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

Malaysia

 

 

In February 2011 we travelled to Malaysia.  I was surprised to see modern housing estates in substantial numbers during our first cab ride from the Airport to Kuala Lumpur.  It seemed more reminiscent of the United Arab Emirates than of the poorer Middle East or of other developing countries in SE Asia.  Our hotel was similarly well appointed.

The Soul of the Matter

 

 

 

 

It was hot, dry and dusty when they finally arrived in Jaisalmer.  But then, how often is it not hot and dusty here? 

In the markets a wizened woman, of indeterminate age, is using a straw broom to aggressively sweep the area in front of her shop. The dust will soon be kicked-back by passers-by; or swept back by her neighbours; requiring her to sweep again, and again.  She will do the same again tomorrow; and the day after; and the day after that.

Jennifer's mind is elsewhere. She's has dreamt of visiting exotic India ever since a client at the hairdressers told her, with enthralling details, of her adventures here.

They've arrived in the dusty city late in the afternoon, by road from Jodhpur.  In spite of his preference to visit California or Las Vegas again, she's finally persuaded Bruce that he might like India. He should try something a bit more adventurous for a change.

Below the entrance to the famous Jaisalmer Fort, is a small square that marks the start of the road winding up, then turning at right-angles, through the protective elephant-proof gates.  In this little square, motorised trishaws: Tuk-tuks, jostle restlessly like milling cattle.  They are waiting for tourists, like our travellers, who may hire them tomorrow to see the town or, if they are lazy or tired, just to mount the steep hill up to the Fort.

Opinions and Philosophy

Bertrand Russell

 

 

 

Bertrand Russell (Bertrand Arthur William Russell, 3rd Earl Russell, OM, FRS (18 May 1872 – 2 February 1970)) has been a major influence on my life.  I asked for and was given a copy of his collected Basic Writings of Bertrand Russell for my 21st birthday and although I never agreed entirely with every one of his opinions I have always respected them.

In 1950 Russell won the Nobel Prize in literature but remained a controversial figure.  He was responsible for the Russell–Einstein Manifesto in 1955. The signatories included Albert Einstein, just before his death, and ten other eminent intellectuals and scientists. They warned of the dangers of nuclear weapons and called on governments to find alternative ways of resolving conflict.   Russell went on to become the first president of the campaign for nuclear disarmament (CND) and subsequently organised opposition to the Vietnam War. He could be seen in 50's news-reels at the head of CND demonstrations with his long divorced second wife Dora, for which he was jailed again at the age of 89.  

In 1958 Gerald Holtom, created a logo for the movement by stylising, superimposing and circling the semaphore letters ND.

Some four years earlier I'd gained my semaphore badge in the Cubs, so like many children of my vintage, I already knew that:  = N(uclear)   = D(isarmament)

The logo soon became ubiquitous, graphitied onto walls and pavements, and widely used as a peace symbol in the 60s and 70s, particularly in hippie communes and crudely painted on VW camper-vans.

 

 (otherwise known as the phallic Mercedes).
