and paradigms.  This problem is looking more intractable by the minute.

Deliberative Polling

The problem is not that "the masses," the "common people" are stupid, inept, or unwise.  In fact, recent experiments with a more direct form of democracy prove quite the contrary.  We do not have a shortage of intelligence.  What we lack is effective dialogue. 

It is also not enough to ask people for their "opinion."  Mere opinion polls or the common notion of internet direct democracy do not reflect the wisest answers a people can provide, because they do not reflect what people think.  People hardly think when answering polls.  Ask most people about "microgrids" and you will likely draw stares.  However, if you simply poll them about it with a yes, no, or don't know question, you will magically have strong opinions (apparently).  The most scientific and inclusive poll is rendered useless unless respondants are minimally qualified to answer.  Who gets to decide who is sufficiently lucid in a matter?

"Asked for their opinion of the [fictious "Public Affairs Act of 1975"], large percentages of the public either supported or opposed it, even though no such act was ever passed. In 1995, The Washington Post celebrated the "twentieth unanniversary" of the nonexistent act by asking respondents about its "repeal." Half the respondents were told that President Clinton wanted to repeal the act; the other half were informed that the "Republican Congress" favored its repeal. The respondents apparently used these cues to guide their answers, without recognizing the fictional character of the entire endeavor."
Fishkin/Akerman

Enter the Deliberative Polling(R) method.  A statistically-significant and demographically and attitudinally representative sample of a population is invited to deliberate on a policy issue: how to address an aging, costly electric infrastructure?  Experts representing different opinions and relevant areas of expertise are also invited.  Deliberative Polling, developed by Dr. Fishkin from Stanford University's Center for Deliberative Democracy, engages a microcosm of society in discussion and gives them a chance to listen to and question experts.  The results have been applied toward conflict resolution, energy policy, governance, health policy and other areas from municipalities to states and even at an event at the European Parliament with representatives of 27 nations who spoke 23 different languages.

The case of Texas is particularly interesting.  A conventional fuel industry stronghold, which was 49th in the U.S. in wind energy production, became a leader in renewable energy generation, with the support of electric energy consumers.  It is an example of how decision-making and policies are more intelligent and resilient for the long-term when we help enough people to take the time from their busy lives to really learn and debate issues.

With deliberative polls, on the other hand, people actually have the chance to think and, golly, even change their mind.  It also brings people closer together because they get to see other people's points of view and it is harder to demonize people you actually get to know a little.  Northern Ireland Catholics and Protestants agreeing that their children should spend more time together.  Chinese villagers contributing to the discussion of budget priorities.  Americans agreeing on specific, smarter energy policies.  Would there have been less resistance to smart meters based on misinformation regarding RF, security, and other issues and a better understanding of why they are needed to begin with, if there had been deliberative polling activities so customers have a chance to educate themselves and reach their own conclusions and consensus?

Smart City Network interview - #SmartGrid Update with Nelson Abreu

Smart grid communications networks:
are we looking at them in the right way?

Joined up thinking by reverse engineering the big picture could create a truly holistic smart network that works for everyone.

When it comes to designing smart grid communications networks the options are boundless. Utilities could opt for a fairly basic network that only does meter reading or diagnostics.They could invest in more sophisticated systems which also integrate applications like commercial area networking capabilities, speech automation, SCADA functions, distribution automation, substation automation, equipment delivery tracking, and more besides.

Others could also integrate public services offerings, such as internet and Wi-Fi capability.
Indeed, as CE Power Solutions’ Nelson Abreu points out: “there is really no one-size-fits-all solution”.
However, companies and municipalities should, he says, adopt a “holistic approach that tries to maximise network investments to bring the most value to communities” while taking into consideration security, liability, and general business strategy concerns.

Benefits abound

From a purely business perspective, there are operating efficiencies, cost savings and revenue recovery to be gained. There are social and environmental benefits to be had too, if the right approach is adopted.
“You’re bringing new value or enhancing the customer experience. And if it’s a municipal utility you’re improving the life, the liveability of your citizens by providing not just more utility services – electric related services – but also new communications services,” says the engineer who heads up CE Power Solutions Advanced Metering Infrastructure and Smart Grid services team.

Effective smart grids should, Abreu continues, enable utilities to provide more and more power with today’s ageing infrastructure “in a way that manages cost, improves the reliability of that system, and accommodates a greater renewable portfolio.”

In addition, they should also provide for “digital inclusion and digital government for societies that have segments of the population that are currently cut off from all of this…to bring information about their costs close to their hands so they are empowered to make better energy decisions, so they can save power and they can participate.”

And with better energy management, increased energy efficiency, and greater integration of renewable energy in grid networks, energy losses through distribution networks and emissions can also be cut significantly.
Abreu points out that just being able to give a customer hourly data/information about their energy consumption and enabling them to estimate their bills based on their current pattern of consumption produces a conservation effect of at least 4%. “That’s just by giving information,” he says. “If we really take all of this seriously we can achieve a significant saving while being able at the same time to feed more and more demand, but it will take a smarter approach no question.”

Designing your network

While many will adopt a phased-step approach to network design – taking an initial idea or business imperative and implementing solutions and expand the network system later when new goals are set or new technologies enter the market, Abreu suggests that this is inefficient and can be costly.

Instead, the key to successful smart grid investment is to adopt a reverse engineering mentality. You have to “begin with the end in mind” and “decide what the features you’re looking for are,” he says. Then work backwards from there.

“Is it only utility applications or do you want to provide a whole load of other services, like voice over IT or Wi-Fi, so you have this infrastructure that other companies can use to provide services? Depending on what you’re trying accomplish you are looking at different challenges.”

By working backwards from your desired outcome, you can identify potential opportunities you may not have considered or problems that you can provide solutions to before going live. The alterative being suddenly encountering major problems once the system is operating and being dumped with the additional costs.

And you can build in flexibility and security by design from the start for later solutions to meet future needs while also planning for the unexpected.Abreu insists: “It is possible to have a good return on investment without taking shortcuts.” At present, he says, there is “a lot of disconnect between a planned benefit and then the actual feasibility of it with the current system.”  One example is outage management systems, which have “great benefits” like being able to determine outage sources quicker and, with controls, restore power to more people sooner.“Sounds brilliant, but sometimes that is not really tested out in the field under normal field conditions,” he says.Moreover, even if a network does work well in normal conditions, “does it work well under the worst conditions? That’s a completely different question.”

Processing

Another big piece of the puzzle, other than the technology, is the processing.
“You are used to running [your operations] a certain way and now you have a deluge of data and new features,” Abreu says, so companies have to plan for handling the increased volume of data, know how to use it and manage its flow between different departments.“The equipment has to move a certain way, the data has to flow a certain way, and then you want to use that actionable data for some useful purpose,” he stresses.It “could tell you something about impending failure, how well the communications network is performing in a certain area, whether somebody is stealing power.”

While no system will ever be flawless, his advice is always to plan for the unexpected when designing a network, particularly if planning to do so in a phased approach. “Perhaps you have a perfectly well functioning meter and network communications card and access points, but when your try to integrate all of this sometimes they do not inter-operate the way you would expect or in the field there’s some condition that you hadn’t foreseen.”Fluctuating and extreme temperatures, humidity, surges, harmonics, outages and more should all be factored in with a view to how the system, as a whole, may react.

Why new-generation LED lighting is set to make cities greener with Dr. Torben Riise of Green Air International

Reducing the consumption of energy makes sense for any business and household, but more than that, it is critical from an ecological point of view. Dr. Torben Riise, COO of US-based Green Air International (GAI), is one of the most knowledgable and enthusiastic proponents of the latest LED technology. "If just 10% of the fluorescent tubes in the U.S. were converted to LED tubes, which typically save from 40 to 60% of lighting energy costs, we could prevent greenhouse gasses equivalent to 4 million cars and decommission over 50 coal burning power plants, and eliminate mercury from the environment – every year! And we would save $6 Bn in electricity costs in the process."

According to Dr. Riise, "only 10-30% of the energy used by non-LED bulbs or tubes like incandescent and fluorescent go to producing light, the rest is wasted as heat."  Yesterday's LEDs suffered from the same issue, which also led to shorter lifetimes: heat not only raises A/C bills, it also accelerates the decay of lighting equipment itself.

In the last 18 months, we have seen the emergence of new-generation, ultra-efficient LED lighting with negligible heat radiation and burn times in the order of 50,000 hours burn time (over 5 years of continuous use or more than 10 years if used half of the day or less).  LED's are not deteriorated by repeated switching on and off through energy-saving sensors and timing technologies, as are fluorescents for example. 

There have also been significant improvements in the quality and intensity of the lighting: there are various "kelvin" ratings available (different warmths to suit different applications or environments from hospitals to offices or restaurants).  Successful projects have included parking lots, administrative buildings, college campuses, hospitals, airports, manufacturing facilities, government facilities, and municipal lighting. 

Utmost on the minds of most parties is the business case or return on investment. With an ROI typically ranging from 1 to 2 years, and warrantees of 5 or more years, and expected life cycle that far surpasses this (10 to 15 years), "many consider it practically unethical not to do it."  Investors, on the other hand, see an opportunity to help those entities that lack the capital for the investment and see it as a secure return in a time of weak and volatile market conditions, so Green Air International has found that financing in the form of lease-to-own and other instruments has not been difficult to secure for customers that require it.  With the rise of micro-equity financing, small businesses should find it even easier to raise the capital required for energy upgrades like this one with a comprehensive analysis by an expert. 

"There are different players in the market, but we have focused on finding the right LED light products – meaning the optimal solution between high quality and affordable prices – and establishing a partnership with the manufacturer.  Some times a product seems cheaper, but when you do a life cycle analysis it falls short compared to other alternatives."

The so-called "negawatt" (negative watt) industry is beginning to pick up and LED's are poised to play an important role.  It is both an opportunity for communities and other entities to save green, go green, and for enterpreneurs like Dr. Riise to capitalize on a percentage of money that is already being spent in the form of wasted energy.  By reducing electric bills with quality products, we can all win.

Disruptive Energy Development Imminent? Low-Energy Nuclear Reaction in the News



When hydrogen, the main element of water, is introduced to a small piece of the metal nickel or palladium, a reaction releases more energy (in the form of heat and light) than was introduced.  The law of conservation of energy would imply the "excess heat" involved is released from the nucleus, however this nuclear energy is purportedly non-radioactive.  Hydrogen is the most abundant element in the universe and the economic efficiency could be 10 to 30 times that of conventional fuels (Energy Return on Energy Invested) by some predictions.

Recently, the media is reporting that often-derided cold fusion (also known as low-energy nuclear reaction - LENR) is being taken more seriously than ever and a breakthrough, though largely considered unlikely, could take the energy industry and the entire world by surprise.  It would easily rank among the most disruptive technologies in history. 

US News reports "LENR demonstration projects recently initiated at respected places like MIT, the University of Missouri, and the University of Bologna; public presentations by executives at one of the world's largest instrument companies, National Instruments, apparently designed to attract the top LENR researchers into a project to test and quantify observed LENR effects; and a July report from the European Commission's research and development center that LENR at least has sustainable future energy technology potential. But near the top of the cold fusion research community's hit parade are musings from NASA, like the fact that the agency apparently filed two LENR-related patents last year and that a leading NASA scientist has indicated that LENR is real enough to pay attention to and study."

CBS News' 60 Minutes reported on renewed interest in the technology, featuring a some-what vindicated Fleischmann. The Financial Times also comments that "a new report by Boeing for Nasa, includes LENR among the options for powering a future generation of "ultra green aircraft'" in a piece recalling the recently-deceased Martin Fleischmann who, with Stanley Pons, first caused a stir about cold fusion in 1989.

So while few highly-reputable entities are quite ready to announce that LENR is on the renewables map, many see some hope for plentiful, clean energy for our world as important agencies and companies have rekindled interest.  We maintain an open mind, but chances are our efforts to modernize the utility industry will remain inexorable.

Green Waves in Copenhagen and other increasingly Smart Cities

Had lunch with a good friend and colleague in the smart energy industry, Dr. Torben Riise of Green Air International, who had just returned from his native Denmark.  We discussed how in Europe, so-called "green waves" are more prevalent and have been around for a couple of decades.  Green waves encourage cyclists and motorists to maintain a certain speed range by continually meeting green lights when they keep to the range and red lights when they do not.  This continual flow of vehicles cuts down wait time (time lost has it's economic impact) as well as reduced emissions from less acceleration and breaking action.  Perhaps, this is one more reason why the Danes are surveyed as one of the happiest people on Earth.
