The document examines the challenges RTOs face as the U.S. grid shifts from large central generators to variable renewables and distributed energy resources (DERs). It argues that 'flexibility'—the ability to respond to changes in supply and demand across various timeframes—is essential for reliability and cost minimization. The authors recommend eliminating self-scheduling for all generators and imports, preserving negative pricing, and improving the coordination between natural gas and electricity markets. It also suggests creating technology-neutral products that value specific capabilities, such as ramping and frequency response, and highlights successful examples like MISO's Dispatchable Intermittent Resource category and CAISO's Flexi-Ramp product.

An analysis of 342 decentralized commitments indicates that the US could meet half of its Paris Agreement climate goals by 2025 if these targets are implemented, with states providing the largest volume of reductions and businesses setting the steepest targets.

The briefing presents a business case for applying R-PACE financing to new residential construction to achieve net-zero energy (NZE) goals. It identifies key market barriers—such as high up-front costs and split incentives between builders and buyers—and proposes a policy framework to integrate R-PACE into new builds. RMI's analysis across six U.S. states suggests that NZE homes can be delivered with no additional up-front cost to the buyer, providing annual energy savings that exceed the PACE assessment payments.

The document synthesizes findings from the Ontario College of Family Physicians (2007, 2012) and the Prince Edward Island Chief Public Health Office (2015) regarding the health risks of pesticides. It identifies significant associations between pesticide exposure and various cancers, reproductive issues, neurological disorders, and respiratory problems, with a particular emphasis on the vulnerability of pregnant women and children. The authors advocate for the precautionary principle and the banning of non-essential cosmetic pesticide use.

The report argues that the cost of the low-carbon energy transition can be minimized by correctly allocating investment risks—such as construction, price, and curtailment—between private investors, public entities, and consumers. It introduces a framework to identify key risks based on technology and country context, select an appropriate ownership model, and use specific instruments (like guarantees or Feed-in Tariffs) to fill risk gaps. Case studies suggest that optimizing risk allocation could reduce levelized costs by 10% for onshore wind in New York and 30-40% for solar in India.

The document argues that federal fuel economy and emissions standards set by the EPA and NHTSA provide significant benefits to New York, including $1.8 billion in savings to date and projected household gains of $1,950 by 2030. It highlights that these standards reduce global warming emissions by an amount equivalent to the electricity needs of New York City and support job creation within the auto industry.

The Union of Concerned Scientists (UCS) identifies New York communities at risk of 'chronic inundation'—defined as high tide flooding 10% or more of usable, non-wetland area at least 26 times per year. Under a high sea level rise scenario, 14 New York communities will face this by 2100, including four New York City boroughs, with significant impacts on Manhattan (12%), Queens (15%), and Brooklyn (15%). Some areas, such as Coney Island and Long Beach, could face chronic inundation as early as 2060. The document argues that curtailing warming to approximately 1.8°C could spare between three and 13 communities by 2100. To address these risks, UCS recommends phasing out risky coastal development, enhancing disaster response frameworks like FEMA's grants, and creating new policies for managed retreat and relocation.

The document asserts that the Paris Agreement is a universal and flexible framework essential for stabilizing global temperature increases below 2°C. It characterizes the U.S. decision to withdraw as an "historical mistake" that could increase future global temperature rises by up to 0.3°C and isolate the U.S. internationally. However, the authors note that a "domino effect" of other nations withdrawing has not occurred, as key players like China, the European Union, and India remain committed. The text highlights that the transition to clean energy is driven by economic opportunity, noting support from major U.S. companies, the divestment from coal by Blackrock, and the competitiveness of renewables, exemplified by subsidy-free auctions in Spain. Internal U.S. opposition is also noted, specifically from the governors of California, New York, and Washington.

The authors assert that the Paris Agreement's universal and flexible design allows it to persist despite the United States' withdrawal. While the US exit is described as a historical mistake that could increase global temperatures by up to 0.3°C, the authors note that key players like China, the EU, and India remain committed. They highlight that the transition to clean energy is driven by economic opportunities, with major US companies and financial institutions like Blackrock divesting from fossil fuels and supporting the agreement for the sake of stability. Additionally, internal US opposition from governors in California, New York, and Washington suggests a continued domestic effort to reduce emissions.

The authors describe the US withdrawal from the Paris Agreement as a historical, economic, and geopolitical error that could slow global progress but may also act as a catalyst for other nations and US subnational entities to maintain climate commitments.

The document asserts that the Paris Agreement's universal and flexible nature allows it to proceed without the United States. It characterizes the U.S. withdrawal as a historical, economic, and geopolitical error that ignores climate science and risks isolating the country. However, it notes that key actors like China, India, and the European Union remain committed, and that internal U.S. resistance from states like California, New York, and Washington, as well as support from major corporations, provides a counterweight to the federal decision.

RMI asserts that while the U.S. federal withdrawal from the Paris Agreement undermines global efforts, the transition to clean energy will continue through the actions of American states, cities, and businesses. The organization highlights the growth of the solar industry and the ability of subnational entities to form an alternative 'societally determined contribution' to maintain climate leadership.

The report examines the potential for electric vehicles to act as flexible loads to balance electricity supply and demand, particularly to mitigate the 'duck curve' caused by high solar penetration. It analyzes technical barriers, utility roles, and rate designs, concluding that managed charging can reduce system costs and emissions if aligned with clean energy availability.

Amory B. Lovins of RMI argues that subsidies for distressed nuclear plants are unjustified because closing high-cost nuclear units and reinvesting their operating expenses into energy efficiency can reduce more carbon than maintaining the plants. He contends that 'baseload' power is not a grid requirement and that variable renewables are more resilient and cost-effective than central thermal plants.

The Union of Concerned Scientists (UCS) developed the Clean Energy Momentum State Ranking to evaluate how US states are driving the transition to clean energy. The ranking uses 12 metrics across three categories: technical progress (renewable energy generation, energy savings, and electric vehicle sales), direct effects (job creation and pollution reduction), and future-oriented policies (renewable energy, energy efficiency, and carbon reduction). California is identified as the overall leader, while Vermont, Massachusetts, Rhode Island, and Hawaii also rank in the top five. The analysis concludes that state-level leadership is critical for national momentum, particularly in creating jobs and improving public health, and recommends that states facilitate business involvement and improve energy equity for low-income communities.

The Union of Concerned Scientists (UCS) created the Clean Energy Momentum State Ranking to evaluate how US states are advancing renewable energy, energy efficiency, and vehicle electrification. California, Vermont, and Massachusetts are identified as top overall leaders. The report emphasizes that state-level policy is a critical driver of progress, particularly in the absence of consistent federal leadership, and that clean energy momentum creates jobs and improves public health by reducing power plant emissions.

The Union of Concerned Scientists ranked U.S. states on their clean energy momentum using 12 metrics divided into technical progress, direct effects, and policy environments. California ranked first overall, followed by Vermont and Massachusetts. The analysis found that 13 percent of U.S. electricity was generated from renewable energy in 2015, and 36 percent of generating capacity being built between 2016 and 2019 is expected to be renewable. Significant reductions in power plant emissions were noted between 2011 and 2015, with sulfur dioxide, nitrogen oxides, and carbon dioxide declining by 47, 24, and 11 percent, respectively.

The Union of Concerned Scientists (UCS) evaluated the 50 US states using 12 indicators to rank their progress in clean energy, focusing on renewable energy generation, energy efficiency, and transport electrification. California leads the ranking, followed by Vermont and Massachusetts. The analysis highlights that clean energy progress is tangible across the US, with wind farms in 41 states and over half a million electric vehicles on the road. The report argues that state-level leadership is critical for job creation and public health improvements, and recommends that states adopt multi-dimensional policies, facilitate corporate participation, and improve energy equity for low-income and minority communities.

RMI defends its research on grid defection, asserting that while full disconnection from the utility may currently only be economical in Hawaii, the declining costs of distributed energy resources (DERs) create a risk of stranded utility assets. RMI critiques a Rochester Institute of Technology (RIT) study for focusing only on present-day costs and a limited set of DER options, arguing that the threat of future defection empowers customers and necessitates reforms in utility business models and retail pricing to achieve an integrated, cost-optimal grid.

The report addresses the conflict between the Northeastern U.S.'s aggressive renewable energy targets and its limited available land. It argues that meeting these goals requires a combination of innovative siting on low-conflict lands (such as brownfields and prison lands), the acceleration of offshore wind, the use of distributed energy resources, and the import of Canadian hydroelectricity. The authors emphasize that overcoming local opposition through early community engagement and 'Smart from the Start' principles is critical to avoiding project delays and failures.
