Climate Smart and Energy Wise

Climate Smart & Energy Wise: Advancing Science Literacy, Knowledge, and Know-How by Mark McCaffrey is a book written primarily for teachers, to give them the information and tools they need to bring the topic of climate change effectively to their classrooms. It addresses the Climate Literacy and Energy Literacy frameworks, designed to guide teaching this important topic.

The book provides basics on climate and energy, approaches to teaching about climate and energy, and of special interest for teachers, syncing the topics with existing standards. The main point of the book is to get teachers up to speed, but this is not restricted to teachers at a certain level, or for that matter, a certain topic, in that climate change and energy can be incorporated in a very wide range of electives and mainstream classes. The goal of teaching climate literacy is developed by focusing on the “seven essential principles”:

  1. The sun is the primary source of energy for Earth’s climate system.
  2. Climate is regulated by complex interactions among components of the Earth system.
  3. Life on Earth depends on, is shaped by, and affects climate.
  4. Climate varies over space and time through both natural and human processes.
  5. Our understanding of the climate system is improved through observation, theoretical studies, and modeling.
  6. Human activities are impacting the climate system.
  7. Climate change will have consequences for the Earth system and human lives.

And, similarly, there are seven organizing concepts for teaching energy:

  1. Energy is a physical quantity that follows precise natural laws.
  2. Physical processes on Earth are the result of energy flow through the Earth system.
  3. Biological processes depend on energy flow through the Earth system.
  4. Various sources of energy can be used to power human activities, and often this energy must be transferred from source to destination.
  5. Energy decisions are influenced by economic, political, environmental, and social factors.
  6. The amount of energy used by human society depends on many factors.
  7. The quality of life of individuals and societies is affected by energy choices.

There is a chapter on countering denialism, and a chapter on mainstream activism.

Mark McCaffrey is the Programs and Policy Director for these topics at the National Center for Science Education, and this book is an NCSE project. McCaffrey has blogged about the contents of the book on the NCSE blog; his first entry is here. In his own words:

…if well presented and handled with creativity and care, climate and energy issues are ideal interdisciplinary and integrating themes, potentially linking the sciences with mathematics, language arts, geography, history, arts, social studies and civics, and at the college level, bringing in psychology, sociology, writing and rhetoric, philosophy, business…. You get the picture.

Most importantly, climate and energy are topics that are imperative to teach if we are going to effectively respond to these challenges, and make informed climate and energy decisions.

Climate Smart & Energy Wise: Advancing Science Literacy, Knowledge, and Know-How is well written, well laid out, a good read but also an excellent on-the-shelf reference book for educators designing or updating courses. It is coming out later this month and costs only $25.00. A great gift for your favorite teacher!

US CO2 Output Up, and how to lie with graphs

Above is a graphic someone tossed at me on twitter the other day. It makes it look like CO2 emissions went way up then went way down so everything is fine. It is, of course, a lie, of sorts.

IT is actually kind of hard to find a graph just for US CO2 that goes back in historic time, but this graphic for the global energy industry clearly shows that the big picture is an upward trend:

Emission_by_Region - RRohde

The dip we see in recent years is simply an effect of the economy going bad, and things people do that emit CO2 being done somewhat less. Kevin Schultz wrote this up on his blog:

After a five-year decrease in the amount of carbon dioxide pumped into the atmosphere from burning fossil fuels, U.S. greenhouse gas emissions are on the rise again. The culprit: a rebounding economy.

CO2 emissions from fossil fuels rose 2.39 percent in 2013 compared with 2012 and grew 7.45 percent for the first two months of 2014 compared with the same period in 2013, according to new data released by the U.S. Energy Information Administration (EIA). The jump puts an end to the annual decrease that had occurred from 2008 through 2012.

So be careful of that misleading graph, and keep working on reducing emission. This problem will not solve itself.

Energy and Climate Change Items of Interest

Every one of these is a topic I’d like to write an entire blog post about but I don’t have time right now. So, YOU write the blog post!

In Michigan there is an emerging debate and discussion about using the Vast Forests in that state to provide energy. This is a good idea because it does not involve the release of fossil Carbon from fossil fuels. It is a bad idea because it involves the release of Carbon currently trapped in a medium term and important Carbon sink. It is interesting because it highlights a key feature of the whole energy and climate change thing. Sun makes burnable stuff, we burn it. This is just another version of this where we would be relying on trees, and on whatever level of efficiency forests provide. I assume we can build a better mousetrap than this.

In Minnesota, Xcel Energy has broken a record:

MINNEAPOLIS — Xcel Energy issued a press release Wednesday declaring that it had achieved a milestone when 46 percent of customers’ electricity needs in the Upper Midwest were met by wind energy at 3 a.m. Sunday.

That’s an all-time high for Xcel, which recently was named the nation’s top wind power provider for the 10th straight year. At the time of the record, 1,622 of 3,512 megawatts were being produced by wind turbines.

It has been windy in Minnesota over the last few days! Anyway, details here.

When an oil spill or similar environmental disaster happens we are assured that new technologies will make such a thing much more unlikely in the future. Well, “New “Safer” Tank Cars Were Involved in Lynchburg, VA, Oil Train Fire.

And while we are speaking of accidents, “Accident Leads to Scrutiny of Oil Sand Production” and “Fracking disposal wells may cause quakes 30 miles away, researchers say“.

Climate change and President Obama’s legacy:

The satellite images viewed by President Obama before a meeting with eight Western governors were stark, showing how snowpack in California’s mountains had shrunk by 86 percent in a single year.

“It was a ‘Houston, we have a problem’ moment,” recalled White House counselor John D. Podesta, one of two aides who briefed the president that February day. Obama mentioned the images several times as he warned the governors that political leaders had no choice but to cope with global warming’s impact.

Read Juliet Eilperin’s interesting essay in the Washington Post.

Hydro power is “Carbon Free” but also can be environmentally destructive, and it only provides a small amount of our electricity. But, we could in theory get more. A “DOE study suggests America’s rivers are troves of vast untapped hydropower potential and developing many of them could help combat climate change by using renewable energy to reduce reliance on coal-fired power plants that emit climate-changing greenhouse gases.” Climate Central item is HERE.

And finally, Some see proposed wind farm as a threat in Squaw Creek National Wildlife Refuge. I’ve been planning to write up a 10,000 Birds post updating this topic, so maybe that will be my next post there. In the mean time I want to make a proposal. Invent a wind turbine that is very visible to birds. It will be less efficient than other turbines. So what? We need the clean energy, we can pay more for some of it. Just invent the damn thing. I have a design in mind, if you are a serious engineers in the wind power area contact me and I’ll tell you how it works. We’ll share the patent.

Koch Brothers And Utilities Try To Ruin Solar Energy

Solar energy is one of the best and most easily implemented options to reduce our use of fossil Carbon based fuels. Never mind that the sun is only up and strong for part of the day, and is often covered by clouds. If you put a few square meters of solar panels on the roof of a residential or commercial building, you get clean and free (after the investment into the system) electricity thereafter. Clearly, this is an underutilized technology. In recent years there has been a precipitous drop in the cost of implementing solar energy, so it is now economically kinda dumb to not put solar panels on your roof. Worked out over the long term, a properly done implementation of solar can save a home owner hundreds of dollars a year after accounting for the cost of the equipment, installation, maintenance, and permitting fees. And, since part of your energy is coming from non-Carbon based sources, by implementing solar you also save money on those Survivalist Training Courses you might otherwise have to buy for your grandchildren if you expect your progeny to continue to exist in the not-too-distant future.

But every dollar that you save by using solar energy is a sum of money not earned by utilities and the owners of the energy production system, which generally translates into Your Power Company + The Koch Brothers.

So, naturally, the Koch Brothers and various energy utilities have been investing money to make sure that solar is not worth it. One way to reduce the viability of solar to the home owner or small business is to reduce or eliminate the payments that utilities make back to the owner of the solar energy system in the purchase of excess energy produced during those bright sunny days when your solar panels are at home doing their job while you are off at work doing your job.

A Sunday Review editorial published over the weekend in the New York Times discusses this strategy. The Koch Brothers and others have, over the last few months, ramped up their spending to reduce or eliminate renewable energy incentives. Since for the most part utilities are regulated state by state, this is being done at the state level. At present, owing to grassroots organizing combined with a bit of rare common sense in state legislatures, most states require utilities to pay for energy fed back into the system by homeowners with small power plants. But, there are moves to reduce these paybacks or to charge homeowners a surcharge so the utilities actually make money on your electricity, to the extent that for many homeowners, installing solar may not be worth it. This is a kick in the groin for homeowners and small businesses who have already installed systems with certain expectation of cost and benefit, and it is a kick in the groin for the planet, and our future, because the shift to solar for some of our energy will be slowed down by these nefarious changes in regulation.

According to the NYT,

Oklahoma lawmakers recently approved such a surcharge at the behest of the American Legislative Exchange Council, the conservative group that often dictates bills to Republican statehouses and receives financing from the utility industry and fossil-fuel producers, including the Kochs. As The Los Angeles Times reported recently, the Kochs and ALEC have made similar efforts in other states, though they were beaten back by solar advocates in Kansas and the surtax was reduced to $5 a month in Arizona.

But the Big Carbon advocates aren’t giving up. The same group is trying to repeal or freeze Ohio’s requirement that 12.5 percent of the state’s electric power come from renewable sources like solar and wind by 2025. Twenty-nine states have established similar standards that call for 10 percent or more in renewable power. These states can now anticipate well-financed campaigns to eliminate these targets or scale them back.

In some contexts, the utilities and their lobbyists are making the simple, straight forward, and correct, argument that wanton installation and use of domestic solar will hurt their profits. But we all know that the number one problem with our energy system at present is that it is driven by profits of the few at the cost (often through externalities, such as everybody dies etc. etc.) all others. Energy utilities should be viable, not profitable, and everyone knows and agrees with that. (Except the energy utilities.) And, of course, the Wealthiest People In The World need to keep their Mega Yachts well appointed, so that’s a consideration that most common people take into account … and ignore, resent, and get mad about.

So, as the NYT points out, Koch and friends have an alternative strategy to gain the hearts, minds, and monies of the American people.

Solar expansion, they claim, will actually hurt consumers. The Arizona Public Service Company, the state’s largest utility, funneled large sums through a Koch operative to a nonprofit group that ran an ad claiming net metering would hurt older people on fixed incomes by raising electric rates. The ad tried to link the requirement to President Obama. Another Koch ad likens the renewable-energy requirement to health care reform, the ultimate insult in that world. “Like Obamacare, it’s another government mandate we can’t afford,” the narrator says.

Here’s the ad that blames Obama for wanting to harm old people:

Thanks, Obama!

Here’s the ad that links Solar Energy and Obama Care to Solar Energy:

Do you find this annoying? Of course you do. But there is something you can do about it.

Since this battle is being fought at the state level in the US, if you are a US citizen and voter, just contact your state reps and tell them that you do not appreciate what the Koch Brothers and various utilities are doing. Send them a link to the NYT editorial …

… and tell them that you support home owners and businesses that want to use solar and that you don’t want to see any hint of legislation to interfere with that effort. Not sure who your state representatives are (or is, in some states, you have only one)? CLICK HERE to find out.

You might decide to not do this for one of two reasons, and in both cases you are wrong so please consider. Incorrect reason 1) “I live in a state that has already implemented good laws and regulations and I see no evidence that the Koch Brothers and Kin are coming after us, so why bother?” The reason this is wrong is that they are coming after your stat, you just don’t know it yet. Your letter, phone call, or email to your reps are a form of inoculation, imperfect, but potentially effective, against this. Incorrect reason 2) “My particular legislators are cool. They won’t vote in favor of any such Koch Sponsored Legislation (KSL).” That is wrong because your legislators are embedded in a complex system of give and take. It’s called “Politics.” They need a record of having been contacted by numerous constituents about this. That only happens if you contact them. So just do it.

Shawn Otto, in his book “Fool Me Twice: Fighting the Assault on Science in America,” reports that he once asked a legislator (at the federal level) what constituted a “groundswell” of support for a particular issue. I don’t recall the exact number, but Shawn was told something to the effect and of the magnitude of “a dozen or so” letters from constituents. Note, I said letters, not emails. A letter looks like this:

mail02

It’s a tremendous amount of work. You have to print it out, find an envelope somewhere, get a “stamp” which costs several cents, and put the object in one of these:

images

… but it is worth it. Every one of those is probably worth hundreds of emails, because emails can be automated. But just to be sure, you can send the same text as an email and as a “letter” and while you are at it, send a tweet or two. When you send a tweet to your representatives, be sure that the tweet does not begin with the @ sign because if it does, it will not be generally viewable to others who follow your Twitter account. Put a “.” or something (not a space) first, then others will see what you are up to and perhaps join in. (See this for how to use Twitter more effectively.)

OK, that’s all for now. Imma go tweet my reps. See you later.

Energy Connections: Shocking climate change vs. shocking solar power

One of the most important realizations of climate change research is exemplified in this graphic from Weather Uderground:

Caption from original: "Rate of temperature change today (red) and in the PETM (blue). Temperature rose steadily in the PETM due to the slow release of greenhouse gas (around 2 billion tons per year). Today, fossil fuel burning is leading to 30 billion tons of carbon released into the atmosphere every year, driving temperature up at an incredible rate.:

Temperature rose steadily in the PETM due to the slow release of greenhouse gas (around 2 billion tons per year). Today, fossil fuel burning is leading to 30 billion tons of carbon released into the atmosphere every year, driving temperature up at an incredible rate.:

The point is this. The PETM (Paleocene-Eocene thermal maximum, millions of years ago) was a period of high levels of CO2 in the atmosphere which caused significant warming. It is an example of both relatively rapid and intense climate change caused by CO2 acting as a greenhouse gas. The red line is, of course, our current estimated rate of change given current rates of release of fossil carbon into the atmosphere. This gives scientists pause because the rate of change in a system is often a more significant factor than the state of a system after the change. A simple example is motion. Assume you are standing on a commuter train moving at 50 km/h. If the train suddenly sped up to 100 km/h it might knock you down and even cause injury. But if the train increased its speed by 1 or 2 km/h every minute or so, you would not even notice and eventually you would be cruising along happily at double the speed.

It isn’t just the high rate of change in climate that concerns us. It is also the fact that this rate of change has never been observed in nature; we have no record of such a rapid and large change happening in the paleo record. For many aspects of the Earth’s climate system, we simply don’t know what would happen under such rapid change because there is no point of reference, no precedent, for such a thing.

But there is another graph that also shows a very high rate of change, in a different system, that may allow us to feel a bit better. One way to avoid such an increase in release of fossil Carbon is to rapidly transition to non-Carbon sources of energy such as solar. One way for that to happen is if solar energy become economically more viable very quickly. Ideally, the rate of change in the economic viability of solar energy would be very fast, enough to knock you off your metaphorical feet. And, apparently, that is the case. From a study described here:

From the source: "Solar is now – in the right conditions – cheaper than oil and Asian LNG on an MMBTU basis. Yes, we are using utility- scale solar costs in developing markets with lots of sun. But that describes the growth markets for global energy today. For these markets solar is just cheap, clean, convenient, reliable energy. And since it is a technology, it will get even cheaper over time. Fossil fuel extraction costs will keep rising. "

There are caveats, as noted. But solar power is, seemingly going to have its day in the sun sooner than later.

Peak Oil vs. Peak Chocolate Chip Cookies

Peak Oil is a controversial concept. Some people actually think that the production of oil in nature is continuous (which is a tiny bit, but hardly at all, true) so we can keep pumping oil out of the ground and it will just keep being produced by tiny microbes. But aside from that particular, and annoying, made-up controversy, “real” Peak Oil (or should I say Peak Real Oil) is still controversial. Peak Oil is defined as the moment when the maximum rate of petroleum extraction occurs, and thereafter production declines steadily, like on a bell curve. But that is, in my view, the wrong way to look at it. I would like to propose a different way, and to understand this approach we first must understand chocolate chip cookies. Which is not difficult.

If you make a batch of chocolate chip cookies, then everyone in the house starts to eat them, when does “Peak Chocolate Chip Cookies” occur? Obviously, this occurs the moment the chocolate chip cookies are pulled out of the oven. That is when the maximum number of cookies are available. Subsequent “extraction” rates are not a function of cookie availability, but rather, the social politics of the household, the number of hungry people, and other factors. The cookies will be “extracted” at any one of a number of rate functions. Often, the initial number of cookies extracted from the cooling rack, cookie plate, or cookie jar starts out very slow because they are too hot and have not achieved structural stability so they are hard to eat, especially for dunkers. But then the rate may go way up and then, because the cookies are being consumed rapidly, and/or people become sated, it may go down. Or, the baker of the cookies may bake them in secret and hide them in the cookie jar until after dinner, then reveal the existence of the cookies at which time peak extraction commences. Or there may be house rules as to how many cookies everyone can eat which will affect the rate of extraction. And so on. But no matter what, Peak Cookie happened the moment the cookies were pulled, baked, from the oven. (We will leave the consumption of cookie dough prior to baking for discussion at another time.) The point is, it is easy to see that “Peak Cookie” happens at the moment baking ends, and the variation in extraction rate thereafter is a function of many factors that will vary from household to household and from time to time. And all those factors are important events or processes. Peak Cookie, as a concept, is uninformative of the social dynamics, demographics, and collective individual proclivities of the household, which really are the things that matter.

This analogy reveals the fact that the “peak” (measured as production) is only part of a function of how much substance (cookies, oil) there is, and is, until the amount of substance is just about to run out, more a function of other things. For oil, this includes knowledge (of oil deposits), technology (to extract harder to get at oil), geopolitics (some oil is in countries that are currently in a snit, or that we don’t talk to), and of course, economics.

And, really, what I want to know about, and what you want to know about, is our own personal peak oil, or more manageably, our encompassing society’s peak oil. For instance, if a large deposit of oil is unavailable because we say so (for conservation reasons unrelated to petroleum) or political reasons (because it is buried beneath an enemy’s territory) then we can’t count that oil in our calculations of availability, and thus, extraction. Oil that is in our own country and not under a national park, on the other hand, is different.

In this way, perhaps a better way to think about Peak Oil is to look at the historical complexity of the process of bringing this fossil (oil is a fossil) to a place and refine it to a form that we can burn in our homes, cars or factories. Looked at it this way, from the perspective of the United States, we have had several “Peak Oil” moments.

Not counting whale oil, we experienced our first Peak Oil moment when the vast oil fields in Texas and Oklahoma and a few other places started to dry up. When that happened we started to buy more oil from countries that we really had very little respect or love for. Today, we get a fair amount of oil from a region of the world where we occasionally have to go to war to keep that oil supply open. And, we have to look the other way when the governments of those countries continue with highly objectionable policies. Imagine having a two grocery stores near your house. One of them is run by a really nice family, pillars of the community, your kids go to school with their kids, everything is fine. The other is run by a paroled sex offender who is also suspected of being a mass murderer. Plus he is a jerk. At first you always get your groceries at the store run by the nice family. But then they retire and move to Florida and you are now forced to do business with the child molesting, mass murdering jerk, because you really have no other option. That is a moment when the cost of grocery shopping, no matter what the cost of the actual groceries, becomes very high. That is a kind of peak groceries. It has little to do with the economics of the groceries. And yes, “Peak Oil” as traditionally defined is usually embedded in an economic model. This is why my suggestion of what “Peak Oil” means is different: When you (metaphorically) sell your soul to continue to obtain a resource, you’ve reached a moment in time that is very important.

The initiation of serious off shore drilling is another moment in the extraction of oil. Off shore drilling is expensive and dangerous at many levels. In the United States we shifted towards off shore drilling as our on-land deposits were worn out, and because it is somewhat cheaper (sometimes) to take nearby offshore oil than foreign near-the-surface on-land oil, and for geopolitical reasons. Those costs may not always be expressed in the “spot” prices of oil in dollars per barrel. But they are real costs.

Fracking is something that has been done for years. It is a nice trick to extract more from a deposit that has started to become tenacious. The technique is used for water, liquid petroleum, and gas. It is messy and expensive and usually results in a flow of product that soon diminishes, so whatever investment was made in the process initially does not have long term benefit. When you start fracking, that means you’ve reached one of those peaks. You are doing something you really didn’t want to do because availability or cost of the same product through other means is diminished.

The Canadian Oil Sands and other tar sands type oil has been known of for years, but it has been very little exploited. It is dirty, dangerous, expensive, and often inconveniently located. But we have been using more and more of this undesirable resource, and we are talking about using a LOT more of it in the near future. The costs of using this type of resource, aside from the continued pouring of fossil carbon (as carbon dioxide) into the atmosphere, are huge. But we are doing it. Another peak.

The alternative way of thinking about Peak Oil proposed here has the benefit of being more realistic and useful because it identifies not one peak but rather multiple peaks. Also, and this is important, one aspect of this definition of Peak Oil that is new is not to measure price or some overall measure of availability which might exclude significant costs (known as “external costs”), but rather, to identify the things we really do to continue to extract the resource. Over time we are doing more and more difficult and costly things, with many of these costs going well beyond price of the product. Such extra costs include deadly warfare and allowing governments and media to be taken over by the petroleum industry with all sorts of negative side effects that go well beyond the extraction, refining, and shipping of petroleum products.

Every major shift in strategy of access to ancient petroleum can be interrogated as a possible “Peak Oil” moment.

Yes, yes, I fully understand that I’ve strayed very far away from the usual definition of Peak Oil. But in so doing, I think I’ve pointed out a more important reality inherent in the business of extracting a non-renewable resource from the earth. A simple Peak Oil curve is the subject of a great deal of argument and speculation. The problem is, this argument and speculation tends to miss the point. We are like an addict with easy access to some drug that is highly addictive, gets you really high, is not too expensive, and can be easily obtained. Then the drug source runs dry so we seek out shadier sources and start to get in trouble. Then those sources start to dry up so we turn to different drugs with more severe health effects. But that starts to become less available, and paying for it gets more difficult so, eventually, we start rooting around under the sink for anything that looks consumable and might serve to get us high or at least, knock us unconscious. Eventually, we hit the drain cleaner. That kills us. There was not a smooth curve of availability of opium that went smoothly up and down. Rather, there was a series of shifts from a not so bad thing to a worse thing to an even worse thing to the horrid end and they find our body under the back porch where we were rooting through the recycling looking for spent cans of shaving cream.

Peak Oil is a gloss. The real story is a tragedy with several acts.

Interactive Graphic: growing fossil fuel reserves v. shrinking global carbon budget

New Oil Change International interactive graphic shows growing fossil fuel reserves in contrast to shrinking global carbon budget

WASHINGTON, DC – New analysis by Oil Change International shows that global fossil fuel reserves continue to expand while the Intergovernmental Panel on Climate Change and other scientific and industry analysts repeatedly show that our remaining budget for burning fossil fuels has shrunk to less than one third of existing reserves.

The Oil Change analysis shows that fossil fuel companies gained access to more than twice as much in fossil fuels as they produced between 2007 and 2011. They replaced the 377 billion barrels of oil equivalent (BOE) consumed and added another 415 billion BOE on top of that.

The numbers are presented in a new interactive online graphic, which can be found at http://priceofoil.org/hole

“The first rule of holes is simple: when you’re in one, stop digging. We are in a huge hole when it comes to the climate and yet we continue digging our way to climate catastrophe,” said Stephen Kretzmann, Executive Director of Oil Change International. “There is no logical reason to continue expanding our fossil fuel reserves; doing so only continues to line the pockets of Big Oil, Gas and Coal executives while putting our communities and planet in peril.”

Oil and gas companies in particular continue to spend billions to explore for new reserves, bolstered by massive subsidies from governments. Recent estimates of subsidies for fossil fuel production range from the hundreds of millions to many billions per year.

“Our governments continue to use massive amounts of taxpayer dollars to incentivize exploration for new oil and gas at a time when science is telling us we already have far too much to burn,” said Kretzmann. “It’s time our leaders put an end to fossil fuel subsidies, starting immediately by ending subsidies that encourage the expansion of fossil fuel reserves.”

Ethanol Falsehood Examined

Learning is easy. Getting it right is harder. Expunging falsehoods is hardest, but most rewarding.

There is a “meme” (using the definition of a meme as something most people in a certain community think whether it is true or not) that to produce one gallon of Ethanol for fuel you have to use some larger number (I’ve heard two, and I’ve heard five) gallons of gasoline.

In an ideal world there would be farms with giant solar collectors and wind generators. These devices would produce electricity to run distilling machines and hybrid tractors and such. On the farm would be grown GMO plants designed specifically to maximize ethanol output per acre of crop, with minimal energy input, and producing as a byproduct a carbon-trapping substance that could be spread on the fields where the GMO crop was grown, though a portion of it might be eaten by the workers on the farm some of whom might be cyborgs. Ethanol produced on this farm would thus be entirely solar, in a sense. Some of the ethanol would be used to run the farm, but there would always be a surplus. The surplus would be shipped in tanker trucks … hybrid tanker trucks charged from the farm’s solar and wind generators and using biofuels produced on the farm … to nearby distribution centers so people could fill up their flex-fuel hybrids. Oh, and the fields are covered with glass (or, better, invisible aluminum, like the clear material covering your smart phone or tablet), so water is recycled within the farm rather than lost as vapor to the atmosphere, and the growing season would be lengthened. The farm would be like a giant alga-endocrine cell chimera, with most of the energy trapping and using processes involved in the cell’s life cycle, but a reliable and abundant secretion of liquid humans can burn. There would probably be some biodiesel production as a sideline.

In that case, there would be zero “gasoline” (or whatever) used in the process of turing sunlight into human transport.

But even without that ideal cell-farm, the “meme” is wrong. It is wrong for two reasons.

First, as is the case with so much thoughtless critique of “alternative” energy forms, the comparison is unfair. If it takes X gallons of fuel (such as gasoline) to produce one gallon of ethanol, how many gallons of fuel does it take to produce one gallon of gasoline? In other words, the meme seems to assume that ethanol production is an energy-consuming process while gasoline appears spontaneously, with no energy input at all, at the point where you buy it and pump it into your car. This, of course, is not how it happens.

Anyway, all along I’ve wondered if someone should do a study that looks at the energy inputs and outputs of corn-based ethanol production, and it turns out a friend of mine did exactly this study a few years ago and never even mentioned it to me! (Well, I never asked him either, to be fair). And today, he, John Abraham, put up a blog post about this at The Guardian.

This is the blog post: Global warming, ethanol, and will-o-wisp solutions. Go and read this to find out how many gallons of gasoline it takes to produce a gallon of ethanol! (And other important things.) The abstract of the peer reviewed study done by John and his student, Fushcia-Ann Hoover is here.

Americans on Energy: New UT Study

Another poll shows increasing and strong interest among Americans in developing Green Technology and related technologies, as well as reduced interest in anti-environmental extremism and petrolatum-related efforts.

Previously, we discussed the new poll by the Science Debate people, and now we have new information from the UT Energy Poll.

The results are mixed, but interesting. In order of decreasing preference expressed by a voter to support a candidate for president based on their position, voters like expanded natural gas development1, incentives for renewable tech companies, increased energy research, requiring utilities to offer “renewable.” Those are all in the above 50% range.

Approval of a president who, in turn, would approve of the Keystone XL Pipeline sits at the 50% mark. Expanded Gulf drilling, oil exploration in the Arctic are below 50%. Loan guarantees for nuclear companies is at a dismal 28% and, happily, support for a theoretical presidential candidate who proposed to eliminate the EPA (remember Michele Bachmann?) is at 20% according to the poll.

The UT study is reported by Sheril Kirschenbaum, here.

Interestingly, 65% of poll respondents say global climate change is occurring and 22% that it is not. I believe that over the medium or short term, that is an increase in percentage of people who get that right, but it is still dismal.


1I think many people believe “Natural Gas” to be good, more or less uncritically. Probably has something to do with this.

On Sunday, I interviewed Maggie Koerth-Baker, the author of Before the Lights Go Out: Conquering the Energy Crisis Before It Conquers Us. The interview was live on radio, but you can listen to it here as a podcast.

Maggie is the science editor at Boing Boing, a journalist, and has had an interest in energy and the related science and engineering for some time. Her book is an overview, historical account, and detailed description of the energy systems that we use in the United States, outlining the flow of watts, CO2 emissions, methods of making more watts, what we use it all for, and more. Maggie focuses on the electrical power grid, which is actually responsible for more greenhouse gas emissions than internal combustion powered transport (cars, trucks, etc.), but she does touch on the latter. She focuses on the US but she draws from overseas examples in discussing what is normally done, what is not normally done, and what we might do in the future. She develops compelling and sometimes startling imagery and provides interesting and lively metaphors useful in describing and understanding sometimes very abstract problems related to making, delivering, and using energy.

Here’s the bottom line. If you want to have an intelligent conversation about energy, especially related to current problems and needs in the US and especially related to the electrical grid, you have to either know all the stuff that is in Before the Lights Go Out, or read the book before you engage in that conversation, or, if you can’t manage either of those, then maybe you should just shut up. Seriously.

I’ve been engaged in conversations about energy at a significantly heightened pace over the last several months, for various reasons, and I’ve found that the stuff that comes out of people’s mouths (my own included) is very often either very out of date or was never very correct to begin with. Maggie’s book is a very engaging way of fixing that. If you read the book, you will be caught up.

I caution those of you who might listen to the podcast that we only touched on part of what is covered in the book! You can’t just listen to the interview and skip reading the source material! Having said that, I’m not going to go into great detail here either. Listen to the podcast, get the book, read it, and report back. You will probably have interesting questions and additions to add to the comment section.
