Log Pricing Up Sharply From 2010

October 26, 2011

Today from Pope Resources: “…Typically, a heavier mix of whitewoods would result in lower average log realizations, but the strong log demand from China that was largely indifferent as to species counteracted this expected price-dampening effect.

” As anticipated, export and total realized log prices each softened 5% in the third quarter of 2011 relative to the second quarter of 2011, with export log prices falling $31 per MBF and total realized log prices falling $27 per MBF. However, log prices were still up sharply from 2010 levels. For the first nine months of 2011, our average realized log price increased $81 per MBF, or 17%, from $487 per MBF in 2010 to $568 per MBF in 2011. This occurred even in the face of continued softness in domestic demand. Within this total, Douglas-fir sawlog prices increased $85 per MBF, or 16%, from $527 per MBF in 2010 to $612 per MBF in 2011, while whitewood sawlogs increased $103 per MBF, or 23%, from $446 per MBF in 2010 to $549 per MBF in 2011. Across all species, export log prices increased $96 per MBF, or 18%, from $529 per MBF in 2010 to $625 per MBF in 2011. In addition, while there was only a 2%, or $8 per MBF, spread between export and domestic log market pricing in the first nine months of 2010, this export spread increased to 11%, or $64 per MBF, for the first nine months of 2011.”


Fluorescent Lamps

October 24, 2011

Starting July 14, 2012, manufacturing or importing most T12 fluorescent lamps will be prohibited. The supply of T12s will eventually run out and customers will have no choice but to upgrade to higher efficiency T8 or T5 lamps and ballasts.

 T12s are being phased out because the federal government passed legislation increasing the minimum efficiency standards of linear fluorescent lamps. Most T12 lamps will not meet these minimum standards.

Creating a new business model for utilities: a white paper 

* Texas Instruments now offers new integrated circuits targeted at AC power lighting applications such as LED retrofit lamps.

* GE enters the LED retrofit market. The LED chips seen in their video are not GE products; the company sold their LED division years ago.

* Hydraulic fracturing interest groups, both pro and con, have set up a site where you can track individual wells.


* Lessons we learned in Physics 3C explain why those CERN neutrinos really did not go faster that C.

* Con Edison has earned recognition from the international Carbon Disclosure Project; in the 2011 rankings, they placed first among utilities in the S&P 500 Carbon Disclosure Leadership Index. Con Ed transmits and distributes electricity and does not generate electricity, which may have an impact on their carbon footprint in relation to other utilities. They also fire boilers to produce commercial steam.

* The NYC DEC Commissioner Joe Martens testified before the NYS Assembly today regarding hydraulic fracturing. Martens said, “While gas drilling has proceeded at a sprint pace in Pennsylvania and other states, New York and DEC have proceeded cautiously and deliberately in developing a responsible approach to gas drilling. I’ve said time and again that DEC will not issue permits for this activity until I’m satisfied it can be done safely and responsibly and I continue to make that pledge.”
