Tis the season - for new LED lightbulbs!

Today is the day to use those gift cards you got to help save yourself some money and the planet too. Based on this morning's trip to Home Depot, I have updated my lifetime cost calculations for LED/CFL/Incandescent bulbs. The chart is based on recessed lights, 65-75W equivalent R-30 bulbs, 5 yrs use per day, $.12 kWh electricity price. These lights are very common in the houses in my neighborhood. The LED bulbs are down to $30 each, so get our there and replace those old bulbs!

On a related note, 40w equivalent LED bulbs in A-19 (standard bulb shape) are selling for only $10 a piece. This is a great deal - I got 5 of these today for a dimmable fixture and they work great! Anyone care to work the payback numbers for those? Please leave a comment if you do!

New report from Dr. Janette Sherman, MD

PRESS RELEASE - Janette D. Sherman, MD
12-19-2011

This report, "An Unexpected Mortality Increase in the United States Follows Arrival of the Radioactive Plume from Fukushima:  Is There a Correlation?" published in the Internat. J. of Health Sciences  today, is not new science, but confirms research done over the decades as to adverse effects caused by radioisotopes to the unborn and the very young because of their rapidly developing cells, immature immunological systems and relatively small weight.

As background, in the 1950s, I worked for the Atomic Energy Commission (the forerunner of the Nuclear Regulatory Commission) at the Radiation Laboratory, University of California in Berkeley and the US Navy Radiation Laboratory at Hunter's Point in San Francisco.  Near 60 years ago, we learned that radiation could damage animals and plants and cause cancer, genetic damage, and other problems.

The issue of the danger from nuclear power plants is not just the engineering, but biology and chemistry. We have understood for decades where and how radioisotopes interact with life systems.

Cesium-137 and Strontium-90 have half-lives of  approx 30 years.  It takes 10 half-lives for an isotope to fully decay, thus it will take 300 years or Three Centuries before radioactive cesium and strontium will be gone. Cs134, Cs-137 and Sr-90 continue to be released from Fukushima in tons of contaminated water that is making its' way across the Pacific Ocean.  Cesium concentrates in soft tissue, strontium in bones and teeth, of the unborn and young.

Immediately after Chernobyl the level of thyroid disease increased.  Given the large amounts of radioactive iodine (I-131) released from Fukushima, thyroid disease will develop in those exposed in Japan, as well as in those exposed to lesser amounts throughout the northern hemisphere.  Public health officials need to anticipate and prepare for these findings.

The highest levels of I-131 measured by EPA in precipitation varied from a high of 390 pico Curies (pCi) in Boise to 92 in Boston, with intermediate levels in Kansas City, Salt Lake City, Jacksonville and Olympia, WA.   (Normal is @ 2 pCi)

Not every system was evaluated after Chernobyl, but of those that were:  wild and domestic animals, birds, fish, plants, fungi, bacteria, viruses - even humans - were altered by the radiation, often for generations. Birds in the 30-kilometer "exclusion zone" of Chernobyl display small brain size, alterations of normal coloration, poor survival of offspring, and poor adaptability to stress,

Recent, independent studies conducted in Scandinavia shows a decline on academic performance in children exposed during the Chernobyl fallout. 80% of children in Belarus are considered un-well by government standards.

Unless the earth stops tuning, and the laws of biology, chemistry and physics are rescinded, we will continue to see sickness and harm spread to the children of Fukushima, the same that occurred after Chernobyl.  We ignore history at our peril.

Good videos on sustainability

Recently I have watched a couple of good videos explaining some of what is going on in the world in relation to energy, economics, environment and sustainability in general.

If you have limited time, this video by Tom Murphy is only 23 minutes but provides a very good explanation of why continued exponential growth is simply impossible:

http://fora.tv/2011/10/26/Growth_Has_an_Expiration_Date

Tom Murphy is an associate professor of physics at the University of California, San Diego and he also blogs about sustainability issues at: Do The Math. Here you can read more of Tom's analysis which is backed up by his knowledge of physics and his calculations based on actual physics formulas and real data.

For a much longer but still very good video to watch (it's around 3 hrs but comes in 19 parts), I recommend the "Crash Course" by Chris Martenson. Chris is a gentleman who has a PhD in neurotoxicology, an MBA in Finance and has studied in great detail some of the current economic, environmental and energy issues the world is facing today.

This video is available from his website (Chris Martenson dot com), or Sustainable Loudoun has a DVD copy. Chris also allows people to make copies of his DVD, please contact me if you would like a copy of your own.

These examples are just two of many resources available to learn about this unique time in history that we live in. If anyone has more examples they would like to share, please reply or comment on this post and I will update it with more resources.

Note: Myself or Sustainable Loudoun are not associated with either of the above mentioned individuals, I just think they have made some very informative presentations.

Uranium Mining in Virginia






By Tony Noerpel


On November 11, 2011, Friday evening starting at 6:00 PM, at George Washington University, Ashburn Campus off of Route 7, the Piedmont Environmental Council, George Washington University and Sustainable Loudoun are hosting a discussion forum on uranium mining in Virginia.  A longer version of this article will be published by the Blue Ridge Leader.

In 1982, the Virginia state legislature passed what amounts to an effective moratorium on uranium mining in the state.  Virginia Uranium is lobbying to have this moratorium lifted so that they can surface mine the uranium deposit at Coles Hill, in Pittsylvania County.  The accompanying figure from the Piedmont Environmental Council, shows potential uranium resources in our area.  The map is based on data published by the United States Geological Survey in 1998 which is a geochemical analysis of stream sediment and other solid samples.  Note that there is a large blotch of red in Western Loudoun County under many of our homes and farms.  

While nuclear power has several serious problems associated with cost, safety and waste the most obvious problem, and the one most relevant to the issue at hand, is the future supply of uranium.  If there is not a huge reliable supply then nuclear power is not the solution to our energy problems.  If the supply is very limited then it is not even a small part of the solution space.  If humanity commits itself to nuclear power and the supply is limited then uranium mining may be extended beyond the proposed Coles Hill site into other parts of the state.  

Virginia Uranium publishes the following exchange on their web site, under the heading “Myth and Fact”:

The Piedmont Environmental Council has circulated a map of Virginia entitled “Water supplies potentially impacted by uranium mining” that includes Fairfax, Town of Orange, Fredericksburg and Spotsylvania, as well as Halifax, Clarksville and Mecklenburg. – Piedmont Environmental Council website, February 21, 2011

These water supplies are not threatened by Coles Hill or any other uranium deposit.  As state regulators have testified, Coles Hill is the only deposit in Virginia worth mining. “With the exception of Coles Hill, none of the occurrences identified to date are presently considered economic deposits due to low grade and/or limited extent.” – William L. Lassetter, Jr., Economic Geology Manager, Virginia Department of Mines, Minerals, and Energy, Division of Geology and Mineral Resources.

Virginia Uranium does not deny that mining Coles Hill threatens the water supply in Pittsylvania County and the quote from William Lassetter does not address the impact of uranium mining on local water supply.  In a phone call, Lassetter assured me he has no opinion on the impact of mining on water supply.  Lassetter’s use of the word presently specifically does not preclude uranium mining anywhere else in the state. Oil from Canadian tar sands deposits was considered uneconomical until shortages developed and prices rose.

This limits consideration to what the International Atomic Energy Agency (IAEA) classifies as Reasonably Assured Resources or RAR uranium deposits, according to the IAEA and NEA Red Book.  The Red Book is the most credible source for uranium deposit data and is cited by proponents and opponents of nuclear energy alike.  

Uranium resources are described by four classes: Reasonably Assured Resources (RAR), Inferred Resources (IR), Speculative Resources (SR) and Prognosticated Resources (PR).  IR, SR and PR are specifically “undiscovered”.  Of the three classes IR have the highest probability and are “not yet discovered but believed to exist”.  The table below lists the amount of uranium in metric kilo tonnes.  Worldwide, we consume 70000 tonnes per year in our reactors.  Using only RAR we have only 57 years worth of uranium supply at the current consumption rate and assuming we can recover 100% of the uranium in the ore.  If we assume a 58% recovery rate (European historic) and assume nuclear power grows by 2% per year then we will run out of RAR within 23 years.  Clearly we have considerable supply problems if we try to grow nuclear power much beyond the current level of consumption.


Class2009 resources
RAR
4004000
IR
1879000
UPR
2815000
USR
6559000
Total
15257000
Table 1 - Resources per class in metric tons

When you read that we have over 200 years worth of uranium the writer is including all of the undiscovered speculative and prognosticated resources and assuming no growth and 100% recovery of “undiscovered” resources.

Uranium Mining in Virginia:
Should we end the moratorium?

An educational forum hosted by Sustainable Loudoun
and the Piedmont Environmental Council
at George Washington University’s Loudoun Campus
Friday, November 11th, 2011 at 7:00 p.m.

For 30 years Virginia has had a statewide moratorium on uranium mining. Now, a company called “Virginia Uranium” has asked the general assembly to lift the moratorium so they can begin mining operations in Pittsylvania County.

Sustainable Loudoun believes that all citizens of Virginia should have the opportunity to learn the facts not only about the safety of this uranium mine, but about nuclear power in general as a long term energy source and alternatives to it. Toward this end, we are hosting an educational forum on the topic of uranium mining in Virginia at George Washington University’s Loudoun campus on Friday, November 11th at 7:00 pm.

Speakers will include:

Tony Noerpel (Sustainable Loudoun) on the long term viability of nuclear power

Janette Sherman, MD onFukushima and Chernobyl: Health impacts

Rob Marmet (Piedmont Environmental Council) on impact of surface mining on water supply

Virginia Uranium or Nuclear Energy Institute spokesperson (TBD on uranium mining safety measures and economic benefits.

Will Stewart (Sustainable Loudoun) on alternatives to nuclear power with cost comparisons

The speakers will be followed by a question and answer session with the panelists.

For 30 years Virginia has had a statewide moratorium on uranium mining. Now, a company called “Virginia Uranium” has asked the general assembly to lift the moratorium so they can begin mining operations in Pittsylvania County.

The state of Virginia Coal and Energy Commission (VCEC) has commissioned a study by the National Academies of Science to assist Virginia to determine whether uranium mining can be undertaken in a manner that safeguards the environment, natural and historic resources, agricultural lands and the health and well-being of its citizens. In addition, the VCEC commissioned a socioeconomic study on the impacts of uranium mining. Both studies are scheduled for completion prior to the 2012 General Assembly session.

Recent catastrophes such as the Fukushima nuclear disaster in Japan, the recent earthquake in Mineral and the recent record torrential rains from tropical storms Irene and Lee serve as reminders that we must consider many factors when deciding whether to permit potentially risky industries to operate within our state.

Sustainable Loudoun believes that all citizens of Virginia should have the opportunity to learn the facts not only about the safety of this uranium mine, but about nuclear power in general as a long term energy source and alternatives to it. Toward this end, we are hosting an educational forum on the topic of uranium mining in Virginia at George Washington University’s Loudoun campus on Friday, November 11th at 7:00 pm.

Speakers will include:

Tony Noerpel (Sustainable Loudoun)
  • The long term viability of nuclear energy given:
  • World total uranium reserves
  • Nuclear construction costs and subsidies
  • Potential for catastrophic failures
  • Lack of long term nuclear waste solutions
  • Complexity of the uranium mining, processing, enriching supply chain
  • Countries which are moving beyond nuclear

Janette Sherman, MD
  • Fukushima and Chernobyl: Health impacts

Rob Marmet (Piedmont Environmental Council)
  • Legal aspects of the moratorium
  • What is at stake.
  • Impact of surface mining on water supply and agriculture

Virginia Uranium or Nuclear Energy Institute spokesperson (TBD)
  • Uranium mining safety measures and economic benefits.

Will Stewart (Sustainable Loudoun)
  • Alternatives to nuclear
  • Cost comparison: Nuclear, wind, solar power

The speakers will be followed by a question and answer session with the panelists.
