The summer E15 waiver could save Americans $10 billion nationwide, says Growth Energy

Biofuel groups are laying out the numbers, showing the potential for big savings this summer with E15.

Growth Energy CEO Emily Skor says Americans stand to save more than $10 billion this summer. It follows an emergency waiver issued earlier this year, which allowed sales to continue throughout the summer.

In Iowa, the group estimates drivers could save up to $140 million on fuel costs this summer. In Illinois, those estimates jumped to more than $400 million in savings.

Despite the good numbers, Skor says it is time for Congress to pass permanent legislation, allowing unrestricted access to E15.
