The roadmap for Oʻahu's energy future includes building a foundation of rooftop and canopy solar, batteries, EV charging, and district-cooling projects by 2030. The goal is to eliminate oil generation and H-POWER as power sources and decarbonize liquid fuels by the 2040s. The transition aims to reduce harm, lower costs, strengthen resilience, and reduce dependence on imported fossil fuels. The decision on the next steps belongs to Hawaiʻi's communities, workers, institutions, and leaders.

Rust-powered batteries could help crack Europe’s energy storage gap
A Dutch startup, Ore Energy, has developed iron-air batteries that can store and release electricity using a simple chemical process of rusting and de-rusting, offering a cheaper and critical mineral-free alternative to traditional lithium batteries. As Europe aims to reduce its reliance on critical mineral supply chains and increase battery production for renewable energy storage and electric vehicles, the need for long-duration storage batteries is becoming increasingly important. Companies like Ore Energy, Form Energy, Noon Energy, and E-Zinc are working on innovative long-duration energy storage technologies, with a mix of different technologies seen as necessary to support grid reliability as renewable energy sources grow. Europe must find sustainable solutions for long-duration storage to avoid overbuilding, curtailment, and backup generation challenges in transitioning to cleaner energy sources and achieving climate goals.

How a robot named Bear is making solar farm maintenance safer and more efficient
Australia's national science agency has repurposed robots from the mining industry to inspect solar panels in large-scale PV projects, equipped with sensors like LiDAR and thermal infrared cameras to detect faults such as dust build-up, physical damage, and hotspots. This technology aims to improve efficiency, safety, and automation in solar farm maintenance, replacing unskilled labor with skilled regional jobs. The use of next-generation robotics is accelerating the energy transition and supporting the path to net zero by collecting data for proactive maintenance decisions and leveraging experience from other industries to benefit the renewable energy sector. Early detection of faults is crucial to maintain panel performance, enhance energy output stability, and prevent fires at solar projects.

Solar and wind reach record 17% of US power generation
In 2025, wind and utility-scale solar in the US accounted for a record 17% of electricity generation, producing 760,000 GWh. Solar generation increased by 34%, while wind power remained the larger source of zero-carbon electrons. The growth in renewables is driven by increasing electricity demand from data centers and industrial electrification. The future integration of renewables will rely on managing interconnection backlogs and deploying battery energy storage systems. An historic expansion of the US electric grid is expected in 2026, with 86 GW of new utility-scale generating capacity, primarily from solar and battery storage technologies.

South Australia on path to 100 pct net renewables next year after Labor landslide and Liberal backflip
South Australia's Liberal government, which aimed for 100% net renewables, lost power to Labor in 2022 and was further weakened in the 2026 election due to indecision on net zero and the energy transition. Labor, now in charge, plans to achieve the 100% renewables target by 2027 through new wind and solar farms, batteries, and a connection to New South Wales. South Australia will become the first gigawatt-scale grid to reach this milestone using wind and solar as the sole renewable sources, supported by batteries and gas-fired generation. Additionally, the state is leading in consumer energy integration, attracting interest from energy-intensive industries and presenting a significant economic opportunity for the development of renewable resources and new industries.

Pioneering community solar and battery project launches after “12 years of hard work”
The Goulburn Community Solar Farm in New South Wales, Australia, has been completed and will soon start generating power for its 288 local investors. Led by the Goulburn Community Energy Co-operative, the project features a 1.4 MW solar farm and a 4 MWh battery, showcasing the potential of community energy projects in the shift towards clean energy. Despite facing challenges, the project received support from the community, local government grants, and partnerships with companies like Trina Solar. Additionally, a new solar farm in Goulburn, Australia, led by Smart Commercial Solar, is set to power 500 homes with advanced clean-energy technology components from Trina Solar. Both projects highlight the accessibility and benefits of community-owned renewable energy solutions in the fight against climate change.

Entso-E report finds systemic failures behind 2025 Iberian blackout
Entso-E's final root cause report on the April 28, 2025 blackout in Spain and Portugal identified systemic failures in voltage control, reactive power management, and regulatory frameworks, with manual disconnections and lack of real-time monitoring contributing to the blackout. The investigation was hindered by incomplete data, particularly from generators below 1 MW. Entso-E issued 22 recommendations to strengthen European grid resilience, focusing on voltage control, oscillatory stability, disconnection behavior, and defense and restoration, including improving reactive power resources, real-time visibility, and harmonizing operating voltage ranges. The article also discusses recommendations for improving small-scale generation, defense, and restoration in the context of climate-related incidents, suggesting adaptive load shedding schemes, better coordination among operators, and standardized data collection frameworks for future investigations.

Copper’s Battery-Equipped Induction Range Makes Electrification & Storage Accessible
Copper's electric range, named "Charlie," features a convection oven and induction cooktop with a unique battery system that allows for extended oven use without the need for costly electrical upgrades. The battery can be charged over time and programmed to take advantage of off-peak power or solar energy. This innovative design aims to make electric cooking more accessible, especially in older buildings with limited electrical capabilities. By integrating batteries into appliances like refrigerators and EV chargers, people can shift when they draw electricity from the grid, helping stabilize the grid and increase renewable utilization. This approach makes storage more available to more people, especially in apartments, and can lead to greater adoption of electrification, ultimately making the benefits of climate solutions more accessible to a wider range of people.
