The document evaluates the EIPC's Carbon Reduction Scenario, which aims to reduce carbon emissions in the Eastern Interconnection by 42% below 2005 levels by 2030. Analysis by Synapse Energy Economics indicates that this scenario achieves these reductions with cumulative ratepayer costs through 2040 nearly identical to a 'Business-as-Usual' approach. The scenario relies on a combination of wind energy, energy efficiency, and expanded interregional transmission, specifically projecting 103 GW of new wind in MISO states to support the broader region. The report argues that regional cooperation and updated, lower costs for wind and solar make these targets highly achievable and potentially 30% cheaper than business-as-usual when carbon costs are valued uniformly.

The Union of Concerned Scientists developed the Climate 2030 Blueprint using a modified version of the National Energy Modeling System (UCS-NEMS) to evaluate a 'Blueprint case' against a 'Reference case'. The Blueprint case centers on a cap-and-trade program starting in 2011, designed to reduce U.S. emissions to 26 percent below 2005 levels by 2020 and 56 percent below 2005 levels by 2030. This cap is supported by complementary policies in energy efficiency, electricity generation, and transportation to lower the overall cost of compliance. The analysis incorporates supplemental data on building and industrial efficiency from the American Council for an Energy-Efficient Economy and biomass supply curves from the University of Tennessee and Oak Ridge National Laboratory.

The report identifies energy efficiency as the most cost-effective strategy for cutting U.S. carbon emissions, focusing on the industrial and building sectors which together account for two-thirds of U.S. carbon emissions. It details technical opportunities such as combined-heat-and-power (CHP) systems, building envelope improvements, and high-efficiency appliances. The document proposes a 'Blueprint' of policies—including efficiency standards, resource standards (EERS), and updated building codes—that could reduce total U.S. energy consumption by 29 percent by 2030. It highlights that while technical potential is high, barriers such as 'split incentives' and high up-front costs persist, requiring coordinated federal and state intervention.

The report argues that the United States can significantly reduce its reliance on fossil fuels by deploying a diverse mix of renewable energy sources, which have the technical potential to meet current electricity needs many times over. It highlights wind, solar, geothermal, bioenergy, and hydropower as key resources, noting that wind and geothermal are already competitive with new coal and natural gas plants in some cases. The document identifies critical barriers to this transition, including the need for a modernized transmission grid, streamlined siting processes, and sustainable biomass harvesting. It proposes a policy package featuring a national renewable electricity standard (RES) ramping up to 40% by 2030, extended tax credits, and increased R&D funding. While discussing carbon capture and storage (CCS) and advanced nuclear power as potential low-carbon supplements, the report notes significant cost uncertainties, infrastructure requirements, and safety risks associated with these technologies.

The Climate 2030 Blueprint proposes a combination of a cap-and-trade program and sector-specific complementary policies to reduce U.S. heat-trapping emissions. The analysis indicates that by 2030, the Blueprint could achieve a 56 percent drop in emissions from 2005 levels while generating net annual savings of $464 billion for consumers and businesses. The electricity sector is identified as the primary driver of these reductions, with significant contributions from energy efficiency and renewable energy. The report also highlights improvements in energy security through reduced oil imports and the potential for carbon sequestration in U.S. forests and farmlands.

The document outlines modifications to the EIA's AEO 2008 NEMS model to better reflect actual construction costs, updated tax credits, and state renewable electricity standards. It provides detailed capital cost and performance assumptions for various energy technologies, including wind, solar, geothermal, coal, natural gas, and nuclear power. The authors argue that EIA costs often underestimate actual project expenses, particularly for nuclear and coal plants. The text also defines a 'Blueprint Case' featuring a national renewable electricity standard ramping up to 40% by 2030 and a federal demonstration program for coal with carbon capture and storage. Finally, it assesses the technical potential of various renewable resources across the U.S.

The document outlines conservative estimates for biomass energy supply in the US, focusing on energy crops, agricultural residues, forestry residues, and urban/mill residues. It details the use of the POLYSYS model to assess land-use changes, specifically for switchgrass, and provides the methodology for calculating land-use impacts for other renewable energy technologies and avoided coal mining.

The U.S. electricity system relies heavily on freshwater, with cooling power plants accounting for 41 percent of all freshwater withdrawals. This dependence creates a 'collision' where energy production competes with municipal, agricultural, and ecosystem needs, a situation exacerbated by global warming. The report details regional risks—such as hydropower instability in the Northwest and cooling water shortages in the Southeast—and highlights low-water alternatives like wind, solar photovoltaic, and dry-cooling systems.

The document details five modeling scenarios for US decarbonization, comparing a business-as-usual reference case against pathways aiming for net zero emissions by 2050. It provides quantitative data on emissions, energy supply, and technology deployment, specifically highlighting the roles of electrification, renewable energy, and carbon capture.

The Union of Concerned Scientists finds that increasing Wisconsin's renewable electricity standard to 25% by 2025 is achievable and affordable. Under the most likely 'No Hydro Imports' scenario, the state would see a $59 million reduction in electricity bills (when accounting for carbon savings), the creation of 2,650 new jobs, and a reduction in CO2 emissions equivalent to removing 2.1 million cars from the road. The analysis highlights Wisconsin's significant technical potential in wind, solar, and biomass to meet these targets while reducing reliance on imported fossil fuels.
