This fact sheet provides a comprehensive overview of the global offshore wind energy sector as of early 2016, contrasting the established European market with the emerging industry in the United States. It details the technical advantages of offshore wind over onshore wind, current installation capacities, key market players, and the economic and environmental impacts of the transition.

As of 2016, Europe dominated the global offshore wind market, with the UK, Germany, and Denmark leading in installed capacity. The United States, while possessing vast potential (over 4,000 GW), was in the early stages of deployment with its first commercial project at Block Island. The document highlights the technical advantages of offshore wind—such as stronger winds and proximity to coastal population centers—and notes the significant job creation potential in the EU sector.

This fact sheet provides an overview of fuel cell technology, detailing its operational mechanisms, various types, and its comparative advantages over internal combustion engines and batteries. It examines the technical and economic barriers to widespread adoption—specifically cost, hydrogen production, and infrastructure—while outlining current applications in portable, stationary, and transportation sectors. The document also analyzes the role of U.S. federal and state policies, including Department of Energy (DOE) initiatives and state-level incentives, in driving the commercialization and deployment of fuel cells.

A sign-on letter dated October 22, 2015, from a coalition of environmental, business, and public officials to President Obama, urging the federal government to make offshore wind a central part of the United States' clean energy strategy, specifically along the Atlantic coast.

A letter from the Attorneys General of New York, Delaware, Maryland, Massachusetts, Oregon, Rhode Island, and Vermont to the EPA urging the agency to regulate methane leaks from the natural gas distribution sector.

A joint statement from the Attorneys General of New York, Delaware, Maryland, Massachusetts, Oregon, Rhode Island, and Vermont urging the Environmental Protection Agency (EPA) to establish formal emission standards and guidelines for methane in the oil and gas sector following the publication of five technical white papers.

This report summarizes a 2011 workshop on climate adaptation for transportation, highlighting that local contextual data (e.g., infrastructure condition) is often more critical for decision-making than broad climate models. It identifies significant communication gaps between scientists and engineers, calls for a central information clearinghouse, and recommends updating engineering standards to move beyond historical data. Key needs include higher-resolution precipitation data, better economic tools for cost-benefit analysis of adaptation, and increased federal support for state and local capacity building.

The Stockholm Environment Institute critiques the EPA's cost-benefit analysis for cooling water intake regulations, arguing that monetized benefits are severely underestimated due to the exclusion of non-use values and errors in baseline mortality data. The authors suggest that when benefits are properly calculated and costs are reassessed, the regulations yield positive net benefits with minimal impact on electricity rates and a positive effect on employment and GDP. They strongly advise against site-specific calculations, recommending instead a national standard with a higher threshold for compliance.

A statement from the Environmental and Energy Study Institute advocating for a transition from petroleum to biofuels and biobased products to reduce national oil dependence, improve climate outcomes, and create jobs.

This fact sheet presents GIS-based estimates of populations in the conterminous United States living in coastal areas vulnerable to sea-level rise and storm surges, specifically those residing within 1 km of the coast or below 3 meters in elevation.

This fact sheet describes research by the Louisiana State University and the Inter-American Institute for Global Change Research (IAI) using GIS to estimate the population of the continental United States living in coastal areas vulnerable to sea-level rise and storms.

This report by the Environmental and Energy Study Institute (EESI) analyzes how state climate action plans in the United States incorporate land use, transportation, and green building policies as of July 2009. It finds that while transportation and green building are common, specific 'smart growth' land use practices are the least frequent component of these plans.

This fact sheet from the Environmental and Energy Study Institute (EESI) examines the energy inefficiency and poor living conditions of approximately 2 million mobile homes built before 1976 in the United States. It argues that because these structures are in such disrepair, they cannot be weatherized and must be entirely replaced with energy-efficient units to reduce carbon footprints and utility costs for low-income residents.

A statement by Norman Dean, Executive Director of Friends of the Earth, regarding the Supreme Court's decision to hear a case on whether the Bush Administration must regulate carbon dioxide emissions under the Clean Air Act.

This fact sheet describes the Long-range Energy Alternatives Planning System (LEAP), a software tool developed by the Stockholm Environment Institute for energy policy analysis and climate change mitigation assessment. It outlines the software's capabilities in integrated modelling, scenario analysis, and decision support, noting its widespread adoption by government agencies, academics, and NGOs in over 150 countries.

This report section details the use of economic incentives—specifically pollution charges, fees, and taxes—to protect the environment in the United States. It examines various instruments including water and air emission fees, solid waste disposal charges, product taxes, and specialized fees for wetlands and grazing, analyzing their roles in raising revenue and incentivizing pollution reduction.

This document is a fact sheet containing a table of individual green municipal bonds issued in the United States during 2017, detailing the issuers, amounts issued in USD, dates, project types, and CBI certification status.

This fact sheet details the distribution of American Recovery and Reinvestment Act (ARRA) grants for high-speed rail projects across four US regions: West, Midwest, Southeast, and Northeast, as well as additional planning awards.

This technical supplement describes the methodology used by RMI to analyze how state-level land use reform in the United States could reduce vehicle miles traveled (VMT) and greenhouse gas (GHG) emissions by 2033. The analysis compares a 'business as usual' scenario against a 'low VMT' scenario where new housing is concentrated in dense, walkable, and transit-oriented areas.

This report by the World Resources Institute provides a comprehensive guide for U.S. businesses on the deployment and financing of on-site renewable energy systems, including solar photovoltaic, solar thermal, wind, and geothermal heat pumps. It details the economic and financial benefits, various ownership and financing models, and the associated risks and objectives for corporate energy management.
