9 June 2015, Renew Economy, How South Australia coped without any baseload power: South Australia’s electricity system was put the test over the long weekend when the state’s only baseload power contributor, the brown coal Northern power station near Augusta, suddenly tripped and stopped providing power. The incident was caused by a fire that caused several injuries, including one serious injury to a worker still in hospital. This is not the first time that South Australia has been without baseload coal power, of course. Northern was mothballed for nearly a year because of the declining economics of the coal generator. The difference with this event is that it came unannounced. While declines and increases in the output of wind and solar are quite predictable, sudden outages in baseload fossil fuels are not, which is why the energy system needs a large amount of redundancy to support large centralised generation.

9 June 2015, Science Daily, Land management practices to become important as biofuels use grows: The handling of agricultural crop residues appears to have a large impact on soil’s ability to retain carbon, making land management practices increasingly important, especially under a scenario where cellulosic materials become more heavily used as a feedstock for ethanol production, according to a recently published study led by researchers at the U.S. Department of Energy’s Argonne National Laboratory. “Plants and soil are carbon sinks,” said Argonne climate scientist Beth Drewniak, who led the study. “Soils lock carbon away for long periods of time. But when plant residues are harvested, not only are inputs of carbon and other nutrients to soil lost, but decomposition is accelerated, causing soils to lose additional carbon.” Read More here
r ageing populations could help slow greenhouse emissions: finally -something good about being a Baby Boomer! In many parts of the world, and particularly in developed countries, populations are getting older. Of the baby boomers (born between 1945 and 1965), the oldest are now well into their sixties, and in their lifetimes fertility rates have fallen while life expectancies have climbed… Population ageing will put significant pressure on the fiscal policies of governments around the world. Healthcare and pension systems are expected to bear the brunt, while ageing populations will shrink the labour force, putting downward pressure on economic productivity. But what if there’s an upside for the environment? My recent research has found that, in rich countries at least, ageing populations might help to drive down greenhouse gas emissions. Read More here
9 June 2015, Renew Economy. Pressure on Abbott’s coal strategy as G7 signals end of fossil fuels: Less than a month after the Abbott government committed billions of dollars in funding to prop up Australia’s coal industry, the world’s major G7 democracies have set a deadline for weaning their economies off carbon intensive fuel sources like coal, oil and gas – and to help developing countries do the same – offering one of the clearest signals yet that the age of fossil fuels is coming to an end. At the close of the weekend Summit in Germany, the leaders of the Group of Seven nations – Canada, France, Germany, Italy, Japan, the UK and the US – pledged in a communique to develop long-term strategies to combat climate change, including abandoning fossil fuels by the end of the century.
