South Australia has run aground on the long foreseen wind energy reef - is this a lee shore?

Those of you who have followed my energy commentaries published here over the past six years will know that this situation was the entirely predictable outcome of South Australia pressing on with an unrealistic renewable energy target dependent on wind generated electricity, subsidised by market distorting Large-scale Generation Certificates (LGCs) (previously called RECs in some places on this website - the name was changed after their publication).

Since I first published an article on this subject I've been taken to task by a young family member for being too negative about the prospects of a Hydrogen Economy, mainly because I failed to mention 'clean green hydrogen' generated from surplus electricity, employing electrolysis.

Back in 1874 Jules Verne had a similar vision but failed to identify the source of the energy, 'doubtless electricity', required to disassociate the hydrogen and oxygen. 

Coal; oil and gas; peat; wood; bagasse; wind; waves; solar radiation; uranium; and so on; are sources of energy.  But electricity is not. 

Electricity (and hydrogen derived from it) is simply a means of transporting and utilising energy - see How does electricity work? on this website.

Introduction

 

The present government interventions in electricity markets, intended to move the industry from coal to renewable energy sources, are responsible for most of the rapidly rising cost of electricity in Australia.  These interventions have introduced unanticipated distortions and inefficiencies in the way that electricity is delivered.

Industry experts point to looming problems in supply and even higher price increases.

A 'root and branch' review of these mechanisms is urgently required to prevent ever increasing prices and to prevent further potentially crippling distortions.

The electrically literate may find this somewhat simplified article redundant; or possibly amusing. They should check out Wikipedia for any gaps in their knowledge.

But I hope this will help those for whom Wikipedia is a bit too complicated and/or detailed.

The Chimera‡ - also known as carbon capture and storage (CCS) or Carbon Sequestration

Whenever the prospect of increased carbon consumption is debated someone is sure to hold out the imminent availability of Clean Coal Technology; always just a few years away. 

I have discussed this at length in the article Carbon Sequestration (Carbon Capture and Storage) on this website. 

In that detailed analysis I dismissed CCS as a realistic solution to reducing carbon dioxide emissions for the following reasons:

Malta

 

 

Almost everyone in Australia knows someone who hailed directly from Malta or is the child of Maltese parents. There are about a quarter as many Maltese Australians as there are Maltese Maltese so it is an interesting place to visit; where almost every cab driver or waiter announces that he or she has relatives in Sydney or Melbourne.

A Twisted Pigs Tale

 

This is a little exercise in creative writing.  The brief was to reimagine the Three Pigs from a different perspective.   The original is a parable about the virtues of forward thinking, providence and hard work, so that only the most abstemious pig survives the metaphorical wolf.  I thought it was a bit tough on the middle pig who is just trying to find a balance between work and play.   So here is my version:

Australia and Empire

 

 

 

The recent Australia Day verses Invasion Day dispute made me recall yet again the late, sometimes lamented, British Empire.

Because, after all, the Empire was the genesis of Australia Day.

For a brief history of that institution I can recommend Empire: How Britain Made the Modern World by Scottish historian Niall Campbell Ferguson.

My choice of this book was serendipitous, unless I was subconsciously aware that Australia Day was approaching.  I was cutting through our local bookshop on my way to catch a bus and wanted something to read.  I noticed this thick tomb, a new addition to the $10 Penguin Books (actually $13). 

On the bus I began to read and very soon I was hooked when I discovered references to places I'd been and written of myself.  Several of these 'potted histories' can be found in my various travel writings on this website (follow the links): India and the Raj; Malaya; Burma (Myanmar); Hong Kong; China; Taiwan; Egypt and the Middle East; Israel; and Europe (a number).  

Over the next ten days I made time to read the remainder of the book, finishing it on the morning of Australia Day, January the 26th, with a sense that Ferguson's Empire had been more about the sub-continent than the Empire I remembered.
