The report argues that current U.S. distributed solar (DPV) business models are overly customer-centric and fail to capture operational grid benefits, leading to conflict between utilities and solar companies. It proposes three 'bridge' business model building blocks: increasing access via subscription models, optimizing deployment for capacity and grid services, and bundling solar with other distributed energy resources (DERs). The authors emphasize that maximizing DPV value requires collaboration to reduce 'soft costs' and a shift toward standardized valuation methodologies and transparent data sharing between stakeholders.

The report argues that traditional bundled, volumetric block rates are obsolete for a grid with increasing distributed energy resources (DERs) because they fail to reflect the temporal and locational value of electricity. It proposes evolving rate design along three continuums: attribute unbundling (separating energy and capacity), temporal granularity (moving toward real-time pricing), and locational granularity (addressing distribution 'hot spots'). The authors suggest a transition strategy using a combination of evolving default rates and opt-in alternatives, supported by third-party technologies to maintain a simple customer experience. Recommendations for regulators include increasing data transparency, enhancing valuation methodologies for DER attributes, and establishing clear timelines for rate transitions.

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 document outlines the systemic shifts required to integrate low-carbon energy, arguing that traditional power plant financing and grid structures are ill-suited for renewables.

The report highlights the vulnerability of iconic U.S. landmarks to climate-driven events. It details how sea level rise and storm surges threaten coastal sites like the Statue of Liberty and Jamestown, while increased heat and drought drive destructive wildfires in the West, affecting sites like Mesa Verde. The authors argue that climate resilience must become a national priority, requiring both resource allocation for site protection and a reduction in carbon emissions to mitigate future risks.

The report examines the vulnerability of iconic U.S. landmarks to climate change, highlighting risks such as sea level rise in coastal cities and increased wildfire activity in the Southwest. It argues for urgent national priority in climate resilience and carbon emission reduction to protect cultural heritage.

The document analyzes state green banks as quasi-governmental financial institutions designed to leverage public funds to increase private investment in clean energy and energy efficiency. It details the operational model of Connecticut's CEFIA, highlighting its use of credit enhancements and diverse financing tools to bridge the 'deployment gap' for commercially available technologies. The paper also reviews emerging green bank models in New York, Vermont, and Hawaii, while discussing the systemic benefits and drawbacks of state-level financing authorities.

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 analyzes the rise of atmospheric CO2, which reached a record high of over 400 ppm in May 2013, and discusses the resulting climate impacts and the necessity of immediate mitigation to avoid dangerous warming.

The United States is the world's largest importer of coral reef-associated species, with a market share of approximately 63% of global imports. Analysis of trade data from 2000 to 2009 reveals a five-fold increase in coral product imports and a steady annual import of roughly 15 million marine tropical fish. The report highlights the prevalence of destructive collection methods, such as cyanide use, and the overexploitation of specific species like the Banggai cardinalfish, seahorses, and giant clams. It argues that the U.S. should leverage its purchasing power to establish sustainability standards and improve data specificity to protect vulnerable marine ecosystems.

The document details the U.S. effort to reach a goal of one million electric vehicles by 2015 through the development of 'deployment communities' and infrastructure. It describes federal initiatives like the Transportation Electrification Initiative and Clean Cities, regional efforts such as the Northeast Electric Vehicle Network, and commercial fleet adoptions by companies like Frito Lay and General Electric. It also lists specific legislative proposals aimed at increasing consumer tax credits and funding for community deployment and fleet upgrades.

The document details US efforts to reach a goal of one million electric vehicles by 2015, focusing on federal, state, and local deployment programs, the role of commercial and government fleets, and proposed legislation to incentivize PEV adoption and infrastructure.

The document describes the technical operation of battery electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), noting that a range of 60 to 120 miles can satisfy the vast majority of daily travel needs. It details the 2012 U.S. market, highlighting the Chevrolet Volt and Nissan LEAF as dominant models and comparing specifications for several other vehicles. The text analyzes the economic impact of battery costs, the necessity of charging infrastructure, and the role of federal and state tax credits in making PEVs commercially viable.

The briefing examines the impact of the U.S. natural gas boom on renewable energy, noting that while low spot prices hinder utility-scale project financing in the near term, distributed solar PV and falling wind costs will sustain the transition.

The document explains how scenarios—depicted as maps of land cover or marine habitats—are used in InVEST to compare the delivery of ecosystem services under alternative futures. It outlines characteristics of effective scenarios, such as being plausible, legitimate, and scientifically credible, and provides a framework for converting narrative storylines into quantitative maps. Through case studies in Hawaii, Borneo, Tanzania, and Canada, the primer demonstrates how scenarios can inform integrated spatial plans, green economy policies, carbon project feasibility, and marine spatial planning.

The authors argue that the EPA's cost-benefit analysis for cooling water intake structures (CWISs) is fundamentally flawed due to the systematic underestimation of environmental benefits and the overestimation of costs. By incorporating a wider range of non-use values, correcting recreational value estimates based on the Bay Shore Power Plant study, and using revised cost estimates from Powers Engineering, the authors demonstrate that the most stringent regulatory options (Options 2 and 3) can yield positive net benefits. They further contend that the economic impact on electricity rates would be minimal and that stricter regulation would actually be more beneficial for national GDP and employment. Finally, they strongly oppose the use of site-specific calculations, suggesting instead a national standard with a higher threshold (e.g., 500 MGD) to protect smaller facilities while maintaining high environmental benefits.

The document examines the role of high-performance manufactured housing in providing sustainable, affordable housing in the U.S. It highlights the energy inefficiency of older mobile homes and proposes a shift toward an integrated design approach to lower operating costs and emissions. The brief outlines six key federal recommendations, including updating the HUD Code's energy standards and improving procurement specifications for disaster housing.

The author contends that nuclear power is uniquely dangerous and economically unviable compared to renewable energy. Using the Fukushima disaster as a catalyst, the text argues that nuclear plants are too slow and costly to effectively combat climate change, noting that private investment has shifted toward renewables. The author suggests that the global decline of nuclear power is driven by market forces rather than isolated accidents, and urges the U.S. and Japan to move toward a post-nuclear energy future.

The document provides a technical overview of nuclear containment, the process of reactor and spent fuel pool meltdowns, and the specific risks posed by radioactive isotopes like iodine-131 and cesium-137. It argues that U.S. nuclear plants share the same key vulnerabilities as the Fukushima reactors, particularly regarding power outages and spent fuel storage, and critiques the NRC's lack of requirements for new reactor designs to be demonstrably safer than existing ones.

The Clean Air Task Force criticizes the EPA's 'Boiler MACT' rule for weakening emission limits and failing to reflect best performers. The organization calls for the upcoming Power Plant Air Toxics Proposal to implement rigorous, state-of-the-art standards for utility steam generating units burning coal and oil, noting that the EPA and other bodies have sufficient data to regulate mercury, heavy metals, and acid gases.
