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:

More Silk Road Adventures - The Caucasus

 

 

 

Having, in several trips, followed the Silk Road from Xian and Urumqi in China across Tajikistan and Uzbekistan our next visit had to be to the Caucuses.  So in May 2019 we purchased an organised tour to Azerbaijan, Georgia and Armenia from ExPat Explore.  If this is all that interests you you might want to skip straight to Azerbaijan.

More on 'herd immunity'

 

 

In my paper Love in the time of Coronavirus I suggested that an option for managing Covid-19 was to sequester the vulnerable in isolation and allow the remainder of the population to achieve 'Natural Herd Immunity'.

Both the UK and Sweden announced that this was the strategy they preferred although the UK was soon equivocal.

The other option I suggested was isolation of every case with comprehensive contact tracing and testing; supported by closed borders to all but essential travellers and strict quarantine.   

New Zealand; South Korea; Taiwan; Vietnam and, with reservations, Australia opted for this course - along with several other countries, including China - accepting the economic and social costs involved in saving tens of thousands of lives as the lesser of two evils.  

Yet this is a gamble as these populations will remain totally vulnerable until a vaccine is available and distributed to sufficient people to confer 'Herd Immunity'.

In the event, every country in which the virus has taken hold has been obliged to implement some degree of social distancing to manage the number of deaths and has thus suffered the corresponding economic costs of jobs lost or suspended; rents unpaid; incomes lost; and as yet unquantified psychological injury.

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.
