If it was designed with a focus on reliability, security and the lowest cost for consumers, Australia’s main electricity grid would see periods in which nearly 90% of demand is met by renewable generation. A diverse portfolio of distributed energy resources and large-scale solar and wind generation supported mainly by pumped hydro and batteries would ensure the least-cost transition as the nation’s coal plants retire. Adequate investment in transmission infrastructure will be instrumental in making this a reality.

Scientists in India have taken a close look at the potential impact of growing volumes of PV waste, and have conducted surveys that suggest a lot more work is needed from manufacturers and policymakers to develop management systems for end-of-life PV products.

A team of international researchers featuring ANU’s Prof Frank Jotzo has published a study on the ‘just transition’ from coal to renewable sources of energy. The paper looks at comparative examples of transitioning economies, taking account of political realities, and ultimately shows that a ‘just transition’ is just about the only transition worth having.

New system strength challenges have been identified in North Queensland putting the output of nearly 800 MW of additional solar projects at risk.

The Western Australian Government’s $5.5 billion WA Recovery Plan was released yesterday, the plan features $66.3 million in renewable energy investment, most of that to go on solar and batteries, along with a significant top up of the Clean Energy Future Fund.

Thanks to the Covid-19 many of us find ourselves in lockdown with little reprieve other than a morning potter or an evening stroll. In Goulburn, thanks to what is being called Australia’s largest solar lighting installation, locals can now more easily walk and cycle their way to the salutary effects of a daily jaunt.

The Australian renewables sector was not immune to a host of challenges that marked the first half of the year, but the pipeline of renewable energy projects in the country reached new heights. While new construction dipped to a four-year low and financial close remained out of reach for a great number of projects, the second half of the year is looking more positive, according to Norwegian consultancy Rystad Energy.

Researchers at Monash University will conduct a desktop study to explore issues and strategies associated with connecting inverter-based generation such as batteries, solar, and wind into weaker parts of the National Electricity Market.

In a world-first, scientists in Australia and the United States have managed to upconvert light from below the silicon bandgap with the help of oxygen into high energy light that can be captured by silicon solar cells.

The Chinese manufacturer has claimed a world record for a large-size, contact-passivated solar cell. The result, certified by Germany’s Institute for Solar Energy Research in Hamelin, betters the company’s previous record by almost 0.6%.
