Key developments
Study finds summers growing longer worldwide
A study in Environmental Research Letters examined temperature thresholds in 10 global cities and found summer length is increasing by about six days per decade on average. Sydney is lengthening fastest in the sample, with summer extending about 15 days per decade and shifting from roughly Jan. 6-Mar. 9 in 1961-70 to Nov. 27-Mar. 28 in 2014-23. Researchers said the change has implications for school terms, fire seasons, crop timing, and heat-health planning.
Why it matters
It quantifies how climate change is already altering seasonal timing, not just average temperatures.

THE GUARDIAN
The Guardian coverageGeorgia Power approves customer clean-resource plan
Georgia regulators unanimously approved Georgia Power's Customer Identified Resource program, allowing large customers to finance eligible clean projects and receive renewable energy certificates and energy credit. The framework is designed to support up to 3 GW of customer-identified resources through 2035 and can include projects sited outside Georgia if power delivery is feasible under the interconnection rules. The approval comes alongside Georgia Power's broader plan to procure 4 GW of new renewables over the same period.
Why it matters
It opens a new path for large-load customers to bring clean resources online, though the emissions impact will depend on siting and REC accounting.

Utility Dive coverageSuniva commits $350 million to South Carolina
Reuters reported that Suniva will invest $350 million in a solar-cell factory in Laurens County, South Carolina. Production is planned to start in early 2027, with the plant expected to open in the second quarter of 2027 and capacity rising from 1 GW to 5.5 GW once fully operational. The company said more than 550 jobs are expected and linked the expansion to stronger U.S. demand and policy changes affecting access to federal clean-energy tax credits.
Why it matters
It signals continued U.S. solar manufacturing expansion and a supply-chain shift shaped by policy.

Cold mortality dwarfs heat
A new U.S. study estimated about 42,735 heart-disease deaths a year linked to cold exposure versus about 2,242 cardiovascular deaths a year linked to heat, suggesting temperature risk is undercounted.

Britain shifts demand to renewables
The UK grid operator is pushing households and businesses to run appliances and charge EVs when wind and solar output is abundant, a notable grid-flexibility tactic.

Vermont geothermal project nears groundbreak
Riggs Meadow is set to become Vermont's first neighborhood-scale geothermal project, but frozen federal grant funding forced a simplified design.
Still unclear
OPEN QUESTION
Will Georgia Power's program add real clean capacity?
Because the framework relies on customer-funded projects and renewable-energy credits, its actual emissions impact is still uncertain.
OPEN QUESTION
How far do the longer-summer findings extend?
The study used aggregated data from only 10 cities, so local validation could reveal sharper or weaker seasonal shifts.
