- 1Renewables reshape energy security after global crisis●From energy crisis to energy transition: How renewables are reshaping energy security
UN News examines how the recent global energy crisis has accelerated the shift toward renewable energy, arguing that solar, wind and other clean sources are redefining what energy security means for countries worldwide. The piece frames the transition away from fossil fuels as both a climate necessity and a strategic move to reduce dependence on volatile fuel supplies.
- 2Coal still supplies a third of world electricity in 2024●Where does the world's electricity come from? In 2024, coal still produced about a third of it (34%), while wind and sol
New figures on the global electricity mix show coal remained the largest single source in 2024, producing about 34% of the world's power. Wind and solar together reached 15%, a sharp rise from just 4% a decade earlier, prompting discussion about the pace of the energy transition.
- 3Measuring grid inertia as renewables replace traditional power plants▼How do you measure grid stability as we shift to renewables? Solar/wind lack the natural inertia of traditional power pl
As solar and wind replace conventional power plants, grids lose the natural inertia that traditionally stabilised electricity systems. UK-based Reactive Technologies is addressing this by sending sonar-like pulses through power networks to measure live grid inertia directly, uncovering stability risks that existing models miss. The company has received €19 million in backing from the European Investment Bank to develop the technology further.
- 4Distributed renewables help Ukraine withstand Russian attacks▼In Ukraine, distributed renewables foil Russia’s assaults
Ukraine's spread-out renewable energy installations are proving resilient against Russian strikes on the country's power grid. Because solar and wind capacity is distributed across many sites rather than concentrated in large plants, attacks cause less disruption to electricity supplies, supporting the country's energy security during the war.
- 5Solar and wind hit record 80% of Australia's grid demand●"Solar and wind generation meet record 80% of power demand on Australia’s national grid" # Australia # Energy # Renewabl
Solar and wind generation supplied a record 80% of power demand on Australia's national electricity grid, according to a report by The Guardian. The milestone marks a new high for renewable penetration on the network and highlights the pace of Australia's shift away from coal and gas. Commenters online are sharing the figure as evidence that renewables can cover the bulk of demand, with debate continuing over grid stability and backup capacity.
- 6Fossil Fuel Industry Accused of Shifting Goalposts on Renewables●The Fossil Fuel Industry Keeps Shifting the Goalposts How denial tactics have evolved as renewable energy succeeds... Th
Commentators are revisiting how fossil fuel industry denial tactics have evolved as renewable energy outperforms past predictions. The discussion highlights Barnaby Joyce's 2013 claim in an Australian Senate debate that a 5% solar target was "never going to happen" — a target solar has since far exceeded. Critics argue opponents of renewables repeatedly move the goalposts once old arguments are disproven, and the pattern is being cited as solar and wind expand worldwide.
- 7EGCO completes purchase of 49% stake in US renewables portfolio●EGCO closes buy of 49% stake in 339-MW US solar, wind portfolio
Thai power company Electricity Generating (EGCO) has closed its acquisition of a 49% stake in a 339-megawatt portfolio of solar and wind plants in the United States. The deal adds renewable generation capacity to the company's overseas portfolio and reflects its strategy of expanding into clean energy assets abroad, according to the announcement of the completed purchase.
- 8JP Energie announces 202 MW of wind and solar acquisitions●France’s JP Energie announces 202 MW of wind, solar acquisitions
French renewable energy developer JP Energie has announced acquisitions totalling 202 MW of wind and solar capacity. The move expands the company's portfolio in France's fast-growing renewables market. Details on the specific projects, sellers and financial terms were not disclosed in the announcement, which was reported by trade outlet Renewables Now.
- 9University of Iowa researcher wins funding for solar wind plasma wave detection▼UI researcher earns funding to improve detection of plasma waves in the solar wind
A University of Iowa researcher has received new funding to develop better methods for detecting plasma waves in the solar wind, the stream of charged particles flowing from the Sun. The work, announced by the university's news service, could improve understanding of space weather and its effects on satellites and communications systems on Earth.
- 10Penn State to host talk on AI and climate impacts on renewables▼Oct. 2 talk to discuss AI insight for climate change impacts on renewable energy
Pennsylvania State University is hosting a talk on October 2 examining how artificial intelligence can offer insights into climate change impacts on renewable energy. The event will bring together researchers to discuss how AI tools can help predict and manage climate-related challenges facing solar, wind and other renewable power sources.
