The report examines the 'water-energy nexus' in the western United States, specifically the eleven states of the Western Electric Coordinating Council (WECC). It models eight scenarios from 2008 to 2100, varying by carbon emission goals, water conservation mandates, and energy efficiency levels. The primary finding is that while power plants require water, their total consumption is small compared to agricultural and urban use, making the water-energy nexus a secondary concern in the region's broader water crisis. The analysis suggests that carbon pricing (around $70 per ton) is a more likely driver for shifting energy strategies than water pricing, as water prices would need to exceed $4,000 to $7,000 per acre-foot to make water-conserving energy scenarios the least-cost option.

The U.S. Southwest is currently relying on unsustainable groundwater extraction to meet water demands. Climate change is projected to exacerbate this crisis by increasing agricultural water needs and shifting snowmelt timing, leading to significant water shortfalls. The report finds that without adaptation, the region faces a cumulative water shortfall of up to 2,253 million acre feet over the next century under a severe climate scenario (A2). While desalination and imports are deemed non-viable due to cost and availability, planned reductions in urban and agricultural water use—particularly the elimination of low-value crops—could bring water use to sustainable levels. The economic cost of inaction is estimated between $2.3 trillion and $5 trillion over the next century.

The California Water Supply and Demand Model (CWSD) assesses how climate change affects water availability and usage in California, focusing on the energy, urban, and agricultural sectors. The model evaluates scenarios with no adaptation, slow adaptation, and fast adaptation across different climate projections (B1 and A2). Key findings indicate that without adaptation, agricultural water demand will rise due to higher temperatures, particularly in the San Joaquin Valley. While slow adaptation may only marginally reduce use, fast adaptation—driven by higher water prices and technological efficiency—could significantly decrease demand. The report also extends its agricultural analysis to other Western U.S. states, noting a general increase in water demand by 2100.

The paper analyses 60,463 electricity-related energy efficiency recommendations for U.S. manufacturing SMEs, finding that payback time and investment costs are the primary drivers of implementation. It identifies an 'energy efficiency paradox' where firms are more sensitive to upfront costs than long-term savings, and notes that implementation rates are higher in states with higher greenhouse gas emissions and lower industrial GDP.

Tennessee spent a net $1.21 billion on imported coal in 2008, importing over 99 percent of the coal used by its power plants. The Tennessee Valley Authority (TVA) is the primary purchaser of these imports, with the Cumberland plant identified as the state's most import-dependent facility. To reduce this economic drain, the document suggests adopting an energy efficiency resource standard and a renewable electricity standard, noting that wind, solar, small-scale hydropower, and biomass could technically meet up to 60 percent of the state's 2008 power demand.

The Bureau of Land Management (BLM) successfully influenced the U.S. Fish and Wildlife Service (FWS) to withdraw a 2006 proposal to list Graham's penstemon, a rare wildflower found in Utah and Colorado, as a threatened species. Internal documents reveal the BLM formed a "strike team" specifically to prevent this listing to facilitate oil and gas and oil shale development. The BLM provided misleading data regarding the plant's habitat slopes and falsely claimed no overlap between the species' habitat and potential oil shale development zones. Despite these assurances, a 2008 Programmatic Environmental Impact Statement (PEIS) opened over 90 percent of the proposed critical habitat for commercial oil shale leasing. Conservation groups subsequently sued the FWS in 2008, alleging the agency ignored scientific evidence and relied on unproven BLM conservation measures.

The document identifies approximately 2 million mobile homes built before 1976 as the "worst housing stock" in the U.S., noting they are energy-inefficient and often house low-income, elderly, or disabled residents. It highlights that these structures are often ineligible for traditional weatherization programs and proposes the Energy Efficient Manufactured Housing Act of 2009 to provide rebates for ENERGY STAR qualified homes. The text details the differences between mobile, manufactured, and modular homes, and provides demographic data on residents of pre-1980 manufactured housing.

The report argues that RGGI's design, which caps emissions only for power plants within participating states, creates a price advantage for imported electricity from coal-heavy states like West Virginia and Pennsylvania. This 'leakage' is exacerbated by excess capacity in existing coal plants and planned transmission upgrades that facilitate power flow from west to east. The authors suggest that RGGI states should implement retail-level carbon caps, prohibit contracts with high-emission plants, and prioritize transmission projects aligned with climate goals to prevent the expansion of coal-based power.

The document highlights the role of school buses in reducing overall transportation emissions compared to private vehicles, while warning that diesel engine idling consumes significant fuel and poses severe health risks to children. It promotes an idle reduction curriculum developed by the Utah Clean Cities program to mitigate these impacts.

Earthjustice intervened in a legal settlement between the Bush administration and the state of Utah to ensure the Bureau of Land Management (BLM) retained the authority to protect wilderness-quality lands in Utah, preventing them from being permanently opened to development.

In April 2004, air quality modelers from nine EPA regional offices protested a policy change allowing states to select their own baseline years for measuring pollution in 'Class I' areas. This policy emerged from a compromise with North Dakota, which had been out of compliance with the Clean Air Act regarding Theodore Roosevelt National Park, hindering plans for new coal-fired power plants. EPA scientists argued the change 'artificially inflate[s]' baselines to mask policy changes and feared it would set a national precedent, as other states like Colorado, Montana, South Dakota, Utah, and Wyoming sought to follow suit.

The report examines the significant water demands of fossil fuel power plants in the Interior West, highlighting the environmental risks of cooling systems and the potential for water savings through dry cooling, energy efficiency, and renewables.

The Clean Air Task Force highlights six counties in the Southwest—Mesa and Weld in Colorado, Summit and Iron in Utah, Mineral in Nevada, and Maricopa in Arizona—that have implemented outstanding solar ordinances. These ordinances are noted for balancing growth with protections, streamlining permitting for federal lands, and clarifying project scale through acreage thresholds rather than production capacity.

The Utah FORGE project, a partnership between the University of Utah and the U.S. Department of Energy, utilized a diverse range of outreach tactics to establish community trust and transparency in rural Beaver County. Strategies included early consultation with local officials, educational programs for youth, and the installation of real-time seismic and water usage monitoring in public libraries to address environmental concerns. The document argues that leveraging trusted local institutions and creative engagement—such as song contests and science modules—can facilitate the success of geothermal projects and pave the way for subsequent commercial developments like Fervo Energy's Cape Station project.

The document outlines three primary geothermal heat extraction methods: conventional hydrothermal systems, Enhanced Geothermal Systems (EGS), and Closed Loop/Advanced Geothermal Systems (AGS). It clarifies that Superhot Rock (SHR) is a resource characterized by temperatures at or above the supercritical temperature of water (374°C for de-ionized water), which can be accessed using either EGS or AGS methods.

The report finds that Native American communities are more likely to live within a half-mile of oil and gas facilities than the general population of their encompassing states, leading to disproportionate exposure to methane, volatile organic compounds, and toxic air pollutants. This impact is exacerbated by high poverty rates and lack of health insurance, which limit housing options and access to medical care for conditions like asthma. Specifically, the analysis highlights the Navajo Nation, the Northern Ute (Uintah-Ouray), and the Fort Berthold Indian Reservation as areas of significant risk.

The document outlines the potential of superhot rock geothermal energy in Utah, noting that just 1% of the state's resource could provide 327 GW of energy capacity. It argues that this technology offers a low land-use footprint and a transition pathway for oil and gas workers.

Utah generates 2.3 million tons of coal ash annually, ranking 18th in the United States. The state utilizes a mix of landfills and ponds for disposal, with several sites lacking liners, leachate collection, or groundwater monitoring. The Intermountain Power Project operates six ponds with a combined capacity of 2.3 billion gallons, most of which are rated as low hazard.

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.
