The following paper was written back in 2007.  Since that time the Global Financial Crisis (GFC) struck and oil prices have not risen as projected.  But we are now hearing about peak oil again and there have been two programmes on radio and TV in the last fortnight floating the prospect of peak oil again. 

At the end of 2006 the documentary film A Crude Awakening warned that peak oil, ‘the point in time when the maximum rate of petroleum production is reached, after which the rate of production enters its terminal decline’, is at hand. 

Perhaps the most important argument in A Crude Awakening is that energy, including oil, replaces human labour and does so very efficiently.  It is the harnessing of energy that has allowed human civilisation to free people from slavery and serfdom and it is the harnessing of energy that has fuelled technological progress. 

It has also fuelled an increase in human population from less than a billion in 1800 to over six and a half billion today.

The most obvious defect in the documentary is that it represents oil as the only source of energy available to mankind.  This is not the case.  Until quite recently coal was the dominant energy source.  Coal fuelled the industrial revolution.  In some parts of the world hydroelectric power was also an important driver of industrialisation before oil and, where available, is still the most environmentally friendly and least expensive energy source we have. 

It is true that petroleum (oil and gas) has recently taken over the leading position as principle energy source; and contributor to carbon dioxide production.  Petroleum is more convenient and has higher energy density than most other options (see below) and produces less carbon dioxide per unit of energy than coal. It dominated transport and chemical production for the last two thirds of the 20th century and will continue to do so for at least the first half of the 21st.

The following diagram shows the sources of energy (for all purposes) in Australia in 2007/8[1].

It was oil that made the Second World War possible, oil that provided a car to every family soon after and oil that opened the world to inexpensive air travel. 

A Crude Awakening makes the point that we have already half used this amazing resource, in a shockingly spendthrift way, over an extraordinarily short period of time.

Travel

Southern England

 

 

 

In mid July 2016 Wendy and I took flight again to Europe.  Those who follow these travel diaries will note that part of out trip last year was cut when Wendy's mum took ill.  In particular we missed out on a planned trip to Romania and eastern Germany.  This time our British sojourn would be interrupted for a few days by a side-trip to Copenhagen and Roskilde in Denmark.

The Book of Mormon

 

 

 

 

Back in the mid 1960's when I was at university and still living at home with my parents in Thornleigh, two dark suited, white shirted, dark tied, earnest young men, fresh from the United States, appeared at our door.

Having discovered that they weren't from IBM my mother was all for shooing them away.  But I was taking an interest in philosophy and psychology and here were two interesting examples of religious fervour.

As I often have with similar missionaries (see: Daniel, the Jehovah’s Witness in Easter on this Website), I invited them in and they were very pleased to tell me about their book.  I remember them poised on the front of our couch, not daring or willing to sit back in comfort, as they eagerly told me about their revelation.  

And so it came to pass that a week ago when we travelled to Melbourne to stay with my step-son Lachlan and his family and to see the musical: The Book of Mormon I was immediately taken back to 1964.

Carbon Capture and Storage

 

 

(Carbon Sequestration)

 

 

The following abbreviated paper is extracted from a longer, wider-ranging, paper with reference to energy policy in New South Wales and Australia, that was written in 2008. 
This extract relates solely to CCS.
The original paper that is critical of some 2008 policy initiatives intended to mitigate carbon dioxide emissions can still be read in full on this website:

This illustration shows the two principal categories of Carbon Capture and Storage (Carbon Sequestration) - methods of disposing of carbon dioxide (CO2) so that it doesn't enter the atmosphere.  Sequestering it underground is known as Geosequestration while artificially accelerating natural biological absorption is Biosequestration.

There is a third alternative of deep ocean sequestration but this is highly problematic as one of the adverse impacts of rising CO2 is ocean acidification - already impacting fisheries. 

This paper examines both Geosequestration and Biosequestration and concludes that while Biosequestration has longer term potential Geosequestration on sufficient scale to make a difference is impractical.
