Biofuels

There are many reasons for wanting to wean ourselves off oil, but environmental issues and measuring out dwindling resources are two fairly significant ones. The trouble is, oil is incredibly convenient. It's energy dense and in cars, we can replenish it in minutes. So how do you take those...

We currently have two main issues in our transport future. The first is cutting down on fossil fuel use, ensuring our finite supplies can be used for longer than our current consumption levels would account for. The second is reducing greenhouse gas emissions, helping prevent runaway climate...

Since 2007, U.S. fuel producers have been required by law to include more and more ethanol and other biofuels in their blends. Now, Pike Research suggests, the biofuels mandate enacted as part of the 2007 U.S. Energy Act may be vulnerable to renewed political pressure. Pike notes that the drawbacks...

Air travel is currently the only realistic way of covering huge distances in very short spaces of time. Unfortunately, it's not a particularly green way of doing so either--airliners use large quantities of fossil fuels and emit plenty of pollutants as they whizz you to a far-flung destination...

For a century, we've gotten almost all our gasoline and diesel fuel from petrochemicals. Now Silicon Valley startup Solazyme [NSDQ:SZYM] is testing diesel fuel derived from refining renewable oils--produced by specialized algae--in two Volkswagen turbodiesel models. Since July 2012, the VW Passat...

Just because a car is old, or because it races, it doesn't mean it can't be green. Mercedes-Benz has been building diesel cars for what seems like an eternity--indeed, they were one of the first to produce a diesel production car. One such example is this 1959 Mercedes-Benz 190d that just sold on...

Whatever the merits of ethanol as a fuel or a gasoline additive--and it's taken some hits lately--it's still in the running. The same cannot be said, however, for cellulosic biofuels, those derived from advanced crops or waste products. On Friday, a Federal appeals court ruled that an EPA mandate...

The United Arab Emirates isn't known for its aversion to fossil fuels. The country has made its money from the stuff, and rapidly expanded in the last four decades into the vastly wealthy, oil-rich nation it is today. Yet as of December last year, McDonalds delivery trucks in the country have...

The U.S. Department of Energy (DoE) has announced it will put up another $10 million in funding towards the expansion of biofuels. It's the second positive announcement in recent weeks for biofuel advocates, as the Senate's "fiscal cliff" avoidance measures have also seen many biofuel initiatives...

It wasn't until 2 am yesterday morning that the U.S. Senate voted 89 to 8 to approve a bill to avert the "fiscal cliff" that took effect on New Year's Day. The House of Representatives then took an entire day of political wrangling before voting 257-167 to approve the Senate bill late yesterday...

Crude oil, from which all fossil fuels are made, is a dwindling resource. There will come a point, some time in the future, where the expense of extracting it from deep under the ground becomes too great for the return on investment. While one solution is to wean ourselves off fossil fuels...

Alternative fuels have recently suffered at the hands of the current Renewable Fuel Standard, a set of guidelines that dictate various aspects of alt fuels. Combined with droughts and political factors, the industry has had it tough recently--but renewable diesel is on track to change the...

Of all the Chevrolet models, the Corvette sports car may be the one least likely to be considered green. Indeed, the world rocked on its axis when the lead engineer said two years ago that, one day, there might be a Corvette Hybrid. But considerably sooner than that, you can have your very own...

Ethanol continues to be a political football, with the alcohol fuel coming under fire from the auto industry, environmental pressure groups, and others. The latest to line up against the corn-based fuel is a coalition of industrialized livestock and poultry producers that might collectively be...

Politics is never pretty, and the politics of alternative fuels seem even less so. Today, The Detroit News reports that the U.S. military's program to reduce its reliance on oil by using ethanol and other non-petroleum fuels could be de-funded in the military authorization bill that's now working...

NASA has developed a system that captures carbon dioxide and helps to prevent pollution from wastewater while creating renewable algae biofuel, fertilizer and possibly animal feed, too. NASA calls its system OMEGA, for Offshore Membrane Enclosures for Growing Algae, self-contained bags of...

Once upon a time, if you wanted to buy a used car, the place to start your search was the local used car dealer or newspaper listings. Over the past decade however, searching for a used car has become a lot easier thanks to Internet auction site eBay and its eBay Motors listings. Listing everything...

Sapphire Energy, a company that creates algae-based fuel, just announced a whopping $144 million in funding. In recent years several startups have emerged to create fuel out of plant material, all hoping to lure people away from gasoline made from crude oil. Solazyme, Algae.tec, and Sapphire Energy...

Progress comes slowly to the world of commercial shipping, but it is coming. Three years ago, we noted that one giant cargo ship emits as much as 50 million cars. Now, shipping lines are starting to experiment with biofuels, which offer several advantages: They contain no sulfur or so-called...

On the face of it, biofuels seem like an ideal short to medium-term solution for reducing our reliance on fossil fuels. After all, they could not only be grown at home--reducing dependence on foreign oil--but growing crops is also a renewable process, and net CO2 emissions are lower than burning...
