ABC reports – Perth Children’s Hospital: More delays as treatment fails to solve drinking water lead problem 30 Jun 2017 – I have blogged earlier this year. How have our Govts unlearned such a simple thing as a safe water supply?
I think it is a few months off 9 years ago in 2008 that the NSW Govt agreed to sell big Chinese coalminer Shenhua the Watermark orebody near Gunnedah for $300 million. Shenhua was hit with other payments over $350 million then bought land and would have spent over a $Billion by now see blog 2 years ago. Anybody reading Shenhua Watermark news headlines might conclude they were a community welfare org. not a global ranking coal miner.
Sign petition EN0264 by John McLean – Australia to follow the lead of the USA and immediately withdraw from the Paris Climate Agreement – come on it is easy to do takes a minute or two only requires your name & email – have your say – be counted.
Just saw this on Stuff – First-of-its-kind case as student takes Government to court over climate change 23 Jun 2017 – can any Kiwis translate? BP says NZ emissions are 35.2 million t CO2 compared to World 33,432 million t – which I make 0.1053% I doubt if anything the NZ Govt. could do would affect climate. I wonder who is financing the case – is there a risk over costs? Will Govt. run dead?
Curious about global nuclear power trends and implications for the uranium market – I extracted the latest from the latest BP Statistical Review of World Energy that now includes 2016. Global electricity generation by fuel type. I had to calculate the fossil fuel column by subtraction.

The ABC Business Editor Ian Verrender writes – quote – “Ever since the carbon tax was removed, power prices have only headed one way; upwards.” Not according to my Canberra power bills Ian which show clearly how retail prices fell after mid 2014 when the Carbon Tax was repealed. When I get time I can update this chart but there is enough here for now. After 2014 there was talk then action on the closing of Port Augusta coal fired generation which started that huge upsurge in AEMO wholesale prices. Then the closing of Hazelwood took more dispatchable power out of the grid. No wonder prices are on fire.
Thanks to reader on Mainland Aotearoa this story from Stuff – Power price surge too hot for some customers 20 June 2017 – New Zealand is blessed with a high proportion of hydro power but a dry winter so far has lead to higher output at the Huntly coal fired generator south of Auckland. Summary of the Electricity sector in New Zealand – We are having a dry start to winter too but our hydro sector is much smaller than New Zealand.
I blogged over two years ago on the BoM moving their main Adelaide weather instruments site from Kent Town to West Terrace not far from where the site was from the 1800’s up to 1979. In April 2015 I said – Bureau of Meteorology delusions about the urban heat island revealed in news of relocation (again) of Adelaide weather instruments – And now we see West Terrace is starting its new life warmer at night than Kent Town – assuming the BoM have had time to iron out any instrument faults – there is a gap of 4 hours at West Terrace on the 15th. If readers wanted to do any night time vehicle/temperature traverses – data might be interesting.

Tasmanian electricity is supplied by their Govt owned mostly hydro and lesser wind & gas fired generation.
Why is that Tasmanian wholesale AEMO prices spike to over $2000 per MW hour twice in recent days?
There is only one supplier – Hydro-Electric Corporation owned by the Tasmanian Goverment. Nemwatch for current generation and AEMO for prices and demand charts and AEMO NEM dispatch overview. Obviously Hydro Tasmania is in a dry spell and in order to conserve water levels will buy Victorian power through BassLink when prices suit them – see the AEMO NEM dispatch overview for interstate flows in real time.
With Finkel being debated and loads of misinformation around – here are AEMO state by state generation capacities by source. The figures can be rubbery, on 10 Feb 2017 NSW initiated load shedding with demand not much over 14,000MW and imports at over 1,000MW. There were failures of coal, gas and hydro generation to match AEMO assumptions. On the 8 Feb South Australia went close to load shedding with demand a little over 3,000MW. AEMO says SA wind totals 1595MW but I can only find 1208MW by tallying wind generators on the AEMO list.
