[12] Denmark is has the largest proportion of wind generation in the world. It is also has the greatest fossil dependency (mainly on imported coal) and highest cost electricity in the EU, over seven times that in France.

 

 

[13] France produced 536.9 TWh of electricity in 2003; is the largest net exporter of electricity in the EU (103.6 TWh in 2003); and has the highest proportion of nuclear electricity in the World.

[17] This would suggest that there are some turbines so badly sited that they will not recover the energy consumed in their construction within their 20 year working lifetime (of course this may be a lot longer than 20 years as they hardly get used). Their carbon footprint rises steeply as their capacity factor falls.

[21] Counter intuitively, water vapour reduces air density. The molecular weight of water is 18. As a gas water vapour displaces nitrogen molecules (mw: 28) and oxygen (mw: 32).

[24] Average pool price in the NEM last year was AUS$42/MWh = 4.2 cents /kWh. The average commercial return to wind farms (after RECs) was around 9 cents /kWh delivered.

[28] The present ten largest producers of nuclear energy are in order: USA, France, Japan, Russia, Germany, South Korea, Ukraine, Canada, UK and Sweden. Except for Germany and Sweden, all have new nuclear plant under construction or announced. Worldwide there are presently 53 nuclear power stations under construction and another 432 announced or proposed. There are 31 countries with one or more operating nuclear power stations and 9 more with planned stations, including Indonesia.

 

[29] China has 18 new stations under construction (to raise generating capacity by 70 GWe by 2020); 35 planned; and more than 90 proposed. India has 6 new stations under construction (to raise capacity by 41 GWe by 2020); 23 planned (to raise capacity to 470 GWe by 2050); and 15 proposed.

India

October 2009

 

 

 

 

In summary

 

India was amazing. It was just as I had been told, read, seen on TV and so on but quite different to what I expected; a physical experience (noise, reactions of and interactions with people, smells and other sensations) rather than an intellectual appreciation.

We all die of something.

After 70 it's less likely to be as a result of risky behaviour or suicide and more likely to be heart disease followed by a stroke or cancer. Unfortunately as we age, like a horse in a race coming up from behind, dementia begins to take a larger toll and pulmonary disease sees off many of the remainder. Heart failure is probably the least troublesome choice, if you had one, or suicide.

In 2020 COVID-19 has become a significant killer overseas but in Australia less than a thousand died and the risk from influenza, pneumonia and lower respiratory conditions had also fallen as there was less respiratory infection due to pandemic precautions and increased influenza immunisation. So overall, in Australia in 2020, deaths were below the annual norm.  Yet 2021 will bring a new story and we've already had a new COVID-19 hotspot closing borders again right before Christmas*.

So what will kill me?

Some years back, in October 2016, at the age of 71, my aorta began to show it's age and I dropped into the repair shop where a new heart valve - a pericardial bio-prosthesis - was fitted. See The Meaning of Death elsewhere on this website. This has reduced my chances of heart failure so now I need to fear cancer; and later, dementia.  

More fun and games.
