Few topics get our commenters more riled up than ethanol. Both sides weigh in with fervor and passion, debating energy security versus agricultural policies and costs, comparing studies on wells-to-wheels carbon dioxide profile versus the impact on older engines, and more. But marine users in...

Anew bill would discard a mandate requiring larger volumes of ethanol be added to the U.S. fuel supply.

Large-scale biofuel production requires cutting down forests, but will that do more harm than good?

Cars running on natural gas have been around for decades now, and presently represent 2 to 3 percent of global auto production. Their tailpipe emissions are much cleaner than gasoline or diesel cars. And North American production of natural gas has soared over the last decade. You might think that...

It's the end of another Congressional session, which means that a budget extension bill has now been rushed through and is likely to be signed. Called The Tax Increase Prevention Act of 2014 (H.R. 5771), it contains special provisions, rule tweaks, and concessions for many, many, many different...

South African tobacco farmers could grow jet fuel in the near future.

Natural gas is very much in the public consciousness right now, if not for all the best reasons. Seen as a cleaner, more energy-independent fuel than fossil fuel oil, it nevertheless has its detractors, largely concerning the 'fracking' process through which it is extracted from the ground. But its...

How do you ensure that all fuels are treated equally, and that customers are aware of the benefits and drawbacks to every alternative to gasoline power? One of the most effective ways is to compare a new fuel to one consumers are already familiar with. That's why a group of natural gas advocates...

In an action sure to appease fans of a greener transportation future, the U.S. Supreme Court has chosen to decline oil and ethanol companies' appeal to a decision to uphold California's Low Carbon Fuels Standard (LCFS). That means the LCFS now has one fewer obstacle in its aim to encourage the...
