The Financial Times has leaked the results of the International Energy Agency's long-awaited study of the depletion profiles of the world's 400 largest oilfields, indicating that, "Without extra investment to raise production, the natural annual rate of output decline is 9.1 per cent." This is a stunning figure. Considering regular crude oil only, this means that 6.825 million barrels a day of new production capacity must come on line each year just to keep up with the aggregate natural decline rate in existing oilfields. That's a new Saudi Arabia every 18 months.

Richard Heinberg, Post Carbon Institute ... There is a veritable cottage industry of economists and statisticians (including Daniel Yergin, Bjorn Lomborg, Peter Huber, and Michael Lynch) who tirelessly implore their readers not to panic over oil prices because The Market will always come to the rescue. As easy conventional oil depletes, tar sands, oil shale, and biofuels become more economic to produce. Even coal-to-liquids becomes feasible on a large scale. And, as everyone knows, there is an endless amount of coal.

This is a guest post from Max Arturo Alcala Sainz. Currently, the list of academic institutions offering relevant and up-to-date information and courses geared to confront the imminent energy slope is awfully short. If you have ever tried to enroll in your local university for some hands-on Peak Oil learning experience, you may have found yourself disappointed in knowing that no such course is offered. Even in certain high-level economics courses that scrape at energy depletion and natural resources, you will probably be able to teach your professor a thing or two (if you are a keen reader of TOD). :)

Those of you who do not believe Peak Oil Theory should first make sure you fully understand it. According to this theory, after a reservoir has been depleted by half of its total volume, the output begins to plateau or remain constant for some unknown period. At some later time (which is unpredictable) the output begins a permanent decline of variable duration (which is also unpredictable) until the remaining quantity of oil is no longer economically feasible to extract with current technology. Therefore, Peak Oil Theory does not state that the earth is running out of oil per say. It states that the earth is running out of inexpensive oil, otherwise known as conventional oil - the high-grade oil that comes out by drilling on land and requires minimal refinement costs.

NEW ORLEANS - Researchers predict a "dead zone" of oxygen-depleted waters off the Louisiana and Texas coasts could grow this summer to 10,084 square miles - making it the largest such expanse on record.

In 2000 a Saudi oil geologist named Sadad I. Al Husseini made a startling discovery. Husseini, then head of exploration and production for the state-owned oil company, Saudi Aramco, had long been skeptical of the oil industry's upbeat forecasts for future production. Since the mid-1990s he had been studying data from the 250 or so major oil fields that produce most of the world's oil. He looked at how much crude remained in each one and how rapidly it was being depleted, then added all the new fields that oil companies hoped to bring on line in coming decades. When he tallied the numbers, Husseini says he realized that many oil experts "were either misreading the global reserves and oil-production data or obfuscating it."

Reliable, accessible and affordable energy has been one of the primary pillars of American prosperity since the dawning of the Industrial Age. Unfortunately, many of the energy sources that we have always used have been seriously depleted or produce a dangerous build up of waste products in our common environment. As the people's representatives, Congress wants to help change that pattern by enabling and encouraging entrepreneurs, established corporations and private investors to make the long term investments that will be required to change a pattern of energy use that has been developing for almost 200 years. One attempt at making that possible was the Energy Policy Act of 2005, which established a program where the federal government would back loans for carefully selected projects whose payback profile did not exactly match the demands of the short term thinkers on Wall Street. Unfortunately, that bill put the burden of developing the program onto the Department of Energy, an organization that remains ill equipped for the task. Part of the reason is that the DOE is dominated by other considerations (protection of the nuclear weapons stockpile) and by the established energy industry that has no desire or incentive to make a big change in the current market.

"Following the failure of the latest efforts to plug the gushing leak from BP's Deepwater Horizon oil well in the Gulf of Mexico, and amid warnings that oil could continue to flow for another two months or more, perhaps it's a good time to step back a moment mentally and look at the bigger picture-the context of our human history of resource extraction-to see how current events reveal deeper trends that will have even greater and longer-lasting significance. Much of what follows may seem obvious to some readers, pedantic to others. But very few people seem to have much of a grasp of the basic technological, economic, and environmental issues that arise as resource extraction proceeds, and as a society adapts to depletion of its resource base. So, at the risk of boring the daylights out of those already familiar with the history of extractive industries, here follows a spotlighting of relevant issues, with the events in the Gulf of Mexico ever-present in the wings and poised to take center stage as the subject of some later comments. Readers in the "already familiar" category can skip straight to part 5. "

China produces 95% of the worlds supply of the rare earth metal, dysprosium, a key metal in magnets used in the drive motors for hybrid electric vehicles - up to 100 grams of dysprosium per hybrid car produced, according to a Wikipedia reference. Dysprosium's magnetic properties also make it an important metal for wind turbines and electric vehicles. Could be vital for MagLev trains, too. Scarcity of the metal is a sustainability and a political issue, according to a recent article in the TimesOnline, Crunch looms for green technology as China tightens grip on rare-earth metals. This does not look good.
