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).

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:

New South Wales electricity users are to suffer another round of hefty price increases; with more to come.

The Independent Pricing and Regulatory Tribunal (IPART) has announced that electricity prices for the average New South Wales resident will increase by 17.6 per cent from July.  Sydney customers will pay on average about $230 more each year, while rural customers will face an extra $316 in charges.  IPART says it is recommending the increases because of costs associated with energy firms complying with the federal government's Renewable Energy Target (RET).  The RET requires energy firms to source power from renewable sources such as solar or wind.

What is this about and how does it relate to the planned carbon tax?

Travel

Hong Kong and Shenzhen China

 

 

 

 

 

Following our Japan trip in May 2017 we all returned to Hong Kong, after which Craig and Sonia headed home and Wendy and I headed to Shenzhen in China. 

I have mentioned both these locations as a result of previous travels.  They form what is effectively a single conurbation divided by the Hong Kong/Mainland border and this line also divides the population economically and in terms of population density.

These days there is a great deal of two way traffic between the two.  It's very easy if one has the appropriate passes; and just a little less so for foreign tourists like us.  Australians don't need a visa to Hong Kong but do need one to go into China unless flying through and stopping at certain locations for less than 72 hours.  Getting a visa requires a visit to the Chinese consulate at home or sitting around in a reception room on the Hong Kong side of the border, for about an hour in a ticket-queue, waiting for a (less expensive) temporary visa to be issued.

With documents in hand it's no more difficult than walking from one metro platform to the next, a five minute walk, interrupted in this case by queues at the immigration desks.  Both metros are world class and very similar, with the metro on the Chinese side a little more modern. It's also considerably less expensive. From here you can also take a very fast train to Guangzhou (see our recent visit there on this website) and from there to other major cities in China.

Fiction, Recollections & News

The McKie Family

 

 

 

Introduction

 

 

This is the story of the McKie family down a path through the gardens of the past that led to where I'm standing.  Other paths converged and merged as the McKies met and wed and bred.  Where possible I've glimpsed backwards up those paths as far as records would allow. 

The setting is Newcastle upon Tyne in northeast England and my path winds through a time when the gardens there flowered with exotic blooms and their seeds and nectar changed the entire world.  This was the blossoming of the late industrial and early scientific revolution and it flowered most brilliantly in Newcastle.

I've been to trace a couple of lines of ancestry back six generations to around the turn of the 19th century. Six generations ago, around the turn of the century, lived sixty-four individuals who each contributed a little less 1.6% of their genome to me, half of them on my mother's side and half on my father's.  Yet I can't name half a dozen of them.  But I do know one was called McKie.  So this is about his descendents; and the path they took; and some things a few of them contributed to Newcastle's fortunes; and who they met on the way.

In six generations, unless there is duplication due to copulating cousins, we all have 126 ancestors.  Over half of mine remain obscure to me but I know the majority had one thing in common, they lived in or around Newcastle upon Tyne.  Thus they contributed to the prosperity, fertility and skill of that blossoming town during the century and a half when the garden there was at its most fecund. So it's also a tale of one city.

My mother's family is the subject of a separate article on this website.

Australia's carbon tax

 

 

Well, the Gillard government has done it; they have announced the long awaited price on carbon.  But this time it's not the highly compromised CPRS previously announced by Kevin Rudd.  

Accusations of lying and broken promises aside, the problem of using a tax rather than the earlier proposed cap-and-trade mechanism is devising a means by which the revenue raised will be returned to stimulate investment in new non-carbon based energy.
