18 October 2017, The Conversation, Federal government unveils ‘National Energy Guarantee’ – experts react. The federal government has announced a new energy policy, after deciding against adopting the Clean Energy Target recommended by chief scientist Alan Finkel. The new plan, called the National Energy Guarantee, will require electricity retailers to make a certain amount of “dispatchable” power available at all times, and also to reduce the electricity sector’s greenhouse emissions by 26% relative to 2005 levels by 2030. The government says it will save the average household up to A$115 a year after 2020, while also ensuring reliability. Below, our experts react to the new policy.Read more: Infographic: the National Energy Guarantee at a glance. Read More here

2 October 2017, Australian Institute, We have enough cheap, easy-to-extract gas to last 100 years. There’s just one problem. Australia has plenty of cheap gas. The problem is private companies are selling it all overseas, writes principal adviser at the Australia Institute Mark Ogge. Hard to believe, isn’t it? But it’s true: in the last decade, tens of thousands of square kilometers of Queensland farmland has been covered in gas fields. The export gas rush in Australia is one of the largest and fastest expansions of a gas industry ever seen, anywhere in the world. We are awash with gas. The problem is we are allowing almost all of the cheap and easy-to-get-at gas to be sent overseas. The gas in some areas is close to the surface, in big reserves all together, where there are no bothersome farmers, aquifers or national parks in the way. That gas is relatively cheap to extract. But some gas is deeper and harder to get at for all sorts of geological reasons. And that gas is more expensive to extract. Some gas is not just deep and hard to get at, but is underneath valuable aquifers that would need to be drilled through to get the gas. Much of it is on properties of people who don’t want a gas field on their land, or on properties a long way from where the gas is needed. That gas is very expensive to extract. So, naturally, the gas companies’ first preference is for the easily extractable, cheap gas, and they drill that and sell it first. The problem is, there is a limited amount of that cheaper to extract gas. Once that gas is gone, only the difficult, expensive-to-extract gas remains. That was OK when it was just being sold to Australian customers. There was enough reasonably easily extractable, cheap gas to last for decades at least. Read More here

29 September 2017, Carbon Brief, Analysis: What does revised methane data mean for the Paris Agreement? A study released today finds that global methane emissions from agriculture are much larger than previous estimates have suggested. Revised calculations find that methane emissions from livestock in 2011 were 11% higher than modelled estimates based on data produced in 2006 by the Intergovernmental Panel for Climate Change (IPCC). In response, media outlets including the BBC Radio 4 Today programme and Agence France-Presse (AFP) released reports suggesting that the findings could mean that it will be harder for countries to meet the goals of the 2015 Paris Agreement. Carbon Brief spoke to the authors of the new study, as well as scientists from the Priestley International Centre for Climate at the University of Leeds, and asked them to analyse these claims. What did the new study find? Methane is a potent greenhouse gas and the second biggest contributor to human-caused global warming after carbon dioxide. Livestock produce large amounts of methane as part of their normal digestive process, largely through passing wind. Also, when the animal manure is stored or managed in lagoons or holding tanks, more methane is released into the atmosphere. The extent to which methane emissions from agriculture could contribute to future global warming has been examined by international scientific bodies including the Intergovernmental Panel on Climate Change (IPCC) and the US Environmental Protection Agency (EPA).

12 September 2017, Renew Economy,AEMO: Our advice was pretty straight forward, we need dispatchability. As the federal Coalition continues to push the case for an ageing, unreliable, and slow moving coal generator to maintain energy security in the 2020s, the Australian Energy Market Operator has underlined its advice to the government last week: it wasn’t a push for more baseload. “We need flexible capacity that can be switched on and off, and we need to transition to a new generation of Australia’s principal energy market institutions, and the newly-formed Energy Security Board. “Our advice was fairly pragmatic,” Zibelman said. “We are concerned that on a 45°C day if we lose a generator (which AEMO has said is quite likely) we want reserves in the system to be able to respond. “In our report we identified the fact that with amount of variability (from solar and wind energy and electricity usage) is changing rapidly, we need resources that can change rapidly. “That may be different to traditional baseload resources, which do not move a lot.  It doesn’t mean baseload is bad, it’s just that we need a different portfolio. (Baseload) may not be able respond in the time period we need it to respond.” Sound like Liddell? Not really. The plant owner AGL Energy has made it clear that Liddell is old, increasingly unreliable, expensive to maintain, prone to unexpected outages and can’t be relied upon at times of peak demand, particularly as temperatures rise. Zibelman’s comments, like the two AEMO reports it released last week, contrast starkly with the Coalition government’s contention that AEMO had insisted  that rapid action was needed, and that that rapid action must mean that Liddell’s life span must be extended. Zibelman made it absolutely clear that her preference was for fast, flexible technologies, both in supply and demand, and bother in front and behind the meter. Importantly, it had to be technology that the market operator could rely upon. Read More here
