Renewables, Led By Solar, Were Largest Source of Energy Supply Growth Globally in 2025
In 2025, the US accounted for 47% of the world's CO2 emissions growth due to fossil fuel-biased policies and AI infrastructure, while renewables, particularly solar power, saw significant growth in total energy supply. Despite fossil fuels dominating global energy supply, positive trends include the growth of solar and wind power, decline in China's oil and diesel use, and Europe's reduction in fossil fuel dependence through renewable energy expansion. The EU's accelerated deployment of wind and solar power has led to a decrease in coal and gas generation, with wind and solar generating more power than coal, gas, and oil combined by 2025. This shift has saved the region €72bn in fossil fuel imports between 2022 and 2025, driven by the cost-effectiveness, stability, and ability of solar power to reduce fossil fuel dependency globally.

Passive mooring system enables floating PV to track water-level changes
Researchers from Morocco have developed a novel mooring system for floating PV systems that automatically adjusts to water-level changes, reducing platform motion without the need for active control or external energy. The system, based on a counterweight-and-pulley mechanism, showed significant reduction in horizontal displacement and achieved a high tracking efficiency of 75%. This passive mooring system offers a mechanically simple design for stable FPV installations in remote, low-maintenance environments. Future research will focus on scaling up, testing with real hydrodynamic loading, and field pilot deployment after the system's proof of concept was presented in a study published in Scientific Reports.

Triple-junction all-perovskite solar cell based on graphene oxide bilayer achieves 27.3% efficiency
An international research team has developed a novel triple-junction all-perovskite solar cell technology using a graphene oxide-SAM bilayer contact strategy to enhance performance and stability. By integrating graphene oxide, they improved interfacial passivation and buried interface morphology, leading to an increase in cell efficiency from 23.6% to 25.1%, with further optimization reaching a champion efficiency of 27.3%. This technology has the potential to achieve efficiencies beyond 30% by reducing charge-transport resistance and improving perovskite quality and energy-level alignment, making it a promising solution for higher industrial readiness levels. The study, published in Joule, was conducted by a group of academics from Germany and Switzerland.

‘Australian first’ compressed CO2 battery project takes shape
Victoria's State Electricity Commission (SEC) is partnering with Energy Dome to deploy a 10-hour duration compressed CO2 battery energy storage system near Morwell in the Latrobe Valley, marking Victoria's first long-duration energy storage facility and Australia's first commercial compressed CO2 battery. This technology aims to ensure around-the-clock reliability of supply for renewable energy generation from wind and solar, supporting Victoria's transition to clean energy and helping meet its 2030 clean energy targets. Additionally, stakeholder and community consultation has begun for the new SEC Energy Works energy innovation precinct in the Latrobe Valley, which will focus on developing new energy infrastructure and storage technologies to further support the state's future energy system. Projects at SEC Energy Works will contribute to the government-owned renewable energy company's portfolio, including the Melbourne Renewable Energy Hub and the SEC Renewable Energy Park, emphasizing the importance of energy innovation, early investment, and confidence building for new energy technologies.

Head of IEA Roasts Europe for “Slow Electrification”
The International Energy Agency (IEA) criticizes Europe's low electrification rate of 23%, highlighting the vulnerability of the EU's heating, transport, and industrial sectors to supply disruptions due to heavy reliance on imported fossil fuels. Despite industry pushback, the EU is considering plans to lower taxes on electricity and support the adoption of green technologies like heat pumps and electric cars to catch up to countries like China, Japan, and South Korea with electrification rates above 30%. The question remains whether the EU will make significant progress in increasing electrification to reduce dependence on fossil fuels and mitigate climate change.

Study finds heatwaves cause hourly losses of up to 90% in PV plants in Iberian peninsula
Scientists analyzed the performance of three photovoltaic plants in Spain and Portugal during extreme heat events in 2024 and 2025, finding that heatwaves can cause significant yield losses in PV energy production. High temperatures affect module efficiency and trigger thermal derating in inverters, with yield losses concentrated during the hottest hours of the day. The study compared production data with meteorological information, confirming the dataset's suitability and highlighting the need to consider actual weather inputs during extreme heat events for accurate PV generation predictions. The European solar sector is now focused on improving the resilience of PV installations against production losses during periods of extreme heat, moving away from solely maximizing annual generation.
