A popular conception of biofuels

Biofuels: A bit of chemistry Biofuels, like ethanol and biodiesel, are designed fuels derived from biological carbon fixation. Ethanol is produced from the fermentation of carbohydrates produced by the sugar found in plants like corn and sugarcane. Ethanol can be used as an alternative car fuel, like the E85 used in Brazil, or as a gasoline supplement, like the E10, which is common in North America. Ethanol by-products, dry and wet distillers grains, are fed to livestock. The ratio of energy produced by sugar cane-based ethanol over the energy needed to produce it varies between 8.3 and For corn-based ethanol, the ratio varies between 1.3 and 1.6.

Biofuels: a bit of history  Ethanol has been with us for a surprisingly long time. The Ford model T could run on gasoline or ethanol and Henry Ford was reportedly an ethanol advocate.  The first use of sugarcane ethanol as a fuel in Brazil goes back to the 1920s. A 50% mandatory blend was imposed in 1943 as a response to threatened oil supplies during WWII.  Until the early 1970s, oil was cheap and ethanol was not competitive. Environmental issues were not in public policy discussions.

The events that changed the views on ethanol The two oil shocks (1973 and 1979) made oil importing countries aware of the dangers of oil dependancy and willing to subsidize the production of alternative fuels. Brazil embarked on its « Programa nacional do alcool » in 1975 and a blending mandate varying between 10% and 22% was used between 1976 and Cars running on E100/neat ethanol were first commercialized in Brazil in Brazil imposed a mandatory blend of 22% anhydrous ethanol in The mandated blend has varied between 20% and 25% afterward. First Flex Fuel cars sold in 2003.

Brazilian ethanol: a case illustrating the infant industry argument?  Price subsidies for ethanol producers  Low interest loans to encourage investment  Subsidized ethanol retail prices below gas prices  Private and public investments in R&D  By 2004, technological advances and economies of scale made ethanol competitive with gasoline (Goldemberg, 2008).  In 2007, Brazil exported about 20% of its production, but it has been importing from the United States recently.

Recent changes in the United States  The US$0.54/gallon tax on ethanol imports and the US$0.45/gallon tax credit on blending have been terminated at the very end of 2011, saving an estimated US$6 billion/year to US taxpayers (Babcock, Barr and Carriquiry, 2010).  The 2005 Energy Policy Act required that 7.5 billion gallons of renewable fuel be used by  The 2007 Energy Independence and Security Act imposed an annual limit of 36 billion gallons for 2022, of which 44% must be advanced renewable fuel.  Ethanol as a fraction of gasoline use went from 1% in 2000 to a bit less than 10% in  Production is concentrated in the Midwest (Iowa, Nebraska, Minnesota, Illinois and Indiana).  As recently as 2009, the US was a net importer of ethanol, but it exported 940 million gallons more than it imported in 2011, from an estimated production of million gallons.

Ethanol production in Canada  Canada produced 462 million gallons of ethanol in  This makes it the fifth largest producing nation in the world, behind the US, Brazil, the EU and China.  As of December 2010, Canada mandated that ethanol account for 5% of gasoline use.  Grier, Mussell and Rajcan (2012) evaluate government support at $250 million/year.  Some provinces, like Quebec, have decided NOT to expand their production capacity of corn-based ethanol, but invested $27 million to help Enerkem and Greenfield Ethanol build a full-scale commercial cellulosic ethanol plant.

The economics of mandates What if the mandate is increased? What if the price of corn increases?

Biodiesel: production trends

Biodiesel in Canada and elsewhere  In Canada, renewable fuel regulations mandate that biodiesel be blended to represent 2% of all diesel fuel sold, or over 1.5 billion litres of biodiesel.  Current production and production capacity are low, but Alberta, Ontario and Quebec have projects for larger plants.  Mixes of biodiesel and petrodiesel commonly marketed include B100 (100% biodiesel), B20 (20% biodiesel, 80% petrodiesel), B5 and B2. The last three can be used in standard diesel engines.  In France, buses equipped with special engines run on a 50% blend.

Land diversion: US Corn acreage over time

Corn acreage in Canada ( )

Consequences of ethanol boom  US corn demand for ethanol is up, but exports and feed use are down.  Rising feedgrain prices in the United States and Canada made livestock producers angry at ethnanol policies, but made land owners happy. The average price for an acre of cropland in the US was around $1600 in 2003 compared to $3200 in 2011.

Corn and oil prices

Is ethanol responsible for the high and volatile price of corn?  Mitchell (2008) said « yes ».  OECD (2008) said « some »  Baffes and Haniotis (2010) said “not really”  Effect on food prices differ between poor and rich countries. Many causes: - Strong aggregate demand stemming from economic growth in the developping world, low inventories and inelastic supply and demand functions; - Weather and other exogenous shocks; - Peculiar policies (Tangermann, 2011); - Speculators; - Commodity prices are not more volatile than before.

Is the price of corn more « exposed » to oil price shocks than before?  The relationship between corn and oil prices has evolved over time.  3 structural breaks: 2 nd oil price shock, end of export subsidy war between the US and the EU and the ethanol boom.  The corn price systematically adjusts to oil price shocks in recent years only. The converse is not true: the oil price does not systematically adjust to shocks to the price of corn (El Marzougui and Larue, 2012).

Conclusion  Biofuels are a response to concerns about dependency on foreign fossil fuels, a desire to curb GHG emissions and a desire to redistribute wealth with a specific regional/commodity focus.  A more efficient way to internalize the environmental externality would be to tax sources of GHG emissions.  Canada’s mandates on ethanol and biodiesel are relatively low and hence not too distorting.  Ag prices are more than ever affected by oil price shocks.  Arable land endowments are trending downward in many parts of the world, pressure to get better yields (more bushels/acre, more ethanol per bushel).  How will demand for fuels and food change in the future?
