This report by the World Resources Institute (WRI) analyzes the adoption of electric school buses (ESBs) in the United States as of March 31, 2022. It tracks 'committed' buses—those awarded funding, ordered, delivered, or in operation—highlighting a significant increase in commitments driven by large-scale contracts and specific funding sources like the Volkswagen Settlement. The report also examines the distribution of these buses across different demographics and pollution levels to assess the equity of the transition.

The 'US Stimulus Strategy' report by the Rocky Mountain Institute (RMI) provides four primary policy recommendations for a zero-carbon economic recovery in the United States following the COVID-19 pandemic. The strategy focuses on decarbonizing buildings and transportation, implementing debt forgiveness tied to emissions reductions, and establishing a federal Economic Recovery Facility to finance clean energy projects.

This policy brief argues that New York can meet its energy needs in New York City and Long Island through customer-focused solutions—energy efficiency, electrification, and demand response—rather than constructing the proposed $1 billion Northeast Supply Enhancement Project (NESE) gas pipeline. The author contends that the pipeline is incompatible with the state's Climate Leadership and Community Protection Act (CLCPA) and that non-infrastructure alternatives are more cost-effective and beneficial for public health.

A fact sheet detailing a USD 13 million green municipal bond issued by the South Central Connecticut Regional Water Authority on February 7, 2019, to refinance the Great Hill Tunnel & Pipeline restoration project.

This fact sheet details a USD 38 million Asset-Backed Security (ABS) green bond issued by the Connecticut Green Bank on April 9, 2019, to finance the Residential Solar Investment Program (RSIP).

This fact sheet details a USD 38.6 million Solar Asset-Backed Security (ABS) bond issued by SHREC ABS 1 LLC on April 2, 2019, to support residential solar energy in Connecticut.

The Carbon-Free Regions Handbook: Finance is a guide for regional governments on organizing and delivering financial solutions to enable low-carbon transitions. It outlines strategies for increasing capital availability, overcoming up-front costs, creating market incentives, and reducing procurement costs for clean energy assets.

This fact sheet details a USD 104 million C-PACE ABS issued by CleanFund on July 31, 2018, which is the second C-PACE securitisation globally.

This insight brief by the Rocky Mountain Institute (RMI) argues that Residential Property Assessed Clean Energy (R-PACE) financing can accelerate the adoption of net-zero energy (NZE) new construction in the United States. By attaching financing to the property rather than the owner, R-PACE addresses key market barriers such as high up-front capital costs and the split incentive between builders and homebuyers.

This fact sheet describes the formation and goals of the United States Climate Alliance and other subnational efforts to uphold the 2016 Paris Agreement following the Trump Administration's decision to withdraw the United States from the accord.

This briefing by the Rocky Mountain Institute (RMI) analyzes the landscape of home energy financing in the United States, identifying barriers to scaling both traditional and nontraditional lending products. It argues that the ease of origination and the timing of home improvements are more significant drivers of consumer choice than interest rates or loan terms.

This briefing outlines the Climate Policy Initiative's (CPI) framework for evaluating the efficiency of public financial interventions, such as green banks, in supporting the transition to a low-carbon economy. It focuses on identifying financial barriers and determining the most effective risk-bearing mechanisms and implementing institutions to address them.

The Community Energy Resource Guide, published by the Rocky Mountain Institute (RMI) in December 2015, provides a comprehensive roadmap for U.S. communities to develop energy action plans. It outlines a collaborative planning process, methods for analyzing energy landscapes, and specific tactics across the buildings, electricity, transportation, and industry sectors to accelerate the adoption of renewable energy and energy efficiency.

This fact sheet by the Environmental and Energy Study Institute (EESI) surveys employment data for the renewable energy and energy efficiency sectors globally and within the United States. It compiles data from various sources, including the U.S. Department of Energy and the International Renewable Energy Agency (IRENA), noting that inconsistent research methodologies and job definitions make direct comparisons difficult.

This fact sheet provides an overview of fuel cell technology, detailing its operational mechanisms, various types, and its comparative advantages over internal combustion engines and batteries. It examines the technical and economic barriers to widespread adoption—specifically cost, hydrogen production, and infrastructure—while outlining current applications in portable, stationary, and transportation sectors. The document also analyzes the role of U.S. federal and state policies, including Department of Energy (DOE) initiatives and state-level incentives, in driving the commercialization and deployment of fuel cells.

This 2015 fact sheet by the Environmental and Energy Study Institute (EESI) compiles employment data for the renewable energy and energy efficiency sectors in the United States and globally. It highlights significant job growth in U.S. green building and solar sectors, while identifying China as the global leader in renewable energy employment. The report notes challenges in data consistency due to varying methodologies and the cessation of the U.S. Bureau of Labor Statistics' Green Careers program.

This report by the Center for International Environmental Law (CIEL) analyzes how the proposed Regulatory Cooperation chapter of the Trans-Atlantic Trade and Investment Partnership (TTIP) agreement could undermine the authority of US states to implement public health and environmental protections. The author argues that the agreement's goals of regulatory convergence and compatibility would effectively create a regulatory ceiling, preventing states from adopting standards more protective than federal minimums, particularly regarding toxic chemicals and pesticides.

This fact sheet from the Environmental and Energy Study Institute describes combined heat and power (CHP) technology, which integrates the production of heat and electric power into a single process to increase energy efficiency and reliability. It details the current state of CHP in the United States, its economic and environmental benefits, its role in disaster resilience, and the policy barriers and goals associated with its expansion.

This fact sheet from the Environmental and Energy Study Institute (EESI) describes the technology, benefits, and potential of Combined Heat and Power (CHP) systems in the United States. It highlights how CHP increases energy efficiency, reduces emissions, and provides resilient power during grid failures, while identifying regulatory barriers and the specific advantages of biomass-fueled systems.

The City of Boulder Climate Action Plan Analysis Report, prepared by the Rocky Mountain Institute (RMI) in May 2012, evaluates the cost-effectiveness and emissions impact of 19 demand-side management programs funded by the Climate Action Plan (CAP) tax. The analysis finds that while Boulder has achieved significant energy savings, it will not meet its 2012 Kyoto Protocol-based emissions reduction targets through current programs alone. RMI recommends transitioning toward more comprehensive, integrated, and long-term energy efficiency strategies and suggests that municipalization of the energy supply could significantly enhance the city's ability to reach its goals.
