Brazil has reached a new renewable energy record: in August, wind and solar together generated more than one-third of the country’s electricity. Government data analyzed by the think tank Ember showed that these two sources provided about 34% of total supply, delivering nearly 19 terawatt-hours—enough to power millions of homes. This shift represents a big jump from 2024, when they made up only 24% of electricity generation, according to AP News.
Diversified power mix reduces risks
For decades, Brazil has depended on hydropower, which still supplies more than half the country’s electricity. But hydropower is increasingly vulnerable to drought, a problem intensified by climate change. In August, hydro output dropped to its lowest in four years, yet Brazil avoided blackouts thanks to wind and solar. Fossil fuels provided just 14% of electricity, helping limit carbon emissions. The International Energy Agency notes that such diversification makes grids more resilient and less dependent on single resources.
Rapid growth and positive ripple effects
Brazil’s expansion of solar energy is particularly striking. In 2019, solar made up just over 1% of electricity generation; by 2024 it was nearly 10%. Wind also grew from about 9% to 15% in the same period. These investments are paying off: emissions from Brazil’s power sector have fallen by about 31% since 2014, even as electricity demand has risen by 22%. The World Bank highlights Brazil as a leader in showing how renewable growth can support economic development while cutting emissions.
The transition is also boosting jobs and innovation. Solar and wind projects are creating thousands of local positions, particularly in rural areas. The International Renewable Energy Agency estimates that Brazil now ranks among the world’s top employers in renewable energy, further embedding the sector into its long-term development model.
Why this matters
Brazil’s milestone demonstrates that even large, energy-hungry economies can power growth with clean sources. It also shows how countries vulnerable to climate impacts can build resilience by diversifying their energy mix. Perhaps most importantly, Brazil is currently the only G20 nation on track to meet the renewable targets set at COP28.
While challenges remain—such as managing grid stability and ensuring fair pricing—the overall trajectory is clear. Brazil’s success story is not just about technology, but about political will, community support, and sustained investment. As other nations watch closely, Brazil provides evidence that clean energy can scale quickly and reliably, lowering the extinction-level risks posed by climate change and offering a model for a more sustainable world.

Historic U.N. High Seas Treaty enters into force, launching a new era of global ocean governance
A new era for marine conservation has begun as the UN-brokered High Seas Treaty officially enters into force. Following ratification by 60 nations, this landmark agreement creates the first legal framework to protect biodiversity in the two-thirds of the ocean that lies beyond national jurisdiction. By empowering the creation of large-scale Marine Protected Areas, the treaty provides a crucial mechanism to safeguard vulnerable species like whales, sharks, and deep-sea corals from unregulated exploitation, ensuring the long-term resilience of the global ocean ecosystem.

New Jersey becomes latest U.S. state to ban student phones in schools
Governor Phil Murphy has signed a “bell-to-bell” cellphone ban for all New Jersey public schools, joining a growing list of states like Florida and Indiana in restricting device use. The law, effective for the 2026-2027 school year, requires phones to be stored away throughout the entire school day to improve student focus and mental health. This comprehensive policy reflects a rising bipartisan consensus across the U.S. that removing digital distractions is essential for restoring a healthy, engaging educational environment.

Guatemala launches historic rewilding of oil fields to protect the Maya Forest
Guatemala has launched a historic rewilding initiative by permanently closing the Xan oil field inside Laguna del Tigre National Park. This decision protects a massive ecosystem spanning approximately 827,000 acres, which is critical for jaguars and migratory birds. Instead of dismantling the site entirely, the government is repurposing the industrial infrastructure into a security base for rangers to fight illegal deforestation. This innovative “oil-to-wilderness” transition prioritizes ecological recovery and water security, setting a new global standard for retiring fossil fuel assets in protected areas.

Guinea worm disease on the brink of being eradicated worldwide
The global campaign to eradicate Guinea worm disease has achieved a record low, with only 10 human cases reported worldwide in 2025. This historic milestone brings humanity to the brink of wiping out its second-ever human disease. The success is driven by the Carter Center’s grassroots strategy, which relies on water filtration and community education rather than vaccines. Despite challenges with animal infections, key endemic regions like Chad have seen significant reductions, proving that persistent, low-tech interventions can defeat even the most debilitating ancient parasites.

China launches world’s largest first compressed air facility
China has successfully launched the world’s largest compressed air energy storage (CAES) facility in Hubei province. This 300-megawatt plant utilizes underground salt caverns to store renewable energy, capable of reducing coal consumption by 45,000 tons and carbon emissions by 109,000 tons annually. This non-lithium technology provides a sustainable, long-duration storage solution that stabilizes the grid and enables greater integration of wind and solar power. The project demonstrates a scalable, eco-friendly alternative to chemical batteries, marking a pivotal advancement for global clean energy infrastructure.
