Minnesota's electric cooperatives, serving 30% of the state's customers, remain tied to coal-fired power plants in North Dakota, Wisconsin, and Wyoming through Generation & Transmission (G&T) co-ops. While investor-owned utilities in Minnesota are phasing out coal, these co-ops face 'all-requirements' contracts and long-term fuel agreements that restrict their ability to adopt renewables. Many of these out-of-state plants operate uneconomically, costing customers over $93 million between 2015 and 2017.

The report argues that unconventional oil and gas (UOG) development, specifically hydraulic fracturing, poses significant risks to human health, water and air quality, and climate stability. It highlights strong evidence linking UOG to adverse birth outcomes and asthma, while noting that methane leakage undermines the role of natural gas as a 'bridge fuel'. The document calls for a rapid transition to renewable energy and recommends that Canadian provinces and territories implement moratoria on new fracking development.

The report examines the risks associated with unconventional oil and gas extraction (PGNC), specifically hydraulic fracturing. It details significant health concerns, including adverse birth outcomes, asthma exacerbation, and potential links to childhood leukemia. Environmental risks identified include water contamination, air pollution (specifically benzene and ozone precursors), and induced seismicity. The document highlights the disproportionate impact on Indigenous populations and argues that methane leaks undermine the role of natural gas as a transition fuel, calling for a moratorium on new projects and a strategic phase-out to meet Paris Agreement goals.

A February 2020 survey of 1,934 registered voters across 26 U.S. primary states reveals strong support for government action on climate change and a preference for renewable energy over fossil fuels. A majority of respondents support the Green New Deal and specific policies such as a 100% national renewable portfolio standard by 2050. Climate change is a top-tier voting issue for Democrats in these states, and voters indicate they are more likely to support candidates who favor stronger pollution and fuel efficiency standards.

The document analyzes the success of Public Service Company of Colorado (PSCo) in achieving low-cost renewable energy bids through a regulated competitive procurement process. It argues that utilities, as single buyers (monopsonies), have incentives to disadvantage suppliers to maintain market control and financial advantages. To mitigate this, the author proposes specific regulatory measures—such as public planning scrutiny, independent bid evaluators, and the filing of draft requests for proposals—that were implemented by the Colorado Public Utilities Commission (COPUC). The brief concludes that utility ownership and competitive bidding can coexist if the process is transparent and linked to approved resource plans, ensuring consumers benefit from current market prices for wind and solar.

The Clean Air Task Force (CATF) estimates that two EPA rollback proposals from 2018 and 2019 would increase 2025 emissions by 4.3 million metric tons of methane, 1 million metric tons of VOCs, and 38,000 metric tons of HAPs. The 2018 proposal focuses on reducing the frequency of leak detection and repair (LDAR) surveys, while the 2019 proposal seeks to remove regulations for the natural gas transmission and storage segment and eliminate methane standards for the entire sector, which would remove the EPA's obligation to regulate existing facilities. CATF's estimates are significantly higher than the EPA's because CATF accounts for emissions from existing sources and abnormal process conditions, both of which the EPA excludes. The near-term climate impact of the additional methane is compared to the carbon dioxide emissions of approximately 100 coal-fired power plants.

The report argues that a negative feedback loop exists in the United States where restrictive voting laws and partisan gerrymandering insulate legislators from accountability, leading to the adoption of policies that exacerbate public health disparities. Using data from America's Health Rankings and the Cost of Voting Index, the author finds that states with greater partisan bias and higher barriers to voting are associated with lower life expectancy and more severe health declines between 2010 and 2017. Specifically, the report links extreme gerrymandering to higher increases in opioid deaths among African Americans in high-poverty states and higher infant mortality for non-Hispanic black communities. To break this cycle, the document recommends reforms to reduce the costs of eligibility (such as automatic voter registration), reduce the costs of casting a vote (such as early in-person voting), and protect the equal value of votes through independent redistricting commissions and public campaign financing.

The report examines the impact of electronic monitoring services provided by Attenti, a company acquired by Apax Partners in 2017. It argues that these technologies prolong the effects of incarceration by creating 'digital prisons' that hinder employment and social reintegration. The document highlights significant technical failures leading to civil liberty violations, the financial burden placed on low-income users through 'user-funded' schemes, and the lack of scientific evidence supporting the effectiveness of electronic monitoring in reducing recidivism. It also details Attenti's lobbying efforts in several US states to promote the adoption of its services despite these risks.

The report argues that HIG Capital's consolidation of the correctional food and commissary markets through TKC Holdings (comprising Trinity Services Group and Keefe Group) incentivizes the provision of low-quality cafeteria food to drive incarcerated individuals toward expensive commissary purchases. It documents instances of food contamination, riots, and contract terminations in states like Michigan, as well as allegations of bribery and extensive political lobbying. The document also highlights the public health risks of poor nutrition and foodborne illness in correctional facilities, suggesting that improving diets could reduce taxpayer healthcare costs.

The briefing advocates for net-zero energy districts, highlighting how urban-scale planning enables energy balancing across diverse building types, economies of scale for thermal systems, and reduced transportation emissions. It provides examples of smart developments in the US and India that integrate solar microgrids and battery storage to provide grid services and avoid infrastructure costs.

The policy brief contends that new natural gas capacity is a primary driver of increased grid emissions in the US and that avoiding 90% of proposed gas plants could save electricity customers over $29 billion. It advocates for a transition to 'clean energy portfolios'—combinations of wind, solar, batteries, demand flexibility, and energy efficiency—to support economy-wide decarbonization and meet international climate targets.

Following 2019 legislation to decarbonize Colorado's electricity sector, the Public Utilities Commission (PUC) must investigate whether transitioning to performance-based regulation (PBR) is 'net beneficial'. The briefing suggests that the PUC should utilize scenario analysis and collaborative stakeholder processes, drawing on examples from Hawaii, Minnesota, and Oregon to align utility incentives with goals such as emissions reductions and cost-efficiency.

The report explores how large utility customers, including cities and corporations, can achieve high renewable energy goals through various procurement models. It details options such as green tariffs, sleeved PPAs, and community solar, while addressing the critical role of Renewable Energy Certificates (RECs) in accounting and disclosure. The document emphasizes the need for collaboration between utilities, customers, and regulators to ensure that the transition to carbon-free energy is cost-effective, avoids cross-subsidization of non-participants, and maintains grid reliability.

The document details a transition in U.S. energy policy from renewable portfolio standards to Clean Electricity Standards (CES), which allow for a diverse range of zero-carbon technologies, including nuclear and carbon capture. It provides a comprehensive list of states and utility companies that have enacted or pledged 80-100% carbon-free electricity targets, noting that these commitments collectively cover approximately 38% of U.S. electricity sales and 31% of national utility CO2 emissions.

The report details how Securus Technologies, under the ownership of Platinum Equity, extracts high fees from incarcerated individuals and their families for phone calls, money transfers, and e-messaging. It highlights the disproportionate impact on women of color and low-income communities, noting that one in three families go into debt to cover these costs. The document also outlines regulatory risks, including FCC fines and legislative efforts to make prison calls free, as well as severe privacy breaches involving the recording of attorney-client privileged calls and the use of biometric voice prints.

The document highlights that EVs in Colorado produce significantly lower emissions than gasoline cars, with an average of 2.71 metric tons of CO2e per year compared to 4.9 metric tons. It notes substantial fuel savings for drivers, particularly in rural areas where savings can reach $602, and cites a 71 percent increase in Colorado EV sales between 2017 and 2018. The text advocates for the extension of federal tax credits and the expansion of Zero Emission Vehicle (ZEV) programs to lower upfront costs and increase vehicle variety.

The report finds that a significant portion of the U.S. coal fleet is now more expensive to operate than replacing it with new local wind and solar power. In 2018, 74% of the fleet was 'at risk' of being undercut by renewables, a figure projected to rise to 86% by 2025. The analysis emphasizes that these findings are conservative because they only consider resources within 35 miles of existing plants and do not account for broader transmission expansion or combined energy portfolios.

The document provides an overview of energy storage solutions, highlighting the transition from traditional pumped-storage hydropower to advanced battery technologies like lithium-ion. It details the technical trade-offs between different storage methods, the economic trends driving adoption, and the regulatory environment in the U.S. aimed at increasing grid flexibility and resilience.

Climate Central's analysis of U.S. weather data from 1970 to 2018 reveals a broad warming trend, with 91% of assessed stations seeing winter temperatures rise by at least 1°F. This warming threatens the winter sports economy, which supported over 191,000 jobs and contributed $11.3 billion to the national economy in the 2015-16 season. The report highlights a decline in below-freezing days and divergent snowfall trends, with significant decreases in the Western U.S. and increases in the Great Lakes region. Future projections suggest that unchecked emissions could rob states like Colorado of more than a month of below-freezing days by midcentury.

The document explores the integration of customer clean energy demand into utility planning, focusing on the role of Integrated Resource Plans (IRPs) in the US. It argues that early collaboration between utilities and customers can lead to more efficient clean energy procurement, faster decarbonization, and lower costs. The report details the IRP process, identifies barriers to customer engagement—such as limited resources and lack of transparency—and provides pathways for involvement through direct engagement, stakeholder forums, and regulatory proceedings.
