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

China

 

 

I first visited China in November 1986.  I was representing the New South Wales Government on a multinational mission to our Sister State Guangdong.  My photo taken for the trip is still in the State archive [click here].  The theme was regional and small business development.  The group heard presentations from Chinese bureaucrats and visited a number of factories in rural and industrial areas in Southern China.  It was clear then that China was developing at a very fast rate economically.

Chapter 1 - Caught short

 

 

 

 

Christmas 2069 approaches and in the midst of the greatest retail spending frenzy for decades Bianca has been trying on clothes..  They're at Bergeroff Goodman, an up-market store. Bianca has been brought here by Margery who frequents such expensive places.  Unlike many other retail establishments in the world at this time of year, the store is not over-packed with shoppers.

Elsewhere many customers will expend their entire available credit and have even accumulated credit from earlier in the year to allow for this annual celebratory splurge.  Much of it will be expended on personal services, personal wellbeing, exercise, entertainment and of course religious practice and many will exchange gifts of credit towards these services with friends and loved ones.  But this store is very up-market and discrete.

This Monday lunchtime Margery is encouraging Bianca to buy a top quality black wool and mohair suit with a knee length skirt, similar to the one Margery is wearing.  Bianca had been resisting and equivocating when the call of nature gratuitously cut short their struggle.  The older woman had assumed Bianca's resistance was for financial reasons, insisting that a good suit is not an extravagance but an investment in Bianca's future.

Renewable Electricity

 

 

As the energy is essentially free, renewable electricity costs, like those of nuclear electricity, are almost entirely dependent on the up-front construction costs and the method of financing these.  Minimising the initial investment, relative to the expected energy yield, is critical to commercial viability.  But revenue is also dependent on when, and where, the energy can be delivered to meet the demand patterns of energy consumers.

For example, if it requires four times the capital investment in equipment to extract one megawatt hour (1 MWh) of useable electricity from sunlight, as compared to extracting it from wind, engineers need to find ways of quartering the cost of solar capture and conversion equipment; or increasing the energy converted to electricity fourfold; to make solar directly competitive.
