RMI outlines five key factors—facility suitability, electricity costs/net metering, energy efficiency, battery sizing, and available funding—to help US communities deploy solar-plus-battery microgrids that serve as resilience hubs during disasters.

The document examines the financial mechanisms of utility regulation, specifically the gap between the allowed return on equity (ROE) and the cost of equity (COE). It argues that current ROEs are excessively high, creating a 'capex bias' that incentivizes expensive capital projects over cost-effective solutions like energy efficiency. By analyzing price-to-book ratios and applying discounted cash flow models, the authors estimate that the required return for investors is significantly lower than currently approved rates. The guide provides a framework for stakeholders to challenge inflated COE estimates by correcting flawed model assumptions regarding interest rates, growth rates, and historical means. It further dismisses common industry claims that lower ROEs would limit access to capital or increase customer costs via credit rating downgrades.

The U.S. clean energy sector saw record solar and battery storage installations in 2024, with renewables accounting for approximately 90% of new capacity. However, progress is hindered by grid interconnection backlogs, rising local opposition, high interest rates, and supply chain shortages. The report also notes a slowdown in EV sales growth and warns that the Trump administration's policies may create further roadblocks to decarbonization.

The document highlights that while medium- and heavy-duty vehicles (MHDVs) make up only about 10% of US on-road vehicles, they contribute over half of fine particulate matter and nitrogen oxide emissions. It reports an exponential increase in zero-emission MHDV registrations from under 1,000 in 2019 to over 27,000 in 2023. The analysis finds that over 85% of MHDVs travel fewer than 100 miles daily, making them suitable for current battery-electric technology. While operational costs for electric trucks are lower, up-front costs remain a barrier for larger models, necessitating continued state and federal policy support and the expansion of charging infrastructure along freight corridors.

The report analyzes the environmental, health, and economic impacts of medium- and heavy-duty vehicle (MHDV) pollution in the US and advocates for an accelerated transition to battery-electric trucks. It highlights that while MHDVs make up a small fraction of road vehicles, they contribute a disproportionate share of NOx, PM2.5, and greenhouse gas emissions. The document argues that battery-electric vehicles (BETs) are technically and economically superior to hydrogen fuel-cell alternatives for most duty cycles. It details the role of state policies like California's Advanced Clean Trucks (ACT) regulation and federal investments from the Inflation Reduction Act (IRA) in driving adoption. The report concludes with recommendations for expanding charging infrastructure, implementing indirect source rules for warehouses, and maintaining high-road labor standards during the transition.

The Federal Hydrogen Hub Program aims to establish a national hydrogen network through seven regional hubs, with funding distributed across four phases over 8-12 years. While hubs claim local economic and environmental benefits, the guide notes that many proposed projects may increase pollution or waste energy. As of January 28, 2025, the DOE has instructed all recipients to cease activities related to Community Benefits Plans, pending further guidance.

The four lower Snake River dams cause an average additional water loss of approximately 30,000 acre-feet per year due to evaporation compared to free-flowing conditions. This loss is valued at roughly $110 million as a water right and is equivalent to the water needed to grow 8,000 acres of apples or supply the household needs of 240,000 people. Future projections (2025–2055) suggest these losses will persist or slightly increase, ranging from 30,100 to 32,800 acre-feet per year across eight global climate models.

The document outlines the framework for state Clean Electricity Standards (CES), emphasizing that effective policies must be mandatory, technology-inclusive, and ambitious. It contrasts CES with Renewable Portfolio Standards (RPS) by highlighting the inclusion of clean firm resources like nuclear and carbon capture. The brief details various design options—such as retail sales vs. emission-based standards—and explains how federal incentives from the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) reduce implementation costs. It also discusses advanced features like clean capacity standards and hourly matching to accelerate the deployment of long-duration storage and firm clean power.

The document describes Canada's dual-track carbon pricing approach, distinguishing between consumer carbon taxes and industrial systems for large emitters. It details two primary industrial models—emissions-intensity based systems and cap-and-trade systems—and compares their application across different Canadian jurisdictions, highlighting the specific frameworks used in Alberta, Quebec, and the federal backstop system.

Canada employs a dual carbon pricing approach consisting of a consumer carbon price and an industrial carbon price for large emitters. To prevent carbon leakage and protect trade-exposed industries, Canada utilizes large-emitter trading systems (LETS), which primarily take the form of intensity-based systems or cap-and-trade. There are nine LETS across the country, including the federal output-based pricing system (OBPS) and Alberta's Technology Innovation and Emissions Reduction (TIER) Regulation, the latter being the largest due to Alberta's share of industrial emissions. Quebec operates the only cap-and-trade system in Canada, which is integrated with the Western Climate Initiative. The Northwest Territories uses a unique fuel levy with rebates rather than a trading system.

Earthjustice reports a series of legal victories in 2024, including a landmark settlement to decarbonize Hawaii's transportation system by 2045, the cessation of coal leasing in the Powder River Basin, and a historic Inter-American Court of Human Rights ruling requiring Peru to remediate lead pollution in La Oroya. The organization also secured wins against cryptomining operations in New York, fossil fuel infrastructure expansion in New Jersey, and the loss of wetlands protections following the U.S. Supreme Court's Sackett v. EPA decision, notably helping Colorado pass legislation to reinstate wetland protections in May 2024. Additionally, the report highlights efforts to regulate PFAS in plastic containers, limit lead wheel weights, and protect endangered species such as the Cook Inlet beluga whale and Pacific sardine.

The report argues that private equity firms prioritize high returns (at least 15%) over short timelines (3-5 years), leading to deferred maintenance and increased tenant instability. It proposes a toolkit of interventions, including rental registries with beneficial ownership disclosure, just cause eviction protections, landlord licensing with portfolio caps, and right of first refusal legislation. The document also examines federal legislative attempts to curb consolidation through tax penalties and transfer taxes, while highlighting the challenge of state preemption of local housing justice measures.

The report argues that the US can significantly reduce its reliance on newly mined minerals for electric vehicle (EV) batteries by prioritizing energy efficiency, right-sizing battery range, and implementing robust recycling policies. Through a 'Very Low Demand Scenario,' the authors demonstrate that newly mined lithium needs could be reduced by 48% from 2025 to 2050, saving 1.5 million metric tons of material. The analysis emphasizes that while electrification is essential for decarbonization, a systems-wide approach—including investments in public transit and rail to reduce vehicle miles traveled (VMT)—is necessary to create a sustainable and just supply chain.

As of October 2024, there are 12,241 committed electric school buses in the U.S., with nearly 5,000 already delivered or operating. Adoption is heavily driven by the EPA's Clean School Bus Program, which funds 67% of all commitments and prioritizes high-poverty, rural, and tribal districts. While California leads in absolute numbers, the Northeast and Midwest have seen significant percentage increases. Seven states have enacted statutory zero-emission transition requirements, and WRI projects that 62% of all school bus sales will be electric by 2032 following revised EPA greenhouse gas emission standards.

Climate Central's analysis of U.S. data from 1970 to 2024 shows that winter is the fastest-warming season for 74% of analyzed locations. Average winter temperatures rose by 4°F across 235 locations, with the highest warming seen in the Upper Midwest, Northeast, and Ohio Valley. The report notes a decrease in freezing nights and shorter cold streaks, alongside an increase in warmer-than-normal winter days. These trends impact western water supplies, residential energy use, the $27 billion fruit and nut industry, and the prevalence of disease-carrying pests.

The document outlines a three-step approach for utilities to incorporate the DOE's Energy Infrastructure Reinvestment (EIR) program into resource planning: modeling portfolio-wide savings from low-interest financing, prioritizing 'clean repowering' at existing fossil sites, and optimizing transmission investments. It argues that failing to model these factors leads to suboptimal resource portfolios and missed savings. The brief provides technical guidance on calculating forward interest rates, managing compliance costs (such as NEPA and the Davis-Bacon Act), and leveraging the EIR's $250 billion lending authority to accelerate the clean energy transition while reducing costs for ratepayers.

The Private Equity Stakeholder Project and United Farm Workers argue that Instar Asset Management has violated the PRI's integrity by ignoring labor abuses at Windmill Farms, including wage theft, gender discrimination, and union-busting, despite Instar's public ESG policies.

The document argues that the Advanced Clean Fleets (ACF) regulation is feasible due to extensive state and federal funding and the availability of fuel cell electric vehicles (FCEVs) for long-haul and drayage trucking. It outlines the ACF's ZEV requirements for government, high-priority, and drayage fleets, and lists numerous financial incentives such as the HVIP and the Inflation Reduction Act. CATF emphasizes that FCEVs are critical for routes over 300 miles where battery electric vehicles (BEVs) are less efficient, and notes that California is actively building the necessary hydrogen refueling infrastructure.

The document examines the prevalence of perfluoroalkyl and polyfluoroalkyl substances (PFAS), known as "forever chemicals," in the U.S. environment and population. It details the health risks, including cancer and immune suppression, and outlines the regulatory response led by the EPA's 2021 Strategic Roadmap and the 2024 National Primary Drinking Water Regulation. The brief also covers state-level phase-outs, legislative efforts in the 118th Congress, and technical challenges in remediating PFAS from water and soil.

The report finds that the Government of Canada is providing an inefficient fossil fuel subsidy to the oil industry by charging transportation tolls on the Trans Mountain Pipeline (TMP) that are significantly below marketplace costs. Using three different valuation methods, the report estimates the total subsidy to be between CAD 8.7 billion and CAD 18.8 billion, which translates to a cost of CAD 581 to CAD 1,255 per Canadian household. The analysis concludes that the project fails all criteria for an 'efficient' subsidy and that the overall cost-benefit analysis shows a net cost to Canada of CAD 23.1 billion. To phase out this subsidy, the author recommends either raising tolls to economic levels or implementing a cost-recovery levy of CAD 1.00 to CAD 2.00 per barrel on Western Canadian oil shipments.
