Seaweed excites this marine scientist – even though it nearly killed her
On a summer’s morning in 2019, in the small New South Wales farming community of Bolong, on the Shoalhaven River, Dr Pia Winberg walked into the processing plant from which she was building her budding seaweed business. Winberg had overnight left a tank of liquid to filter. It contained an extract of a native species […]
Australia’s environmental scorecard: how are we performing? And whose job is it anyway?
As the climate catastrophe morphs from looming threat to ever-present reality, our relationship with it is changing. Australians in particular are watching its effects play out in record-breaking natural disasters, from fires to floods. It’s clear by now that our actions have consequences. Those consequences are being felt around the globe, often in those regions that are most vulnerable to extremes […]
“So smooth:” Students test drive solar car they spent three years designing
On a soaking wet spring day at Deakin University’s Waurn Ponds campus in Victoria, under a leaden sky devoid of sunshine, two former engineering students are finally taking the solar-powered car they have painstakingly designed over three long years for a spin. “It’s so smooth,” enthuses Angus McDonald, one of the two key designers among […]
Woodside nearly doubles revenue as fossil fuel giants cash in on oil and gas prices
Woodside Energy’s quarterly revenue has nearly doubled in a year thanks to strong gas pricing, following a similar announcement from oil and gas giant Santos last week. Woodside on Wednesday reported an 81% jump in its fourth-quarter revenue despite recent declines in oil prices. The company’s high performance is likely down to the fact that most of Woodside’s LNG […]
Environmental groups warn WA’s gas projects will derail new net-zero legislation
Western Australia is to enshrine its commitment to net zero emissions by 2050 into law, but environmental groups warn that the state’s proposed gas projects could derail the goal before it gets off the ground. The announcement, made today by Climate Action Minister Reece Whitby, includes a provision requiring Whitby and his ministerial successors to […]
Six ways Aussie researchers hope to deliver ultra low-cost solar
UNSW Sydney projects have been awarded a glut of funding by the Australian Renewable Energy Agency (ARENA) to support research and development that will significantly reduce the cost of solar. As reported this week, the funding is part of ARENA’s ‘Solar 30 30 30’ target, aimed at achieving 30% module efficiency and 30 cents-per-installed-watt at […]
Truss lifts ban on fracking, and will prop up fossil fuel companies in energy crisis
