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:

Travel

Central Australia

 

 

In June 2021 Wendy and I, with our friends Craig and Sonia (see: India; Taiwan; JapanChina; and several countries in South America)  flew to Ayer's Rock where we hired a car for a short tour of Central Australia: Uluru - Alice Springs - Kings Canyon - back to Uluru. Around fifteen hundred kilometres - with side trips to the West MacDonnell Ranges; and so on.

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.

Holden - The Demise of an Iconic Brand

 

I drive a Holden. 

It’s my second. The first was a shiny black Commodore.  A V6 Lumina edition.

I have owned well over a dozen cars and driven a lot more, in numerous countries, but these are my first from General Motors.

The new one is a white Calais Sportswagon and it's the best car I've ever owned.

Based on the German Opel, it has traction control conferring impeccable braking and steering and ample power and acceleration even with four adults and luggage.  Add to that: leather seats; climate control; head-up display; voice commands for entertainment, phone and so on; and it's a luxurious ride.

Yet I’m starting to think that I can put an end to any car brand, just by buying one.

Holden finally ceased manufacturing in Australia just after my present model rolled off the production line.
