7 March 2017, The Conversation, Five-yearly environmental stocktake highlights the conflict between economy and nature. Australia’s population growth and economic activity continue to pose major environmental challenges, according to a comprehensive five-yearly stocktake of the country’s environmental health. The federal government’s State of the Environment 2016 report (prepared by a group of independent experts, which I chaired), released today, predicts that population growth and economic development will be the main drivers of environmental problems such as land-use change, habitat destruction, invasive species, and climate change. These main pressures are broadly the same as those listed in the first ever State of the Environment report in 1996. Yet since the last report in 2011, there have been some improvements in the state and trend of parts of the Australian environment. Our heritage (built, natural, and cultural) and marine environments are generally in good condition, as is the Australian Antarctic Territory. However, the Great Barrier Reef was affected significantly by Cyclone Yasi in 2011 and record high sea surface temperatures in 2015-16, resulting in extensive coral bleaching and die-off, particularly across the northern regions. Pressures and changes The new report shows that some individual pressures on the environment have eased since the 2011 report, such as those associated with air quality, poor agricultural practices and commercial offshore fishing, as well as oil and gas exploration and production in Australia’s marine environment. During the same time, however, other pressures have increased, including those associated with coal mining and the coal-seam gas industry, habitat fragmentation and degradation, invasive species, litter in our coastal and marine environments, and greater traffic volumes in our capital cities. Climate change is an increasingly important and pervasive pressure on all aspects of the Australian environment. It is altering the structure and function of natural ecosystems, and affecting heritage, economic activity and human well-being. Read More here

6 March 2017, Renew Economy, Fear and ignorance: Gas plant “explodes”, renewables blamed. It didn’t take long after the failure of South Australia’s two biggest gas plants late on Friday afternoon for the abuse to start flowing. “Renewables, absolute frigging BS,” wrote one correspondent in an email to RenewEconomy within a few hours of the sudden loss of 600MW of gas-fired generation. “What a lot of crap this renewable story is.” It happens all the time. + When a storm knocks down three power lines in September, the immediate reaction is to blame renewables; + when a condenser in Victoria hits the ground and takes out the main inter-connector, forcing rolling stoppages in South Australia, the immediate reaction is to blame renewables; + when more storms take down power lines after Christmas, causing more outages in South Australia, the blame is put on wind and solar; + and when the market operators turn out to be the only people in South Australia unaware of a pending heat wave, forcing them to miscalculate a demand surge and impose rolling stoppages, it was once again the fault of renewable energy. Friday’s events, however, took this blame game to a new level. Some sort of explosion occurred at the Torrens Island gas plant, starting fires and causing three units (totalling 400MW) to suddenly trip off and lose power, and causing the Pelican Point gas generator (210MW) to do the same…..Apparently, though, it’s all the fault of renewables, a conclusion drawn from the same twisted logic that supports the gun lobby in the US. As Don Russell wrote in The Monthly, guns killed 301,797 people in the US between 2005, and 2015 (and terrorists killed 95), but it wasn’t guns but restrictions on guns that was cited as being the fourth greatest fear in the US.

21 February 2017, The Conversation, Labor’s climate policy could remove the need for renewable energy targets. The federal Labor Party has sought to simplify its climate change policy. Any suggestion of expanding the Renewable Energy Target has been dropped. But there is debate over whether the new policy is actually any more straightforward as a result. One thing Labor did confirm is its support for an emissions intensity scheme (EIS) as its central climate change policy for the electricity sector. This adds clarity to the position the party took to the 2016 election and could conceivably remove the need for a prescribed renewable energy target anyway. An EIS effectively gives electricity generators a limit on how much carbon dioxide they can emit for each unit of electricity they produce. Power stations that exceed the baseline have to buy permits for the extra CO₂ they emit. Power stations with emissions intensities below the baseline create permits that they can sell. An EIS increases the cost of producing electricity from emissions-intensive sources such as coal generation, while reducing the relative cost of less polluting energy sources such as renewables. The theory is that this cost differential will help to drive a switch from high-emission to low-emission sources of electricity. The pros and cons of an EIS, compared with other forms of carbon pricing, have been debated for years. But two things are clear. Read More here
20 February 2017, The Guardian, Turnbull says own rooftop solar not inconsistent with ‘clean-coal’ message. Malcolm Turnbull has hit back at suggestions that his house’s large personal rooftop solar and battery system sends a message contrary to the government’s endorsement of “clean coal”. He rejected the idea that he had ever been critical of the renewables sector and dismissed his treasurer’s brandishing of a lump of coal in question time as “theatrics”. “It’s not a question of beliefs, saying ‘Do you believe in renewables?’,” the prime minister said. “It’s like saying ‘Do you believe in tables?’ Renewables are there, they are doing well, they have got certain characteristics and you have to design your grid to take account of that.” As his energy and environment minister, Josh Frydenberg, raised the prospect of changing the mandate of the Clean Energy Finance Corporation to accommodate coal, the prime minister said he had always been objective about energy. Asked whether his solar panels were enough to provide power to three average homes, Turnbull agreed that his personal 14.5kW system on the roof of his Point Piper home, with battery storage, was a “large array”. Turnbull went on to explain his position on climate change and his government’s energy policy. “I believe that climate change is a threat that we have to deal with,” Turnbull told ABC Perth. “I believe that we have to reduce our emissions. I believe that we need to ensure that we use all technologies to generate energy.” Read More here
