Steering clear of the ethanol bandwagon
MICHAEL VAUGHAN

Nearly 40 new ethanol plants are expected to be built in the United States in the next year, which will push it past Brazil as the world's largest ethanol producer.

However, people like Jim Lemon argue that, for energy and environmental reasons, ethanol will never replace much gasoline.

The U.S. is using corn, among the more expensive crops to grow and harvest; Brazilian farmers produce ethanol from sugar at a cost roughly 30 per cent less.

The ethanol boom is taking place despite continuing doubts about whether the fuel provides a genuine energy savings, because large amounts of oil or natural gas go into making ethanol from corn, leaving its net contribution to reducing the use of fossil fuels in doubt.

And geographers like Lemon are concerned that large-scale diversion of agricultural resources to fuel could result in price increases for food for people, as well as the transformation of vast preserved areas into farmland.

Professor Lemon has had a long and distinguished career in the field of historical geography. He moved to the University of Toronto in 1967. Much of his work culminated in his book Toronto -- Since 1918: an Illustrated History (Lorimer, 1985), which was one of the finalists in the City of Toronto Book Awards of 1986.

His third and perhaps most important book is Liberal Dreams and Nature's Limits: Great Cities of North America since 1600 (Oxford University Press, 1996). It essentially argues that development is at an impasse at the end of the 20th century.

Vaughan: Lots of people are jumping on the ethanol bandwagon, but not you. You say there's no way ethanol can replace oil. Well, surely, ethanol can replace some of it. What's wrong with E10 (10-per-cent ethanol in gasoline) or even E85?

Lemon: Ethanol can replace some, yes. But how much? We don't know yet, but one can bet it will be a limited amount of liquid fuel -- maybe 10 per cent, hardly 85. Some sources are better than others -- sugar cane is better as Brazil has proven; corn is not good.

Vaughan: Let's talk specifically about grain-based ethanol, which usually means corn. You say this is a rip-off for the taxpayers.

Lemon: In the United States, the federal government grants 51 cents (U.S.) per gallon to producers.

Some say that subsidies aren't necessary, given the high price of oil and that corn-based ethanol can now compete, but the U.S. government is beholden to the farm belt.

The leading recipients are now not farmer co-ops, but the mega-agribusinesses Cargill and Archer Daniels Midland.

The basic problem with biofuels of all kinds, not least corn-based ethanol, is that the energy derived either exceeds the inputs or is only slightly positive.

Agronomist David Pimentel at Cornell has argued the former for years; U.S. Department of Agriculture researchers say ethanol delivers 1.3 times the energy expended. Even that net energy is very, very low.

Fundamentally, the reason gasoline and diesel from petroleum has been so cheap is that the net energy has been very high, especially from light sweet crude -- in the hundreds, if not thousands.

To be sure, synthetic crude from the Athabasca oil sands is estimated at only three-to-four-times inputs, though I have seen only a bare positive gain as well.

Why is oil great and corn poor? The power concentrated in a unit of oil is derived from millions of years of photosynthesis from ancient sunlight-fuelling plants. With corn, one is trying to make the same from one year's crop!

A survey in 2003 of U.S. demand points out that if the United States were to replace gasoline and diesel with biofuels of all kinds (crop waste and wood cellulose included) 3.5 times the current cropland and 1.9 to 2.5 forest land would be needed.

Food supplies would be seriously impacted -- driving up prices. Remember China and India are now importing food from the United States and other countries.

Vaughan: Is the net energy result any better with the cellulosic ethanol from straw, switchgrass or agricultural waste?

Lemon: Switchgrass is probably somewhat better than corn, but faces the same shortcoming. Assertions, such as I have read recently, that "it may be the answer to high pump prices and dependence on fossil fuels" are delusions. Maybe together with ethanol, cellulose-based could get us to 20 per cent. But think of the cost!

Vaughan: Is there any biomass that makes sense for ethanol production? What about waste streams?

Lemon: Certainly experiments are under way with cellulose. Sugar cane stalks and corn cobs can be used. But what about returning the waste of the fields and forests to the land to fertilize future crops?

Today, we are using synthetic fertilizers, from natural gas especially, to make nitrogen to boost farm outputs. Natural gas is becoming scarce like oil.

Often praised nowadays is Ottawa-based Iogen. I have heard that the firm touts its net energy at eight times. One should always be skeptical of company claims.

One can add that, for many years, burning waste has generated a small amount of electricity -- but only a small amount. And if our population were much, much smaller, we could heat with wood. But there are too many of us in Canada, let alone the United States and China.

Vaughan: Then what's your answer? Should we just keep using up the oil until it's gone and hope that hydrogen fuel cells are going to save the day eventually?

Lemon: Hydrogen will never be available in large amounts. The net energy liberating the gas from water through electrolysis is very likely negative. The only answer is to reduce or, to deploy the current jargon, the answer is "demand destruction." That is, we will be forced to shift our travel and shipping from motor vehicles especially.

China is mad -- as crazy as Mao's Great Leap Forward that denied the laws of physics and biology -- in shifting to the wrong direction. Now a net importer of oil and gas as well as agricultural products, China has even less forest and cropland to give over to biofuels than Canada or the United States.

Ditto India: It is also increasing its personal and freight movements by motor vehicles.

Coping with high oil prices
by Nikos Tsafos


The most surprising feature of the current oil crisis is that it does not really feel like a crisis. Oil and gas prices may be high and many people are struggling to cope with rising energy bills, but at a macro level, the world’s largest economies have grown consistently in the past two years. Hardly is our fear realized—that high energy costs will force an economic downturn, much less a recession. What explains this disconnect between expectation and reality?

To examine this question, take three mechanisms through which oil prices affect economic performance (there are more, but let’s focus on three): a reduction in income caused by the need to spend more money on energy leads to reduced demand for goods and services and this, in turn, forces an economic slowdown; an increase in inflation generated by higher prices that firms charge to cover energy costs leads to a reduction in real income; and worsening performance by firms, reflecting mainly higher costs and/or reduced overall demand by shrinking real income.

Begin with the first mechanism: US households spend more money on energy today—that much is obvious. But as Figure 1 shows, the amount spent on energy as a percentage of personal consumption is not very high, certainly not as high as it was in the late 1970s or early 1980s, when over 9% of personal consumption went to fuel oil, coal, electricity and gas. In 2005, energy expenditures as a share of consumption were 5.8%, up a full percentage point since 2003, but still below peak levels. Granted the data is not unambiguous—for example, current consumption is linked to high debt levels—but there is a clear sign that today’s high energy prices are not putting a strain on the economy that is comparable to that felt in the late 1970s.



What about inflation? Over the past fifteen years (1990-2005), there has been an observable decline in inflation, driven by a variety of factors unrelated to oil. As Figure 2 illustrates, the link between higher oil prices and inflation is all but clear (here is shown the Consumer Price Index excluding energy prices to gauge the effect of energy prices on other goods): in 1999-2001 there seem to be a rise in oil prices that is followed by an increase in inflation; after 2002, however, oil prices go higher, as inflation goes down; and by 2003, oil prices skyrocket, with only a minimal effect on inflation. Here, again, there are various exogenous factors to consider—mainly better macroeconomic management and the influx of goods from China, which have kept prices low. But this does not negate the underlying fact—that higher oil prices have not generated inflation, at least not to the level expected (and feared) by observers.



This reality produces the following question: could it be that firms are taking the hit? It is possible that firms would try to absorb energy costs in order to maintain demand for their goods. If this were true, we would expect firms that need a lot of energy to suffer more than firms that need less energy for their outputs. There is some evidence for this hypothesis, though the verdict is ultimately mixed: as Figure 3 shows, utilities and transportation—two energy intensive industries, had mixed results in 2004 with the former turning a profit while the latter suffering losses. From the rest (excluding Agriculture and Mining), there appears some trend, albeit weak, linking higher energy intensity and lower profits. At the same time, the numbers involved (energy costs at around 5-10% of total intermediate costs, and generally high profits) for most industries suggest that we cannot rely on this explanation—that firms are taking the hit—for understanding why oil prices are not having a large effect on the economy.



Perhaps the clearest view on this question comes from a more basic statistic: how much do firms spend on energy? Figure 4 shows gross output in the United States for the years 2000-2004 (gross output is labor and capital expenses, which make up GDP, as well as firm expenditures on energy, materials and services). The left axis plots gross output while the right axis shows total energy costs. What is impressive is that energy costs make up such a small portion of total costs (or total output). Even with high prices in 2004, energy costs make up about $450bn or 4.5% of total input costs. More than anything else, this should underscore why large changes in energy expenditures are not placing as high a strain on the economy, even though the fact that prices have risen more orderly than in the past may help explain why the adjustment has been less painful.



Granted, economic performance is but one aspect of the current energy crisis; it may not even be the most important. Granted too, that these numbers rest on a macro-level analysis and may conceal many problems, not least that of that families trying to pay their energy bills. Granted also that there are many international dimensions (even imbalances) to consider that may be salvaging economies from recession. But there is still some truth in here—that economies can grow in spite of high energy prices should make us rethink energy security and the calamities we tend to associate with rising oil costs. It may also give us some reassurance about our ability to make the transition from hydrocarbons to other energy sources as painless as possible. And that is good news for the long term.

~~~~~~~~~~~~~~~ Editorial Notes ~~~~~~~~~~~~~~~~~~~

Andrew McKillop deserves some recognition for predicting early on that high oil prices will drive economic growth – up to a point. Here's some excerpts from some of McKillop's articles published on Energy Bulletin:

Increasing oil and gas prices, up to levels around $75/bbl or barrel-equivalent ($10-13/million BTU) will certainly be called ‘extreme’, but will not in fact choke off world energy demand.

The likely net impact of price rises to $75/bbl, if interest rates in the OECD countries are not ‘vigorously’ increased to double-digit base rates, will be increased world oil demand due to continued and strong economic growth. This ‘perverse’ impact of higher prices will therefore tend to reduce the time available for negotiating and planning energy and economic transition.

Only at genuinely ‘extreme’ oil prices, well above US$100-per-barrel, will the pro-growth impact of increasing real resource prices be aborted by inflationary and recessionary impacts on the world economy.

This will come too late to offer any chances of organized and efficient economic and energy restructuring, especially in the OECD economies and societies, which are the most oil-dependent due to their high or extreme average per capita rates of oil demand.
( 22 September 2004) and
Higher oil prices increase world economic growth by raising ‘real resource’ prices, through what we can call ‘the revenue effect.’ The pro-growth impact of oil does not stop there, because fast increasing values of world merchandise trade due to higher ‘real resource’ prices directly leads to fast growth of world liquidity ... the quantity of money in circulation. The trend for world liquidity is close-linked to oil price changes (both up and down), but in the current context there is also growing world liquidity due to fast industrialization of, and growth of exports from China, India and other countries. This directly translates to additional growth of the value and volume of world trade. World trade is now growing at its fastest rate for over 15 years, which again is concrete, cast iron proof of fast economic growth.
