AN ADAPTIVE APPROACH TO PROMOTE SYSTEM OPTIMIZATION
The paper outlines an adaptive approach to electricity policy for a hypothetical jurisdiction, focusing on modernizing rate design and market structures to integrate distributed energy resources (DERs). It argues that traditional cost-of-service models are outdated due to technological advances in home automation and on-site generation. The author proposes four key principles for retail rates—cost causation, transparency, adaptability, and customer sophistication—and four principles for market structure—level playing fields, grid stability, innovation, and transparency. The framework is designed to be applicable to both vertically integrated utilities and market-based systems, emphasizing the use of Integrated Resource Plans (IRPs) and Integrated Distribution Plans (IDPs) to ensure long-term system optimization.

Improving reliability and environmental justice en route to 85 percent clean electricity in California by 2030
A technical analysis indicates California can reach 85 percent carbon-free electricity by 2030 even under extreme stressors, such as the August 2020 heat waves and the retirement of one-third of natural gas capacity. To support this, the brief recommends diversifying clean energy resources (including offshore wind and geothermal), phasing out natural gas plants—particularly in disadvantaged communities—and leveraging demand-side resources like energy efficiency and demand response. It also suggests improving regional coordination across Western states and refining reliability evaluation tools used by the CPUC, CEC, and CAISO.

Advanced Clean Cars II: Electric vehicles can pave the way for clean air and a growing U.S. economy
The document argues that the adoption of California's Advanced Clean Cars II (ACC II) rule by all 16 '177 States' would significantly increase electric vehicle (EV) market share, reduce greenhouse gas emissions, and provide substantial public health and economic benefits. Modeling suggests that while federal Inflation Reduction Act (IRA) tax credits provide a temporary boost to EV sales, the ACC II mandate is necessary to sustain growth, potentially leading to 81 percent EV market share by 2050. The report highlights cumulative reductions of 1,310 million metric tons of CO2e, the prevention of 5,000 premature deaths, and the creation of 300,000 new domestic jobs by 2050.

Evaluating Policies for California to Reach 55 Percent Reductions by 2030 using the Energy Policy Simulator
The California Energy Policy Simulator (EPS) indicates that a 55 percent reduction in emissions by 2030 is achievable without new technologies and would generate significant economic and social benefits. The scenario projects a $55.4 billion increase in state GDP, the creation of 235,000 total jobs, and the avoidance of 1,829 premature deaths by 2030. Achieving this target requires accelerating the deployment of electrification, hydrogen, and carbon capture in industry, as well as reaching 90% clean energy for grid-scale generation by 2030.

California Energy Policy Simulator: Earlier Action Delivers Climate, Economic, Health Benefits
Energy Innovation uses the California Energy Policy Simulator (EPS) to propose a 'Deeper Decarbonization Scenario' for California. This pathway prioritizes mature technologies—such as electric vehicles, renewable energy, and electric appliances—to achieve emissions reductions of 47 percent below 1990 levels by 2030, compared to the state's current Draft Scoping Plan which relies on uncertain carbon dioxide removal. The proposed scenario includes a 100 percent zero-emission vehicle sales standard for cars and light-duty trucks by 2030, 100 percent electrification of new appliances by 2030, and a carbon neutral electricity system by 2035. These actions are estimated to add $28 billion to the state's economy and create nearly 170,000 new jobs by 2030, while preventing over 1,300 deaths and 26,600 asthma attacks annually by 2030.

ENERGY LEADERSHIP IN A TIME OF NEED: A BLUEPRINT FOR STATES
The document argues that U.S. states should implement 'no-regrets' actions in building and industrial efficiency to counter the negative economic impacts of the One Big Beautiful Bill Act (OBBBA), which is projected to cost households $170 billion in higher energy bills and reduce GDP by $1.1 trillion by 2035. It advocates for the deployment of heat pumps and electric boilers, noting that residential heat pumps have held a 56 percent market share for space heating since 2021. The briefing specifically highlights the potential of industrial electric heat pumps for low-temperature heat (under 200 °C), which are two to four times more efficient than fossil-fueled versions but currently make up less than 2 percent of the market. To overcome barriers such as upfront capital and high electricity rates, the document recommends a suite of policy actions, including adopting modern energy codes, implementing building performance standards, providing point-of-sale rebates, and creating revolving loan funds.

RELIABLY REACHING CALIFORNIA’S CLEAN ELECTRICITY TARGETS STRESS TESTING ACCELERATED 2030 CLEAN PORTFOLIOS FACT SHEET
The document finds that reaching an 85% clean electricity target by 2030 is feasible and reliable for California, even under most simultaneous stress conditions. Analysis indicates that while solar and battery storage are primary drivers, a diverse portfolio including offshore wind and geothermal reduces dependence on imports and gas. Battery storage specifically reduces the 'duck curve' ramping requirements by an average of 42%. While the state can retire nearly a third of its in-state gas fleet under certain conditions, some gas remains necessary for reliability unless replaced by comparable firm clean resources. The study emphasizes that sharing power with the rest of the Western United States is more optimal than a 'go it alone' approach.

150+ CIVIL SOCIETY ORGANIZATIONS CALL ON CALIFORNIA TO ENDORSE THE FOSSIL FUEL NON-PROLIFERATION TREATY PROPOSAL
A coalition of more than 150 civil society organizations is urging California to support Senate Joint Resolution (SJR) 2 (Gonzalez). This resolution calls for an end to fossil fuel expansion, a fair phase-out of coal, oil, and gas, and the establishment of an international Fossil Fuel Non-Proliferation Treaty to address the climate crisis at its root. The signatories argue that because fossil fuels are omitted from the Paris Agreement, a specific international mechanism is required to stop production expansion and ensure a just energy transition, particularly for Indigenous Peoples and communities of color.

Latine Community Priorities and The Infrastructure Investment and Jobs Act
The report analyzes 308 projects totaling over $3.1 billion in IIJA expenditures across California, Colorado, Florida, New York, and Texas. It finds that while significant funds are reaching these states, investments are heavily skewed toward large-scale infrastructure projects managed by the Army Corps of Engineers, with relatively low funding for public lands and greenspaces. The analysis highlights a gap in orphaned well remediation near Latine communities and notes that carbon capture investments in Texas primarily benefit private industry. However, it identifies successes in fenceline air monitoring and climate pollution planning grants that have reached grassroots organizations and Latine-led initiatives.
