- 1Data centre boom puts Alberta's water and power under strain●An environmental reckoning? Data centre rush hits hard realities # Alberta # Canada # Tech # AI # Water # DataCentres #
Alberta is facing hard questions over its rapid data centre expansion, as the surge of facilities built to serve artificial intelligence puts pressure on the province's water supplies, electricity grid and natural gas resources. Commenters are weighing the economic promise of the tech influx against its environmental cost, including impacts on rural communities, utilities and climate goals, asking whether the boom amounts to an environmental reckoning for Canada.
- 2Australia's main grid runs on 80% renewables for consecutive days▼Australia's main grid hits 80% renewables on consecutive days, rooftop solar tops half of demand
Australia's main electricity grid has recorded 80% renewable energy across consecutive days, with rooftop solar at times supplying more than half of total demand. The milestone highlights the rapid growth of household solar and wind capacity in the country, with observers pointing to it as evidence that a heavily renewable grid can reliably meet everyday power needs.
- 3Solar 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, according to a report shared widely online. The milestone highlights the country's rapid shift from coal and gas toward solar and wind, reinforcing Australia's position as one of the world's faster energy transition stories and prompting discussion about grid reliability and the pace of decarbonisation.
- 4AI Chips Get More Efficient as Data Center Power Demand Soars▼AI Chips Are 10× More Efficient. Data Center Power Demand Keeps Exploding
New analysis highlights a paradox in the AI boom: even as AI chips become roughly ten times more energy efficient, overall power demand from data centers continues to climb. Gains in per-chip efficiency are being outpaced by the sheer scale of AI deployment, as operators race to build capacity for training and serving large models. The piece has reignited debate over whether efficiency improvements can ever curb the industry's growing energy footprint.
- 5Solar Storms Pose Growing Threat to Power Grids●Disasters from the Sun: Threats to Power-grids and Digital Infrastructure
Analysts are warning that solar storms and other space weather events could inflict serious damage on electricity grids and digital infrastructure worldwide. A powerful solar flare or coronal mass ejection could knock out transformers, communications and satellite systems, with the ORF analysis arguing that governments have underprepared for this natural hazard despite growing dependence on interconnected power and digital networks.
- 6Sun King Lands $5 Million Acumen Investment to Expand Solar Access in Zambia●Sun King Secures USD 5 M Acumen Investment To Expand Solar Access In Zambia
Off-grid solar company Sun King has secured a USD 5 million investment from Acumen to expand access to solar energy in Zambia. The funding is aimed at growing the company's pay-as-you-go solar products among households with limited or unreliable access to electricity. The move highlights continued investor interest in African off-grid energy startups working to close the continent's power access gap.
- 7Ukraine expects no power outages on Monday●Ukrenergo forecasts no power outages on Monday No restrictions on electricity consumption are planned in Ukraine on Mond
Ukraine's national grid operator Ukrenergo says no restrictions on electricity consumption are planned for Monday, September 28, meaning households and businesses should face no scheduled power outages. The announcement is being shared across Ukrainian news feeds, with readers watching grid updates closely as the country continues to manage electricity supply under wartime conditions.
- 8Trump's home county pauses data centers over power concerns●Trump's home county hits pause on data centers over environment and electric bill concerns
Officials in Palm Beach County, Florida, Donald Trump's home county, have imposed a pause on new data center development, citing environmental impacts and worries about rising electricity costs for residents. The decision reflects a broader national debate over the rapid expansion of data centers fueled by artificial intelligence, which are straining local power grids and driving up utility bills in communities hosting them.
- 9California homeowner gets first negative PG&E bill with battery exports●California homeowner on NEM 3.0 gets first negative PG&E bill, thanks to August battery exports
A California homeowner on the state's NEM 3.0 solar billing scheme has received their first negative PG&E bill, with excess electricity exported from a home battery in August more than covering their usage charges. It is being cited as an example of how battery storage can offset the steep export-rate cuts introduced under NEM 3.0, which slashed payments for rooftop solar power sent to the grid.
