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

The Greatest Dining Experience Ever in Bangkok

A short story

 

The Bangkok Sky-train, that repetition of great, grey megaliths of ferroconcrete looms above us.   

All along the main roads, under the overhead railway above, small igloo tents and market stalls provide a carnival atmosphere to Bangkok.  It’s like a giant school fete - except that people are getting killed – half a dozen shot and a couple of grenades lobbed-in to date.

Periodically, as we pass along the pedestrian thronged roads, closed to all but involved vehicles, we encounter flattop trucks mounted with huge video screens or deafening loud speakers.

The Password

 

 

 

 

How I miss Rio.  Rio de Janeiro the most stunningly picturesque city on Earth with its dark green mountains and generous bays, embelezado with broad white, sandy beaches.  Rio forever in my heart.   Rio my a minha pátria, my homeland, where I spent the most wonderful days of my life with linda, linda mãe, my beautiful, beautiful mother. Clambering up Corcovado Mountain together, to our favela amongst the trees.

Thinking back, I realise that she was not much older than I was, maybe fifteen years.  Who knows?

Her greatest gift to me was English.

Whither Peak Oil

 

 

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.
