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

Southern England

 

 

 

In mid July 2016 Wendy and I took flight again to Europe.  Those who follow these travel diaries will note that part of out trip last year was cut when Wendy's mum took ill.  In particular we missed out on a planned trip to Romania and eastern Germany.  This time our British sojourn would be interrupted for a few days by a side-trip to Copenhagen and Roskilde in Denmark.

The Soul of the Matter

 

 

 

 

 

 

It's hot, dry and dusty when they finally arrive in Jaisalmer.  But then, how often is it not? 

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 passersby 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 in the late afternoon, by road from Jodphur.   In spite of his preference to visit California again, she's finally persuaded Bruce that he might like India and should try something a bit less conservative.

Climate Change - a Myth?

 

 

 

Back in 2015 a number of friends and acquaintances told me that Climate Change is a myth.

Half a decade on and some still hold that view.  So here I've republished a slightly longer version of the same article.

Obviously the doubters are talking about 'Anthropogenic Global Warming', not disclaiming actual changes to the climate.  For those of us of a 'certain age' our own experience is sufficient to be quite sure of that the climate is continuously changing. During our lifetimes the climate has been anything but constant.  Else what is drought and flood relief about?  And the ski seasons have definitely been variable. 

Beyond our direct experience everyone, including Greta Thunberg, has to rely on others: parents; teachers; books; and so on.

Some things confirm what we are told others do not. So I like to let the grandchildren play with my microscope to see for themselves. Similarly, the existence and complex functioning of your mobile phone confirms much of modern physics in a single device and quite a bit of chemistry too. But it's existence is a bit ambivalent on the accuracy of ancient climate history. So for that I must rely on the reports of scientists who have themselves examined ice cores or tree rings or sea level records or other physical evidence that can be dated.

So I'm prepared to believe aspects of quantum theory and I'm prepared to believe the scientists who have determined sea levels showing that fourteen or fifteen thousand years ago a hypothetical Australian could walk from Hobart to New Guinea or an Irishman all the way from Galway to Denpasar in Bali.  Indeed it now seems likely that our Denisovan cousins/ancestors did exactly that during a cold snap around 65,000 years ago. Yet I'm a bit sceptical when it comes to the attributes of the god Ganesha or the efficacy of prayers to St Anthony.

It seems to me that this rise has not stopped.  During my lifetime the average sea level in Sydney Harbour has risen by nearly a foot, in keeping with long term trends.  More water in the Harbour on average obviously has temperature and therefore microclimate implications.  There are thousands of well documented examples of changes like this that have climate impacts.

But like the tides there is great variability that masks the underlying trends.   For example 2014 was a record warm year in Sydney.  But in mid 2015, when climate scepticism was at a peak, we were going through the longest cold spell in 45 years.  It snowed in Queensland!  Now in 2019 we, like California, have high temperatures; little rain; and the worst bushfires ever.
