The Electric Utility Toolkit explains the technical and regulatory framework of the US power grid, highlighting systemic inequalities in energy access and affordability. It details the role of Public Utility Commissions (PUCs) and provides actionable steps for citizens to engage in the regulatory process to promote energy justice and decarbonization.

The Union of Concerned Scientists (UCS) recommends that Maine's offshore wind procurement process prioritize larger nameplate capacities to maximize grid reliability. Based on an analysis of winter seasons from 2000 to 2022, UCS found that offshore wind fleets of 1500 MW, 4000 MW, and 8000 MW could substantially reduce the number of days the New England grid faces elevated energy shortfall risk. The document argues that offshore wind is an ideal solution for winter reliability because its output typically increases during cold snaps, unlike fossil fuel supplies which are subject to global market volatility and import constraints.

The Union of Concerned Scientists analyzed US Senate lobbying disclosure reports from January 2019 to December 2023 to quantify corporate influence on the food and farm bill. The analysis found that giant agribusiness companies and industry associations spent over half a billion dollars during this period to influence legislation. The methodology involved searching the Senate database for the phrase "farm bill," cleaning duplicate data, accounting for report amendments and terminations, and categorizing entities into sectors such as Agribusiness, Fuel/Energy, and Pharmaceuticals to assess the scale of corporate profit prioritization in federal farm policy.

Between 2019 and 2023, agribusiness interests spent over $523 million lobbying on the US food and farm bill, with spending peaking in 2023. The report highlights the role of the American Farm Bureau Federation (AFBF) in opposing climate action and environmental regulations while advocating for commodity subsidies. It recommends that Congress prioritize small and marginalized farmers and strengthen antitrust enforcement to curb corporate power.

The Union of Concerned Scientists (UCS) expresses concern over the Atomic Energy Advancement Act (H.R. 6544), arguing that certain provisions threaten the independence of the Nuclear Regulatory Commission (NRC) and national security. The organization recommends rejecting language that would force the NRC to prioritize the efficiency and benefits of nuclear energy over radiological health and safety, rejecting mandates to 'maximize the efficiency' of oversight programs, and maintaining the prohibition on foreign ownership, control, or domination of U.S. nuclear facilities.

To meet its 2045 clean energy goals, California must roughly triple its energy capacity, but faces significant barriers in grid infrastructure, interconnection processes, and land use. The document proposes solutions such as grid-enhancing technologies, interconnection reforms with equity considerations, and incentivizing clean energy on built environments or disturbed lands.

The document outlines the GIS-based methodology used to assess the proximity of electricity generating units and substations to environmental justice (EJ) populations in Massachusetts. It details the data sources used, including S&P Global and utility plans, and explains the criteria for identifying EJ neighborhoods based on state law. The analysis specifically focused on utility-scale projects and proposed infrastructure to ensure that future siting decisions do not replicate past failures of overburdening vulnerable populations.

The analysis reveals that over 80% of existing polluting electricity generating units and nearly 70% of substations in Massachusetts are located in or near environmental justice (EJ) neighborhoods. It warns that current trends in proposed infrastructure, including a new fossil-fuel peaker plant and several substations, continue to overburden these communities. The authors recommend integrating cumulative impact assessments, expanding the Energy Facilities Siting Board to include EJ and Indigenous representation, and prioritizing public health and climate targets in siting decisions.

The document outlines the technical framework for assessing electric vehicle (EV) benefits, utilizing EPA eGRID data for power plant emissions and the GREET model for upstream feedstock emissions. It specifies the use of a sales-weighted EV efficiency of 0.314 kWh/mile and an average annual mileage of 11,599 miles. Public health benefits are derived from the American Lung Association's use of the EPA COBRA model, while economic data includes announced manufacturing jobs from the EV Jobs Hub and charging infrastructure growth from the Alternative Fuels Data Center. Fuel cost comparisons rely on NREL utility rates and GasBuddy gasoline prices.

The Union of Concerned Scientists provides a guide for voters to hold 2024 political candidates accountable across several key areas: clean energy and transportation, climate accountability, climate change resilience, food system reform, nuclear weapons policy and justice, and the protection of scientific integrity within federal agencies.

The document examines the vulnerability of the US gas-fired power plant fleet to extreme winter and summer weather, noting that gas plants are the primary source of generation failures during major storms. It argues that current resource adequacy metrics overvalue gas reliability and recommends transitioning to probabilistic modeling, increasing transparency, and prioritizing renewables, storage, and demand-side solutions to ensure a resilient power grid.

The document examines the reliability of natural gas power plants in the US, noting that they are disproportionately prone to failure during extreme weather, such as winter storms. It highlights the 2021 Winter Storm Uri as a critical example of how gas plant failures lead to catastrophic blackouts. To improve grid reliability and mitigate climate change, the author recommends transitioning to clean energy solutions—including renewables, energy storage, and demand-side efficiency—and urges regulators to restrict the approval of new gas plants.

The Union of Concerned Scientists defines a framework for Clean Fuel Standards (CFS) centered on oil industry accountability, full lifecycle emission assessments, and the protection of disadvantaged communities. The principles advocate for a rapid phase-out of petroleum in favor of renewable electricity and low-carbon fuels, while ensuring that feedstock consumption does not cause deforestation or food market disruptions. The framework emphasizes that a CFS must not create pollution "hot spots" and should complement, rather than replace, other pollution-reduction policies.

A coalition of organizations argues that the next U.S. farm bill must move beyond 'business-as-usual' to address the climate crisis, food insecurity, and systemic discrimination. The statement advocates for a comprehensive suite of bills designed to achieve net-zero agricultural emissions by 2040, expand SNAP access, protect farmworkers from heat and toxic pesticides, and curb the power of corporate agriculture.

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 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 document advocates for a prioritized approach to repurposing approximately 1 million acres of irrigated farmland in California to meet Sustainable Groundwater Management Act (SGMA) goals. It argues that 'extractive agriculture'—characterized as water-intensive and soil-degrading—imposes significant health and economic costs on rural disadvantaged communities that outweigh the revenues generated. The proposed framework prioritizes repurposing land inside these communities first, followed by land within a one-mile buffer, and finally other cropland through a transparent cost-benefit process. Proposed sustainable alternatives include renewable energy generation, habitat restoration, and regenerative agriculture.

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.
