From an energy-hungry importer to a frontrunner in the decarbonization race, South Australia has set the bar high for how to efficiently transition to a low-emissions grid dominated by renewables. With wind and solar already supplying more than a half of its electricity, the state’s energy transition shows no sign of letting up. In fact, South Australia is gearing up to accelerate the pace of its clean energy transition and expand its big PV fleet as it moves toward its 2030 target of “net” 100% renewables.

No man is an island, but solar PV can at least allow us to live on one without having to rely on the expensive logistical nightmare of diesel fuel supply. More islands around the Asia Pacific are turning to solar PV systems combined with storage to meet their needs.

The South Korean capital has unveiled a plan to deploy rooftop PV on a million homes and all public buildings. The new initiative is designed to bring the city’s cumulative installed solar capacity to around 1 GW by the end of 2022.

Swiss investment firm SUSI Partners is investing up to $50 million in a residential solar-plus-battery project enabling participants from communities across Western Australia to generate and consume their own clean power for up to 90% of their needs. The project, which began a year ago, and involves residents leasing solar PV and battery systems from a not-for-profit organisation.

Spanish renewables giant Iberdrola expands its reach into Australia with a planned 650 MW pipeline of projects just as it also pledges to “relaunch clean energies in Spain”.

Abundant sunshine, favorable policy settings and high power prices have long placed Australia at the cutting edge of rooftop solar uptake. The more recent utility-scale boom has further enhanced its status as a PV leader. Battery adoption, microgrids, EVs and green hydrogen are all taking shape, yet what should be an Aussie smart energy no-brainer continues to be dogged by mounting investment uncertainty and a toxic debate on the national level.

A number of massive PV projects have been proposed for Australia’s north, with the concept built around clean power exports to Southeast Asia. Is it Desertec Down Under? Proponents are certainly hoping for more success.

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

In a deal that can only improve the appeal of renewable energy to the mining industry, Siemens and renewable energy developer juwi have joined forces in a strategic technology partnership set to bring renewable microgrids to the off-grid mine sites.

New research by the World Gold Council identifies greenhouse gas emissions across the whole supply chain of gold mining and sets out a plan to aureate the industry’s carbon footprint with solar PV and other renewables.
