Matt at http://think.fernsehtek.com issued a challenge to auto manufacturers. He wants more choices, real alternatives, when it comes to personal transportation. He’s got a legitimate beef. Oil is expensive, it beholds us to countries that have more of it than we do, and it will run out. We’re not close to running out right now. Despite the Chicken Little cries of “The sky is falling!”, the fact is we haven’t even reached peak production, which is the theoretical point at which production will decline irrespective of what new technologies are applied to all proven and probable reserves. In my research, I’ve discovered that nearly all credible estimates put the running-out-of-oil risk at between 80 and 120 years. This is interesting, but it misses the point, I think.
For all practical puposes, oil is a finite resource. Technically, it gets produced through extreme pressure and and heat combined with the decomposition of carbon based compounds. Live stuff that dies can get turned into oil, but the time it takes to go from dead dinosaur to barrel of oil is so long that we can only count on what exists in the ground right now. Matt is the geologist, so I’ll leave the specifics to him. The important point is that we are using it faster than it can be created. Classical economic theory dictates that as supply decreases, price increases; as demand increases, price increases. In fact, the expectation of an increase in demand or a decrease in supply is more than enough to push up the price of something as critical to modern life as oil. This is the crux of the problem.
Modern society cannot exist without oil. Take away petroleum and you turn back the clock 100 years. Everything, and I mean everything, rotates around oil: transportation, power and electricity, agriculture, specialty chemicals (including pharmaceuticals)…the list goes on. Can you even imagine a world without something as simple as plastic? This gives those gifted with vast reserves of oil an extraordinary amount of influence on those who use oil. In an added twist, and as a cruel joke by God, most of the world’s most easily tapped reserves of oil and natural gas are located in the most sociopolitically unstable areas on the planet: the Middle East, Russia and the former Soviet republics, Mexico, and Venezuela. These are not the countries that you want pulling the strings. Oil is the biggest string of all and it’s tied to everyone. If any of these countries were able to get their shit together at all, or worse yet, get their collective shits together, they would wield incredible influence over national and global economies. Oil is so incredibly important to the functioning of the modern world that even the implied threat of a decrease in supply or an increase in demand sends shockwaves through the spot and future pricing of oil and natural gas.
A shitty situation, to be sure. What are the options? There are actually a lot of options, but physics and chemistry limit most of their practical applications. Ethanol has gotten a lot of play lately because it can be created from renewable foodstock; typically corn in the U.S. and cane in Brazil. There are a lot of problems with ethanol, both as an energy source and from an environmental perspective. Ethanol has about 50% of the energy density of gas, so you have to burn twice as much for the same power output. This completely eliminates the cost benefit versus oil. It accelerates corrosion of metal and eats away at many types of rubbers, making it a challenge for existing powerplants. In the U.S., the ethanol boom diverted huge portions of corn crops away from foodstock and into fuelstock. Farmers converted from other types of crops to corn because of the demand for and subsidized economics of ethanol. This drove up the price of not just corn but of all foods, which disproportionately impacts the less fortunate. Finally, when you consider all of the gas burned in the farming of corn, plus the environmental impact of increased water usage and fertilizer usage, suddenly ethanol doesn’t look so good. Through subsidies and poorly considered legislation, the government, once again, created a case study for unintended consequences. Without the subsidies and other mandates, ethanol as a business could not exist.
What about wind? Wind power has been around for a while and is pretty well understood. So are the economics of wind, and they suck. Again, even with substantial subsidies, the marginal cost of wind is greater than that of gas, oil, or coal. As a result, commercialization is unlikely until carbon based fuels become much, much more expensive. The problems with wind are pretty simple. The energy density is very low, some of the best places to generate wind power are furthest away from the greatest electricity needs, and wind is not terribly consistent ant or predictable, creating a timing mismatch between production and usage. Right now, wind accounts for about 0.1% of our electricity production. Our President has been vocal about doubling this in the near term. Big deal…0.2% of the electricity produced. I believe the Texans refer to this as ”Big hat but no cattle”. Wind farms are HUGE (ever driven through the Central Valley in CA or the Mojave Desert?) but produce very little power and the power is not reliably available. Wind farms boast about 35% efficiency, mostly because wind doesn’t always blow. When it does blow, it is often during off-peak usage hours and battery storage is still in the dark ages, relatively speaking. None of this was factored into the equation when the administration crafted its energy plan. It will pour billions of taxpayer dollars into an energy black hole that will have essentially no impact on our power needs or the environment, but is politcally saleable and expedient.
Surely hybrid and electric cars are the answer, based on all the commercial and government sponsored hype. Sadly, no. Battery technology is still terrible. The energy density of even the most sophisticated battery is way, way to low for electric cars to be a viable alternative for most drivers. Even cutting edge battery companies like A123 (disclosure: financed by my firm) are introducing batteries that are better marginally, not by the order of magnitude needed to make electric cars a real alternative. Electric cars simply can’t go far enough on a charge and take too long to charge up to be practical. The physical and chemical limits on batteries are well known are very real. It is very unlikely that in our lifetime we will see this change. Another problem with batteries is that they need to be charged and that electricity needs to come from somewhere. Right now, most of it comes from coal and gas. Unless we start charging electric cars with solar and wind, not much, if anything, is gained. The one real advantage is that energy generated on a large scale centrally and then distributed is much, much more efficient than energy generated locally (in a car engine, for instance). This is a clue to the potential solution to our energy conundrum.
Hybrids are a bit like fools gold…shiny and enticing but not really worth shit. The battery issue is a big part of this failing. They restrict the practical advantage of a hybrid system and they are very expensive. In real world driving tests, not the completely unrealistic EPA methodology for determining fuel efficiency, time and again it has been shown that hybrids are barely superior to high efficiency gas engines in like-sized cars. Hybrid cars are much more expensive than their gas-only counterparts and, again, can only exist commercially with government subsidies in the form of tax breaks. The discriminating buyer will do the math and discover that even with the tax break, the breakeven point on a hybrid will not be achieved by most owners, especially on a time-value-of money basis. Once more, we will piss away money on something that will not have an impact on either oil consumption or the environment. Not smart.
Practical solar is so incredibly far away it’s not even worth talking about. It is incredibly inefficient and would require millions of acres of photovoltaic cells to have any impact whatsoever. This will have environmental implications. In addition, the timing mismatch/storage problem exists for solar. Even the most bleeding edge solar technology is a decade away from being efficient enough in converting sunlight to electricity to be considered a real alternative. The cost per watt issue here is worse than wind and ethanol. Another option that can’t survive without subsidies and won’t make a difference in the near or mid-term (or the long term, most likely).
Water is very well understood and actually stacks up well, cost per kilowatt. I know much less about water power than the rest because water is usually an infrastructure play versus a technology play, so I and my firm have much less exposure to innovators in this field. My rough understanding, though, is that pretty much every river in the U.S. that can be dammed has been dammed. The environmental impact of damming a big river should also be considered. The Three Gorges Dam in China is an environmental and social tragedy (but it is an engineering marvel).
After reading through 1,500 words, you’re probably saying, “What’s the point of all this?”. I started off by saying that Matt was right. We are much too beholden to oil for a bunch of different environmental, political, and economic reasons, and we need to address this now. It will come as no surprise to anyone that I support a market based solution. For any option to catch fire, it needs to produce energy at or below the cost of carbon based fuels, the energy needs to be reliable, scalable, and producible on-demand and without the timing mismatch of wind or solar. If these conditions don’t exist, no amount of subsidies will force the issue, but these subsidies will drain valuable capital and resources away from better uses in the quest to find power that isn’t subject to the Three Laws of Thermodynamics (not going to happen).
There are a lot of very interesting things going on right now on the technology front to address our energy concerns. All of the best stuff is focused on centrally produced and distributed power since it is so much more efficient than locally generated energy. Companies like Silver Spring (disclosure: financed by my firm) are technology based infrastructure plays that tie together usage and production, allowing producers to quantify usage and charge more during peak hours and allowing users to understand usage at the level of the appliance, as well as pricing, so that they can tailor usage to need and cost efficiency. The system provides market feedback to both the producer and the user to incent conservation and efficiency (Congress, are you taking notes for application in healthcare reform?). None of this requires tax dollars. In fact, the ROI on this technology is so clear and compelling that utilities are falling over each other to both purchase the technology and invest in the company. Better for the taxpayer, better for the consumer, better for the environment, plus it creates jobs, advances the state of technology, and will create wealth for the investors.
Nuclear power is an option that should be getting much more attention, but isn’t. Some of the slight is earned but a lot is irrational, in my view. What to do with the waste is a very real and big problem. It’s nasty and it lasts a very long time. The state, local, and federal governments put the kibosh on the Yucca Mountain underground storage facility in Nevada. There was a lot of technical stuff that factored into the decision, but it really was a clear case of NIMBY. The problem is, the proposed facility really wasn’t in anyone’s back yard. Everyone supports sacrifice for the greater good as long as it isn’t them being asked to sacrifice. Short sighted, I think. I get it, though. I wouldn’t want that shit in my town either. But as a friend of mine once said, places like Northern New Jersey need to exist so places like Connecticut can exist.
Nuclear still suffers from the stigma of Three Mile Island. In fact, this one event basically killed the construction of all new nuclear facilities. I was pretty young when that went down, but I still remember the headlines and the fear. The fact is, the radioactive release was extremely minor and there has been no statistically identifiable health or environmental impact from the incident. New plant designs are generations ahead of the Three Mile Island facility, in terms of safety. What happened then (which was a perfect concatenation of a series of small errors that would probably happen once in a thousand years) almost certainly couldn’t happen with these new plants. They are so much safer, and yet the odds of ever getting the necessary permitting to build one are so long that no firms are willing to put up the risk capital. The current administration has basically shut the door on nuclear fission. Given the clear advantage of centrally generated power, the incredible energy density of uranium, and what I understand to be an abundance of uranium in the U.S. (Matt, is this true?), I think we have made it our nation’s policy to ignore an important and viable alternative to carbon based energy.
If the government does absolutely feel the need to spend our money on energy, they should forgo wind and electric cars and pour it into investments in private companies trying to untie the Gordian Knot of nuclear fusion. Fusion is the Holy Grail of energy generation (Thermodynamics tells us that we can neither create nor destroy energy, but merely change its form). The power created from fusion is relatively clean and basically limitless, as it is fueled by the most abundant element in the universe, hydrogen. Unfortunately, right now, fusion is still very much a science project. To induce a controllable fusion reaction that is self-sustaining (that is, generates as much power as it takes to maintain the reaction) is a very difficult problem to solve and we are only at the very beginning of finding a solution. I probably won’t live to see it happen. But, and this is important, we know that it is a solvable problem. It’s basically an engineering puzzle at this point. The physics are completely understood.. Once we solve the puzzle, the answer will be completely game changing. This is the type of innovation that is worthy of public finance: a clear end-point with a result that will have a significant and meaningful impact. It will end our dependency on oil and, if we solve the problem first, will cement the U.S.’s economic leadership for generations to come. Compare this to the money being spent on technologies that aren’t commercially viable and won’t make a meaningful impact on usage, carbon footprint, or any other metric.
Fuel cells are another very interesting technology with great promise but with big engineering challenges to overcome. Right now, it appears that fuel cell technology may be very useful on a small scale (phones, computers, small cars) but may be tougher to implement for centrally generated power. Stay tuned. There are a lot of very sharp minds and smart money focused here.
What to do in the meantime? Good old fashioned conservation. Carpool, buy smaller cars and drive less, turn down your thermostat, shut off lights, convert to mini-flourescents, insulate your house and install better windows, WebX conference or telecommute instead of hopping on a plane; these are things we can all do that will stave off oil dependency and help the environment. Don’t be suckered in by pie in the sky promises of abundant energy with no environmental impact at a low cost. It doesn’t exist. In physics, there is no free lunch, and it is a zero sum game.
