In 2024, WRI supported over 150 U.S. cities and counties in accelerating clean energy deployment and helped over 60 cities claim more than $12 million in tax credits via the Inflation Reduction Act's elective pay mechanism. The organization advanced next-generation geothermal technologies, launched a database of 50 community benefits frameworks for transmission projects, and supported the deployment of electric school buses (ESBs) through initiatives like the RVXDS project in California. WRI also focused on reforming power markets and grids, providing technical assistance to the PJM Cities and Communities Coalition and researching interregional transmission procurement.

An analysis of 2020 Residential Energy Consumption Survey data reveals that extremely low-income US households—those earning less than 30% of the state median income—face a disproportionately high average energy burden of 14%, exceeding the 10% threshold for energy poverty. The report highlights that the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act could save American families approximately $38 billion on electricity bills through technology upgrades and rebates. It identifies successful state-level interventions, such as California's percentage of income payment plans (PIPPs) and Colorado's low-income community solar programs, as models for alleviating energy poverty. The analysis further notes that extremely low-income households in southern states experience the highest energy burdens, often correlating with higher income inequality and diversity indices. The document concludes that states can simultaneously pursue decarbonization and energy affordability, citing Colorado and Washington as examples of states integrating specific energy affordability policies into their climate targets.

The Clean Air Task Force (CATF) advocates for the adoption of three specific accounting standards—new supply, hourly matching, and deliverability—for the Section 45V Clean Hydrogen Production Tax Credit. CATF warns that without these 'Three Pillars,' electrolytic hydrogen could result in consequential emissions twice as high as conventional 'gray' hydrogen by diverting clean power from the grid and forcing a reliance on fossil fuel generation. While the organization suggests these strict standards are essential for long-term deployment funding under 45V and EPA rules, it notes they may be less critical for short-term demonstration programs like the Regional Clean Hydrogen Hubs Program.

The briefing outlines how state energy offices can maximize the impact of the Inflation Reduction Act by enabling the 'stacking' of federal, state, and utility incentives for whole-home retrofits. It identifies key barriers to this process—such as a lack of public guidance, inconsistent program requirements, and excessive application processes—and suggests solutions like standardized eligibility and consolidated applications. Additionally, it encourages states to use flexible funding sources to cover gaps not fully addressed by the IRA, specifically health and safety repairs, cold climate heat pumps, and electrical upgrades.

Environmental organizations are urging the Indiana Department of Environmental Management (IDEM) to intensify enforcement at the Merom Generating Station in Sullivan County. Originally slated for retirement in 2023, the coal-fired plant was sold to Hallador Power Co., LLC and is now expected to operate indefinitely, partly to meet the high energy demands of a cryptocurrency mining operation run by AboutBit, LLC. The letter details a history of permit violations, including illegal levels of ammonia and iron in wastewater, excessive air opacity, and groundwater contamination from coal ash landfills. The authors argue that the plant's continued operation poses significant health risks and call for stricter monitoring, compliance plans, and fines.

The EU aims to import 10 million tons of renewable hydrogen by 2030 to decarbonize heavy industry and transport, as domestic production is expected to fall short of demand. The report identifies the US Gulf Coast, Australia, and other regions with low renewable energy costs as key potential suppliers. To activate this trade, the EU needs to invest in port infrastructure (ammonia terminals and crackers), clarify certification schemes, and provide €15 billion to €20 billion in public support to offset green premiums over blue hydrogen. While Northwest Europe will rely heavily on imports, Southern Europe (Spain and Portugal) is expected to become more self-sufficient by the mid-2030s.

The report examines the potential for international cooperation to mitigate the risks of unilateral border carbon adjustments (BCAs), such as 'green protectionism' and trade retaliation. It evaluates the G7 Climate Club, GASSA, and the OECD's IFCMA using a framework of 'input legitimacy' (inclusiveness and institutional strength) and 'output legitimacy' (effectiveness in achieving five specific goals). The analysis finds that while none are currently ideal for BCA cooperation, the IFCMA shows the most promise due to its focus on data and comparability. The report warns that domestic political priorities and existing policy path dependencies, such as the EU's established CBAM, hinder the creation of a unified international approach.

The report identifies significant barriers to 'stacking' (combining) multiple financial incentives for US residential energy retrofits, including complex application processes, inconsistent performance standards, and funding gaps for health and safety repairs. It analyzes the interaction between Inflation Reduction Act (IRA) tax credits and rebates, noting that while clean energy retrofits can be more affordable than fossil fuel alternatives after incentives, low-income households often lack the 'tax appetite' to benefit from tax credits. RMI recommends that state program administrators prioritize funding for pre-electrification upgrades, consolidate application processes, and increase allocations for underserved communities and multi-family housing.

A survey of 906 registered U.S. voters in October 2023 reveals broad support for clean energy infrastructure and the Inflation Reduction Act, though significant political polarization persists. While majorities support carbon taxes and transitioning to 100% clean energy by 2050, trust in fossil fuel companies remains low, and actual political or consumer activism is limited despite expressed willingness to act.

The 2023 update finds that while current policies for 25 major economies may result in 2030 emissions between -6% and +8% compared to 2019 levels, this falls short of the 43% reduction aligned with the Paris Agreement. While 13 countries are now on track to meet their NDC targets, 12 countries still face an implementation gap.

The document analyzes how New York and California are reforming their permitting processes to overcome delays in clean energy deployment, highlighting the use of 'one-stop shops', legal deadlines, and community benefit agreements. While these reforms aim to improve financial viability and public support, the study identifies risks such as imprecise legal language, potential infringement on Indigenous rights, and persistent bottlenecks in grid interconnection that require federal intervention.

A letter from a multidisciplinary group of scientists to President Biden calling for a fast and fair phaseout of all fossil fuels, increased climate finance for low- and middle-income countries, the operationalization of the Loss and Damage Fund, and the protection of COP28 negotiations from fossil fuel industry interference.

The report asserts that the EPA's proposed rules for coal and gas power plants are technically feasible and will not threaten resource adequacy or operational reliability. It synthesizes six industry-standard studies showing that the U.S. grid can remain stable even if all unabated coal is retired by 2035. The authors argue that reliability risks are institutional rather than technical, stemming from slow interconnection processes and inadequate transmission planning. To manage the transition, the report recommends adopting 'connect-and-manage' interconnection processes, deploying grid-enhancing technologies, and proactively planning transmission for coal retirements.

Financial institutions (FIs) can leverage tools like RMI's Oil Climate Index plus Gas (OCI+) and satellite data to pinpoint methane 'hot spots' in oil and gas portfolios. Methane accounts for approximately half of the industry's Scope 1 and 2 emissions, yet emissions intensities vary by a factor of 10 or more between equivalent assets. The report highlights that 40% of needed methane reductions could be achieved through cost-neutral or net-profitable investments, such as leak detection and repair. With new regulations like the US Inflation Reduction Act's methane fee, FIs are encouraged to use this data to manage transition risks, set accurate disclosure targets, and steer client engagement toward immediate decarbonization opportunities.

The document details the technical methodology used by the Union of Concerned Scientists to model US energy system transitions. It outlines targets for reducing energy and industrial CO2 emissions by 47.5% by 2030 and 100% by 2050, alongside specific targets for non-CO2 gases. The analysis employs seven scenarios, including reference cases and various net-zero pathways, incorporating the impacts of the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA). Key assumptions include the total retirement of coal generation by 2030 in net-zero scenarios and 100% zero emissions vehicle sales by 2035.

The Union of Concerned Scientists (UCS) analysis concludes that the United States can meet its climate goals through a rapid phase-out of fossil fuels and a transition to clean energy, which would yield significant economic and public health benefits. While the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) provide critical momentum, the report finds that the U.S. will fall short of its 2030 goals without additional robust policies. The most effective near-term strategy is the decarbonization of the power sector via wind and solar, while long-term reductions depend on the electrification of transportation, buildings, and industry. The report emphasizes that reducing overall energy demand can lower the required scale of new infrastructure and that a just transition must prioritize marginalized communities and hold fossil fuel companies accountable.

The Union of Concerned Scientists (UCS) analysis finds that while the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) accelerate emissions reductions, additional policies are required to meet US climate targets. Achieving net-zero by 2050 requires a rapid phaseout of fossil fuels, a massive scale-up of wind, solar, and energy storage, and expanded electrification and energy efficiency. The report argues that the health and climate benefits of this transition—including avoided premature deaths and reduced climate-caused damage—significantly outweigh the energy system costs.

The report evaluates hydrogen fuel-cell electric vehicles (FCEVs) and hydrogen combustion engines for heavy-duty freight. It finds that while FCEVs offer range and weight advantages, they are significantly less energy-efficient than battery-electric vehicles (BEVs) and suffer from high fuel costs. The document highlights that most hydrogen is currently produced from natural gas, leading to life-cycle emissions similar to diesel trucks, and warns that hydrogen combustion engines still emit harmful air pollutants. Consequently, the author concludes that FCEVs will likely remain niche solutions for specific long-haul applications where BEVs are infeasible.

The Episcopal Southern Ohio Diocese established the Energy Efficiency Grant and Loan Program in July 2021 to fund energy-saving retrofits in its congregations. The program requires participants to conduct ASHRAE Level 2 energy audits and develop reduction plans to qualify for grants of up to $10,000 or low-interest loans of up to $10,000. By June 2023, the program awarded $533,047 through 56 grants and disbursed $121,207 in loans. Case studies of churches in Athens, Circleville, and Washington Court House demonstrate the adoption of LED lighting, high-efficiency furnaces, and ductless mini-split heat pumps to lower carbon emissions and operational costs. The document also notes that the Inflation Reduction Act's "direct pay" incentives may now encourage these nonprofits to pursue solar installations after first improving building efficiency.

The policy brief highlights a systemic gap between self-reported methane emissions in the US oil and gas sector and actual emissions measured via remote sensing. It argues that current EPA Greenhouse Gas Reporting Program (GHGRP) guidelines rely on simplistic assumptions that miss 'super-emitting' events, leading to underestimations of emissions by factors of two to four. This data gap threatens the efficacy of the Inflation Reduction Act's (IRA) Waste Emissions Charge, potentially resulting in hundreds of millions of dollars in lost fees. The author calls for the integration of empirical data and updated reporting categories to improve transparency, incentivize mitigation, and ensure accurate pricing of methane emissions.
