The past three years have been the world’s hottest on record. In 2025, Earth was 1.44°C warmer than the long-term average, perilously close to breaching the Paris Agreement goal of 1.5°C.

Around a fifth of solar panels examined in a new study fail much faster than expected and some may last for only half their anticipated lifetime.

There was a watershed moment for Australian energy transition this week as the Australian Energy Market Operator released its energy dynamics report for the December quarter of 2025: Renewables comprised more than half of energy supply in the quarter, driving down wholesale electricity prices by nearly half. Coal-fired generation was down 4.6% year on year, falling to an all-time quarterly low. Gas-fired generation plunged 27% to its lowest level for 25 years.

For the last decade, the global conversation around electric vehicles (EVs) has focused almost entirely on adoption. Targets, incentives, charging stations and sales figures have dominated headlines. The EV transition is happening daily, at street level, across the Asia-Pacific region and beyond. Yet a far less glamorous question is now becoming just as important as how many EVs we sell: what happens when their batteries are no longer good enough for the road?

Solar and wind now provide 99% of new generating capacity in Australia. Renewables supply more than 40% of power to the main grid. Australia will need six times as much solar and wind to reach net zero through the electrification of everything. This means building new transmission corridors, as existing lines were built to connect cities with coal power stations. But the best solar and wind resources lie in different places.

Plans for a 250 MW solar and 350 MWh battery energy storage project proposed for Queensland’s Western Downs region are now available for public comment as developer Pacific Partnerships seeks a green tick from the federal government.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

Battery energy storage went from strength to strength across Australia in Q4 2025, seeing the technology outperform past records in both the National Electricity Market and Western Australia’s Wholesale Electricity Market.
