Change comes on little cat feet

I remember when the Soviet Union collapsed. Nobody saw it coming. It even took a while for people to recognize that it did. It went out with a whimper. But soon, everybody claimed that they had foreseen it. We have a game changing change development in energy happening now. The center of energy production is shifting from the Middle East to the Americas. This will be a change almost as important as the collapse of the Soviet Empire. There are other good things happening.

There is good news on both the supply and demand side. The U.S. reached what might be called “peak demand” in 2005; since that time our consumption of oil and declined and is set to continue to decline, as we become more efficient users of oil and shift to plentiful natural gas for many uses.

On the supply side, I have written about the fantastic amounts of natural gas made available in places like New York, Pennsylvania, Ohio and Oklahoma by new technologies. Government & industry need to agree on sensible regulations that protect environment while filling our energy needs but we need to move ahead. No more blocking progress w/o giving alternatives.

New technologies are also at work with so called “tight oil”. North Dakota has become a major oil producer for that reason. It is a big change.

Beyond that, energy is being discovered or developed in friendly places close to home. Newly developed Canadian oil sands are producing more NEW oil than the total Libyan output BEFORE the revolution. Brazil has discovered vast reserves of oil & gas that may rival that of Saudi Arabia.

Alternatives are developing rapidly. Wind power, especially when coupled with natural gas, is becoming viable in some markets. Wind power’s danger to birds and bats is being addressed. Another promising development is old-fashioned biomass. In some parts of the country, especially the Southeast, wood scraps from forestry and sawmills is already making an important contribution to the energy mix. Research on biofuels is continuing and biodiesel is looking more and more promising.

Many of our new energy sources will be able to hitch rides on rapidly developing techniques in nanotech and biotech. For example, solar panels can be more efficiently made using nanotech, which can allow less expensive materials to be substituted for scarce ones. Biotech will certainly help with things like biodiesel and maybe cellulose ethanol.

I am talking about good news in energy, but there is another area of success … and challenge. Success always come with challenges, otherwise life would be boring.

The guy who came to fix my furnace a while back told me that he couldn’t find a helper willing to train and do the work despite the fact that he could make around $80,000 a year. Now I read about a shortage of skilled blue-collar workers. The American manufacturing-base is twice as big as it was in 1970, but productivity gains mean that many fewer workers are required for the greater production AND the workers left are mostly higher skilled. There just is not much grunt work left.

Since 2009, the number of job openings in manufacturing has been rising, with average annual earnings of $73,000 (reference the above link). Booming American energy production, natural gas in places like Ohio and Pennsylvania and oil in unlikely locations such as North Dakota, are already driving a manufacturing renaissance that is putting a strain on available skilled labor sources.

Americans are resilient. We respond to challenges. I graduated with my undergraduate degree in those dark times of the late 1970s. At that time, many of the experts were writing us off. We were running out of everything, they told us. Nobody would have believed back then how much we progressed in the last few decades.

America’s best days are ahead of us. We don’t need to go back, we can look forward. Despite what the pessimists told me in the late 1970s, my life has been better than my father’s. And despite what the pessimists tell me now, I know that my kid’s will have more choices than I had. We will get through these hard times and when we do all those pinheads currently crying about the end of prosperity will think that they knew it all the time.

Gas: the Simple Answer to Energy & Economy

The simple answer to our energy challenges & our lackluster economic performance are the vast energy reserves in gas and oil that new technologies have recently made available to us right here in America. This will even help keep us safer, since bad guys control much of the exportable oil and gas outside North America; the less we give them the better.

First let’s talk about our biggest challenge. Overcoming the old-fashioned ideas we learned in the 1970s. These were pessimistic times of shortages. Experts used pseudo-science terms like “peak oil” that frightened and impressed the credulous. Many thought up plans to “manage our decline.” We have less, they told us. President Jimmy Carter put on his sweater and told us to get used to it. 

The pessimists were right in the short term given their unimaginative straight line projections of resources used, obtained & projected. But they lacked the capacity to understand innovation or when they did they thought only in terms of big government investments and a managed energy economy. 

So let’s dispense with that. All those energy challenges that defeated Jimmy Carter and perplexed the pessimists have been overcome by human ingenuity. We have access to more oil and natural gas than we did in 1980 and it seems like we will have even more in the future. In the 1970s, government regulators controlled the price of natural gas and then outlawed the building of new power plants that used that clean fuel. This was logical based on their flawed information. As far as they thought, we ran out of natural gas about ten years ago and we would have, had we listened to those experts.

Supposed shortages of gas and oil playing into the world-view of some folks and they will scream when I assert they were way wrong, but they were/are. What we have today is far beyond any best-case energy scenario envisioned by the luddites of the 1970s.

Business Week has a cover story about natural gas and how it could bring the economy out of the doldrums. Cheap AMERICAN energy supplies would provide a real stimulus to the economy, one that will produce tax revenue rather than add to our debts. There are some environmental challenges, but fewer than with any of the other forms of energy we currently use on a large scale. They can be managed. 

The creation of a whole new world of energy using gas is a heroic story of individuals and small firms fighting against the experts, Federal regulators and powerful interests in places like the coal industry. They also had to fight the ridicule of experts who said that it could never be done. It is a story that shows exactly why big government programs in energy fail and often cause harm. They were going to do what they said couldn’t be done. And they did. Maybe that is why so many people STILL don’t get it. 

So let’s sum up. Technological advances have “created” vast new supplies of American natural gas that can stimulate millions of American jobs. The extraction and consumption of this fuel is more ecologically benign than any of the forms of energy it is likely to replace.  Similar technological advances have made available vast amounts of oil in Canada, but also in places like North Dakota, whose economy is booming with full employment. This will give us a North American alternative to oil from unstable places in the Middle East or Africa. So what do we do? We dither and oppose the infrastructure that will bring it to us. 

There may be no easy answers, but there are simple answers. The simple answer is to just say yes to inexpensive, available American energy, which will create American jobs, improve the quality of our air and help us pull free of the doldrums in our economy. What are we waiting for?

I have been noticing this for years. It just keeps getting better.  

No Really Green Energy

All forms of energy have benefits and risks. Inexpensive fossil fuels, for example, played a part in the remarkable regrowth of forests in Europe and the United States. (I explain below.) Of course, they also produce pollution. You have to look at the whole cycle, from production, to deployment & use to final disposal. We often see only one part. That is why it was interesting to come across an article about riots at a Chinese solar panel factory. The Chinese villagers said the solar plant was poisoning the air and water.

It seems to me that the most environmentally friendly “new” technology is natural gas. New methods have made massive quantities of this available in the United States. It is cheap; it is available AND it is American. In addition, gas can be used in existing technologies to replace coal fired plants. Gas produces very little pollution and only around 1/3 the CO2 of coal. There is no need to subsidize natural gas production or provide loan guarantees.

It is beyond my understanding why so few mainstream environmentalists are embracing gas production, which will create large numbers of American jobs. I am not saying that there are not challenges. We NEED regulations and we need to work on developing better techniques of extraction. But the idea should be to improve, not impede.

Natural gas is not perfectly clean. NO form of energy is perfectly clean, as we see from the Chinese solar plant example. Our only viable option is a diversified energy portfolio, taking into account the full life cycle of the energy source and trying to understand collateral connections. There is no one best solution and the most appropriate choices will change as society and technologies develop.

One thing for sure is that fossil fuels will remain a big, probably the biggest part of our energy portfolio for the coming decades. This is just true. We can complain about it and wish it were different, but as my father used to say, put your wish in one hand and sh*t in the other and see which weighs more. We need to recognize and work within real possibilities.

How Fossil Fuels Helped Save Forests

Forests in America and Europe reached their nadir between 1900 and 1930. Massive efforts to plant trees and the founding of the U.S. Forest Service, the discovery and promulgation of sustainable forestry methods and organization (such as the American Tree Farm System) all played crucial roles in bring back forests and avert the “timber famine” predicted by experts and leaders like Theodore Roosevelt & Giford Pinchot, among others. But equally important was a shift in demand. Horsepower provided by actual horses requires pastures and pastures preclude forests. When horses were replaced by tractors & cars, land devoted to growing feed equine transport could be converted to other uses. There was also the shift from wood. Wood was still a dominant fuel in 1900 and people cut forests for fuel. Beyond that, it is not well understood by many people, but an important collateral product of fossil fuels is fertilizer, which allows greater production on less land, leaving – again – other land free to revert to forest.

Today there are more growing trees in the U.S. than there were in 1850. Take a look at pictures from the Civil War and compare them to what you see today and you will notice the absence of forests then and their presence now. The regrowth of the forests in American and Europe is one of the biggest – and most overlooked – success stories of the latter half of the 20th Century.

One of my fears re a possible biofuels boom is that we may reverse this as land currently occupied by forests is again put into service for the intensive production of biofuel.

My pictures are not particularly related to the text. I took them today in my yard.  The top picture shows my new banana trees.  Bananas are not really trees; they are the world’s largest herb. The other picture is the tree in my yard leafing out and flowering. 

Bioenergy

Bioenergy is part of any energy solution, but it is not THE solution and the idea that bioenergy will soon make a large part of the American fuel mix probably violates the laws of physics and certainly is not justified by our levels of technology or economics. 

Oil and gas are forms of bioenergy; they are just the fossil forms. Although when we say bioenergy, we almost never mean oil, gas or coal, remembering their ultimate origin helps understand the challenge of bioenergy today.  Coal, gas & oil were once living organisms. For millions of growing seasons, ancient forests laid down these carbon-based energy riches. There is a geological period in deep time called the Carboniferous, because so many of our coal resources were laid down during it roughly sixty million. During this period, vast tropical rain forests expanded and then collapsed due to rapid climate change.  This one period and there are many more millions of years.   

When we are producing bioenergy today, we are using the product of one growing season, or at most that of dozens in the case of wood. You can see how our ephemeral efforts seem feeble in comparison to the millions of years and many trillions of life forms that produced the fossil fuels. Gasoline from fossil fuels is a superb liquid energy source that gives us more energy per gallon than almost anything else.  A gallon of ethanol yields only around 80% of the energy of a gallon of gasoline. A pound of hydrogen contains much more energy than a pound of gasoline, but hydrogen weighs less than air and a pound of hydrogen takes up more than ten times as much space as a pound of gasoline. Even with its greater energy output, a gallon of hydrogen produces only a little more than 25% as much as a gallon of gasoline.

I digress into the geological and physical facts because I enjoy such things and also to explain the origins and weaknesses of biofuels that are often overlooked. To continue with the mainstream article … 

There are many varieties of bioenergies. GMOs promise to deliver biodiesel & other forms of energy from many varieties of plants. We can already produce fuels from things like oil seeds and palm oil. Some of these things have significant ecological costs. For example, rain forests are sometimes removed to plant oil palm. These things can add more greenhouse gases than they remove.   

In the profound understanding that yesterday’s solutions are today’s problems, we should be careful, understanding that some of today’s solutions will be tomorrow’s problems.   

The most promising bioenergy that might replace petroleum is not really bioenergy at all, but rather is a byproduct. Much of our modern industrial society is petroleum based and much of that is not the stuff we burn.  Plastics, drugs, fertilizers and many composites even the paving on our streets is petroleum based.  We could replace liquid petroleum fuel a lot easier than we could do without many of these petroleum based products.  But when we recall that petroleum is a biofuel, we can see that we could use bioenergy production to replace petroleum in many of these uses. In fact, Middle Eastern potentates feel more acutely threatened by developments in alternative materials than they do the development of alternative fuels. As long as we need the “byproducts” production of oil etc is assured.  

The most famous liquid bioenergy is ethanol. Ethanol is criticized because its production can be inefficient (i.e. consume as fossil fuel as it replaces) and the feedstock is usually some form of food and/or the production of the crop for ethanol displaces a food crop.  

The first criticism can be valid. You can make ethanol from almost anything that grows in the earth, but some are less efficient than others. You have to look at the precise circumstances. The idea that it displaces food production is one of those things that make intuitive sense, but it not true.  

The displacement argument is based on a zero sum thinking that is rarely valid. A modern diversified agriculture produces a variety of crops in a variety of ways. These crops can complement each other and allow greater productivity. For example, some farmers plant sugarcane (a multiyear crop) followed by corn and then by soybeans.  One crop enriches the soil for the others.  It also can make sense to intersperse crops.  In any case, the U.S. has produced more food and feed in the last five years than in the previous twenty while simultaneously producing a bumper crops for biofuels. It works on the small scale as well. Poor farmers in Tanzania, for example, have had success in producing cassava and sunflowers, used in bioenergy along with the crops they eat. Production in general has increased, while addressing the problem of persistent energy poverty.  

Biofuel is not the same as bioenergy, which is a broader term. This is clear in the production of ethanol.  Ethanol production from sugar cane is very efficient because of the energy potential of the feedstock itself, but also because of the usefulness of the “waste” i.e. the stalks called bagasse. Burning these residues produces enough energy to completely fuel the ethanol production plus surplus energy that can be fed into the national grids. (In 2010, the EPA designated Brazilian sugarcane ethanol as an advanced biofuel due to its 61% reduction of total life cycle greenhouse gas emissions, including direct indirect land use change emissions.) 

All new Brazilian vehicles are flex fuel and Brazilians consumers have the choice of ethanol or gasoline at the pump. They make choices based on the relative prices. When the price of ethanol moves above 80% that of gas, they buy gas. Ethanol prices have been high in recent months and so Brazilian drivers have been opting more and more for gasoline, while Brazil, somewhat ironically, has been importing ethanol from the United States. The United States is both the world’s biggest consumer and producer of ethanol. Brazil is second; between our two countries we account for 87.8% of total world production. Brazil and the United States partnered to share techniques and technologies among themselves and with developing countries in the Caribbean and Africa.  

The Holy Grail of ethanol production is ethanol from cellulose, i.e. wood chips, corn husks, switchgrass etc.  President Bush mentioned this as a goal in his State of the Union speech in 2006. President Obama has reiterated this pledge. Presidents, BTW, have been making similar pledges on various technologies since Richard Nixon. Anyway, they always say the technology will be available about 5-10 years from the time of the speech. It is a good round number that allows them to take credit but largely be out of the way when it doesn’t happen.  

IMO, biofuels will never come close to replacing petroleum as a liquid fuel source. The science is still not available, but as importantly it lacks practical or economic sense. Cellulose is common in farm and forestry wastes and is “available” as a feed stock, but it also has other characteristics. Most notably, cellulose waste is bulking, heavy and it tends to burn well. It will never make practical sense to move all this stuff to factories to be turned into ethanol, a process which will produce relatively little energy in return for the massive input. The most useful alternative is what the Brazilians already do with bagasse and what many pulp, paper and wood mills do with their sawdust and scraps: burn them on site to produce electricity. This is a good use if we remember the more inclusive word bioenergy instead of the narrower biofuel.

This woody biomass is a vastly underutilized bioenergy source. If we use electric cars, it would be good if the electricity is produced from a carbon neutral source such as woody biomass. Why take the expensive and less effective extra step of turning it into ethanol?

Anyway, I see bioenergy as an important part of future energy portfolios, but never anything close to a really major solution. We just do not have enough land to produce enough biofuel for even a small percentage of our vehicles.  On the other hand, bioenergy and byproducts can form an important part of materials we use and additives in other products. For example, using ethanol as an oxygenator in gasoline makes a lot of sense – burning the stuff in pure form, not so much.

In an uncertain world, you have to try all of the above with a wide portfolio of solutions … and be ready to be flexible when some of your favorites don’t work.  

Sometimes Too Much, but Never Enough

I attended the Washington Energy Seminar at the Department of Energy over the last three days.  We had three days of talks about fossil fuels, alternatives, nuclear and conservation. It was one of the better seminars that I have attended. I wrote us some notes and will put them in later posts, but as an introduction I have to assert my belief that we do not have an energy problem that can be solved by technology, conservation or anything else. Our energy use is based on our collective and individual preferences and the options available. 

We are constrained in our use of energy almost entirely by its cost. Everything else is just commentary.  As energy becomes more plentiful, we find new uses for it.  A recent study shows that over three centuries individuals have spent about the same amount of money (relative to time and income) over all those years.  In centuries past, we got a lot less for our earnings; put another way, we had to work a lot more for everything.  In terms of light provided, candles, manufactured in the old ways, was a lot more expensive than our modern light bulbs.  People in the old days were very careful with candles.  As artificial light became cheaper, people started to find new places where it was “needed.”   More recently, we see that when cars become more fuel efficient, people drive more.  

Most of us seem to have some kind of mental accounting that tells us how much we should spend on various things. For example, we might think that $25 a week is a good amount to pay for gas.  When gas gets more expensive per gallon, we find ways to use less.  When it gets cheaper, we find reasons to drive more. The behavior change doesn’t come immediately, but it is quick. Economists call this the rebound effect. It can swamp improvements that merely conserve.  (It also, BTW, helps explain why we don’t always feel better off when we are objectively better off.)

The perhaps unwelcome but very simple lesson is that price matters. If the price of gas goes up, people seek out alternatives or cars with better mileage. If the efficiency of cars goes up w/o a price rise, people drive more to make up for it.

The big reason we have trouble conserving energy is that the human habit of mental accounting plays directly into the weaknesses and biases of our politicians, who love to pass new rules that promise cost-free solutions. I have been interested in energy and environmental issues since I was in HS, forty years ago. As long as I can remember, politicians have promised to end the energy “crises” with all sorts of calls for research, standards and breakthroughs.  Actually, whatever happened worked. U.S energy use per unit of GDP (energy intensity) has declined by about 1.7% a year for the last 60 years, better than the world average.  We have all the energy we need, but we will never have enough “affordable” energy.

The picture up top is the Department of Energy, taken from the Smithsonian Garden. It is one of those 1960s buildings. It looks better in the picture than it does in real life. I don’t much care for the concrete buildings. I prefer the nicer old brick.  The next photo is from the same spot just looking the other way. Notice it is almost spring time. It will take only one warm or two days to get the magnolias to flower.

Wind Bags

I found this about wind power. All the swells love wind power until it comes anywhere near them. They can often even get the local Indian tribes to claim it violates some sacred something or other to make the opposition more PC. Evidently it spoils the view from some burial grounds. I am not making this up. Who knew the dead were so sensitive?

Where to put it is a serious problem for any type of alternative energy. Oil and gas, for all their problems, have small & shrinking footprints on the land per unit of energy produced and it is less important for them to be near places where they are consumed. Wind, solar and biomass production are very land hungry AND because of transport & transmission challenges they are better situated near where they will be used, i.e. near people. And since some of these people will be rich & powerful, as with the Kennedys and the Cape Wind Farm, they can effectively kill many projects.

BTW – You can see from the chart nearby that the U.S. is now the world’s leader in wind energy, with more than 1/3 of the total world production. You might not guess that from all the caterwauling you hear about the U.S. falling behind in these things. Any guesses about which state is the leader?

Biofuels: Food, Fuel & the Future

Biofuels can be a part of our energy future, but are not a solution and they will never play a dominant role.  That one of the big ideas I took away from a talk on biofuels at the Wilson Center, called Biofuels: Food, Fuel & the Future. The reason we use fossil fuels is that they are so wonderfully concentrated. Coal, gas or oil represent millions of years of concentrated power of the sun captured by photosynthesis. Any crop we grow captures only one season of energy or maybe a couple decades in the case of trees. This is a fundamental limit even if we can figure out how to efficiently capture the energy stored in corn, sugar, wood, palm oil or switchgrass.

We noticed the BP oil spill because it is quick and compelling, but scientists have long known about the Gulf dead zone, a more persistently serious problem. This is a vast area of the sea near the mouth of the Mississippi where fertilizer runoff (especially nitrogen and phosphorus) have caused extravagant growth of algae. When the algae die back and decompose, it sucks the oxygen out of the water, making life for fish impossible. Much of this fertilizer runs off of corn fields. To the extent we turn more corn into ethanol, we increase this problem. We tend to notice fast developing problems like the BP spill while the slow motions ones, like the dead zones, escape notice. 

One of the dangers of something like the BP spill is that people panic and politicians and special interests take advantage. You can see this already in the calls for more biofuels and other alternatives.  Remember the cause of the dead zone in the paragraph above. But it gets worse. The nitrogen fertilizer for the corn is often derived in part from natural gas and we have to account for the fossil fuels that go into planting, moving and refining the 1/3 of the American corn crop that becomes ethanol.
 
W/o massive government intervention, there would still be an ethanol industry. It would just be a lot smaller. Ethanol has a good use as an oxygenator added to gasoline. It makes gasoline burn more effectively & cleaner. In the early 2000s it replaced MTBE (methyl tertiary-butyl ether), which had itself replaced lead as an octane enhancer a generation ago. But a little ethanol is good; a lot is less useful.  Gasoline packs a lot more energy per gallon than ethanol. As you add ethanol beyond a small amount, it begins to decrease mileage. There are also other problems related to corrosion and evaporation, but I will let anybody who cares learn about that elsewhere.
 
Suffice to say that the push to use more ethanol as transport fuel moved it from being a high end additive to extend gasoline mileage to a low end commodity. Since it is less efficient & more expensive than gas, it raised the prices. Yet the push for more ethanol continues because it is driven by politics, not by economics or common sense.
 
Let’s digress a little. You can make alcohol from almost anything that grows on earth. You can see that from the vast array of alcoholic beverages available worldwide, made from potatoes, corn, cactus, grapes, apples and even watermelon. But it is easier to make ethanol from some things than it is from others. It is relatively easy to make ethanol from sugar cane. That is why Brazil has an ethanol advantage. It is significantly less efficient to make it from corn and so far prohibitively expensive to make it from cellulous (i.e. switchgrass, wood chips etc).     

The U.S. does not have a competitive advantage in making ethanol. For one thing, corn is not a great feedstock and to make that worse we (the U.S.) has a relative advantage growing corn as food for man and beast, but when we make it into ethanol, we manage to negate our natural advantages, converting a product we do well into a product that we do merely okay. Beyond that, corn ethanol tends to be produced near where corn grows, i.e. in the middle of the country. Much of the demand for liquid fuel is on the coasts.  Ethanol cannot be transported via gasoline pipelines because it is corrosive and tends to create evaporation problems. Transporting ethanol by road and rail is relatively expensive. On the other hand, ethanol from Brazil is cheaper and closer – in terms of transport – because it is produced near ports in Sao Paulo state and can be easily sent via sea transport to places like Norfolk. That is why we have to subsidize ethanol production in the U.S.  by $0.45 a gallon AND put a tariff of $0.54 on ethanol from Brazil.  

In other words, public policy is pushing us toward one of the most expensive energy alternatives made even more expensive by public policy.
 
What about cellulosic ethanol? This can be made from materials that now go to waste, such as forestry waste or stalks and sticks from crops. We can also easily grow some crops, such as hybrid poplars or switchgrass, specifically for energy. The biggest problem is that we still cannot do it efficiently. Nature has been evolving for millions of years to prevent wood from easily being converted (i.e. fermented or rotted).  There are better alternatives. The more you have to process something, the more costs you add.  Wood chips, for example, CAN be turned into ethanol. But it is a lot easier to make them into pellets or burn them directly to make heat or electricity.

The problem is liquid fuel. Gasoline makes great liquid fuel and alternatives cannot compete. Direct government attempts (such as subsidies and mandates) to change this equation don’t work well for that reason. Beyond that, alternatives and gasoline are locked in a feedback loop. If alternatives, such as biofuels displace a lot of gasoline, the price of gasoline drops relative to the biofuels in question, making them less competitive.

Government has a role, but it is supportive and indirect. Government should not try to pick particular technologies. The ethanol debacle should have taught us that. It can help with infrastructure and basic research. Real, sustainable gains come from increasing productivity that lowers costs or costs of doing business, rather than tries to pay them down with taxpayer money.

A final interesting concept they talked about at the seminar was “peak gasoline.” People talk about peak oil. Peak oil is the theoretical spot where we have used up half of the petroleum available on earth. It is a slippery concept that is meaningless w/o specifying a price. At $5 a barrel, we reached peak oil years ago. We may never reach peak oil at $500 a barrel.  Peak gasoline is an easier concept.  Given the changing nature of our society, our driving habits and mileage efficiency, we probably reached the maximum amount of gasoline we will ever use. We cannot expect consumption to rise forever. Consumption is already dropping. Of course, we have not and may never reach “peak energy.”

There will be no magic solution to the energy problem. We choose our energy portfolio based on cost, convenience, availability and mere preference. This is how it will always be. It is an ongoing situation, not a problem that can be solved. No matter what elegant and wonderful solutions we devise (and we will come up with some) we will still be talking about the same sorts of things fifty years from now.  It is good to remember – despite the current pessimism – that our energy situation is better than that of our ancestors in terms of the amount of work we need to perform for each unit of energy. But as energy gets easier to get, we want more of it.

The picture up top is the inside of the Wilson Center. In the middle is the outside of the of the Reagan building, where the Wilson Center is located. In the lower middle is a sign warning that if you step on the grass, motion activated sprinklers will flow. It is an idle threat. I tested it and stayed dry. 

Gassy Good News on Energy

The energy news is so good and so comprehensive that it is hard to believe. The federal Energy Information Administration reported last week that greenhouse gas emissions fell 7% last year—the largest- percentage and absolute decline ever. The U.S. carbon footprint has shrunk in three of the last four years. The bad news is that the recession caused some of last year’s decline. However, we managed a 1.3% decline in 2006, the only time this happened during a time of robust economic growth. But we can expect more good news. Our energy intensity (i.e. the amount of energy it takes to produce a unit of GDP) has been improving for many years. Last year it improved by 2%. (You probably have not heard about this improvement either, since it didn’t require new legislation to make it happen and much of the media cannot seem to perceive any positive developments that take place w/o government fiat. If the energy bill had passed, you would have heard a lot more, as they would be taking credit for this number.) And carbon intensity will drop even more. Abundant American natural gas supplies are going to help us reduce U.S. CO2 emissions and allow us to give people like Hugo, Mahmoud and Vladimir a good kick in the kiester, just when the international bad guys thought they would be able to set up a gas cartel similar to OPEC.

are subjects I like (so please excuse me if I go back to the same wells) and I am optimistic that we can solve our problems, or more precisely overtake them, since few problems are ever solved and when old problems go away new ones come. The pessimists keep on telling us we are about to hit the wall, but the innovators keep on finding ways around or through the troubles, often despite the experts.

The pessimistic “experts” can create serious problems, however. For example, back in the 1970s experts said we were running out of natural gas, so the Federal government banned new power plants run on gas, in order to save it for home heating etc. (President Reagan repealed the ban in 1987.) Three Mile Island, the disaster that killed nobody, managed almost to kill the nuclear industry. That is why we are behind on gas and nuclear power stations today. Instead of nearly zero carbon emission nuclear power and low carbon emission natural gas, various government agencies and environmental action groups pushed us into using more petroleum and coal. Go figure out the unintended consequences.

But this is supposed to be a happy occasion. Let’s not bicker and argue over who killed whose program. We have more options than we thought we did and let’s use them wisely.

Natural gas is the cleanest burning of the fossil fuels in terms of CO2 and ordinary pollution. You can understand this when you are cooking your food with gas on your unvented stove. What if your stove and oven ran on coal or oil?

Gas is also relatively clean to extract. A natural gas leak does not spread over the oceans and kill animals and plants. Miners don’t descend into dark pits to pull the stuff out, nor do they remove the tops of mountains in West Virginia to get at gas seams. The environmental danger with natural gas is relatively small. The biggest problem is that gas extraction using the latest techniques requires the use of water and there are some concerns that local water resources could be impacted. So far this has not happened on a large scale, but gas production should be properly regulated.

Maybe it was a divine joke to put most of the world’s exportable oil under unstable and sometimes plain nasty regimes. Or maybe it is just true that the concentration of a resource like oil, which requires little input and almost no actual work from the people under whose land it is found, is the problem. Easy and/or unearned concentrated wealth encourages klepocracies. Maybe the best thing about natural gas is that it is widely distributed and a lot of it is right here in America. While gas won’t put petro-tyrants like Ahmadinejad of Hugo Chavez out of business, it will – it already has – diluted their power.

So let’s get cooking with gas while we develop alternatives to fossil fuels. As long as I can remember, solar and wind alternatives have been “around five years” to viability. It has taken longer than we thought, but progress is being made. The largely unanticipated jump in natural gas reserves has bought us some time. We can meet our environmental goals, while kicking the despots, dictators and jihadist in the keister (as I mentioned above) and do all this w/o crippling our economy.

Gas is not a permanent solution. There are no permanent energy solutions. Our technology and innovations have saved us for another generation and we will live to fight the energy battle another day. By then we will be better equipped to win, but only if we continue to innovate now.

Windy Energy Alternatives

It has been very windy today and I can understand why they built all the windmills as we drove through the forests of them to get from the coast to Palm Springs. 

Wind power was the topic of NPR’s Science Friday a few weeks ago, this time from Oklahoma. If you read between the lines, you understand why alternative power is still alternative. When one of the producers of wind turbines was asked why he wasn’t selling more in windy Oklahoma, he honestly responded that electricity rates were too low. His turbines couldn’t compete with the stuff from the grid. There’s more.

I generally favor a diverse portfolio of energy. I am especially fond of biomass fuel, specifically wood chips. But I recognize that even with this simple and well-known fuel there are problems. The biggest challenge to almost all fuels is that they are not where you need them to be. I have acres of wood literally rotting away, but gathering it up and transporting it cost more than it is worth.

What annoys me about some of the alternative fuel advocates is their unjustifiably smug attitude that they have found some big thing and that the only reason it is not widely used is because everybody else is stupid or “big companies” are too greedy to allow it. Besides overlooking obvious drawbacks in the fuels themselves, they are almost always overlooking costs and troubles of transport and distribution. They sort of assume these are free or should be covered by someone else.

So let’s talk about wind power. Wind is free; capturing it is not and neither is getting it from where the wind is blowing to where the energy it produces will be used. A caller to the NPR program talked about getting off the grid with wind power. The guy who sells the turbines admitted that you really need the grid. Wind is unreliable and if you wanted to be off the grid, you would have to invest around $100,000 for all the back-up systems you would need to keep the lights on. The grid costs money to build and maintain. If you account only for the cost of the turbines, you are missing the biggest investments. It is like the kid who thinks he pays the whole cost of a car by filling up the gas tank on weekends.

Most people will not have their own wind turbines. That means that the turbines will be some distance from the consumers. The wind blows mostly on the plains and in the ocean, far away from cities and factories. So we need transmission lines. But we need more than the kinds of transmission lines we have already. Big power plants need transmission lines, but they are at least coming from the same place. Wind turbines are by necessity spread out. You need transmission lines from the wind farms to the cities, but you also need lines between and among the turbines.

Transmission lines are not free and they are not 100% ecologically benign. Each time you build transmission lines, you also cut through the environment, across streams and migration routes, to build roads to service the line and you build pylons every 100 yards. That’s a lot of rock, steel and concrete when you add it up over many of miles, not to mention lots of gas burned by crews building, checking and maintaining it all. So when anybody tells you that a wind farm takes up only a couple acres, recall the many miles of transmission lines. I personally have eight acres under power lines. I can’t grow trees there and while I think it is good to have it as edge community (it can be managed as excellent quail habitat) too many of these kinds things will fragment environments.

The fact is that we use carbon based fuels because they are cheaper, easier to move and more convenient to use than alternatives. When alternatives get to be cheaper, easier and more convenient, they stop being alternatives and just get to be mainstream. That is what it means to be a viable alternative. As long as earnest advocates have to try to convince skeptics about its virtues, it is not viable. Energy consumer really aren’t that dumb. When something really is cheaper and easier it won’t take earnest advocates; they try very hard to get more of it.

Wind, solar and other alternatives are indeed getting cheaper. When their time comes, there will be no stopping them.  (I assume that the wind turbines we passed make some money.)  Until that time artificially pumping them up won’t really make it happen. And we have to remember that no form of energy is trouble free. There are always trade-offs.

Energy: Cheaper in the Long Run

Technology is amazing. In the last few years, new technologies have vastly increased American reserves of natural gas and are making North Dakota a leading oil producer, so much for peak oil. The term “game changers” is thrown around in both these cases. I might paraphrase the Godfather about fossil fuel, “Just when we think we’re out, technology pulls us back in.”

Environmentalists have been predicting the end of the age of hydrocarbons ever since I was a kid. Their predictions have a kind of plaintive, even pathetic tone, sometimes a hopeful one. Actually, the resource depletion prediction is a lot like the old Malthusian predictions and wrong for the same reasons. They have consistently made their predictions by simply projecting past trends forward and assuming limited technological progress. In other words, they underestimated the power of human intelligence, innovation and imagination. As Yogi Berra used to say, “Predicting is hard, especially about the future.” It is just impossible to predict discontinuous changes but we are usually aware of things that could go wrong with what we already have.

Back in the 1970s experts predicted that by now, or more commonly by around 1980 or 1990. Yet we persist. Usually such successes would be all to the good. We really don’t have to worry about running out of energy and we can probably expect real energy prices to drop in the next decade. What is not to like? Nothing, except the potential problems of global warming. The problem with switching to alternative energy is price. It has always been price and will always be price. Until people talk about price, it’s only some people talking. As long as fossil fuels are cheaper, they will be preferred. Why would a rational person choose to pay more to get less convenience? Petroleum based fuels such as diesel and gasoline, for example, are nearly perfect fuels for a car. They are very dense (i.e. a lot of energy per gallon. Hydrogen has more energy per pound, but it has such low density that takes up more than three times the space; ethanol is much denser than hydrogen, but not as dense as gasoline and less efficient). Natural gas is great for stationary energy production. It is very clean burning, easily distributed via underground pipes & remarkably efficient.

So let’s be clear. The reason we rely so much on fossil fuels is that they are generally cheaper than the alternatives, convenient to use, easily produced and readily available. When you pit low price, convenience and availability against something that cost more & is harder to use, which do you think wins most of the time? This is the place for some government intervention in the form of a carbon tax . Prices of carbon based fuels will naturally DECLINE as technology increases exploitable reserves. As the prices of carbon based fuels declines in real dollar terms relative to other products, we should tax them back up. The ratchet is a relatively painless way to phase the tax in.

Lest this become merely another source of tax and government waste, we should make this a revenue neutral venture. A good idea here is tax plus dividend. Whereby ALL of the new taxes collected on carbon would be paid out the individual Americans as dividends. To make it simple, every American man, woman or child alive on Dec 31 would get a check for whatever the tax revenue divided by the population. I would make this clean and honest. Everybody gets an equal piece of the action.  I  don’t think politicians will go for it, since it cuts out their opportunities to turn the money to their own purposes, but it is a good idea and if we are serious about addressing climate change, raising the price is one of the only things that really work.
