This case study by RMI examines how electric rate design can reduce financial barriers to heat pump adoption by aligning utility tariffs with the actual costs of service. By analyzing four different approaches in the United States, the document demonstrates that electrification-friendly rates can lower energy bills for heat pump users and improve grid efficiency by recognizing that heat pumps primarily increase demand during winter months, often utilizing existing capacity in summer-peaking systems.

This report provides a framework for conducting a Gas System Analysis (GSA) to help regulators and decision-makers evaluate the prudence of gas utility infrastructure investments, reduce consumer costs, and align utility operations with climate and public health goals.

This RMI fact sheet examines the practice of gas line extension allowances—subsidies where existing customers fund the cost of connecting new buildings to the natural gas system—and the movement among US states to phase them out to lower utility bills and support electrification.

This guide outlines the Renewables Investment for Social Equity (RISE) model, which enables tax-exempt entities to use the IRS 'direct pay' (elective pay) mechanism to deliver affordable solar energy to low- and moderate-income (LMI) households. The model allows tax-exempt organizations to own solar systems, install them at low or no upfront cost for residents, and recover costs via the Clean Electricity Investment Tax Credit (ITC).

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.

In 2024, wind and solar combined to produce 17% of US electricity, surpassing coal (15%) for the first time. While electricity demand rose by 3%, solar generation grew by 27%, adding more generation than gas to meet this demand. Despite the growth in clean energy, overall power sector CO2 emissions rose slightly by 0.7% because gas generation increased to meet rising demand, though carbon intensity reached a record low.

In 2024, wind and solar combined to produce 17% of US electricity, surpassing coal for the first time nationwide. This shift is driven by market dynamics, cost-effective renewables, and state-level policies, with 24 states now generating more electricity from wind and solar than from coal.

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.

The provided document is a public disclosure copy of the 2024 IRS Form 990 and associated schedules for the Environmental and Energy Study Institute (EESI), a 501(c)(3) non-profit organization. It details the organization's financial status, governance, and program accomplishments for the 2024 calendar year, including its mission to provide science-based information on climate and energy to policymakers.

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.

In May 2024, the US Departments of Agriculture (USDA) and Housing and Urban Development (HUD) updated minimum energy standards for new construction, requiring new covered buildings under four stories to comply with the 2021 International Energy Conservation Code (2021 IECC) and taller buildings to meet ASHRAE/ANSI Standard 90.1-2019. These updates, combined with 45L tax credits from the Inflation Reduction Act (IRA), make high-performance multifamily housing financially viable, particularly for all-electric constructions and those in specific climate zones.

Data center power demand in the US is projected to reach 35 GW by 2030, potentially accounting for 7.5% of total electricity consumption. RMI argues that this surge presents an opportunity to set a precedent for future large-scale electrification (e.g., EVs, manufacturing) by prioritizing energy efficiency, demand flexibility, grid-enhancing technologies (GETs), and carbon-free energy procurement. The document highlights the risk of utilities defaulting to new gas generation and urges regulators to implement system-level 'zoning' for the grid and equitable cost allocation for upgrades.

This guide by RMI outlines how local and state decision makers can utilize the Inflation Reduction Act's Climate Pollution Reduction Grants (CPRG) to fund clean transportation. It specifically recommends incorporating e-bike subsidies and targeted electric vehicle (EV) incentives for 'superusers' into Priority Climate Action Plans (PCAPs) to maximize competitiveness for EPA funding based on equity and emissions reduction metrics.

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 guide by RMI provides recommendations for recipients of the US EPA's Climate Pollution Reduction Grant (CPRG) planning grants to incorporate organic waste and landfill methane strategies into their Priority Climate Action Plans (PCAPs). It emphasizes the use of 20-year global warming potentials to highlight the urgency of methane reduction and suggests a combination of upstream waste prevention and downstream landfill control measures to achieve significant greenhouse gas reductions and community benefits.

This guide by RMI explains the role of Environmental Product Declarations (EPDs) as 'nutrition labels' for building materials, detailing how they report life-cycle assessment (LCA) data to track embodied carbon. It outlines the current limitations of EPD standardization and proposes a vision for 'ideal' EPDs based on rigorous Product Category Rules (PCRs) to ensure fair and competitive carbon reduction policies.

This report by the World Resources Institute (WRI) analyzes the adoption of electric school buses (ESBs) in the United States as of June 2023. It tracks the number of committed vehicles, the impact of federal and state funding, and the distribution of these buses across different demographics and environmental conditions, highlighting a trend toward more equitable deployment in low-income and high-pollution areas.

This report by RMI analyzes how updated energy efficiency standards and Inflation Reduction Act (IRA) tax incentives can reduce energy costs for low-income Americans by encouraging the construction of high-efficiency, all-electric homes.

This guide by RMI explores how Real Estate Investment Trusts (REITs) can leverage their extensive rooftop and parking assets to drive solar development, reducing greenhouse gas emissions while increasing shareholder value. It identifies significant untapped capacity, outlines the financial and regulatory barriers to adoption, and proposes community solar as a viable solution to overcome these challenges.

This fact sheet explains the Advanced Clean Truck (ACT) regulation adopted by California in 2020, which requires original equipment manufacturers (OEMs) of medium- and heavy-duty vehicles to increase the percentage of zero-emissions vehicles (ZEVs) and near-zero-emissions vehicles (NZEVs) in their annual sales from 2024 to 2035.
