E10

The minimum requirements for ethanol levels in the US are getting more difficult to reach because cars today getting better fuel economy.

For 2017, EPA calls for 18.11 billion gallons of biofuel to be mixed in gasoline and diesel. But it shouldn't affect you at the pump.

A proposal from the Obama administration would lower the 2014 Renewable Fuels Standard level to the amount actually used last year, and goes up from there.

California, Pennsylvania senators reach across the aisle to propose an anti-corn-ethanol bill.

Members of the Oregon House of Representatives are proposing a bill to repeal the state's mandate to use a 10-percent ethanol mix in gasoline.

The Environmental Protection Agency (EPA) is not going to decide just yet how much biofuel to add to the national fuel supply in the future. Last year, the EPA said, for the first time ever, that it might reduce the biofuel component in American gas, but is now saying that the 2014 standards rule will be "significantly delayed."

Green transportation issues were not at the top of this year's midterm elections in the US, but the sweeping Republican victories – and probably new Senate Majority leader Mitch McConnell – could affect at least some aspects of how we get around without using as many resources as we used to.

The fight over converting the national supply of gasoline from a maximum 10-percent ethanol blend (known as E10) to E15 have quieted down somewhat when it comes to passenger cars. For other applications - like "motorcycles and nonroad products" - the stru

Some of the largest retailers in the US are trying to inject either a little good sense or paranoia into part of their customer base. Lowe's, Walmart and True Value are putting out written warnings about the dangers of filling up non-light-duty-vehicle engines with fuel that contains a higher ethanol blend. It's all part of a campaign backed by the Outdoor Power Equipment Institute (OPEI), which represents 100 small-engine, utility vehicle and outdoor power equipment makers.

In late 2013, the US Environmental Protection Agency (EPA) proposed – for the first time ever – a slight slacking of the 2014 renewable fuel standard. The reason was that the US is coming up on the 'blend wall,' the overall level of ethanol in the national gasoline supply where adding any more biofuel would p

Many automakers are already and quietly ready for E15.

In the simplest terms, when higher-ethanol blend fuels spill, they can make buildings go boom. And the study that says this was funded, in part, by Chevron and Shell as well as the American Petroleum Institute, while the report was generated by Rice University in Houston. All clear on the players? Good. Let's proceed.

A public meeting room was packed recently as the US Environmental Protection listened to comments about its recent Renewable Fuel Standard (RFS) decision. About 300 people packed the room, and the two sides were clearly marked. Some people were biofuel producers or Iowa farmers wearing "Don't Mess with RFS" buttons; others wore "Save my Engine" t-shirts handed out by Energy Citizens, a group funde

Forget raising the national ethanol blend in standard gasoline to 15 percent (E15), the Environmental Protection Agency has, for the first time ever, proposed reducing the ethanol requirement in the American gas supply.

AAA is continuing its assault against higher ethanol use in the transportation energy, speaking out in support of reducing the renewable fuel mandate for 2014. The organization said that renewable-fuel requirements need to be lowered to avoid the so-called "blend wall" that could drive up gas prices. In addition to the threat of such higher prices, AAA continued to call gasoline with a 15 percent ethanol blend, or Danny King

A 50-percent increase in alcohol content may knock even the most seasoned drinker off of his (or her) feet, but a 50-percent jump in ethanol won't throw off a car's engine. That's the short version of a new National Renewable Energy Laboratory (NREL) report, and we expect pro-ethanol advocates to use it frequently against Danny King

The Renewable Fuels Association (RFA) is giving us up to 2.6 trillion reasons why blending ethanol with the US fuel supply are a good thing for the economy. Citing former Ford and Carter administration energy advisor Philip Verleger, the RFA estimates that gas would be between 50 cents and $1.50 more per gallon than its costs today. That means that Americans are saving $700 million a year on the low end and $2.6 trillion on the high end.
