Since 2007, the Renewable Fuel Standard has required increasing levels of ethanol in gasoline blends sold in the U.S. Most fuel stations across the United States no longer offer pure gasoline, with E10—a blend of 10 percent ethanol and 90 percent gasoline—prevailing. After years of debate, the EPA has now announced it will study the... EPA to study cutting amount of ethanol in U.S. gasoline

For almost a century, many people have blamed oil magnate John D. Rockefeller for the demise of ethanol as a viable fuel for internal-combustion engines. He fought its use, the theory goes, to eliminate competition for the gasoline derived from his Standard Oil business—whose descendant companies still extract and sell fossil fuels today... 
While political control in Washington has changed, the debate over a mandate to blend specific volumes of ethanol into the U.S. fuel supply has not. Since its passage in 2007 as part of the Energy Independence and Security Act, the ethanol-mandating Renewable Fuel Standard has attracted controversy. Its requirement of specific volumes of ethanol... 
The confirmation of Scott Pruitt as Environmental Protection Agency administrator was expected to rankle environmental groups. Pruitt is a climate-science denier who, in his previous position as Oklahoma attorney general, sued the agency he is now charged with many multiple times over its efforts to enforce environmental regulations. But what may... 
Efforts by the U.S. Congress to cap the amount of ethanol blended with the U.S. fuel supply appear to be gaining momentum. The current Renewable Fuel Standard, passed as part of the 2007 Energy Independence and Security Act, has proven increasingly unpopular among certain legislators. But ardent support from the renewable-fuels industry and the... 
At least in North America, ethanol is a contentious fuel. A decade ago, it was seen as a homegrown and carbon-neutral way to use less gasoline—and federal legislation mandated that increasing volumes be blended into U.S. fuel supplies. Much debate followed over using "food for fuel," its supposed carbon neutrality and the footprint of the...
