The document describes how climate change and human pressures will affect the Great Lakes Region, specifically highlighting risks to human health, the regional economy, and the cultural sense of place.

The report examines the risks associated with unconventional oil and gas development, specifically hydraulic fracturing, in the United States. It identifies significant threats to groundwater and surface water quality, air pollution, and induced seismic activity from wastewater injection. The authors highlight how corporate and political interference—including 'trade secret' exemptions and non-disclosure agreements—hampers scientific research and public knowledge. It critiques the 'patchwork' of state laws and federal loopholes, such as the 'Halliburton loophole,' and recommends mandatory baseline monitoring, full chemical disclosure, and the closing of federal regulatory gaps to protect public health and the environment.

The report argues that the current U.S. agricultural landscape is dominated by corn and soybeans due to federal subsidies, which contradicts national nutritional goals. Using economic modeling, the authors find that aligning production with healthy dietary guidelines would significantly increase fruit and vegetable acreage while reducing cereal grain production. Such a transition would likely improve public health, reduce environmental degradation from monocropping and livestock operations, and create new economic opportunities for farmers, particularly in the Midwest.

The report details a September 2013 briefing on America’s Power Plan (APP), focusing on the transition to a high-renewables future in the U.S. Midwest. It examines the need for new utility business models to handle decarbonization and distributed energy resources (DERs), highlights Minnesota's legislative progress on solar and renewable standards, and discusses Xcel Energy's experience integrating variable wind power. Key recommendations include adopting performance-based regulation, streamlining 'soft costs' for solar PV, and integrating distribution planning into state resource processes.

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.

The report examines the environmental, logistic, and infrastructural barriers to commercializing cellulosic ethanol from corn stover in the US, concluding that the country will likely fall short of RFS2 mandates.

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 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 analyzes the potential for the Midwest to transition to a clean energy economy by adopting the Midwestern Governors Association's (MGA) targets: reducing electricity use by 2% annually and sourcing 30% of electricity from renewables by 2030. Using a modified National Energy Modeling System (NEMS), the Union of Concerned Scientists finds that these goals are achievable and would lead to significant job creation, consumer savings, and carbon emission reductions. The analysis highlights wind and biopower as the most competitive resources, while noting that transmission capacity remains a primary barrier. The report argues that regional targets would complement a federal carbon policy, making such a policy more affordable for consumers.

The report documents the presence of hexavalent chromium, a known carcinogen, in leachate from coal ash disposal sites and groundwater across the United States. It highlights a discrepancy between the EPA's recognition of the chemical's toxicity in drinking water and its failure to account for ingestion risks in its coal ash risk assessments. The document provides evidence from EPA, DOE, and EPRI studies showing that chromium leaching from coal ash is nearly 100% hexavalent and often exceeds safety standards by thousands of times. It concludes that the EPA must designate coal ash as a hazardous waste under the Resource Conservation and Recovery Act to protect public health.

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).

In 2008, Wisconsin spent $853 million to import all the coal used by its power plants from nine other states. The state is the 5th most dependent on net imports as a share of total power use (68%). We Energies is the largest importer, spending $313 million, with its Pleasant Prairie facility being the most import-dependent site. To reduce this dependence, the document suggests expanding energy efficiency resource standards and leveraging renewable energy, noting that Wisconsin has the technical potential to generate 4.2 times its 2008 electricity needs from renewables, primarily wind and bioenergy.

The report analyzes how carbon pricing may affect the US Midwest, a region characterized by high carbon intensity due to coal dependency and a large manufacturing base. While carbon pricing could increase short-term costs for energy-intensive industries, the report argues it presents a long-term opportunity for the region to lead in low-carbon production and 'green collar' jobs. It highlights the Midwest's significant mitigation potential and the role of the Midwestern Greenhouse Gas Accord in driving this transition.

The report projects that Wisconsin will face significantly hotter summers, increased flooding, and agricultural disruptions if current emissions trends continue. Under a high-emissions scenario, Milwaukee could see more than 55 days per summer over 90°F by the end of the century. The document advocates for a transition to clean energy through renewable electricity standards, energy efficiency, and federal cap-and-trade policies to mitigate these risks.

As of February 2009, 28 U.S. states and Washington D.C. have implemented renewable electricity standards to increase the share of wind, solar, and bioenergy in their power supplies. The Union of Concerned Scientists projects these standards will support 76,750 MW of new renewable power by 2025, reducing annual carbon dioxide emissions by over 183 million metric tons. While success varies by state—with Texas significantly exceeding its targets—the document argues that state leadership proves these standards can reduce market barriers, justifying a national renewable electricity standard to enhance energy security and fuel diversity.

The document details the aftermath of the 2008 Kingston disaster, where over 1 billion gallons of coal ash slurry were released. It tracks TVA's legal battles, the health impacts on local communities and cleanup workers, the disposal of ash in Perry County, Alabama, and the prolonged struggle to compel the EPA to finalize federal coal ash disposal regulations by 2014.

The briefing examines the European Union's Emission Trading Scheme (EU ETS), the Regional Greenhouse Gas Initiative (RGGI), the Western Climate Initiative (WCI), and the Midwestern Regional Greenhouse Gas Reduction Accord. It argues that for cap-and-trade to be effective, the emissions cap must be sufficiently tight and the distribution of allowances should favor auctioning over free allocation to avoid windfall profits for firms.

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 the potential effects of Washington's Initiative 937 (I-937), which would require large electric utilities to source 15 percent of electricity from eligible renewable resources by 2020 and pursue cost-effective energy conservation. Under an expected case scenario, the report projects that by 2025, I-937 would result in $1.13 billion in cumulative savings on consumer electricity bills, the creation of 2,000 new jobs, and a reduction of 4.6 million metric tons of annual CO2 emissions. The analysis indicates that renewable energy and efficiency investments would be cost-competitive with conventional fossil fuel resources, providing long-term price stability and economic development, including $2.9 billion in new capital investment. Sensitivity analyses suggest that even under pessimistic conditions—such as higher wind costs or the expiration of federal tax credits—the initiative would generally still yield long-term savings and environmental benefits.

The report assesses how rising temperatures and shifting precipitation patterns will affect the Great Lakes region, predicting warmer, drier summers and increased extreme weather. It details vulnerabilities in aquatic and terrestrial ecosystems, agriculture, and human health, while recommending emission reductions and adaptive management.
