Previous Years
The first half of 2015 had low gasoline prices due to low crude oil prices. As the year progressed, gasoline prices sunk even lower as the prices followed the crude oil prices.
In 2014, corn prices averaged $3.30 per bushel.
In September of 2013, suppliers replaced 87 octane regular unleaded gasoline with 84 octane regular
unleaded gasoline. Regular unleaded gasoline was blended with premium gasoline or ethanol to increase
the octane from 84 to 87.
In 2012, farmers endured a drought which pushed up corn prices to near or above $8 per bushel (record high). Ethanol prices were lower due to high ethanol inventories, and by the end of 2012, ethanol
demand was very strong. Gasoline demand dropped 6 percent in 2012 as more drivers filled up with
ethanol–blended fuels.
In the spring of 2010, Nebraska was experiencing high corn prices and low petroleum costs.
The year 2009 brought a record harvest corn crop, the news of which pushed corn prices down. Since
corn is the top raw material cost for distillers, lower corn prices increased ethanol margins. While the
ethanol industry saw shutdowns, bankruptcy filings and curtailments since late 2008, larger ethanol
margins were welcome. U.S. ethanol production for 2009 was also expected to be higher than 2008 due to
biofuel blending mandates calling for annual increases in corn ethanol. The ethanol average was $1.79 in 2009
compared to $2.47 in 2008 (a 28–percent decrease), and the unleaded gasoline average was $1.76 compared to
$2.57 (a 32–percent decrease). Unleaded gasoline's average broke an upwards trend that started in 2002.
Ethanol's average was at a level not seen since 2005.
The year 2008 brought crude oil prices to a peak soaring above $140 in July. Likewise, unleaded gasoline
prices were volatile, reaching over $3, and then falling close to a dollar. The ethanol average was $2.47 in
2008 compared to $2.24 (a ten–percent increase) in 2007, and the unleaded gasoline average was $2.57
compared to $2.23 (a 15–percent increase). Unleaded gasoline's average fell in line with a trend that started
in 2002. Ethanol's average was higher than 2007's average but still short of 2006's average.
The year 2007 brought additional operating capacity for ethanol and, with the additional supply,
brought lower prices. Higher crude oil prices pushed unleaded gasoline prices higher. The average ethanol
price for 2007 was lower than 2006, but the 2007 average unleaded gasoline price was higher than 2006.
The ethanol average was $2.24 compared to $2.58 (a 13–percent decrease), and the unleaded gasoline average
was $2.23 compared to $1.94 (a 15–percent increase).
The year 2006 brought the MTBE phaseout and the switch to ethanol as an additive. The average prices for
2006 for both ethanol and unleaded gasoline were higher than the average prices for 2005. The ethanol average
was $2.58 compared to $1.80 (a 43–percent increase), and the unleaded gasoline average was $1.94 compared to
$1.66 (a 17–percent increase).
