The document contends that the U.S. EPA has failed to protect minority and low-income Americans from coal ash pollution, the second largest source of industrial waste in the U.S. It argues that the 2014 coal ash rule is insufficient because it places the burden of enforcement on citizens and allows the continued use of dangerous, unlined coal ash lagoons, which are predominantly located in vulnerable neighborhoods. The text calls for immediate EPA action, including drinking water testing and technical assistance for affected communities, to address these civil rights and public health disparities.

The Union of Concerned Scientists (UCS) analysis finds that two-thirds of U.S. states may be exposing electricity consumers to financial risks due to overreliance on natural gas. These risks include price volatility, potential carbon pricing costs, and the possibility of stranded assets such as underused plants and pipelines. The report rates states across five categories, identifying Florida as the only state with a "High" risk rating in all five. To mitigate these risks, the report advocates for prioritizing renewable energy and energy efficiency over natural gas as a primary solution for carbon reduction under the federal Clean Power Plan.

The report argues that demand flexibility—the use of technology to shift electricity use across hours of the day—can significantly lower both customer bills and grid investment costs. In the U.S. residential sector, it could avoid $13 billion annually in grid and energy costs while reducing customer bills by 10–40%. The analysis highlights that 'flexiwatts' from appliances like air conditioning and water heaters can reduce peak demand and better integrate renewable energy. However, the report warns that demand flexibility may accelerate 'load defection' if utilities reduce compensation for exported rooftop solar PV.

The report analyzes 'demand flexibility' (DF)—the use of technology to shift electricity loads like air conditioning and EV charging to lower-cost times. It finds that widespread residential DF could avoid $13 billion annually in U.S. grid costs and reduce customer bills by 10–40%. Through four case studies (ComEd, SRP, HECO, and Alabama Power), the report demonstrates how DF can mitigate peak demand, integrate rooftop solar PV, and provide a lower-cost alternative to traditional grid infrastructure investments.

A coalition of 290 organizations and individuals opposes H.R. 1734, asserting that the bill would weaken the U.S. Environmental Protection Agency's (EPA) 2014 coal ash rule. The signatories argue the legislation would delay health protections, eliminate public access to information, and remove national standards for drinking water protection, thereby increasing risks to vulnerable communities and the environment.

The report evaluates the NRC's 2014 safety oversight, noting a decline in the number and severity of 'near misses' but criticizing the agency for withholding safety documents, retaliating against whistleblowers, and applying inconsistent oversight standards across different regions.

The document outlines various energy storage technologies—including pumped hydro, batteries, thermal, compressed air, flywheels, and hydrogen—detailing how they balance electricity supply and demand. It highlights the transition from a reliance on pumped hydroelectric storage toward rapidly scaling lithium-ion batteries, noting a 72 percent drop in battery capital costs between 2015 and 2019. The guide argues that energy storage enhances grid reliability, enables higher renewable energy integration, and provides community benefits by replacing polluting fossil fuel 'peaker' plants and increasing resilience against extreme weather.

The 2024 data for Alabama indicates that while a majority of residents (62%) believe global warming is occurring, there is a split in perception regarding its cause, with 51% attributing it to human activities. Support for clean energy transitions and renewable energy research is notable, with 57% supporting a transition to 100% clean energy by 2050 and 72% supporting renewable energy research. Risk perceptions are significant, as 54% of residents are worried about global warming and 61% believe it will harm future generations and animal species.

Earthjustice, on behalf of Sierra Club and ForestEthics, petitions the U.S. Department of Transportation (DOT) to ban legacy DOT-111 tank cars for transporting highly flammable crude oil. The petition argues that these cars pose an "unacceptable public risk" due to high failure rates in derailments, citing disasters in Lac Mégantic, Aliceville, and Casselton. While the DOT has initiated rulemaking and issued operational emergency orders, the petitioners contend these actions are insufficient and too slow to address the imminent hazard. They highlight that Canada has already implemented bans and surcharges on these cars, which may inadvertently push the most dangerous tank cars into the U.S. fleet. The document advocates for an immediate emergency order to bridge the gap until a formal rulemaking process establishes more robust safety standards, such as the CPC-1232 specifications or newer designs.

The Union of Concerned Scientists (UCS) evaluates the NRC's 2013 performance, noting a decrease in the number and severity of 'near-misses' but highlighting critical inconsistencies in enforcement. While the NRC successfully managed the restart of the Fort Calhoun plant and identified gaps in aging component oversight, it is criticized for allowing the Diablo Canyon and Oconee plants to operate despite known seismic and fire safety risks, and for improperly withholding information regarding the Jocassee Dam's potential to cause a total meltdown at Oconee.

The 2013 update to the 'Ripe for Retirement' report identifies that up to 329 coal-fired generators (58.7 GW) in 38 U.S. states are no longer economically competitive with existing natural gas plants, and up to 71 GW are uncompetitive with new wind power. These units, combined with those already retired or announced for retirement, represent more than one-third of the country's coal-generating capacity. The analysis suggests that a combination of renewable energy, energy efficiency, and underutilized natural gas plants can replace this capacity, though the authors warn against overdependence on natural gas due to climate and economic risks.

The document asserts that CCS is the only available technology allowing coal and gas power generation at near-zero emissions and is a 'Best System of Emission Reduction' under the Clean Air Act. It highlights the flexibility of the EPA's proposed rules, such as an emission limit of 1100 lbs/MWh and an eight-year compliance window, which allow for partial capture. The testimony provides evidence of CCS deployment in industrial and power sectors, including projects like the Dakota Gasification Plant and the Texas Clean Energy Project. It also addresses the economic viability of CCS, noting that enhanced oil recovery (EOR) can offset costs, and argues that U.S. geologic storage capacity is sufficient to handle power sector emissions for a century or more, countering concerns about induced seismicity.

The document describes a water resource systems model for the Apalachicola–Chattahoochee–Flint, Alabama–Coosa–Tallapoosa, and Tombigbee River basins. The model integrates electricity generation, agricultural, and municipal water use to assess impacts on streamflow and water temperatures, specifically addressing thermal pollution from power plant cooling. Validation against 1980–2010 data shows the model robustly represents monthly average streamflow and water temperatures.

The document examines various energy storage technologies, ranging from established systems like pumped hydro and compressed air energy storage (CAES) to emerging solutions like flow batteries and flywheels. It highlights the critical role of U.S. federal initiatives, specifically Department of Energy (DOE) grants and Federal Energy Regulatory Commission (FERC) orders, in reducing financial risks and reforming market access to encourage utility-scale implementation. The brief also details specific U.S. projects and proposed legislation, such as the STORAGE Act, aimed at incentivizing storage to support grid stability and the integration of variable renewable energy.

The document examines various energy storage technologies, from established methods like pumped hydro to emerging battery and flywheel systems, highlighting their role in integrating renewable energy and stabilizing the grid. It details the impact of FERC Orders 1000 and 755 and DOE initiatives, such as the Joint Center for Energy Storage Research (JCESR), in reducing technical and economic hurdles. Additionally, it profiles several large-scale U.S. projects and discusses proposed legislation, including the STORAGE Act, aimed at incentivizing storage deployment through tax credits.

Abigail Dillen of Earthjustice testifies that the 'Reducing Excessive Deadline Obligations Act of 2013' is a misguided attempt to derail lawsuits seeking to compel the EPA to regulate coal ash. The testimony highlights the severe environmental and health risks associated with the current lack of federal standards, including groundwater contamination by toxic metals, air pollution from fugitive dust, and the catastrophic potential for coal ash impoundment failures. Dillen emphasizes that the EPA has delayed necessary regulations for 13 years despite acknowledging their need, and that the proposed bill would leave the second largest toxic waste stream in the U.S. unregulated indefinitely.

Earthjustice is challenging the Tennessee Department of Environmental Conservation's (TDEC) wastewater discharge permit for the TVA Gallatin coal plant, arguing that the permit fails to limit toxic metal discharges into local waterways and groundwater. The case also seeks to address the plant's cooling system, which kills tens of thousands of fish annually, and highlights a history of TVA coal ash spills at the Kingston and Widows Creek plants.

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.

The Union of Concerned Scientists identifies hundreds of U.S. coal generators as 'ripe for retirement' due to high operating costs and vulnerability to 'energy-water collisions.' Many of these plants rely on once-through cooling systems that withdraw massive amounts of water and are subject to strict EPA temperature discharge limits. The report argues that replacing these aging plants with renewables or energy efficiency would significantly reduce national water withdrawals and consumption, particularly in states like Alabama, Maryland, Michigan, and Wisconsin.

The Union of Concerned Scientists identifies a significant number of U.S. coal-fired power plants that are economically uncompetitive compared to natural gas and wind power. The report argues that retiring these plants, along with those already scheduled for closure, would improve public health and reduce carbon emissions without jeopardizing grid reliability.
