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 guide by RMI outlines ten strategies for United States cities to advance inclusive electric mobility, focusing on affordability and accessibility for residents without private vehicles or home charging. It provides specific examples of municipal policies, from building code mandates for EV-readiness in Arizona to zero-emission delivery zones in California, to help cities navigate budget constraints and reduced federal funding.

This report by RMI examines how flexible service connections (FSCs) can accelerate the deployment of electric truck charging infrastructure by allowing fleets to connect to the grid faster in exchange for limiting power draw during peak hours. Using modeling of utility feeder data from PG&E and National Grid, the report demonstrates that FSCs can significantly increase charging capacity and reduce the need for immediate, costly grid upgrades.

This policy brief by RMI argues that virtual power plants (VPPs)—aggregations of distributed energy resources like batteries and smart thermostats—have reached a scale capable of replacing traditional power plants but are not being adequately integrated into utility long-term planning. The document highlights that while VPPs are increasingly mentioned in regulatory filings, they are often not modeled as selectable resources on an equal footing with conventional generation, leading to a risk of inefficient grid overbuilding.

The Massachusetts Carbon Dioxide Removal Study, conducted by RMI for the Massachusetts Clean Energy Center (MassCEC), evaluates 23 carbon dioxide removal (CDR) and storage pathways to determine their feasibility and scalability within the state's policy and economic context to support its Net Zero 2050 mandate.

The US electric vehicle (EV) market is experiencing a slowdown in momentum due to federal policy shifts, including the expiration of purchase tax credits and the repeal of tailpipe emission limits. While EV sales fell 4% in 2025, charging infrastructure continues to expand through private investment. Automakers are pivoting away from all-electric targets toward a mix of hybrids and affordable models, while manufacturing investments in the Midwest and South have seen significant cancellations.

This research paper by the Institute for Security Studies examines two primary policy responses to climate change in Africa: carbon sequestration through forest regeneration and the implementation of a global carbon tax. It highlights the critical role of the Congo Basin as a carbon sink and analyzes four illustrative global carbon tax scenarios, concluding that a differentiated payment approach aligns best with international equity principles and the Paris Agreement.

This fact sheet by RMI analyzes data from over 200 performance incentive mechanisms (PIMs) in the United States to identify trends in how public utility commissions (PUCs) use these tools to drive priorities such as decarbonization, equity, and affordability.

This report by RMI examines how public utility commissions in Minnesota, Massachusetts, and New York use different cost allocation strategies during proactive distribution planning to balance grid investment needs with customer affordability during the electrification of buildings and transportation.

This report by the World Resources Institute examines the potential for U.S. states to lead the deployment of Direct Air Capture (DAC) technologies as federal funding and policy support for carbon dioxide removal (CDR) face rollbacks and uncertainty.

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 report by RMI analyzes the global trajectory of electric vehicle (EV) adoption, noting that many markets have passed critical tipping points. It highlights that in the United States, the total cost of ownership for light-duty EVs is now lower than for gas-powered cars, while medium- and heavy-duty (MHD) electric trucks are trending toward cost parity with diesel. The document also discusses the role of battery recycling in potentially eliminating the need for additional mining by 2040.

The E-Bike Rebate Program Guidebook, published by RMI, provides a comprehensive framework for local governments, nonprofits, and transportation agencies to design and implement e-bike rebate programs. It outlines a five-step process: establishing a project team and goals, designing funding and incentive structures, partnering with bike shops, executing community outreach, and managing the program launch and follow-up. The guide emphasizes equity, suggesting income-tiered rebates and diverse application methods to increase accessibility for low- and moderate-income residents.

This policy brief by RMI examines how US governors are addressing rising electricity costs, which have increased by an average of 23% over the last decade. The document highlights actions taken by governors in at least 14 states since 2023 to balance immediate customer relief with long-term system cost containment, while warning against superficial measures like one-time bill credits that do not address underlying affordability challenges.

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 RMI provides best practices for reforming energy efficiency incentive programs to accelerate the adoption of heat pumps. It argues that current programs are often too complex, deterring participation—particularly among low-to-moderate income (LMI) households—and recommends streamlining applications, aligning equipment specifications, and tailoring incentives to local climates to better support decarbonization goals.

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.

A report by the Center for International Environmental Law (CIEL) and Friends of the Earth US analyzing the risks and geographic scope of marine geoengineering technologies, arguing that these speculative interventions threaten all ocean basins and distract from fossil fuel phaseout.

This report by RMI discusses the challenges of decarbonizing existing buildings and outlines efforts in Massachusetts to create a viable regional market for equitable energy retrofits, specifically focusing on affordable housing and 'lighthouse projects' to serve as scalable models.
