Ava Community Energy launched a $11.25 million incentive program in California for residential customers to install solar and battery storage systems, allowing customers to share up to 80% of their home batteries. The program offers rebates for both income-qualified and non-income qualified customers, aiming to make electrification more affordable and maintain grid stability. California legislators are advancing a bill to update state resource adequacy rules to include distributed energy devices like residential batteries and electric vehicles, with monthly participation payments provided to customers who participate. Despite funding cuts for the Demand Side Grid Support program, a successful large battery-based virtual power plant, changes will not impact the SmartHome Battery program.

Find The Lego: How Indonesia Can Turn Diesel Generator Retirement Into A Scalable Program
Indonesia is strategically shifting towards replacing remote diesel generation with solar and batteries to reduce CO2 emissions and improve energy efficiency. The estimated capital cost for this transition is around $2.5 billion to $3.4 billion, with a payback period of 3 to 6 years. The country's challenge lies in the complexity of institutional economics and the geographical spread of its population across 17,000 islands. The focus is on creating repeatable infrastructure systems for diesel replacement, rather than custom engineering solutions, to drive down costs and increase efficiency in the renewable energy transition. The goal is to establish a durable and scalable deployment system that will lead to measurable reductions in diesel usage and improved performance across the board.

Cooling solar modules with nanofluids based on graphene oxide, Mxene
An international research group has developed a novel solar module passive cooling system that integrates a three-dimensional oscillating heat pipe (3D-OHP) with different combinations of nanofluids based on hybrid graphene oxide (GO) and a two-dimensional titanium carbide known as MXene (Ti3C2Tx). The system was tested in real outdoor conditions and showed temperature reductions of over 24°C, a 14.9% increase in power output, and an improvement in efficiency. Despite a 31% increase in viscosity, the hybrid nanofluid maintained stability and delivered strong exergy performance while remaining economically competitive. The system has potential for use in urban PV cooling and further research includes optimization of geometry and concentration, integration with PV-battery systems, and comparisons with other advanced nanofluids and surface treatments.

Renewables hit 80 pct share in Australia’s most coal dependent grid for first time
Queensland's grid has reached 80% renewables, driven by solar power, wind, and hydro, despite heavy coal dependence. New projects are fueling the growth of renewables, with households and businesses embracing rooftop solar and batteries. The state government plans to continue burning coal for another two decades, but grid scale batteries are being built throughout the state. Meanwhile, NSW has a slightly higher coal capacity but posted new battery storage records, indicating a shift towards cleaner energy solutions.

France Moved First, But Markets Everywhere Are Signaling Electrification
France has announced a significant increase in state support for electrification, aiming to replace imported molecules with domestic electrons. The package includes a ban on gas heating systems in new buildings, a phaseout of gas heating in social housing units, and subsidies for electric vehicles and trucks. Other European countries are also showing movement towards electrification, with a notable increase in battery electric vehicle registrations in Germany and the UK. The European market is showing increased interest in electric vehicles (EVs) and other clean energy solutions, with rising inquiries and orders for EVs, heat pumps, and solar panels. The section discusses how different regions like Australia, South Asia, Africa, and Latin America are responding to fuel insecurity and the transition towards electrification. Countries with low-carbon power mixes may struggle to convert this into electrification advantages due to grid and market framework issues. The importance of building infrastructure fast enough to meet rising electric demand and avoiding overreading weak signals in the energy transition is emphasized, with electrification seen as a practical language of resilience in the face of repeated fossil fuel shocks.

A Tale of Four Cities on Infill, Emissions, & Political Nerve
The section discusses how four cities – Calgary, Edmonton, Minneapolis, and Vancouver – are approaching the challenge of accommodating more people in existing neighborhoods while reducing infrastructure costs, transport emissions, and building energy use. Calgary initially made a citywide move to allow for more housing diversity but later reversed it due to political backlash. The most effective emissions reductions come from adding homes in location-efficient, transit-supportive, walkable neighborhoods. The article emphasizes the importance of building energy-efficient, compact, mixed-use developments close to transit and amenities to reduce vehicle miles traveled, energy use, and CO2 emissions. Edmonton's zoning bylaw renewal focused on compact growth and climate implications, resulting in a reduction in greenhouse gas emissions. Minneapolis implemented zoning reform in 2019 allowing up to three units on low-density lots as part of a comprehensive plan to reduce greenhouse gas emissions from transportation. Vancouver has a more aggressive approach, allowing up to six dwelling units on a single lot and requiring zero-emissions equipment for heating in new buildings. The overall message is that comprehensive and integrated policies are needed to ensure low-carbon and politically durable urban development, with a focus on infill development, zero-emissions buildings, and strong transport policy.

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.

Made in the shade: How electric vehicles could be the perfect partner to rooftop solar in tropical cities
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.
