ODAC Newsletter Sept 28

Oil prices were once again oscillating between the price depressing effects of economic uncertainty and the price enhancing effects of Middle East political uncertainties this week…Saudi Arabia has promised to keep oil markets supplied in the event of shortfalls elsewhere, but Deutsche Bank, and others question whether the kingdom is really in a position to make good on the promise. The IEA now estimates Saudi spare capacity at just under 2 million barrels/day.

ODAC Newsletter Sept 21

Oil prices fell dramatically this week to $107/barrel for Brent, on worsening economic news from China and Europe, and assurances from Saudi Arabia that it is ready to pump more oil to keep prices down. The speed of the fall on Monday however is something of a mystery and has led to an investigation by the Commodity Futures Trading Commission and the FSA.

Revolution: J.J. Abrams tells the Inconvenient Truth

It’s fifteen years after the Great Blackout. The United States, at the very least, is entirely free of electricity for reasons as yet unknown (but it sure smells like, get this, a conspiracy!) Humans have left the cities for the countryside to live in communal villages or prey on one another. The good guys sport henleys and hoes. The bad ones also wear henleys, but they ride horses and carry swords…

 

Blow-by-Blow PV System Efficiency: A Case Study for Storage

A short while back, I described my standalone (off-grid) urban photovoltaic (PV) energy system. At the time, I promised a follow-up piece evaluating the realized efficiency of the system. What was I thinking? The resulting analysis is a lot of work! But it was good for me, and hopefully it will be useful to some of you lot as well.

Review: “Reinventing Fire” by Amory Lovins

This book continues the presentation of the Lovins perspective, essentially the claim that there is great scope for conservation measures and alternative technologies to solve our problems and enable maintenance of rich world economies and lifestyles. My notes indicate that it would be far too capital costly for the US to run largely on renewable energy.

Review: Too Much Magic by James Kunstler

…Kunstler has a new work of social criticism titled Too Much Magic, his first nonfiction book since The Long Emergency came out in 2005. The book is an inquiry into a skewed, delusional perception of reality that Kunstler thinks has become “baseline normal for the American public lately.” Americans, he says, have been led astray by the incredible technological advancements of recent times. We’ve come to believe that any problem we face is solvable—as if by magic—with the application of some new technology.

Community Energy in Lewes

Ouse Valley Energy Supply Company, or Ovesco as it is commonly known, is a powerful inspiration for enthusiasts of community renewable energy….Standing on a hill above Lewes you can not only see the solar PV installations completed by Ovesco but also arrays of panels inspired by their projects. The local football club, the leisure centre and many local homes, have all followed the example of Ovesco. Other sites are looking to follow and there are also plans for community wind and hydro-electric schemes.
