As the earth warms and our hunger for oil and other natural resources grows, the Arctic—once a peaceful repose for Santa—is already a crisscross of territorial claims that could get even more complicated in coming years according to a new map drawn up by researchers at Durham University, who say it is the only geographically accurate map of its kind.

Your car is going to drive you to work someday. Until then, car makers are experimenting with ideas that take control away from you in subtle, helpful ways – mostly to help increase fuel efficiency.

A new study by the University of Alberta suggests that a massive undersea volcano eruption 93 million years ago was the source of much of the world’s oil.

Researchers Steven Turgeon and Robert Creaser were alerted to the prehistoric blast when they found specific levels of osmium isotopes (indicators of volcanic activity in sea water) in black shale rocks off the coast of South America and in the mountains of central Italy.

As California returns to requiring automakers to sell zero-emissions vehicles, BMW is apparently aiming to get in first on the gold rush. Automotive News reports BMW will export an electric version of its Mini to California. The state's zero-emissions vehicle program will require nearly 60,000 plug-in cars to be sold in the state between 2012 and 2014.

For those looking to get themselves off the grid—or at least move toward that ideal—a number of options are currently available. You can tack solar panels onto the roof of your house. You can erect a small wind turbine in your yard. You can now even distill ethanol in your garage. The EFuel 100 MicroFueler is a device the size of two very large refrigerators which will convert 490 pounds of feedstock (sugar and yeast) into 35 gallons of ethanol over the course of a week. Plug it in to any standard outlet and it will consume 150 watts for each batch. But while the concept of manufacturing your own fuel sounds appealing on its face, I'm not entirely sure the numbers add up to make it worth it.

Money doesnt grow on trees, so it should stand to reason that diesel fuel wouldnt grow on trees either. And yet the Brazilian Copaifera langsdorfii tree has been quietly producing a natural diesel variant in the tropical rainforest, something weve known about since the seventeenth century. Its only now that farmers in Australia have decided to farm the tree on a large scale in the hopes of having 20,000 living, above-ground fuel wells.

With oil prices recently breaking the psychologically important barrier of $100 per barrel, commuters aren't the only ones feeling the heat. Cargo vessels are responsible for moving 98% of all intercontinental goods, and a transatlantic crossing on fully-loaded 200-meter ship is not light on the diesel consumption. So far, at least two companies promise to deliver a technology not seen on massive ocean-going ships in quite some time: the sail.

"Cellulosic ethanol technology is a lot closer to reality than a lot of articles would have you think," said Jacques Beaudry-Losique, manager of the Department of Energy's Biomass Program this morning at the American Association for the Advancement of Science meeting. After some well-publicized studies stated that corn-based biofuels might exacerbate CO2 damage to the environment, focus has shifted to these so-called "second generation" biofuels that use non-food crops such as switchgrass, wood chips or crop residues (e.g. all the parts of the corn plant that are currently wasted after harvest--the stalk, leaves and "cob").

Over the past several decades, the promise of the "car of tomorrow" has remained unfulfilled, while the problems it was supposed to solve have only intensified. The average price of a gallon of gas is higher than at any time since the early 1980s. The Middle East seems more volatile than ever. And even climate skeptics are starting to admit that the carbon we´re pumping into the atmosphere might have disastrous consequences. To these circumstances, automakers have responded with a fleet of cars that averages 21 miles per gallon, about four miles per gallon worse than the Model T.

With all the buzz about hybrids, it´s easy to ignore our homegrown alternative fuel: ethanol. Clean-burning and infinitely renewable-we´re talking grain alcohol-ethanol is dear to environmentalists and economists alike. The standard 85/15-percent ethanol/gasoline blend (E85) is widely used in Sweden, but there are only 313 E85 fueling stations in the U.S.
