The document provides a comprehensive overview of nuclear power, detailing the process of fission and the operation of pressurized and boiling water reactors. It examines the uranium fuel cycle, noting that the U.S. relies heavily on imports from countries like Russia and Canada. The text also addresses the challenges of radioactive waste storage, specifically mentioning Yucca Mountain, and analyzes the economic decline of the U.S. nuclear industry following the 1970s due to cost overruns, declining energy demand, and public opposition.

South Carolina spent $1.1 billion on net coal imports in 2008, ranking 11th highest in total net imports in the U.S. The state relies on coal for 40.6% of its electricity generation despite having no in-state coal supplies. The Union of Concerned Scientists argues that investing in energy efficiency and homegrown renewables, such as offshore wind and solar, could redirect funds back into the local economy and improve energy independence.

The report documents 31 cases of environmental contamination from coal combustion waste (CCW) across 14 US states, identifying that 15 sites have off-site contamination exceeding drinking water or surface water standards, while 16 show severe on-site pollution. It highlights the presence of toxic metals such as arsenic, lead, and selenium, and argues that the lack of federal regulation for CCW disposal poses a significant risk to public health and the environment, particularly in low-income communities.

The document analyzes the challenges facing the U.S. advanced biofuels industry, including the 'valley of death' between pilot projects and commercialization, volatile petroleum prices, and regulatory uncertainties. It argues that while the federal government provides essential broad-scale support, state governments are uniquely positioned to guide the industry by leveraging local geography and resources. The report proposes ten specific policy options for states, ranging from resource inventorying and sustainable feedstock guidelines to the implementation of low carbon fuel standards and interagency cooperation, highlighting examples from states like California, Oregon, and Tennessee.

The document reports that fossil fuels accounted for 71% of South Carolina's energy consumption as of 2006, driven by demand in transportation, industry, and electricity generation. Between 1990 and 2005, the state's greenhouse gas emissions grew by 42%, a rate more than double the U.S. average, with 90% of those emissions resulting from energy consumption, primarily the combustion of coal and petroleum.

The document identifies that South Carolina has the potential to generate an additional 25,000 GWh of electricity from renewable resources by 2025, which would represent approximately 30 percent of current electricity sales. It advocates for a renewable electricity standard (RES) with a target of 25 percent by 2025, alongside financial incentives and grid infrastructure improvements. The report compares various power resources, noting that while renewable and conventional options have comparable total costs for new generation, renewables offer superior performance regarding water use, air quality, and climate impacts.

The document argues that a national energy efficiency resource standard (EERS) would provide South Carolina with significant electricity savings, job creation, and CO2 emission reductions by 2020, while noting that energy efficiency is the most cost-effective way to meet new energy needs.

The Southeast United States faces significant challenges in balancing water and energy needs due to population growth and frequent droughts. Thermoelectric power plants are the region's largest freshwater consumers, while water heating and treatment are major energy drivers. The document advocates for integrated policy priorities, including the adoption of water-efficient energy technologies, energy-efficient public buildings, and financial incentives for high-performance products like ENERGY STAR and WaterSense labels.

The document highlights the significant water requirements of thermoelectric power plants in South Carolina and the energy costs associated with water heating and treatment, proposing policy priorities to improve efficiency in both sectors.

The Southeast United States accounts for 20% of U.S. energy consumption and greenhouse gas emissions, with a heavy reliance on fossil fuels (80%) and high per capita electricity use. Rapid population growth is projected to increase energy demand, particularly in electricity generation, which already constitutes 45% of regional energy consumption. The region's dependence on imported fossil fuels exposes it to price volatility and supply disruptions, while its emissions profile makes it a significant global contributor to climate change.

The Southeast United States has sufficient renewable energy resources to meet up to 30 percent of its electric power needs by 2025. The region can leverage biomass, solar, wind, and low-impact hydropower to reduce reliance on conventional power, though this requires overcoming regulatory barriers such as restrictive third-party power pricing and insufficient interconnection rules. The document argues that a national or state-level renewable electricity standard (RES) would drive job growth and economic investment with minimal impact on consumer electricity costs.

The document argues that energy efficiency is the most cost-effective way to meet rising electricity demand in the Southeast US, potentially reducing expected use by 20% by 2025. It identifies regulatory and financial barriers and recommends the adoption of Energy Efficiency Resource Standards (EERS), updated building codes, and alternative utility business models to drive investment across residential, commercial, and industrial sectors.

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 2006 School Bus Pollution Report Card by the Union of Concerned Scientists finds that U.S. school buses are among the oldest vehicles on the road, with an average age of nine years, and emit nearly twice as much soot per mile as tractor-trailer trucks. The report grades states on tailpipe soot emissions, smog-forming pollution, and the success of their cleanup programs. While some states like California and Washington have made significant strides in reducing soot through retrofits and cleaner fuels, national soot pollution from school buses has only decreased by more than two percent. The document highlights the vulnerability of children to diesel exhaust, which is linked to asthma and lung growth deficits, and argues that substantial federal and state investment is needed for bus replacement and the installation of particulate traps.

The report evaluates U.S. school bus emissions, finding that older diesel buses release significantly more soot than modern alternatives, posing health risks to children. It grades states on soot emissions, cleanup programs, and smog-forming pollution, noting wide performance gaps. The authors recommend a strategy of 'the five Rs'—retrofitting, refueling, replacement, repair, and reduced idling—and call for strengthened federal standards and increased funding to modernize fleets.

The report asserts that while the 1990 Clean Air Act Amendments reduced sulfur dioxide and nitrogen oxide emissions, ecosystems in North America remain damaged due to a 150-year accumulation of acidic compounds. It documents ongoing damage to aquatic life, forests, and wildlife, and argues that biological recovery requires emission cuts up to 80 percent beyond the 1990 mandates. The authors state that affordable technologies, such as scrubbers and renewable energy, are available to achieve these deeper reductions.

The report details the environmental and health risks associated with the disposal of over 100 million tons of annual coal and oil combustion waste in the United States. It highlights that 76 million tons are typically disposed of in unlined, unmonitored onsite lagoons and landfills, leading to groundwater contamination and ecological damage. The authors argue that current state-level regulations are inconsistent and insufficient, and that the EPA's preliminary determination to maintain a regulatory exemption for these wastes ignores significant risks to low-income communities and people of color. The document calls for federal oversight under RCRA to mandate modern environmental controls like liners and groundwater monitoring.

The Union of Concerned Scientists (UCS) monitored 10 US nuclear power plants and found a "serious breakdown in quality assurance," noting that internal auditors failed to identify any of the 200+ reported incidents. The study found that 44 percent of problems were caused by poor procedures and 35 percent by worker mistakes. While some plants like Surry and Oyster Creek demonstrated proactive safety cultures, others like LaSalle and Sequoyah showed systemic failures, including ignored warnings and repetitive errors. UCS recommends better training for auditors and workers, revised procedures, and stronger NRC enforcement.

The report examines the environmental and health risks associated with dumping coal combustion waste (CCW), or coal ash, into active and abandoned coal mines across the United States. It argues that this practice, often labeled as 'beneficial use' or 'recycling' to bypass regulations, allows toxic metals to leach into groundwater and surface water. The document highlights the failure of the U.S. EPA and the Office of Surface Mining to implement necessary safeguards, noting that minefilling is driven by economic incentives, reducing disposal costs by 89 to 95 percent compared to engineered landfills. It specifically identifies the increased risks from Fluidized Bed Combustion (FBC) plants and provides case studies of contamination in Pennsylvania and New Mexico. The report concludes by urging the EPA to adopt the National Academies of Sciences' recommendations for mandatory testing, site characterization, and long-term monitoring.
