The first half of 2015 had low gasoline prices due to low crude oil prices.
In 2014, corn prices averaged $3.30 per bushel.
In 2012, farmers endured a drought which pushed up corn prices to near or above $8 per bushel (record high).
In the fall of 2009, expectations for a record corn harvest came to fruition. Corn and ethanol
prices felt the impact and were pushed lower. Even with the expectations and then the actual harvest
record, annual consumption of motor gasoline for 2009 totaled 261,179,445 gallons, which was an
18–percent increase from 2008.
In 2008, increases in gasoline prices worked as an incentive for consumers to use an
ethanol–blended fuel. Gasoline prices began to fall, but motorists did not immediately
return to using 100–percent gasoline. The annual consumption for 2008 totaled 221,355,779
gallons, which was a 22–percent decrease from 2007.
Total gasoline consumption for 2007 was 285,501,195 gallons, which was a 24–percent decrease
from 2006. Additional ethanol operating capacity had pushed ethanol prices lower, and gasoline
prices had finally reached the level that people would no longer pay. Since 2001, total consumption
had fallen over 50 percent.
Consumption increased from January to March of 2006 paralleling a reduction in ethanol–blended
fuel consumption possibly due to the increase in the price of ethanol.
Consumption numbers for April through November were contradicted by similar but opposite movements
in ethanol–blended fuel consumption.
Gasoline consumption decreased significantly in 2005 from prior years. Increased availability
and increased consumption of ethanol–blended fuel were likely factors in
these reductions. Total consumption of gasoline and ethanol–blended fuel
changed very little from 2000 to 2004 which indicates a shift in consumption of the individual
fuels. The ethanol–blend market share is also a sign that there is an increase
in ethanol–blend substitution for gasoline.
