The document asserts that natural gas is not a clean energy source, detailing how its production, transport, and combustion cause significant environmental degradation and health issues. It highlights the potency of methane leaks and the high carbon emissions from LNG and gas-to-power plants, particularly in the South African context. The author recommends a holistic lifecycle impact assessment to counter the misconception that gas is a viable strategy for reducing emissions.

The document provides an overview of nuclear energy as a low-carbon, high-capacity power source, detailing its current contribution to the U.S. electricity mix and the challenges facing its growth. It highlights the aging state of the U.S. nuclear fleet, the lack of a permanent radioactive waste disposal solution, and the high costs and delays associated with new construction. The brief also explores emerging technologies, such as Small Modular Reactors (SMRs) and Generation IV reactors, as potential paths to maintain nuclear power's role in a decarbonized economy.

Earthjustice argues that the American Coal Ash Association (ACAA) produced a 'junk science' report by ignoring critical groundwater exposure pathways, manipulating EPA screening levels for arsenic and chromium, and cherry-picking data from the U.S. Geological Survey (USGS) to make coal ash appear similar to common soil. The critique highlights that fly ash concentrations of chromium and arsenic can be thousands of times higher than groundwater protection screening levels and notes the ACAA's failure to address risks from particulate matter inhalation.

The document details the disposal of 2.1 million tons of annual coal ash in Wyoming, highlighting that 17 ponds across five plants exist, with three rated as "significant hazard." It notes that 11 ponds are over 30 years old and identifies specific historical releases and groundwater contamination issues at sites like the Naughton, Dave Johnston, and Jim Bridger power stations.

The document provides a detailed schedule of federal coal lease readjustment dates from 2021 to 2025, identifying the specific lease numbers, the states where the leases are located, and the companies holding those leases. The list covers operations across several Western U.S. states, including Wyoming, Montana, Utah, Colorado, New Mexico, North Dakota, Washington, and Oklahoma.

Earthjustice argues that the FWS proposal to delist gray wolves in the Northern Rockies is illegal and biologically unsound. The organization contends that the proposed DPS boundaries are arbitrary, demographic recovery goals are set too low to ensure long-term viability, and state regulatory frameworks in Idaho, Wyoming, and Montana are inadequate to protect wolves from aggressive killing. Furthermore, Earthjustice asserts that the FWS failed to account for habitat fragmentation from roading, the loss of historic range, and the lack of guaranteed funding for management activities.

A group of over 30 law professors argues that the public trust doctrine (PTD) is an inherent attribute of state sovereignty that obligates Utah to protect the Great Salt Lake. The brief contends that Utah has violated this duty by failing to restrain upper basin water diversions, which have reduced the lake's footprint by half and threatened species extinction. The authors assert that the PTD applies not only to navigable waters but also to non-navigable tributaries and groundwater that sustain the lake, citing legal precedents from other Western states like California, Nevada, and Hawaii.

The document outlines the economic and environmental benefits of energy efficiency in Wyoming, specifically highlighting how an annual energy savings target of 1.5%, national model building codes, and 40 MWs of new combined heat and power could avoid 2.6 million tons of CO2 and save residents over $2 billion by 2030.

The document consists of a collection of 45 figures mapping the FSEIS routes for nuclear waste transport through nearly every U.S. state and the District of Columbia.

The report argues that Apollo Global Management's private equity model—characterized by high leverage and cost-cutting—has harmed patients and workers across its 220 hospitals. It documents specific instances of service cuts, poor quality ratings, and regulatory failures, while questioning the anti-competitive nature of the Lifepoint-ScionHealth spinoff.

The document details Tri-State's Responsible Energy Plan (REP), announced in January 2020, which aims to retire significant coal capacity and add over 1 GW of wind and solar power by 2024. It outlines the economic and policy drivers behind the shift, the use of a multi-stakeholder advisory group to build credibility, and the challenges associated with stranded assets, transmission development, and the lack of a regional transmission organization in the West. The plan targets a 100% clean energy portfolio for Colorado by 2040 and a 70% reduction in emissions from Colorado wholesale electric sales by 2030.

The VPP Flipbook outlines how utilities can aggregate distributed energy resources (DERs)—such as batteries, electric vehicles, and smart thermostats—to provide grid services like capacity, energy, and resilience. It details a six-step development process and provides specific examples from utilities including PG&E, National Grid, and Green Mountain Power. The document emphasizes the importance of open-access structures, third-party partnerships, and the integration of VPPs into long-term resource planning to address load growth and decarbonization goals.

The Union of Concerned Scientists analyzes a proposal to increase Illinois's RPS to 35% by 2030 and its EEPS to a 20% reduction in electricity demand by 2025. Using the DOE's ReEDS model, the report finds that these strengthened standards would drive $23 billion in clean energy investment, save consumers $12.1 billion in electricity expenditures through 2030, and reduce carbon dioxide emissions by 9.3% compared to a scenario with no policies.

The document argues that the Sentinel ICBM program is prohibitively expensive, increases the risk of nuclear war due to high-alert postures, and is unnecessary given the existing submarine-launched ballistic missile capability.

The report provides a state-by-state breakdown of progress toward 2020 Clean Power Plan benchmarks, noting that some states have exceeded 500% of their goals while others show 0% progress. It highlights the role of energy efficiency, renewable energy standards, and regional initiatives in achieving these targets.

The Great Plains region has experienced increasing average temperatures and shifting precipitation patterns, with winter temperatures in northern states rising by more than 6°F over the last 30 years. Climate change is projected to exacerbate the depletion of the High Plains (Ogallala) aquifer, particularly in the southern region where unsustainable water use and extreme heat are already prevalent. Agriculture and livestock are highly vulnerable; rising temperatures are expected to shift crop zones, increase pest prevalence, and reduce livestock yields, with a projected 10% decline in cow/calf and dairy operations under higher emissions scenarios. Ecosystems, specifically prairie potholes and playa lakes, face threats from altered evaporation and recharge rates, which impacts migratory birds and aquifer replenishment. The document also highlights the vulnerability of 65 Native American tribes on rural lands facing water quantity and quality issues.

The document details the creation of a dataset identifying 11,309 school bus depots in the U.S. using remote sensing and aerial imagery from the National Agriculture Imagery Program (NAIP). The dataset is intended to support environmental justice analysis regarding air pollution hotspots in underserved communities, as well as electricity grid planning for school bus electrification and climate hazard risk assessment. Findings show that 51% of depots are located within 350 meters of a school, with North Carolina having the highest number of depots (841).

The document explains how wolves act as 'climate heroes' by regulating prey populations, which allows vegetation to recover and enhances carbon sequestration. Using Yellowstone National Park as a primary example, it describes how the reintroduction of wolves led to a resurgence of woody plants and beavers, improving wetland health. It also addresses the social conflicts between wolf conservation and rural communities, advocating for coexistence programs and science-based policies like the Endangered Species Act to protect these ecosystems.

The Great Plains, a temperate grassland system spanning from Canada to Mexico, supports thousands of plant and animal species but faces threats from agriculture, resource extraction, and invasive species. WWF is implementing conservation strategies for keystone and endangered species, including bison, black-footed ferrets, and prairie dogs, while working with Native Nations and ranchers to restore native grasslands and improve migration corridors for animals like the pronghorn.
