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

Argentina & Uruguay

 

 

In October 2011 our little group: Sonia, Craig, Wendy and Richard visited Argentina. We spent two periods of time in Buenos Aires; at the start and at the end of our trip; and we two nights at the Iguassu Falls.

Now I am seventy

 On the occasion of an afternoon tea to mark this significant milestone...

 

When I was one, I was just begun;
When I was two, I was nearly new;
When I was Three, I was hardly me;

But then I was sixty, and as clever as clever;
Wouldn't it be nice to stay sixty for ever and ever?

(With apologies to AA Milne)

 

Hang on!  Now I'm seventy?  How did that happen?

Frederick Sanger - a life well spent

 

 

I have reached a point in my life when the death of a valued colleague seems to be a monthly occurrence.  I remember my parents saying the same thing. 

We go thought phases.  First it is the arrival of adulthood when all one's friends are reaching 21 or 18, as the case may be.  Then they are all getting married.  Then the babies arrive.  Then it is our children's turn and we see them entering the same cycle.  And now the Grim Reaper appears regularly. 

As I have repeatedly affirmed elsewhere on this website, each of us has a profound impact on the future.  Often without our awareness or deliberate choice, we are by commission or omission, continuously taking actions that change our life's path and therefore the lives of others.  Thus our every decision has an impact on the very existence of those yet to be born.
