  • 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.

  • Rooftop solar reaches 20% of Puerto Rico’s generation mix

    In 2025, rooftop solar capacity in Puerto Rico reached 1.5 GW, surpassing natural gas as the second-largest generation source, driven by electricity reliability issues. Distributed generation resources, particularly rooftop solar with battery systems, have seen significant growth. LUMA Energy, the island's grid operator, is working to transform and stabilize the grid. Distributed battery storage has also increased, reaching a total energy capacity of 2,864 megawatt hours. Despite setbacks like Hurricane Maria, rooftop solar generation has steadily increased, contributing to Puerto Rico's total generation capacity exceeding 7 GW.

  • California approved a gas pipeline solution. Now comes the hard part.

    California utilities are facing challenges in transitioning away from fossil fuels, with Senate Bill 1221 proposing the creation of "decarbonization zones" to retire gas pipelines and promote electric appliances. Despite potential exclusions based on certain criteria, the bill aims to realign incentives to prioritize climate goals over profit. The success of SB 1221 hinges on regulators using their authority to focus on pollution burden, vulnerability, and transparency in project data, ensuring that climate action aligns with lower bills and prudent spending of ratepayer dollars. This bill represents a step towards meeting climate goals and controlling costs associated with gas pipeline replacements, with a specific focus on low-income communities.
