SA green energy crisis

South Australia has rightly been acclaimed as a leader in renewable energy. Already 38% of their electricity comes from wind and solar. Yet

    Futures contracts on the ASX Energy market for electricity delivered in 2016-2018 are between $86 and $90 a MWh in South Australia, compared with between just $37 and $41 MWh in Victoria and between $43 and $48 MWh in NSW.

What’s going on? Continue reading SA green energy crisis

1. Game changing steel to make lighter cars etc.

From Gizmag, courtesy of John D:

    Back in 2011, we wrote about a fascinating new way to heat-treat regular, cheap steel to endow it with an almost miraculous blend of characteristics. Radically cheaper, quicker and less energy-intensive to produce, Flash Bainite is stronger than titanium by weight, and ductile enough to be pressed into shape while cold without thinning or cracking. It’s now being tested by three of the world’s five largest car manufacturers, Continue reading Climate clippings 160

Queensland’s energy revolution

The Palaszczuk government in Queensland came into power with a policy for 50 per cent renewable energy by 2030. Giles Parkinson says:

    The state of Queensland appears ready to embark on what could be one of the most radical transformations of its electricity network ever undertaken – even by standards of ambitious mandates in places such as California, Germany and Denmark.

Plans include solar, wind, pumped storage, bioenergy and an enhanced research capacity. Continue reading Queensland’s energy revolution

1. Greg Hunt the worst environment minister ever

I’ve just discovered this one from August, where Ben Eltham unloads on Greg Hunt, calling him our first minister for pollution:

    There are no kind words that can be said about Greg Hunt. When it comes to protecting the environment he is useless, and actually seems to revel in eviscerating the portfolio he is responsible for. Continue reading Climate clippings 159

Paris climate talks at a tipping point

Negotiators at the Paris climate talks have done well to produce a complete text of some 48 pages. It was around 100 at the beginning of the year. The only problem is that they have essentially decided nothing in the first week of the talks. Disputed or unresolved text is bracketed and there are 939 sets of brackets for the ministers, who have now arrived, to deal with. At least it’s clear where the problems lie. The Saudis continue to obstruct; the Indians are playing a “blocking role”. Continue reading Paris climate talks at a tipping point

Talking climate in Paris

As our leader flew into town to give a 2.5 minute speech at the Paris climate talks, and Le Monde still branded Australia a climate “dunce”, the French lit up the Eiffel Tower with 3D pictures of forests, and protesters clashed violently with police, Sara Phillips said “the vibe is the thing”.

Sentiment has changed markedly in recent years, she says. Continue reading Talking climate in Paris

1. Growing corals turn water more acidic

Scientists carefully monitored a coral reef in Bermuda for five years and what they found surprised them. According to the New Scientist, they

    discovered that the coral growth itself drove up this local acidity. To build their skeletons, it seems the corals sucked alkaline carbonate out of the water, leaving it more acidic.

Adani’s Carmichael coal mine faces new legal challenge

The Australian Conservation Foundation has initiated a new legal challenge to Adani’s huge Carmichael coal mine proposal.

In what it has called a “historic, landmark case”, the ACF argues that Federal Environment Minister Greg Hunt failed to consider whether the impact of burning coal and climate pollution would be inconsistent with Australia’s international obligations to protect the Great Barrier Reef. Continue reading Adani’s Carmichael coal mine faces new legal challenge

1. Obama rejects the Keystone pipeline

Obama has rejected the proposal to build a pipeline to bring tar sands oil south from Canada to refineries in the Gulf Coast.

    Obama said Friday that the State Department, in its final Environmental Impact Statement, found that the pipeline would not be in the country’s national interest. “I agree with that decision,” he said.
