New research suggests that electric vehicles (EVs) could help manage distributed solar generation in tropical cities prone to thunderstorms by using parked EVs to store solar energy and act as temporary grid capacity during cloudy periods. This approach could mitigate the need for costly infrastructure upgrades to handle fluctuations in electricity generation caused by tropical thunderstorms, allowing for more efficient use of the existing grid and integration of more solar photovoltaics without the need for additional transmission line capacity. The research focuses on a decentralized electric vehicle charging strategy in Singapore that aligns with urban mobility patterns, showing potential for large-scale photovoltaic integration in tropical cities through decentralized EV charging even in car-light environments.

Wired for Security: The EU’s Post-2030 Climate Architecture
The EU's 2040 climate target focuses on electrification powered by domestically generated renewable energy to reduce energy insecurity and dependence on imported fossil fuels. The post-2030 framework should prioritize clean electrification, with legislation like the Renewable Energy Directive and Energy Efficiency Directive playing key roles. The emphasis is on resilience and reducing exposure to global fossil fuel markets and geopolitical crises. Additionally, the EU Climate Law should be amended to include a legal obligation covering non-CO2 aviation effects to ensure sector-specific accountability and clear linkage to the 2040 trajectory. Carbon markets should complement national climate action, with revenues funding clean mobility and building renovation.

Balcony Solar Is Here, And It’s Not Just For Balconies
Lawmakers in states like Utah, Virginia, and Maine are introducing legislation to promote the use of balcony solar panels, which plug into household outlets and reduce electricity usage from the grid. The movement has faced hurdles in the US due to utility and landlord restrictions, safety concerns, and aging housing stock, but efforts are being made to address these issues. In Maine, where electricity rates have increased by 68% over the past five years, the potential benefits of balcony solar systems are being highlighted. Non-profit organization Bright Saver is advocating for balcony solar in the US, with kits already available in California, and supermarket chain Lidl is planning to carry plug-in solar panels at its UK stores. The Biden-era federal tax credits for household renewable energy improvements are seen as a helpful incentive for investing in solar energy. Companies are establishing a presence in solar-friendly states on the East Coast, using balcony solar kits to generate clean electricity and reduce monthly utility bills.

Rooftop solar now accounts for one-fifth of Puerto Rico’s generation capacity
Rooftop solar installations in Puerto Rico have surpassed natural gas to become the second-largest power generation source in the territory, accounting for 20% of all capacity. Distributed solar has outpaced all other energy sources in Puerto Rico over the past decade, with 81% of new generating capacity added between 2016 and 2025 coming from rooftop systems. The growth in solar capacity has not displaced other generation sources like petroleum, natural gas, and coal. Additionally, the adoption of distributed energy storage, including battery systems, has grown rapidly in response to grid resilience challenges, with more than 171,000 households and businesses installing battery systems by the end of 2025. The new CEO of LUMA, Janisse Quiñones, is focused on improving grid reliability in Puerto Rico, with industry group SESA optimistic about increased collaboration under Quiñones' leadership and working towards advancing policies that support rooftop solar and battery storage as key components of Puerto Rico's energy future.

Analysis: How ‘plug-in solar’ can save UK homes £1,100 on energy bills
Plug-in solar panels have the potential to save households money on electricity bills, with a payback period of around 5 years and potential lifetime savings of £1,100. The UK government's clean-energy measures include the introduction of plug-in solar panels, which can be easily installed on balconies and in gardens. If 3 million households adopt plug-in solar, it could generate 1.2 terawatt hours of energy, saving households over £330 million and reducing imported LNG. This technology not only benefits homeowners but also allows renters to participate in the clean energy transition and benefit from clean energy in their homes.

Nepal’s EV revolution pays off as oil crisis causes pain at pumps
In Nepal, high rates of electric vehicle (EV) adoption among minivan drivers have helped reduce the impact of rising fuel prices caused by global energy market turmoil. Nearly three-quarters of new cars sold in Nepal are now electric, with the country being a leader in EV adoption. The government has introduced policies to encourage EV adoption, including cutting import taxes for EVs and investing in charging stations. The shift to EVs not only cuts air pollution and helps progress towards net-zero emissions goals but also shields the country's foreign currency reserves from spikes in global oil prices and improves public transport. Public and private investment is crucial to reduce dependency on fossil fuels in Nepal, with a need for policy changes to support the transition to larger electric buses and improve the electricity infrastructure for EVs.
