The document outlines a three-phase framework for states to maximize federal clean energy funding: Identification, Collaboration, and Implementation. It details a wide array of available federal grants, loans, and tax credits across generation, transmission, energy efficiency, and workforce development, emphasizing the role of the DOE, EPA, and USDA in supporting the transition to a clean power system.

The industrial sector is projected to be the highest emitting sector in the U.S. by 2030, accounting for 23% of greenhouse gas emissions (or 30% including electricity). While the Inflation Reduction Act, Bipartisan Infrastructure Law, and CHIPS and Science Act provided significant initial investment, the U.S. Department of Energy estimates that $700 billion to $1.1 trillion is needed to decarbonize the sector by 2050. This investment requirement is 5 to 10 times greater than the funding provided by the BIL and IRA, with 60% of necessary technologies still under development or not yet created. To address this gap, the document proposes a combination of tax credits, subsidies, and grants to reduce emissions intensity, demand-side levers to create markets for low-carbon products, and market-based mechanisms to disincentivize emissions-intensive processes.

Zero Carbon Analytics finds that Japanese households with rooftop solar panels would have saved nearly 135% compared to those without in FY 2020, resulting in a net benefit of JPY 37,422 (USD 353). The report argues that Japan, which has the lowest clean energy share among G7 countries, can accelerate its energy transition by leveraging rooftop solar to overcome mountainous terrain constraints. It highlights the role of policy incentives like feed-in-tariffs (FiT) and tax credits in driving adoption in the US, EU, and UK, and suggests that Japan needs low-cost finance to reduce upfront costs and avoid diverting support toward unproven technologies like hydrogen.

The report emphasizes that US states are currently underutilizing federal clean energy incentives, particularly tax credits, and suggests that states adopt administrative programs, demand-pull policies, and stacking analyses to capture this investment potential. It notes that while residential tax credit usage is higher than predicted, most states are not on track to reach their full investment potential by 2030. The analysis, which covers the lower 48 US states, utilizes updated data from the JCT and CBO to estimate sector-specific funding opportunities.

The document argues that Section 45Z should prioritize low-carbon aviation fuels and avoid over-subsidizing biofuels with high indirect emissions. It recommends modifying the GREET model to align with CORSIA standards for indirect land use change (ILUC) and cautions against using negative emissions values or fugitive methane from oil and gas as feedstocks. Additionally, it advocates for the eligibility of synthetic sustainable aviation fuel (SAF) and the independent application of tax credits across the fuel value chain.

The Power Decarbonization Funding Tracker lists various US federal incentives for power sector decarbonization. It categorizes funding into three sectors: Transmission and Electric Grid, which includes the $10.5 billion Grid Resilience and Innovation Partnerships (GRIP) program and the $2.5 billion Transmission Facilitation Program; Clean Firm, featuring the $6 billion Civil Nuclear Credit Program and $2.5 billion for the Advanced Reactor Demonstration Program; and Rural Electrification, highlighted by the $9.7 billion Empowering Rural America (New ERA) Program and the $2.025 billion Rural Energy for America Program (REAP). Additionally, it identifies key tax credits for clean electricity production, investment, and carbon sequestration.

The Clean Air Task Force proposes a two-step method for section 45V tax credits to prevent producers from losing top-tier credits due to brief periods of grid electricity use during maintenance or supply disruptions.

The policy brief contends that fixed upstream emission rates for methane and CO2 in the 45VH2-GREET model create economic distortions by penalizing low-emission hydrogen producers and rewarding those with higher-emission supply chains. It proposes replacing these fixed rates with project-specific data from the EPA's Greenhouse Gas Reporting Program (GHGRP) to ensure tax credits align with actual lifecycle emissions.

The briefing examines the role of carbon capture and storage (CCS), noting that the majority of the world's 41 operational projects are linked to the oil and gas industry, specifically for enhanced oil recovery (EOR). It highlights a history of 'unmet expectations' and slow deployment, with capture rates often falling short of targets. While CCS is proposed for hard-to-abate sectors like cement and steel, the document argues it is often less cost-effective than electrification or energy efficiency. It further details how CCS projects in Norway, Canada, and Australia have been used to maintain the financial viability of fossil fuel extraction.

The document details the financial scale of U.S. fossil fuel subsidies, noting a shift from net revenue to net loss for the government between FY 2016 and FY 2022. It analyzes the Biden-Harris Administration's FY 2024 budget proposal to eliminate 13 tax preferences to save $96.9 billion, while also highlighting how the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) continue to provide funding for methane reduction and carbon capture technologies.

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.

The document explores community ownership of clean energy infrastructure as a means to address socio-political and techno-economic barriers to deployment. It details various ownership models used in the US and Europe, including LLC direct ownership, partnership 'flips', and cooperatives, while highlighting the potential impact of the US Inflation Reduction Act's transferability and direct pay provisions.

REITs in the US control approximately 38.5 billion sq. ft. of solar-appropriate surface area, capable of generating over 25 percent of electricity used in US commercial buildings. While on-site solar is economically viable for 90 percent of the top 50 REITs by 2025, adoption is hindered by tax credit complexities, IRS recapture rules, and risks associated with tenant turnover and low energy intensity in industrial warehouses. Community solar is proposed as a solution to these barriers, offering additional tax credit bonuses of 10–20 percent when serving low- and moderate-income residents. Currently, only nine US states support rooftop community solar, though some leading REITs like Prologis, Lineage Logistics, Blackstone, Brookfield, and Hartz Mountain have already installed significant capacity.

The guide outlines three federal funding pools for US clean industrial projects: the Office of Clean Energy Demonstration (OCED) providing grants up to 50% of costs for non-commercial technologies; the Loan Programs Office (LPO) offering up to $412 billion in loan authority to bridge projects to bankability; and various uncapped Section 45 tax credits for hydrogen, heavy industry, and carbon management. It emphasizes the role of these incentives in enabling the creation of 'clean industrial hubs' and the necessity of coordinating federal, state, and private capital to realize these projects.

The policy brief examines four international models of clean growth financing to provide lessons for Canada's transition to carbon neutrality by 2050. It highlights Australia's Clean Energy Finance Corporation for its dual focus on profitability and emissions reduction, the UK's contracts for difference for effective risk-sharing in renewable energy, Norway's Longship project for its holistic state support of carbon capture and storage, and the US Inflation Reduction Act's use of tax credits tied to carbon intensity and social standards for hydrogen production.

The document argues that the EIA's Annual Energy Outlook (AEO) underestimates the impact of the Inflation Reduction Act (IRA) compared to Energy Innovation's modeling and other third-party analyses. While the AEO projects a 31% reduction in energy-related CO2 emissions by 2030 relative to 2005 levels, Energy Innovation's analysis finds a 41% reduction. The primary drivers of this discrepancy are the AEO's more conservative estimates of clean energy deployment in the electricity sector and electric vehicle sales, as well as its narrower scope, which focuses only on tax credits and excludes various budget-based government programs and non-CO2 greenhouse gases.

RMI's analysis indicates that US states can secure significant federal investment, job growth, and health improvements by ambitiously adopting the Inflation Reduction Act's (IRA) tax credits, rebates, and grants. Under a "Climate Ambitious Scenario," states could see cumulative investments between $1 billion and $130 billion by 2030, with the highest per capita gains expected in states with strong renewable energy potential and industrial activity, such as Wyoming, Montana, and Louisiana.

The Bushnell Center for the Performing Arts implemented a series of energy efficiency projects, most notably replacing a 40-year-old boiler with a 92 percent efficient three-way steam system. This project was funded through a combination of a $250,000 state grant, a $16,000 utility rebate, and a $384,016 C-PACE loan. The theater also utilized the Connecticut Neighborhood Assistance Act Tax Credit Program to attract donor funding for LED lighting, air handling units, heat pumps, and roof insulation. These measures have resulted in annual energy savings of $60,000 and an annual reduction of 37.2 metric tons of carbon emissions.

The report finds that the IRA will significantly accelerate the adoption of electric vehicles (EVs) and zero-emission vehicles (ZEVs) in the US, potentially exceeding the Biden administration's 2030 targets. However, the authors argue that these incentives alone are insufficient to meet the US Nationally Determined Contribution or the Paris Agreement goals, necessitating additional federal GHG standards and investments in infrastructure and manufacturing.

The document analyzes the synergistic effect of the Energy Act of 2020, the Infrastructure Investment and Jobs Act of 2021, the Inflation Reduction Act of 2022, and the CHIPS and Science Act of 2022 on the U.S. energy transition.
