On the weekends, I get the paper version of the New York Times, so I actually see articles that aren't on the front page. Today's edition is chock full o' revelant articles.

The business section is starting a week-long series called "Beyond Gasoline" that examines alternative technologies for powering cars. The first article is about ethanol.

Right next to it is a column that seems to be a follow-up to the NYT Magazine story about peak oil from a few weeks ago. It features quotes from the usual suspects—Pickens, Simmons, Yergin, Lynch.

Over in the front section, there is a lighter story about the quandary faced by gas stations where the pumps have mechanical dials that only go up to $2.99/gallon.

Finally, there is more on the Amtrak fare hikes in the Northeast corridor. The reason: high diesel costs. I can't find a source for this, but I think that the Northeast corridor is electrified, meaning that the price increases on Amtrak's only profitable line are subsidizing diesel costs incurred by the rest of the system.
