An RMI analysis evaluates the viability of residential clean technologies—electric vehicles (EVs), air-source heat pumps (ASHPs), and rooftop solar—in the US following the expiration of federal tax credits under the One Big Beautiful Bill Act of 2025. The report finds that these technologies still provide significant greenhouse gas (GHG) emissions reductions and household cost savings, though the most effective technology varies by region and household archetype.

This research paper introduction from the Institute for Security Studies provides an overview of the current global climate crisis, highlighting record-breaking temperatures in 2024, the increasing frequency of weather-related disasters, and the rising scale of climate-induced displacement. It emphasizes the gap between current policies and the goals of the 2015 Paris Agreement, while noting the persistent rise in atmospheric carbon dioxide concentrations.

This briefing by Zero Carbon Analytics challenges the claim that renewable energy increases electricity prices, arguing that real-world data from the US, EU, Australia, and India often show a correlation between high renewable uptake and below-average power prices.

This policy brief by RMI provides four recommendations for Public Utility Commissions (PUCs) to improve the evaluation of Performance Incentive Mechanisms (PIMs). The document emphasizes the need for recurring evaluations, transparency through public dashboards, portfolio-wide assessments to avoid duplication, and the use of design guidelines to measure net benefits to customers.

This report by Ember analyzes the technical and economic feasibility of achieving 24-hour solar electricity generation using solar panels paired with battery storage. It demonstrates that in sunny regions, near-continuous solar power is now cost-competitive, often cheaper than new coal or nuclear power, due to rapid declines in battery costs and the adoption of Lithium Iron Phosphate (LFP) technology.

This briefing by RMI outlines the economic, health, and environmental benefits of transitioning over 10 million US homes that rely on delivered fuels (oil and propane) to electric heat pumps. It provides data on potential energy savings, carbon pollution reduction, and recommends specific policy interventions and outreach strategies to accelerate this transition.

This report by Ember analyzes the accelerating deployment of battery storage and solar power in the United States, highlighting how batteries are enabling higher solar penetration and displacing fossil fuels, particularly in California and Texas.

This report by the World Resources Institute analyzes the state of clean energy in the United States through 2024, highlighting record growth in solar and battery storage alongside significant headwinds including grid capacity limits, rising local opposition, and policy uncertainty under the Trump administration.

This briefing analyzes the rise of climate litigation against major fossil fuel companies, noting that 86 lawsuits have been filed, with annual filings nearly tripling since 2015. The most prevalent cases seek compensation for climate damages (38%), followed by claims of misleading advertising (16%) and demands for emissions reductions (12%). The report highlights a shift toward criminal litigation, targeting executives for 'crimes against humanity' and involuntary manslaughter, and notes a growing trend in challenging project permits and corporate directors' liability.

This briefing by RMI argues that battery energy storage systems (BESS) are a cleaner, more flexible, and often more cost-effective alternative to fossil fuel resources for maintaining electric grid reliability. It details how batteries can manage variable renewable energy, provide critical stability services, and support grid restoration, while urging utilities to adopt all-source procurement processes to identify the most cost-optimal reliability solutions.

This briefing by Zero Carbon Analytics examines the causal link between fossil fuel emissions and the increasing frequency and intensity of extreme weather events. It details the role of 'Carbon Majors' in global emissions, the financial disparity between industry profits and climate damages, and the growing use of litigation to hold these companies accountable. The document argues that a managed phase-out of fossil fuels, through both supply and demand reductions, is essential to limit global warming to 1.5 degrees Celsius.

This report by RMI provides guidance on using Performance-Based Regulation (PBR) as an alternative to traditional cost-of-service regulation (COSR) to better align utility incentives with customer and societal interests, specifically regarding decarbonization, affordability, resilience, and social equity.

This guide by RMI introduces Performance-Based Regulation (PBR) as a regulatory approach for electric utilities designed to align utility incentives with customer and societal interests. It contrasts PBR with traditional cost-of-service regulation (COSR), which the document argues creates perverse incentives such as 'gold plating' and 'capex bias' that hinder the clean energy transition. The guide details various PBR tools—including revenue decoupling, multi-year rate plans, and performance incentive mechanisms—and provides a framework for moving from incremental to comprehensive PBR reform.

The EESI 2023 Climate, Environmental, and Energy Congressional Hearings Tracker lists the hearings conducted by various U.S. House and Senate committees throughout 2023. The tracker highlights a high volume of activity in the House Committee on Natural Resources (28 hearings), the House Committee on Energy and Commerce (24 hearings), and the Senate Committee on Environment and Public Works (22 hearings). Key themes across these committees include the implementation of the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, energy security, critical mineral supply chains, water resource management, and the economic risks of climate change.

This research paper by RMI analyzes energy burden—the proportion of household income spent on electricity and fuel—across all 50 US states using 2020 Energy Information Administration data. It finds that extremely low-income households face a disproportionately high energy burden, often exceeding the 10% threshold for energy poverty, and evaluates how federal funding from the Inflation Reduction Act (IRA) and specific state-level policies can mitigate these burdens while pursuing decarbonization.

This report by Energy Innovation analyzes the cost savings of operating electric vehicles (EVs) compared to gas-powered vehicles across the United States, focusing on 'fill-up' costs for sedans, SUVs, and trucks. Using a custom cost comparison tool, the authors find that EV drivers in every state save money per trip and annually, though the magnitude of these savings varies significantly based on state-level electricity rates and gasoline prices.

This case study describes RMI's efforts to make rooftop solar more accessible to low- and moderate-income (LMI) communities through inclusive Solarize campaigns. Between 2021 and 2022, RMI organized cohorts of 27 cities to implement bulk-purchasing programs combined with grants and community partnerships to reduce financial and administrative barriers to solar adoption.

This briefing by RMI outlines the energy affordability crisis in the US, driven by high fossil fuel prices and rising electricity rates, and provides a toolkit of short-term and long-term regulatory solutions for state public utility commissions to reduce the energy burden on vulnerable households.

This policy brief by RMI outlines how the Georgia Public Service Commission (PSC) can reduce the high energy burden on Georgia electricity customers through specific regulatory reforms. It argues that while Georgia has low electricity rates, it has some of the highest bills in the contiguous US, disproportionately affecting low-income and minority households. The document proposes four primary levers for the PSC: implementing securitization, reforming the Return on Equity (ROE) for Georgia Power, establishing fuel-cost sharing mechanisms, and updating system planning to align with the Inflation Reduction Act (IRA).

This report by RMI examines the shift toward "climate-forward efficiency," which prioritizes energy efficiency, electrification, and demand flexibility specifically to reduce greenhouse gas (GHG) emissions. It analyzes the use of Performance Incentive Mechanisms (PIMs) to align utility business models—which traditionally favor capital investment and sales growth—with state climate goals.
