The Union of Concerned Scientists finds that significant portions of the U.S. East and Gulf Coast electricity grids are currently exposed to coastal flooding, a risk that will increase as sea levels rise. In the central Gulf Coast specifically, 188 major substations and 20 power plants are currently at risk from a major storm. The report argues that relying on historical flood data is insufficient and recommends a combination of infrastructure adaptation (protection, accommodation, and retreat) and the deployment of decentralized clean energy solutions—such as microgrids and solar with storage—to ensure community resilience and reduce the carbon emissions driving sea level rise.

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 document defines on-bill financing (OBF) as a mechanism where energy improvement costs are repaid via monthly utility bills. It argues that OBF reduces high up-front costs and expands access to financing by using utility payment history instead of traditional credit scores. The guide provides four case studies from Kansas, South Carolina, Florida, and Oregon, demonstrating that OBF can support a range of upgrades from weatherization to solar PV with very low default rates (typically under 3%).

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 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 'Help My House' pilot project provided energy-efficient upgrades—including heat pumps, insulation, and air leak sealing—to electrical cooperative members in South Carolina at no upfront cost. Participants experienced significant reductions in monthly electric bills and improved home comfort. On average, participating houses reduced electricity use by 34 percent, resulting in an average annual saving of $288 after loan payments, with projected savings exceeding $1,100 annually once loans are repaid.

The Help My House (HMH) pilot program provided on-bill financing (OBF) for energy efficiency retrofits in 125 homes across eight South Carolina electric cooperatives. The program demonstrated that 'whole house' upgrades—primarily attic insulation, air sealing, and HVAC replacements—could reduce electricity use by an average of 34% (approximately 11,000 kWh per year), with energy savings typically exceeding the annual loan repayments. The pilot achieved a 93% realization rate compared to predicted savings and significantly increased member satisfaction, leading several participating cooperatives to launch their own ongoing OBF programs. While the retrofits reduced coincident peak demand, they had no net impact on the system load factor, suggesting that the simultaneous deployment of load control devices is necessary to improve system efficiency.

The document explains that global sea level has risen approximately eight inches since the Industrial Revolution, driven primarily by thermal expansion and the melting of land ice due to global warming. It highlights that the U.S. East and Gulf coasts are experiencing some of the world's fastest rates of rise. Projections for 2100 range from 8 inches to 6.6 feet, with significant risks of permanent inundation, amplified storm surges, and shoreline erosion for over 100 million Americans living in coastal counties. The report argues that while adaptation is necessary, reducing heat-trapping emissions is the most effective way to limit the pace and magnitude of future sea level rise.

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.

A group of environmental and scientific organizations argues against the EPA's proposal to include Arundo donax (giant reed) as an approved advanced biofuel feedstock. They cite the species' status as a high-risk invasive weed that threatens native vegetation and endangered species, noting that the high cost of eradication makes the ecological and economic risks outweigh the benefits of its cultivation under the Renewable Fuel Standard.

The document examines requests from livestock producers and state governors to waive the Renewable Fuel Standard (RFS) to lower corn feed prices during a drought. It argues against a waiver, noting that ethanol production has already decreased, tradable credits provide flexibility, and a waiver would only marginally lower corn prices while severely harming the biofuels industry and its investments.

The "Help My House" pilot program in South Carolina used on-bill financing to enable homeowners to fund energy efficiency retrofits, achieving 125% of its goal by February 2012. Supported by a $740,000 USDA Rural Utility Service loan, the program provided 2.5% financing tied to the electric meter, bypassing traditional credit checks. The pilot resulted in an average loan of $7,684 per home, with projected annual energy savings of 11,593 kWh and an average energy reduction of 35% per home.

On-bill financing allows homeowners to implement energy efficiency improvements by receiving low-interest loans from utilities, with repayments added to their monthly utility bills. This model overcomes upfront cost barriers and can achieve 'deep impact' energy savings of 20 percent or more, which traditional rebate programs often fail to encourage. The document distinguishes between tariff-based systems, which tie loans to the meter and can address landlord-tenant split incentives, and on-bill loans, which typically function as non-transferable personal or business loans. A South Carolina pilot program called 'Help My House' demonstrated the effectiveness of this approach, achieving projected average energy savings of 35 percent per home.

The Rural Energy Savings Program (RESP) is a proposed U.S. legislative initiative to provide low-interest loans to public and cooperative electric utilities, which in turn offer on-bill financing to rural homeowners for energy efficiency improvements. The program aims to reduce utility bills and greenhouse gas emissions while creating local jobs. The briefing outlines the program's operational requirements, compares House and Senate versions of the legislation, and highlights existing on-bill financing examples in Kansas, South Carolina, and New York.

The report analyzes 15 significant safety-related 'near-misses' at U.S. nuclear plants in 2011, arguing that many resulted from owners tolerating known safety problems. While it highlights successful NRC interventions at the Fort Calhoun, Hatch, and LaSalle plants, it criticizes the agency for allowing 47 reactors to operate in violation of fire-protection regulations and 27 reactors to operate with deficient seismic protection. The author contends that the NRC often focuses on fixing individual equipment failures rather than addressing the systemic weaknesses in owners' testing and inspection regimes.

The document criticizes 260 U.S. House members who voted on June 21, 2012, to include a provision in a transportation bill that allows coal ash ponds to operate without basic safety standards and prevents the EPA from establishing national health and safety regulations. It highlights that these members represent districts containing the vast majority of the U.S.'s hazardous coal ash sites and notes a correlation between these votes and campaign contributions from the electric utility and mining industries.

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 Union of Concerned Scientists outlines 23 recommendations to improve U.S. nuclear safety, arguing that the Nuclear Regulatory Commission (NRC) prioritizes business interests over public safety. Key proposals include extending regulations to cover 'severe' accidents, expanding emergency planning zones beyond 10 miles, and mandating the transfer of spent fuel from pools to dry casks. The report also calls for more realistic terrorist threat assumptions, stricter fire protection enforcement, and an increase in the dollar value assigned to human life in cost-benefit analyses to justify necessary safety retrofits.
