A coalition of organizations urges Governor Matt Mead of Wyoming to prioritize energy efficiency as the lowest-cost method for reducing emissions and meeting Clean Power Plan goals. The letter argues that expanding utility and non-utility efficiency programs—such as building energy codes and combined heat and power—would save Wyoming residents $2 billion and avoid over 2.6 million tons of carbon dioxide while supporting local job growth.

The report finds that global geothermal operating capacity reached 13.3 GW across 24 countries by January 2016, with a forecast to reach 18.4 GW by 2021. While international growth is supported by COP21 commitments and the Global Geothermal Alliance's goal of 65 GW by 2030, the U.S. market has nearly stalled at 3.7 GW of nameplate capacity due to cheap natural gas and unbalanced tax incentives. The report highlights that only 6-7% of global geothermal potential has been tapped and emphasizes the need for increased public financing to drive private investment in developing nations.

The Union of Concerned Scientists proposes a "Clean Path Case" for Michigan to meet its Clean Power Plan (CPP) target of reducing CO2 emissions by 31 percent below 2012 levels by 2030. This pathway combines the CPP with strengthened renewable energy standards (RES) and energy efficiency resource standards (EERS). The analysis finds that this approach would result in 8,300 MW of new wind and solar capacity, $11.3 billion in clean energy investments, and $4.1 billion in public health and economic benefits by 2030. The report argues that this transition is cost-effective, with only a modest increase in average monthly household electricity bills (less than $3) compared to a scenario with no new policies.

The Union of Concerned Scientists proposes a "Clean Path Case" for New Mexico to meet its Clean Power Plan (CPP) target of reducing carbon dioxide emissions by 24 percent below 2012 levels by 2030. This pathway involves strengthening the state's renewable portfolio standard (RPS) and energy efficiency resource standard (EERS), alongside a mass-based carbon emissions trading program. The analysis indicates that this approach would diversify the electricity mix, reduce household electricity costs, and generate significant health and economic benefits.

The Union of Concerned Scientists analysis suggests that the Clean Power Plan (CPP) can reduce nationwide power plant carbon pollution by approximately 32 percent below 2005 levels by 2030. The proposed 'CPP National Trading Case' emphasizes a combination of wind, solar, and energy efficiency, supported by a national carbon emissions trading program. This approach is projected to generate $103 billion in public health and climate benefits through 2030 and create an average annual revenue of $17.8 billion from carbon allowance auctions between 2022 and 2030. While it may cause a modest near-term increase in household electricity bills, the analysis predicts net savings for consumers by 2030 due to lower operating costs of renewables and efficiency gains.

New Mexico's Clean Power Plan target is a reduction of 4.1 million tons of CO2, or 24 percent below 2012 levels, by 2030. A proposed "Clean Path Case" involving renewable energy and energy efficiency policies, combined with carbon emissions trading, is projected to yield 2,400 MW of new wind and solar capacity and $2.7 billion in capital investments by 2030. This transition could reduce typical household electricity costs by 4.3 percent (approximately $33 annually) and generate $115 million in average annual revenue from carbon allowance sales between 2022 and 2030. Additionally, the reduction of CO2, sulfur dioxide (SO2), and nitrogen oxides (NOx) is estimated to provide cumulative health and economic benefits worth $223 million through 2030. To achieve this, the document recommends that the New Mexico Environment Department develop a mass-based compliance plan, the legislature authorize carbon allowance auctions and expand the Renewable Portfolio Standard (RPS) and Energy Efficiency Resource Standards (EERS), and electricity providers prioritize low-cost renewables.

The Supreme Court suspended the Clean Power Plan, which sets CO2 limits on coal-fired power plants, following a lawsuit by a coalition of states and corporations. Despite this legal action, 61% of adults across the 27 suing states support the policy, with majorities in 23 of those states favoring strict carbon dioxide emission limits to combat global warming and improve public health.

The World Resources Institute asserts that the U.S. Supreme Court's pause on the Clean Power Plan (CPP) is a temporary measure and that the policy remains legally sound and economically beneficial. The CPP is identified as a critical tool for the U.S. to meet its goal of reducing emissions 26-28 percent below 2005 levels by 2025. According to EPA estimates, the plan's health and economic benefits, valued between $25 billion and $65 billion, significantly outweigh the compliance costs of $7 billion to $9 billion. The document notes that many states, including Virginia, Pennsylvania, Michigan, and Missouri, are already positioned to meet or exceed their targets through existing clean energy policies and infrastructure. Furthermore, it highlights a broader trend of climate action among U.S. cities, such as New York and Chicago, and major corporations like Walmart and Microsoft, while urging global adherence to the Paris Agreement.

The document outlines a 'Clean Path Case' for Pennsylvania to reduce CO2 emissions by 29 million tons by 2030. It argues that prioritizing wind, solar, and energy efficiency, combined with a mass-based emissions trading program, would generate billions in capital investments and health benefits while ensuring grid reliability via the PJM Interconnection.

The World Resources Institute (WRI) responds to the U.S. Supreme Court's decision to temporarily halt the Clean Power Plan. WRI asserts that the plan is on solid legal ground and is essential for reducing power sector carbon dioxide emissions by an average of 32 percent from 2005 levels by 2030. The organization emphasizes that the plan supports a low-carbon economy, drives innovation, and improves public health, noting that renewable energy is often now cheaper than traditional fuels.

The FY 2017 budget proposal seeks to increase clean energy R&D funding to $12.8 billion by 2021, featuring a $10.25-per-barrel crude oil tax to fund sustainable transportation and significant increases for the Department of Energy's renewable energy and efficiency programs. It also includes $1.3 billion for the Global Climate Change Initiative and $291 million for Power Africa, while targeting a 83 percent reduction in domestic greenhouse gas emissions by 2050.

The Union of Concerned Scientists argues that Illinois can cost-effectively meet its Clean Power Plan (CPP) target—reducing carbon emissions by 34 percent below 2012 levels by 2030—by adopting a "Clean Path Case." This approach involves strengthening the state's renewable portfolio standard (RPS) and energy efficiency portfolio standard (EEPS) alongside a mass-based emissions trading program. The analysis suggests this pathway would yield nearly 6,000 MW of new wind and solar capacity, reduce typical household electricity costs by 9.4 percent by 2030, and generate $14.3 billion in cumulative health and economic benefits through 2030 by reducing CO2, SO2, and NOx pollution.

The Union of Concerned Scientists proposes a 'Clean Path Case' for Minnesota to meet its Clean Power Plan (CPP) target of reducing power sector emissions by 34 percent below 2012 levels by 2030. This pathway involves strengthening the state's Renewable Electricity Standard (RES) and Energy Efficiency Resource Standard (EERS), alongside a mass-based carbon emissions trading program. The analysis suggests this approach would yield over 4,500 MW of new wind and solar capacity, save the average household $54 annually by 2030, and generate $205 million in average annual revenue from carbon allowance sales between 2022 and 2030. Additionally, the plan is projected to provide $111 million in public health and economic benefits by reducing CO2, SO2, and NOx emissions.

The Union of Concerned Scientists proposes a "Clean Path Case" for Pennsylvania to meet its Clean Power Plan target of reducing emissions by 29 million tons (24% below 2012 levels) by 2030. This pathway combines a mass-based carbon emissions trading program with strengthened renewable energy and energy efficiency policies. The analysis indicates that this approach would yield over 10,700 MW of new wind and solar capacity, generate $804 million in average annual revenue from carbon allowance auctions, and provide $4.5 billion in cumulative health and economic benefits through 2030. Long-term, the plan is projected to reduce typical residential electricity bills by 3.4% by 2030 compared to a reference case with no new policies.

The Union of Concerned Scientists (UCS) utilized the National Renewable Energy Laboratory's (NREL) Regional Energy Deployment System (ReEDS) to assess the Clean Power Plan. The analysis incorporates modified cost and performance assumptions for various energy technologies, including a rejection of EIA 'learning' curves for mature technologies and specific adjustments for nuclear, coal, and renewables. The study compares four scenarios: a Reference Case, a CPP National Trading Case, a CPP No Trading Case, and a 'Clean Path' Case involving enhanced state-level policies in Illinois, Michigan, Minnesota, New Mexico, Pennsylvania, and Virginia.

The Union of Concerned Scientists proposes a "Clean Path" for Virginia to comply with the Clean Power Plan by transitioning from voluntary to mandatory renewable energy and energy efficiency targets and implementing a mass-based carbon emissions-trading program. The analysis suggests this approach would reduce CO2 emissions by 77 million tons through 2030 compared to a reference case, lower typical residential electricity bills by 5% by 2030, and generate an average of $241 million in annual auction revenue for state investments. The report highlights Virginia's current underutilization of its renewable potential, noting that non-hydro renewables accounted for only 2.8% of electricity generation in 2014.

The report analyzes the Eastern Interconnection Planning Collaborative (EIPC) study to demonstrate that aggressive carbon reductions in the U.S. electric sector are achievable with minimal additional cost. By re-evaluating EIPC data, Synapse Energy Economics found that a 'Carbon Reduction' scenario—featuring massive wind build-out and coal retirements—costs approximately the same as a 'Business as Usual' scenario when carbon revenues are recycled. The analysis shows that this path would allow the MISO and PJM regions to significantly over-comply with the Clean Power Plan's emissions targets while maintaining grid reliability.

The Union of Concerned Scientists views the D.C. Circuit Court's decision to keep the Clean Power Plan in effect as a victory for climate action, noting that many U.S. states are already making significant progress toward the plan's 2022 and 2030 carbon emission benchmarks.

The Union of Concerned Scientists (UCS) submitted a public statement to the EPA supporting the Clean Power Plan (CPP) while advocating for a mass-based emissions trading approach for states subject to a federal implementation plan. UCS argues that a mass-based system provides greater certainty for achieving emissions budgets and better integration with future carbon markets. The document provides detailed recommendations for both rate-based and mass-based models, including the expansion of eligible zero-emission resources to include distributed generation and energy efficiency. It also proposes modifications to the Clean Energy Incentive Program (CEIP) to broaden project eligibility timelines and ensure benefits reach low-income communities. Additionally, UCS emphasizes the need to protect voluntary renewable energy markets and suggests implementing interim compliance provisions to prevent emissions deficits.

The document outlines a strategy for Virginia to exceed its Clean Power Plan goals through a revenue-raising carbon trading program and mandatory energy standards. It highlights the state's significant renewable energy potential and projects substantial economic and health benefits, including billions in capital investments and pollution avoidance by 2030.
