The pros and cons of White House proposal of E15 gas
(KYMA, KECY/ CNN) - The latest White House idea to reduce gas prices involves an emergency waiver from the Environmental Protection Agency.
It allows year-round sales of 15% ethanol blend gasoline.
Ethanol comes from plants like corn, so its biggest advantage is price. Experts say E15 gas could be up to ten cents a gallon cheaper than regular fuel right now, but the EPA has a reason for capping ethanol content at 10% during the summer.
That's because it creates more smog than normal gas because it evaporates faster and reacts with sunlight, and summer weather can make that worse.
Ozone smog isn't just an environmental problem -- it's also a health concern.
Some Republicans say broader action is needed to really lower gas prices.
