The Union of Concerned Scientists reports that in 2012, the NRC oversaw 14 'near-misses'—events increasing core meltdown risk by at least 10-fold—at U.S. nuclear plants. The report argues that the NRC frequently fails to enforce existing regulations, such as allowing the Palisades Nuclear Plant to operate for nearly a month despite cooling water leaks that required shutdown within six hours. It also highlights a significant perception gap between NRC senior management and staff regarding the agency's internal safety culture, where half of the workforce reported negative reactions from supervisors after raising safety concerns.

In 2012, the U.S. Interior Secretary implemented a 20-year ban on new uranium mining claims across a million-acre area surrounding Grand Canyon National Park to protect the watershed, wildlife, and local communities, including the Havasupai Tribe. Earthjustice is intervening in consolidated lawsuits filed by the mining industry to overturn this ban. A U.S. District Judge in Arizona has already rejected industry claims that the Interior Department lacked the authority to ban claims on land parcels exceeding 5,000 acres.

The University of California, San Diego (UCSD) operates a microgrid that manages 42 megawatts of generating capacity, including solar photovoltaics, a cogeneration plant, and a landfill-gas fuel cell. This system allows the campus to optimize energy costs and 'island' from the main grid during emergencies, such as the September 2011 blackout affecting Southern California, Arizona, and Mexico.

The document argues that while the industrial sector is the largest energy consumer in the U.S. and relies heavily on fossil fuels for heat, solar thermal technology remains largely unexploited. It details three temperature ranges for industrial heat—low (below 80C), medium (80C to 250C), and high (over 250C)—and explains that low and medium ranges are already commercially viable for industries such as food, beverage, and textiles. Key barriers to adoption include high upfront costs, the variability of solar output, and the need for effective energy storage and process integration. The report notes that global capacity is dominated by China and Europe, while the U.S. lacks large-scale incentives specifically for industrial solar heating. Case studies from Arizona, New York, and Germany demonstrate the feasibility of using flat plate, parabolic trough, and vacuum tube collectors for pre-heating, cooling, and production processes.

The report finds that U.S. thermoelectric power plants withdrew between 60 billion and 170 billion gallons of freshwater daily in 2008, with coal plants accounting for the majority of this use. It identifies significant regional disparities in water intensity, noting that plants in the East generally withdraw more water due to a higher prevalence of once-through cooling. The analysis reveals that power plants contributed to water-supply stress in 20% of the 400 stressed watersheds identified. Furthermore, the report highlights critical gaps and inaccuracies in U.S. Energy Information Administration (EIA) data, including the total absence of reporting from the nuclear fleet. It argues that climate change and population growth will exacerbate these stresses, urging a shift toward low-water cooling technologies and low-carbon energy sources to ensure grid reliability and ecosystem health.

The report finds that U.S. power plants withdraw massive volumes of freshwater, with coal and nuclear plants being the most water-intensive. This demand contributes to water-supply stress in hundreds of watersheds and is exacerbated by droughts and heat waves. The authors highlight significant gaps and inaccuracies in EIA reporting and advocate for 'water-smart' energy choices, such as dry cooling and low-water renewables, to ensure energy reliability and water security.

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 EPA has introduced new GHG permitting standards under the Clean Air Act, requiring large power plants and refineries to undergo a Best Available Control Technology (BACT) analysis. While states typically issue these permits, the EPA has taken over this role in Arizona and Texas due to non-compliance. The program targets facilities adding more than 75,000 tons of CO2 (or equivalent) and will expand in July 2011 to include all new facilities emitting over 100,000 tons per year. The BACT process involves a five-step evaluation of technology availability, feasibility, effectiveness, and impact to determine the best emission control options.

The document presents data on the freshwater requirements of U.S. power plants, highlighting that coal and nuclear power are the primary consumers of freshwater for cooling. It details the distribution of cooling systems across the U.S. and identifies specific watersheds where power plant water use significantly impacts the Water Stress Index (WaSSI).

Concentrated solar power (CSP) uses mirrors to focus sunlight to generate electricity, primarily for utility-scale use. While the U.S. led in installed capacity as of 2009 with 429 MW, Spain followed with 182 MW. The technology varies from parabolic troughs and linear Fresnel reflectors to dish/engines and power towers. CSP is noted for its ability to provide power during peak late-afternoon demand and its potential for baseload generation via thermal storage or natural gas hybridization. Economic challenges include high initial construction costs, though operational costs are lower than fossil fuel plants. Policy mechanisms like feed-in tariffs in Spain and Israel, and investment tax credits in the U.S., are identified as key drivers for deployment.

The report argues that woody biomass is a low-carbon substitute for fossil fuels that can support forest health and rural economies if managed sustainably. It identifies high harvesting and transport costs, a lack of site-specific scientific data, and public distrust of federal land management as primary barriers. The author recommends technology-neutral energy incentives, the establishment of national environmental indicators, and the use of collaborative, multi-stakeholder frameworks to ensure biomass harvesting complements ecological restoration and biodiversity conservation.

The report examines the history and legal mechanisms used to construct barriers along the U.S.-Mexico border, specifically focusing on the 'Real ID Act' and 'Secure Fence Act'. It details how these laws allowed the Secretary of Homeland Security to waive nearly all federal and state laws, including environmental and historic preservation statutes, to expedite construction. The author highlights the resulting environmental damage in areas like the San Pedro Riparian National Conservation Area and Organ Pipe Cactus National Monument, the disruption of Native American sacred sites, and the high financial costs of the project. It concludes by calling for a suspension of construction and a legislative review of the wall's effectiveness and constitutionality.

The clean car standards, initiated by California's AB 1493 and adopted by the California Air Resources Board (CARB), comprise regulations for air quality, global warming, and zero-emission vehicles. These standards aim for a 30% reduction in global warming pollution from new vehicles by 2016 and are more stringent than federal Corporate Average Fuel Economy (CAFE) standards, targeting a fleet average fuel economy equivalent of 39.2 mpg by 2020 compared to the federal 35 mpg. As of January 2009, 13 states and the District of Columbia had adopted these standards, which are projected to reduce cumulative global warming emissions by 451 million metric tons of CO2E by 2020 across those 15 jurisdictions.

The document describes how wind, solar, and biomass energy can provide long-term income and operational savings for U.S. farmers. It highlights specific economic projections from the U.S. Department of Energy, such as the potential for wind energy to create 80,000 jobs and $1.2 billion in income by 2020, and the potential for tripled biomass use to generate $20 billion in new income. The text details the practical applications of these technologies—including turbine leasing, perennial energy crops, and solar-powered farm operations—and notes the availability of federal incentives via the 2002 Farm Bill and various state-level policies like net metering.

The document explains how nuclear power plants use water to absorb waste heat and cool equipment, detailing once-through and closed-cycle cooling systems. It highlights the significant volumes of water required, the environmental impact on aquatic life, and the critical role of the Ultimate Heat Sink (UHS) during accidents. The author argues that the primary safety hazard is not radioactive leakage, but rather the failure of water to reach the plant or leaking into the plant.

The Union of Concerned Scientists analyzed two proposals to increase the Texas Renewable Portfolio Standard (RPS). The more aggressive 20 percent by 2020 proposal would result in 17,820 MW of renewable capacity by 2025, creating 38,290 new jobs and saving consumers $5.6 billion in energy bills. The more modest 10,000 MW by 2025 proposal would yield approximately 8 percent renewable energy by 2025, creating 19,950 new jobs and $5.5 billion in consumer savings. Both proposals would diversify the electricity mix by displacing natural gas and coal, reducing CO2 emissions and providing significant capital investment and tax revenues to rural Texas communities.

The document advocates for 'whole system design' in home construction and renovation, arguing that considering the interconnections between systems, occupants, and the environment can make green homes cost less than conventional ones. It emphasizes a 'passive before active' approach, prioritizing the building envelope and solar orientation to reduce the need for mechanical heating and cooling. Key strategies include optimizing south-facing glazing, utilizing thermal mass (such as masonry or water), and implementing 'cool roof' or 'green roof' systems. The guide also provides a comparative analysis of wall materials—such as straw bale, adobe, and SIPs—based on thermal performance, toxicity, and cost, while introducing Energy Efficient Mortgages (EEMs) as a financing tool for these improvements.

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.
