- 1Solar and wind hit record 80% of Australia's power demand●"Solar and wind generation meet record 80% of power demand on Australia’s national grid" # Australia # Energy # Renewabl
Renewable sources supplied a record 80% of electricity demand on Australia's national grid, with solar and wind generation combining to reach the milestone. The result is being cited as evidence that renewables can carry a large share of a major advanced economy's power system, adding to ongoing debate in Australia about the pace of the energy transition and the future role of coal and gas.

New research reported by Science News suggests that magnetic fields may have played a key role in the formation of the solar system, potentially helping to trigger the collapse of the gas cloud that ultimately formed the sun and planets. The finding adds to debate over what set off the processes that shaped our cosmic neighbourhood billions of years ago.
- 3ESA's JUICE spacecraft sweeps low over the Indian Ocean●Heads up (especially if you’re currently on a ship in the Indian Ocean). ESA’s JUICE mission to Jupiter & its icy moons
ESA's JUICE mission to Jupiter and its icy moons is performing its second Earth gravity assist, passing less than 10,000 km overhead at 13:45 CEST, directly above the Indian Ocean. The flyby uses Earth's gravity to adjust the spacecraft's trajectory toward Jupiter. A final Earth slingshot is planned for 2029 before JUICE continues to the outer solar system.
- 4Study finds utility-scale solar lowers grid costs●Our study didn’t ignore grid costs. We measured them — and utility-scale solar lowers them.
Researchers have pushed back against claims that their work overlooked grid expenses, saying the analysis directly measured them and found that large-scale solar power reduces overall system costs. The findings, published via Commonwealth Beacon, argue utility-scale solar delivers savings for electricity customers rather than added burdens, in a contribution to ongoing debates over renewable energy economics.
- 5Pittsburgh green advocates launch solar panel group buy●Green advocates organize group buy of solar panels for Pittsburghers to save on energy bills
Green advocates in Pittsburgh have organized a group purchasing program for solar panels, allowing residents to buy systems together at a discounted rate to cut their energy bills. The initiative aims to make renewable energy more affordable for households across the city by pooling demand to negotiate lower installation prices.
