Are Biofuels the Answer?

As the price of oil rises toward the $100 per barrel mark—and American motorists see more of their income burned at the pump—finding alternative sources of energy has become a major issue. An increasing number of consumers, many of them of the "green" variety, have opted for hybrid cars like the popular Toyota Prius and the Honda Civic and Accord hybrids. American manufacturers have jumped into the market as well, producing such hybrid vehicles as the Saturn Aura and the Ford Escape.

Hybrids are just that, a synthesis of two separate technologies: the internal combustion engine and the electric motor. The modern hybrid uses an efficient gasoline engine as its primary power plant, with the electric motor providing extra power when needed, as well as being able to run the car exclusively—say, in slower city traffic—for even greater efficiency. The 2007 Prius, mid-range in price among hybrids, costs about $23,000.

However, because the modern, industrial economy runs on oil, many movers and shakers want to solve the problem at the source—not by making vehicles more efficient, but by making fuel that is more affordable and renewable. At the same time, they hope that this fuel will also be more environmentally friendly and decrease our dependence on foreign supply. To many, the answer is biofuel.

Biofuel, known as "agrofuel" to some, is any kind of fuel made from biomass—organic substances. The most common biomass crops are corn (maize), soybeans, and sugar cane, although such things as sorghum, hemp, cotton, various grasses, sunflowers, cassava, potatoes, rice husks, wheat, as well as animal fats, food waste, manure, and waste wood have or are being used to produce biofuels. To make ethanol, also called ethyl or grain alcohol, enzymes are used to release sugars from stored starches in the biomass. The extracted sugars are fermented and distilled to produce an alcohol, which is then "dried" or de-moistured, leaving a highly combustible liquid that can be used alone or mixed with gasoline in any ratio.

Most gasoline engines on the market today can use up to about 10 percent ethanol when blended with gasoline (called E10). Because ethanol corrodes components containing iron, any higher ethanol mixture requires modifications to the engine, which are found in the "flex-fuel" vehicles now being sold by several manufacturers. The Renewable Fuels Association reports that the United States produced 4.855 billion gallons of ethanol in 2006, while U.S. demand topped 5.37 billion gallons. (Current ethanol statistics can be found at http://www.ethanolrfa.org/industry/statistics/#A).

While ethanol would seem to be a sure bet, it is inherently less efficient than gasoline. Since pure ethanol (E100) contains about 34% less energy per unit than gasoline, its use will result in a 34% fewer miles per gallon (MPG). Even in E10, MPG is reduced by 3%. Lower fuel mileage means more frequent refueling and thus higher cost. According to National Geographic (July 2007), a motorist who drives a gasoline-powered car may pay $3.03/gallon, but the owner of a flex-fuel vehicle that uses E85 (85% ethanol), priced at $2.62/gallon at the pump, will actually end up paying $3.71/gallon for an equivalent MPG.

Ethanol is also touted as a more energy-efficient fuel on the production side than petroleum. For instance, proponents say that for every unit of energy used to produce ethanol, there is a gain of 1.34 units of usable energy. By contrast, they claim, petroleum's "energy balance" is a dismal 0.805 units, a net loss of energy. However, if that were so, it would be unprofitable for oil companies to bring petroleum fuels to market.

It turns out that these two figures are apples and oranges, as they are calculated on different bases. Using input versus output BTUs (a unit of heat energy), the energy return on energy invested for gasoline is about four times better than for ethanol (5:1 vs. 1.27:1). Crude oil as a whole (which includes many other fuels besides gasoline) has a total energy return of roughly 10:1.

While ethanol promoters use "reduced dependence on foreign oil" as a major selling point, the underlying motivation is environmental. Ethanol is indeed produced and burns cleaner than gasoline, and it is made from renewable substances. Despite these commendable factors, ethanol comes with two major downsides: 1) It is terribly expensive to convert a fossil-fuel-based economy to ethanol; and 2) it requires that vast swathes of fertile land be switched from growing food to producing biomass.

Put differently, its advocates are more concerned about being environmentally friendly and sustainable than about either the nation's economy or, more importantly, feeding its citizens inexpensively. Too high fuel and pollution standards could stall America's economic engine, and diverting food supplies to make biofuels will certainly inflate food costs. One-fifth of the U.S. corn crop is already being diverted to fuel production, leading to a doubling of the price of corn. As a staple crop, corn prices affect a wide variety of food industries, such as beef, pork, and poultry producers; cereal and snack food makers; and vegetable oil manufacturers, among others. At the end of the line, the consumer takes the biggest hit.

Are biofuels the answer? Not yet—and they may never be. Like solar and wind power, they are certainly not silver bullets for our energy woes. Oil is still the king of fuels, and world events will continue to churn around those nations that have it and those that do not. Today's—and tomorrow's—superpowers will run on Black Gold, and oil fields and oil production centers will remain major prizes in the run-up to the return of Jesus Christ.

What's in It for Us?

While in college, I took a yearlong course in International Relations under Gene Hogberg, news editor of The Plain Truth magazine. One of the primary ideas he hammered into his students is that an observer of the world scene must always remember that nations act out of self-interest. In other words, nations only do what will benefit them. It is a rare—indeed, almost unknown—thing for a nation to sacrifice its own well-being to help another nation. On the surface, the American interventions in the first two World Wars seem to be exceptions to this rule, but in both cases, America's entry into those conflicts occurred after careful calculus. The United States sacrificed a great deal in men and materiel in those wars but gained so much in international power and prestige that these sacrifices were considered by its leaders to be well worth it.

If a person has a firm grasp on this principle of self-interest and what a nation considers to be good for it, he can forecast with a fair degree of accuracy what a nation will do. For instance, had the Soviets been more astute in this area, they might have been able to hold out longer against the U.S., and perhaps against Ronald Reagan in particular, during the Cold War. Though the Kremlin may have had intelligence that Reagan was of a different stripe than his predecessors, it did not believe that he was considerably different. Specifically, he was different in that he was not satisfied with détente or containment but desired to defeat the U.S.S.R. so soundly that it could never recover. In short, America's national interests shifted once Reagan became President, and the Soviets missed it. Once they did, they had lost the Cold War.

In coming to understand the U.S. position in the latest Israeli-Hezbollah conflict, this principle of self-interest must hold a prominent position. Just what is America's interest in this war? What are its interests in the region? What does America hope to gain among its "peers" (Britain, Australia, Canada, France, Germany, Russia, China, Japan, etc.) by its stance? These are not easy questions to answer, but considering them helps to clarify matters. Let us begin with a few corollary principles:

First, in determining national interests, actions speak louder than words. A raw, historical example of this is Adolf Hitler's 1938 "peace in our time!" agreement with British Prime Minister Neville Chamberlain. The agreement had come about as a result of Hitler's aggressive annexation of the Sudetenland, and any impartial observer should have seen that the German Chancellor would not be satisfied with just a small part of Czechoslovakia. It was well known—even on Downing Street and in Whitehall—that one of his chief aims for Germany was lebensraum: "living space." Nevertheless, Chamberlain believed Hitler's smooth promises, and Europe was plunged into World War II in 1939. Thus, smart observers of the world scene remember that diplomatic language is, frankly, 1) vague, polite speech designed to say nothing, or 2) bald-faced, but courteous deception.

Second, follow the money. National power cannot be maintained except by mass infusions of wealth. All wars—and probably just about all other national decisions—have economic justifications. Thomas Jefferson has a reputation, as the writer of the Declaration of Independence, as being a foremost defender of the U.S. Constitution and an advocate of limited federal government and states' rights. However, he was willing to throw his reputation to the winds to buy the territory of Louisiana from Napoleon for what was then a huge sum that the strained national treasury could not handle. His unilateral decision was made on almost purely economic grounds, as the Louisiana Purchase doubled U.S. territory and increased its potential wealth exponentially. It was in America's interests, the Constitution be hanged. Today, oil plays a premier role in Middle Eastern geopolitics, as the whole world runs on the stuff.

Third, a balance of powers provides more advantages than unequal powers. As an interested geographically contiguous nation, Britain played this game in Europe for centuries. If the French became stronger than its neighbors, the British would ally themselves to the weaker nations to keep France in check. If the Spanish gained hegemony, Britain would align itself with Spain's enemies. If Germany ascended to greatness, Britain supported those opposed to the Germans. Though it appears complex diplomatically and militarily, this balancing act provided Europe with a fair amount of stability—at least enough to keep one power from becoming dominant and thus imposing its will on the others. For Britain, it opened marketplaces to its businessmen and helped it become a world-spanning empire. The U.S. is playing similar games today as the world's lone superpower. In this vein, remember the old axiom: War is just politics by other means.

So, then, what is America interested in vis-à-vis the current crisis in the Middle East?

My take is that the White House welcomes this war and supports Israel for several reasons:

  1. It does not mind if Hezbollah, an arm of Iran, is mauled, as this is a way to strike back at the ayatollahs for their recent belligerence.
  2. It wants Israel to be slightly dominant in the region to counter the nearby Arab nations, taking some of the weight off America's military.
  3. It actually welcomes the instability this conflict causes because it takes pressure off its operations in Iraq and some of its domestic problems.
  4. It knows that because the region's turbulence continues, its presence will be necessary for many years, ensuring America's access to Middle Eastern oil.

Internationally, it is willing to take some diplomatic heat for being slow to intervene in order to drive the point home that the Bush administration's methods of handling situations like these (methods that the Israelis also employ) work. Put negatively, the U.S. is sticking its finger in the international community's eye (specifically, the UN's).

This analysis may be all wet, but it is considered under these principles. What God may have in mind may be altogether different (Psalm 2:4-5; Isaiah 40:15-17, 22-23; 48:3).

What We Don't Know

During its approach to a mooring mast at Lakehurst Naval Air Station in New Jersey on May 6, 1937, the German dirigible Hindenburg, filled with hydrogen, went up in flames in less than a minute. Thirty-six people—13 passengers, 22 crewmembers, and one member of the ground crew—died in the disaster made famous by a newsreel dubbed with the radio commentary of eyewitness Herbert Morrison. In it, he uttered the well-known cry of despair, “Oh, the humanity!”

It is commonly thought that the Hindenburg conflagration killed the majority of those on board, and the newsreel footage certainly makes such an assumption plausible. However, only a little more than a third died in the disaster, as there were 97 people aboard the giant airship when it ignited. In addition, most people believe that these deaths were caused by the terrible fire, seen so vividly against the evening sky in the film, but this, too, is a myth. Most of these people died because they jumped to the ground in their fright.

In a sense, what they did not know, or failed to realize, killed them. Hydrogen, being the first element on the periodic table, has an atomic weight of one. As such, it is lighter than air, composed predominantly of heavier nitrogen and oxygen, so when it combusts, the explosion and flames shoot upward. In other words, the fire on the Hindenburg, for the most part, remained above the passengers and crew, who were confined to the gondolas and cabins in the lower part of the ship. Had they just kept their heads, they would probably have glided down to an albeit bumpy landing, yet suffering only bumps and bruises and a few burns.

God makes a similar declaration in Hosea 4:6: “My people are destroyed for lack of knowledge.” Of course, the context makes plain that He means Israel will undergo disaster after disaster because she rejects God’s knowledge, the truth about moral conduct and right relationships that produces a stable, prosperous, peaceful society. Yet the principle stretches to cover more than just spiritual knowledge. What we do not know about physics, biology, medicine, economics, politics, business, and so many other matters can land us in a heap of trouble.

Within this truth, however, is a paradox: We do not know what we do not know. How, then, can we avoid disaster due to our ignorance? There are two steps we can take to lessen our chances of being bitten by our lack of knowledge: 1) We can develop a habit of learning, of seeking knowledge, and 2) we can admit that we do not know everything. The first is an action and the second is an attitude, and they must be put into practice together.

One of mankind’s greatest fears is of the unknown. This is what makes death, darkness, and many other phobic things so terrifying; people have no idea what to expect from them, so they allow themselves to imagine bogeymen at every turn. Yet knowledge about these “unknown” matters can alleviate our fears and enable us to conduct ourselves with poise and confidence when they confront us. Thus, with the knowledge provided by God’s Word, death, though it remains a hated enemy, becomes, in Paul’s more comforting term, “sleep” (see I Corinthians 11:30; 15:51; Ephesians 5:14; I Thessalonians 4:14). Without this truth, as we witness in the actions of men ignorant of it, there is no telling what people will do with their lives.

Human beings do and say stupid things out of ignorance all the time, and it often comes back to bite them. A recent example from the news illustrates this point. Though Americans live in the most prosperous nation on the face of the earth, they are among the most ignorant when it comes to economics. Even the simplest workings of supply and demand seem to be beyond them, as we can see in the strident calls for price controls on gasoline and/or punitive regulations on oil companies for taking “exorbitant” profits during the recent run-up in gas prices.

A little knowledge of basic capitalism, however, puts what has happened over the past months into perspective. If either supply falls or demand rises, prices will naturally edge upward. In the present situation, supply has been reduced due to the destructive power of Hurricanes Katrina and Rita (among other factors), while demand has remained essentially constant (it has actually decreased slightly). Thus, when the supplies were tightest—right after the storms struck—prices rose, and now that new supplies are coming online, prices are falling back toward their previous levels, though it will take some time for that to occur completely, if ever. This is how a market economy works. If there were a glut of oil, or if demand fell precipitously, the gas price would plunge, and the oil companies would take a financial drubbing.

The most recent financial statements of oil companies belie the accepted wisdom concerning their “outrageous” profits: They are making about ten cents of profit per gallon of gasoline. In percentage terms, they make single-digit profits. In comparison, a profitable stock or well-managed mutual fund will garner 10-15% earnings for the investor over a year’s time. One could easily conclude that the oil companies are, in fact, bringing in only mediocre returns for their stockholders. (By the way, the government makes an average of forty-six cents on each gallon of gasoline in taxes.)

What happens if the government places price controls on gasoline? When this was tried in the 1970s, the price of gas actually doubled as supply shrank (nobody wanted to produce gasoline anymore, since there was no profit in it). Lines of cars waiting to fill up their tanks stretched down the road and around the corner. Despite their promise, price controls end up hurting both businesses and consumers.

What happens if the government punishes oil companies for windfall profits by raising their taxes? The same thing. If selling gasoline is not profitable for the oil companies, they will cut production, and the motorist will suffer higher prices and dwindling supplies.

This is Economics 101, but most Americans seem to know little about it. In their ignorance, they could listen to populist politicians who want to pass legislation instituting price controls and/or taxes on windfall profits—and end up worse off than before!

What we do not know—about the properties of hydrogen, the principles of capitalism, or some other matter—could destroy us. This is especially dangerous spiritually, which is why Peter urges us to “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (II Peter 3:18). Similarly, Jesus commands us to “seek first the Kingdom of God and His righteousness” (Matthew 6:33), and to ask, seek, and knock (Matthew 7:7-11). God promises to answer our requests with gifts that will help us unlock the shackles of ignorance, producing the confidence to live by faith even while the world falls to pieces around us.
