ATLANTA - A recent spike in the price of ethanol mixed into Georgia's gasoline supply is getting some blame for a 20 cent increase at the pump.
However, a leading energy expert from Georgia Tech told Channel 2's Jim Strickland the recent price increase on gas goes beyond ethanol.
"It's a seasonal spike," said researcher Sam Shelton. "The price of gasoline always goes up in the spring, because they're switching over to a new blend to reduce the emissions in the summer."
Refining the less-polluting summer gas required in Georgia costs more.
Shelton says a short-term spike in the price of ethanol due to a logistical shortage of rail cars to transport corn had only a marginal effect on prices here.
"Your gas didn't go up because of ethanol prices.
, and that was a small element, but not the dominant element," he said ,. "The predictions are they'll hit probably $3.70 or so, but you've got to remember we've had gas prices over $4, so everything's relative."
