Biofuel

So far, Ted Cruz has been spared Donald Trump's attacks against his Republican opponents. Now, the gloves are off on the topic of ethanol.

The EPA is boosting the amount renewable fuels in the US gasoline supply despite opposition by an unusual alliance.

USDA announces plan to nearly double the number of biofuel pumps across the country with $100 million in grants to match state-level and private funding.

With a potential 7.3 billion annual passengers, the aviation industry is looking to biofuels as the only path to greener airplanes.

Drivers in Auckland, New Zealand were able to fill up their tanks with a biofuel called 'Brewtroleum', a fuel distilled from the grain and yeast leftover from the beer making process.

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.

A study by Lux Research figures that China can reduce its gasoline usage by up to 483 billion gallons by maximizing its foray into alternative fuels.

Two biofuel producers – AFI and AFPM – filed a lawsuit earlier this year to get the EPA to make a decision about the 2014 RFS. Today, the EPA said it will decide by the end of November, 2015.

A train carrying ethanol crashed three weeks ago and spilled 55,000 gallons into the Mississippi river. The long-term effects are unknown.

The European Parliament's Environment Committee votes to put a cap on first-generation biofuel use by 2020.

The US sold 836 million gallons worth $2.1 billion of ethanol abroad, and Canada was the largest importer.

The federal government mandates that a certain amount of ethanol be blended with gasoline. The price of corn-based ethanol hasn't been affected by the same anchor-drop in price as petroleum fuel, however, and along with that, the complicated mechanics of its pricing and trade are said to be what is keeping the price of gas from falling even further.

When sewage is treated at a wastewater treatment facility, biosolids are the byproduct. After being separated from the water, biosolids are usually sent to a landfill or incinerated. That doesn't mean that they're without value, however. Vitruvian Energy has created a process to make a usable fuel out of this human waste product, and while the source is pretty gross, it is undeniably abundant, and the results are much cleaner.

Here's a blast from the past, the name BioWillie hasn't been heard on these pages since 2008, and its reappearance today isn't a bit of good news. The ambitious plan from country music singer WIllie Nelson to help American farmers by turning their crops into American fuel for American truckers (are you noticing a theme?) has officially Sebastian Blanco

November's coming up, so that must mean some election-season lobbying is on the way. One of the subjects being debated in the US right now is the how much renewable fuel must be included in the US gas supply. And advocates are already taking to the digital airwaves to make their point.

Rapping and bragging about cars goes back practically to the very beginning of the genre. After all, a lot of hip-hop is about presenting a tough swagger and having a cool ride is a huge part of that. The group The Mighty 190 certainly isn't the first to rap about rolling in a Mercedes-Benz, but it might be the only one to rhyme about cursing in a vegetable-fueled Mercedes 190D.

if you've ever felt like going to the gas station was in some ways similar to a junkie visiting a dealer, we've got the movie for you. Pump: The Movie is coming to theaters next month and it looks like it's going to put the addiction to oil message front and center. We like the movie's take-no-prisoners tagline: "Some battles need bullets. This one needs tanks."

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellu

For many of us, coffee runs our lives. Without the bitter, caffeinated brew, most of us wouldn't be able to get up in the morning or avoid fading in the afternoon. Now, new research from the University of Bath suggests we might want to get our cars as hooked on java as we are. Regardless of the variety of coffee used, the UK institution has found that coffee grounds are a great source to create biodiesel.

Arguing over the pros and cons of using ethanol as a transportation fuel isn't just an American thing. The Brazilians are going at it, too. We will translate.
