The report analyzes how battery energy storage can provide thirteen different services across three grid levels: transmission, distribution, and behind-the-meter. It argues that while single-use batteries are often underutilized and economically unviable, 'stacking' multiple services—such as combining demand charge reduction with wholesale grid services—can make storage a cash-positive investment. Through four U.S. case studies, the report demonstrates that behind-the-meter systems are technically capable of providing the widest array of services, though significant regulatory barriers currently hinder this potential.

Large-scale solar PV systems have grown rapidly, accounting for over half of all solar capacity installed between 2010 and 2014. These projects benefit from economies of scale, with costs in 2013 averaging half of those in 2010, making them significantly cheaper than residential solar. While they generate electricity without carbon emissions or water consumption, they require substantial land area, which can impact habitats. Mitigation strategies include using degraded lands, such as landfills. Growth is supported by federal tax credits, state renewable electricity standards, and permitting reforms.

The paper examines how different DER ownership models can be used to integrate cost-effective technologies into outdated regulatory frameworks. It argues that no single model is universal, but each can work if the value proposition aligns with the public interest and utilizes an adaptive approach prioritizing fair compensation and transparency. Utility-owned models are effective for early adoption and public goals but risk cost overruns and market power issues. Third-party and customer-owned models excel when they have transparent access to the full value of DERs through dynamic rate design or competitive markets.

The report argues that demand flexibility—the use of technology to shift electricity use across hours of the day—can significantly lower both customer bills and grid investment costs. In the U.S. residential sector, it could avoid $13 billion annually in grid and energy costs while reducing customer bills by 10–40%. The analysis highlights that 'flexiwatts' from appliances like air conditioning and water heaters can reduce peak demand and better integrate renewable energy. However, the report warns that demand flexibility may accelerate 'load defection' if utilities reduce compensation for exported rooftop solar PV.

The report analyzes 'demand flexibility' (DF)—the use of technology to shift electricity loads like air conditioning and EV charging to lower-cost times. It finds that widespread residential DF could avoid $13 billion annually in U.S. grid costs and reduce customer bills by 10–40%. Through four case studies (ComEd, SRP, HECO, and Alabama Power), the report demonstrates how DF can mitigate peak demand, integrate rooftop solar PV, and provide a lower-cost alternative to traditional grid infrastructure investments.

In Q1 2015, 44 green bonds totaling $7.2 billion were issued. The market showed signs of maturation through the use of 11 different currencies and credit ratings ranging from AAA to B-. India emerged as a key player with its first corporate green bonds from Yes Bank, while US municipal bonds grew in the water and green building sectors, though often lacking independent verification. Development banks remained leaders, accounting for approximately 46.2% of issuance. Renewable energy, green buildings, and water were the primary funding targets. Investors showed strong demand, evidenced by oversubscription and the formation of dedicated green bond funds and investor expectation statements to combat 'greenwashing'.

A coalition of 290 organizations and individuals opposes H.R. 1734, asserting that the bill would weaken the U.S. Environmental Protection Agency's (EPA) 2014 coal ash rule. The signatories argue the legislation would delay health protections, eliminate public access to information, and remove national standards for drinking water protection, thereby increasing risks to vulnerable communities and the environment.

The report evaluates the vulnerability of North American monarch butterflies (Danaus plexippus) to climate change, identifying high sensitivity to temperature and a critical dependence on milkweed. While the species possesses high adaptive capacity due to dispersal ability and reproductive rates, it faces significant threats from habitat loss, pesticide use, and extreme weather. Recommended strategies focus on restoring milkweed and nectar sources, protecting overwintering forests in Mexico and California, and increasing population monitoring.

The Rocky Mountain forests are facing a "triple assault" of tree-killing insects, wildfires, and heat and drought, all driven by human-caused global warming. Bark beetle outbreaks killed trees on 46 million acres between 2000 and 2012, while large wildfires increased by 73 percent from 1984 to 2011. Iconic species like whitebark pines, aspens, and piñon pines are in catastrophic decline, with projections suggesting a 60 percent loss in suitable area for aspens by 2060 under medium-high emissions scenarios. The report argues that without reducing heat-trapping emissions and managing for resilience, these forests may be irrevocably degraded.

The forests of the Rocky Mountains are facing a 'triple assault' of tree-killing insects, wildfires, and heat and drought, all amplified by human-caused global warming. Bark beetle outbreaks killed trees on 46 million acres between 2000 and 2012, while large wildfires have increased in frequency and intensity. Iconic species like whitebark pines, quaking aspens, and piñon pines are in catastrophic decline. Projections suggest that if emissions continue unchecked, average regional temperatures could rise by 10°F by the end of the century, potentially replacing conifer forests with shrublands or grasslands. The report advocates for risk assessment, stakeholder engagement, managing for resilience, increasing agency capacity, addressing community vulnerability, and deep reductions in heat-trapping emissions.

The report details the expansion of solar energy in the U.S., focusing on rooftop photovoltaic (PV) systems, large-scale PV, and concentrating solar power (CSP). It highlights significant cost reductions, the role of state and federal incentives, and the environmental benefits of transitioning from fossil fuels to solar, while addressing grid integration challenges and land-use impacts.

The report argues that rising temperatures and drier conditions in the American West, combined with a trend of building homes in wildfire-prone areas, have led to longer fire seasons and soaring suppression costs. It highlights a misalignment of incentives where federal taxpayers bear the brunt of firefighting costs while local zoning allows risky development. The document details the broad economic impacts of wildfires—extending far beyond direct suppression to include public health crises, infrastructure damage, and tourism losses—and recommends a shift toward resilience, stricter building codes, and carbon emission reductions.

Margaret Bowman of the Walton Family Foundation outlines a vision for water resilience in the Colorado River basin to address a projected gap of 3.2 million acre feet between water supply and demand by 2060. The proposed strategy relies on three primary pillars: upgrading agricultural irrigation to save an estimated one million acre feet, implementing urban water efficiency programs to save another one million acre feet, and utilizing wastewater and stormwater recycling to gain 1.2 million acre feet. Bowman advocates for market-based water banking and targeted augmentation over large-scale water import schemes. She emphasizes the interdependence of urban and agricultural sectors and highlights the 2012 international agreement between the United States and Mexico as a model for cooperation, citing a recent pulse flow experiment in the Colorado River delta as an example of ecological and social co-benefits.

The Union of Concerned Scientists (UCS) evaluates the NRC's 2013 performance, noting a decrease in the number and severity of 'near-misses' but highlighting critical inconsistencies in enforcement. While the NRC successfully managed the restart of the Fort Calhoun plant and identified gaps in aging component oversight, it is criticized for allowing the Diablo Canyon and Oconee plants to operate despite known seismic and fire safety risks, and for improperly withholding information regarding the Jocassee Dam's potential to cause a total meltdown at Oconee.

The report identifies a significant range of estimated DPV values driven by differences in local context, input assumptions, and methodologies. While there is general agreement on estimating energy and capacity values, there is less consensus on grid support services and unmonetized values such as financial, security, environmental, and social risks. The analysis highlights that no single study comprehensively evaluated all DPV benefits and costs, and that costs associated with increased deployment are often inadequately assessed.

The document examines various energy storage technologies, ranging from established systems like pumped hydro and compressed air energy storage (CAES) to emerging solutions like flow batteries and flywheels. It highlights the critical role of U.S. federal initiatives, specifically Department of Energy (DOE) grants and Federal Energy Regulatory Commission (FERC) orders, in reducing financial risks and reforming market access to encourage utility-scale implementation. The brief also details specific U.S. projects and proposed legislation, such as the STORAGE Act, aimed at incentivizing storage to support grid stability and the integration of variable renewable energy.

The document examines various energy storage technologies, from established methods like pumped hydro to emerging battery and flywheel systems, highlighting their role in integrating renewable energy and stabilizing the grid. It details the impact of FERC Orders 1000 and 755 and DOE initiatives, such as the Joint Center for Energy Storage Research (JCESR), in reducing technical and economic hurdles. Additionally, it profiles several large-scale U.S. projects and discusses proposed legislation, including the STORAGE Act, aimed at incentivizing storage deployment through tax credits.

Wildfires in the Western U.S. are becoming more frequent and the wildfire season is lengthening, driven by regional temperature increases that are double the global average and earlier spring snowmelt.

The document highlights a trend of increasingly destructive wildfires in the U.S., driven by climate change and a lack of funding for hazardous fuel reduction. It notes that forests are shifting from carbon sinks to emitters and that the U.S. Forest Service faces significant budget cuts despite rising fire risks. The author proposes that developing markets for woody biomass and bioenergy could provide a sustainable funding mechanism for forest restoration and wildfire prevention.

The report analyzes the intersection of the U.S. electricity sector, water resources, and climate change, arguing that current power generation is vulnerable to water scarcity and high temperatures. Through modeling of four scenarios—Business as Usual, Renewables-and-Efficiency, CCS-and-Nuclear, and a general Carbon Budget—the authors find that a transition toward renewable energy and energy efficiency can drastically reduce both carbon emissions and water withdrawals and consumption. Conversely, low-carbon options like nuclear power and carbon capture and storage (CCS) remain water-intensive. The report provides a set of "water-smart criteria" for decision-makers to enhance the resilience of the U.S. power grid in a warming world.
