Iranian Nuclear Deal Clears The Way For $2 A Gallon Gas - Was It Worth It?

If approved, the historic nuclear deal with Iran could be a boon for U.S. consumers and a bust for environmentalists.

The deal, which would place strict limitations on Iran's nuclear program in exchange for relief from economic sanctions, must now get the green light from U.S. Congress. But as Iran, the country with the world's fourth-largest oil reserves and second-biggest gas fields, revs up its output, analysts expect the cheap prices that defined 2015 to extend "well into 2016."

"This is good news for consumers, and bad news for people trying to promote non-fossil fuel alternatives or renewables," Tom Kloza, global head of energy analysis at the Oil Price Information Service, told The Huffington Post on Tuesday. "It means fossil fuels will remain cheap, and that inhibits some efforts to reduce carbon."
