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

Hawaii

 

 

 

 

 

When we talked of going to Hawaii for a couple of weeks in February 2018 several of our friends enthusiastically recommended it. To many of them it's a nice place to go on holidays - a little further to go than Bali but with a nicer climate, better beaches and better shopping - with bargains to be had at the designer outlets.

 


Waikiki

 

To nearly one and a half million racially diverse Hawaiians it's home.

 

 


Downtown Hilo

 

To other Americans it's the newest State, the only one thousands of miles from the North American Continent, and the one that's more exotic than Florida.

 Chapter 1 - The Party

 

 

 

This morning Miranda had an inspiration - real candles!  We'll have real candles - made from real beeswax and scented with real bergamot for my final party as a celebration of my life and my death. This brief candle indeed!

In other circumstances she would be turning 60 next birthday.  With her classic figure, clear skin and dark lustrous hair, by the standards of last century she looks half her age, barely thirty, the result of a good education; modern scientific and medical knowledge; a healthy diet and lifestyle and the elimination of inherited diseases before the ban on such medical interventions. 

It's ironical that except as a result of accidents, skiing, rock climbing, paragliding and so on, Miranda's seldom had need of a doctor.  She's a beneficiary of (once legal) genetic selection and unlike some people she's never had to resort to an illegal back-yard operation to extend her life.

Opinions and Philosophy

Jihad

  

 

In my novella The Cloud I have given one of the characters an opinion about 'goodness' in which he dismisses 'original sin' as a cause of evil and suffering and proposes instead 'original goodness'.

Most sane people want to 'do good', in other words to follow that ethical system they were taught at their proverbial 'mother's knee' (all those family and extended influences that form our childhood world view).

That's the reason we now have jihadists raging, seemingly out of control, across areas of Syria and Iraq and threatening the entire Middle East with their version of 'goodness'.
