Net energy -- a useless, misleading and dangerous metric, says expert

As oil becomes scarce, the world needs new transportation fuels. As new fuel options develop we need means of assessing which are most effective at replacing petroleum. So far many scientists have used a measure called "net energy." However, Professor Bruce Dale from Michigan State University claims, "Net energy analysis is simple and has great intuitive appeal, but it is also dead wrong and dangerously misleading -- net energy must be eliminated from our discourse."

1. Metabolic syndrome -- don't blame the belly fat
   07-16-2007 · EurekAlert!
   Abdominal fat, the spare tire that many of us carry, has long been implicated as a primary suspect in causing the metabolic syndrome, a cluster of conditions that includes the most dangerous heart attack risk factors: prediabetes, diabetes, high blood pressure, and changes in cholesterol. But researchers have found that insulin resistance in skeletal muscle leads to alterations in energy storage that set the stage for the metabolic syndrome.

   03-13-2007 · EurekAlert!
   In the debate over alternative energy resources, geothermal technology has received scant media attention. Advocates call it one of the cleanest, sustainable energy resources available. However, steep construction, equipment and drilling costs have prevented more widespread development of geothermal technology. An Ohio University hydrothermal systems expert is working to change that.

    "Will the proposed National Renewable Portfolio raise or lower average electricity prices?" "Will a national standard prevent price gouging and "gaming" between states?" "Can electric utilities save money by supporting a national renewable energy policy?" The Network for New Energy Choices addresses these and many other questions in "Renewing America," an empirically rigorous study of how carefully crafted federal energy standards can fix dangerous flaws in the nation's energy grid.
