Len, since there seems to be no end to the hype coming out of South Australia these days, let's take a look at why little about SA is applicable to anywhere else in the world:
 

1. Except for coastal areas, SA is a desert (less than 5 in. rainfall/yr) with winds that blow all day long. Sun and wind like nowhere else on Earth.
2. The state has a total population of 1.7 million. That's two one-hundredths of one percent of global inhabitants.
3. The average residential price of electricity is 27¢/kWh (US) - thirteenth highest in the world.
4. Australia is #2 in the world in per-capita wealth (first is Luxembourg).
5. Much of that wealth is derived from exports of coal ($53B/yr ).

"In a world racing to reduce pollution, Australia is a stark outlier.

It is one of the dirtiest countries per head of population and a massive global supplier of fossil fuels. Unusually for a rich nation, it also still burns coal for most of its electricity.

Australia's 2030 emissions target - a 26% cut on 2005 levels - is half the US and UK benchmarks.
 

Canberra has also resisted joining the two-thirds of countries who have pledged net zero emissions by 2050. And instead of phasing out coal - the worst fossil fuel - it's committed to digging for more. So it's no surprise that Australia is being viewed as a "bad guy" going into the COP26 global climate talks in Glasgow, analysts say."

Why Australia refuses to give up coal

SA is not an example. It's a state where residents, enriched by sales of coal, seek redemption for their environmental crimes by building an expensive, boutique electricity grid.
