Rhosty: "And just labelling something you don't like as BS, doesn't make it so." - In general this is true, however it doesn't mean that when someone says you are talking rubbish that they're always wrong. And in this case mhaze is right and you're wrong!

Many times over the past few years your misunderstandings and flaws in your scientific waffle and drivel have been pointed out to you and corrected. However, you NEVER seem to acknowledge or admit that you could possibly be wrong. It is YOU that needs to read a book on science (and while you're at it read a book on economics!).

(Bye-the-way- I have personally corrected you a while back about your 50%+ oxygen claim. At the time I called you out, said it wasn't so and even went on to explain that oxygen is TOXIC to us at this level (it is toxic to a lot of other species as well). I supplied a web-link to wikipedia as a reference. But you just ignored it and are still making this bogus claim.

PLease, please, please: if you're going to make scientific sounding claims- at least do some research first!)

Aidan,

There is a very strong correlation between the amount of renewables in a country's grid and the cost of electricity.

I guess that Jay Weatherill is deeply regretting his cock up.

I prefer the economics drive power policy not subsidies or ideology. If an industry can exist on renewable energy then sure do so but right now its at a higher price that is coming down for solar at least.
Heavy industry its not so true they need scale of economy and a reliable energy source with redundancy that at least for SA does not exist. The focus on renewables has taken the focus away from good practice, closing power stations was just plain stupid and SA seems to have a poor grid design relying on Victoria ?
My view on that approach is why have an SA government at all if they are going to abdicate responsibility ? I don't want to start a debate on useless state government not being required but the SA government is a good reason to do so.

Surely it is economists who abdicate responsibility in the advice they don't provide involving the negatives such as cost and life of batteries essential for nighttime solar.

A couple of significant points:

BOM, and other Agencies are suggesting there is a likelihood on ENSO going back into an El Nino phase for 2017. Unusual circumstance as El Nino occurs cyclicly; not yearly, 2015 had been suggestive of an El Nino event could happen.

The other matter relates to APRA, watch the short video.

And quote:

"Australia's greenhouse gas pollution jumped in 2015-16 as coal use continued to rise after the scrapping of the carbon price, making it harder to meet its emissions targets.

Overall emissions are up 3.4 per cent compared with 2014-15 and up 7.5 per cent since the Abbott government eliminated the carbon price in June 2014, the Australian Conservation Foundation said, citing new data released under the National Greenhouse & Energy Reporting Scheme."

Coal being cheap might appear so on the surface, but, there are many hidden costs, health being one of them.

Further significant points:

Shell knew about the impacts of climate change in the 1990s:

Though

ExxonMobil scientists had already stated that fossil fuels have an impact on climate in the 1970s.

And

A New Zealand paper discussed the anticipated problems with fossil fuels in 1912.

Another matter:

Huge areas of permafrost thawing in North West Canada. Permafrost does not thaw unless temperature increases and remains in an increased period for some time.
