  • 6 Recoverable Resource Depends on Price Energy-Reserve Revisions, Dec 16th, 2008, by John Donovan THE WALL STREET JOURNAL John Donovan Falling Oil, Natural-Gas Prices Render Certain Proved Stockpiles as Uneconomic Many companies will likely be forced to declare that big chunks of their oil and gas reserves are uneconomic. That could have wide-ranging implications for oil companies, which need to show increasing reserves to attract investors and, in some cases, to serve as collateral on loans. Oil and gas producers must report annually the size of their proved reserves that is, how much oil and gas they believe they can produce from the fields they control. Under securities rules, they can include only oil that can be produced economically a calculation based on oil and gas prices at the end of their year, usually Dec. 31.

  • 15 In the News NY Times Lithium: February 3, 2009 In Bolivia, Untapped Bounty Meets Nationalism By SIMON ROMEROSIMON ROMERO UYUNI, BOLIVIA In the rush to build the next generation of hybrid or electric cars, a sobering fact confronts both automakers and governments seeking to lower their reliance on foreign oil: almost half of the worlds lithium, the mineral needed to power the vehicles, is found here in Bolivia a country that may not be willing to surrender it so easily. Japanese and European companies are busily trying to strike deals to tap the resource, but a nationalist sentiment about the lithium is building quickly in the government of President Evo Morales, an ardent critic of the United States who has already nationalized Bolivias oil and natural gas industries.

  • 19 Example of energy lost during conversion and transmission. Imagine that the coal needed to illuminate an incandescent light bulb contains 100 units of energy when it enters the power plant. Only two units of energy eventually light the bulb. The remaining 98 units are lost along the way, primarily as heat. Overall Efficiency of an Incandescent Bulb 2% Lighting accounts for 22% of all electricity usage in the U.S. No energy loss value assigned to getting the coal from the ground to the power plant (mining, transportation, etc) Waste heat

  • 29 Conclusions: Key Science Education Questions What do we want our students to know ? Why do we want them to know it ? General Education vs Science Majors How do we provide context? Do we provide maximum information and hope some sticks? or Do we provide the bare bones and demand it all sticks? Undergraduate level objectives ? Graduate level objectives? Career level objectives?
