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

Ireland

 

 

 

 

In October 2018 we travelled to Ireland. Later we would go on to England (the south coast and London) before travelling overland (and underwater) by rail to Belgium and then on to Berlin to visit our grandchildren there. 

The island of Ireland is not very big, about a quarter as large again as Tasmania, with a population not much bigger than Sydney (4.75 million in the Republic of Ireland with another 1.85 million in Northern Ireland).  So it's mainly rural and not very densely populated. 

It was unusually warm for October in Europe, including Germany, and Ireland is a very pleasant part of the world, not unlike Tasmania, and in many ways familiar, due to a shared language and culture.

Les Misérables - The Musical

 

The musical Les Misérables has returned to Sydney.   By now we have both seen several versions.    

But we agreed that this new version is exceptional, with several quite spectacular staging innovations and an excellent cast of singers with perhaps one exception who was nevertheless very good.

Despite an audience that was obviously very familiar with the material (if I'm to judge by the not so sotto voce anticipatory comments from the woman next to us) the production managed to evoke the required tears and laughter in the appropriate places.  The packed theatre was clearly delighted and, opera style, the audience shouted approval at and applauded several of the vocal performances, some were moved to a standing ovation at the end.

The Carbon Tax

  2 July 2012

 

 

I’ve been following the debate on the Carbon Tax on this site since it began (try putting 'carbon' into the search box).

Now the tax is in place and soon its impact on our economy will become apparent.

There are two technical aims:

    1. to reduce the energy intensiveness of Australian businesses and households;
    2. to encourage the introduction of technology that is less carbon intensive.
