Japan has 55 nuclear reactors at 19 sites.  Two more are under construction and another twelve are in the advanced planning stage.  Net Generating capacity is around 50 GW providing around 30% of the country's electricity (more here).  

As a result of Japan’s largest earthquake in history on March 11 and subsequent tsunami all reactors shut down automatically as they were designed to do but cooling systems associated with two sites had been damaged. 

Three reactor sites are adjacent to the earthquake epicentre and two were in the direct path of the tsunami.  The Fukushima-Daiichi plant belonging to Tokyo Electric Power Company was particularly hard hit.  It lost all grid connections, providing electricity, and its backup power plant was seriously damaged. 

 

 

Energy Solutions

 

Most informed commentators agree that Australia needs a better mix of energy sources.  We are too dependent on fossil fuel.  This results in a very high rate of carbon dioxide production per capita; and this has international and domestic implications in the context of concerns about climate change.

 

 

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. 

 

 

 

Energy

With the invention of the first practical steam engines at the turn of the seventeenth century, and mechanical energy’s increasing utility to replace the physical labour of humans and animals, human civilisation took a new turn.  

Now when a contemporary human catches public transport to work; drives the car to socialise with friends or family; washes and dries their clothes or the dishes; cooks their food; mows their lawn; uses a power tool; phones a friend or associate; or makes almost anything;  they use power once provided by slaves, servants or animals.

 

 

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.

Spain and Portugal

 

 

Spain is in the news.

Spain has now become the fourth Eurozone country, after Greece, Ireland and Portugal, to get bailout funds in the growing crisis gripping the Euro.

Unemployment is high and services are being cut to reduce debt and bring budgets into balance.  Some economists doubt this is possible within the context of a single currency shared with Germany and France. There have been violent but futile street demonstrations.

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.

World Population – again and again

 

 

David Attenborough hit the headlines yet again in 15 May 2009 with an opinion piece in New Scientist. This is a quotation:

 

‘He has become a patron of the Optimum Population Trust, a think tank on population growth and environment with a scary website showing the global population as it grows. "For the past 20 years I've never had any doubt that the source of the Earth's ills is overpopulation. I can't go on saying this sort of thing and then fail to put my head above the parapet."

 

There are nearly three times as many people on the planet as when Attenborough started making television programmes in the 1950s - a fact that has convinced him that if we don't find a solution to our population problems, nature will:
"Other horrible factors will come along and fix it, like mass starvation."

 

Bob Hawke said something similar on the program Elders with Andrew Denton:
