This policy brief examines the funding crisis facing the U.S. Highway Trust Fund (HTF), noting that federal fuel taxes have not been adjusted since 1993. It details the resulting infrastructure deterioration, the reliance on General Fund transfers to maintain solvency, and various proposed solutions including inflation indexing, fuel tax increases, and vehicle miles traveled (VMT) fees.

This statement from the Environmental and Energy Study Institute argues that U.S. forests are increasingly transitioning from carbon sinks to carbon emitters due to climate change, droughts, and wildfires. It highlights a critical funding gap for hazardous fuel reduction and ecosystem restoration, suggesting that expanding markets for wood products and bioenergy could provide a sustainable financial model for forest management.

This research paper by the Climate Policy Initiative (CPI) evaluates the effectiveness of residential building energy codes in the United States from 1986 to 2008. Using econometric analysis of state-level energy consumption data, the study finds that building energy codes are associated with a reduction in primary energy use and greenhouse gas emissions per household, while also influencing fuel choice by shifting consumption toward natural gas and away from other fuels like fuel oil.

This policy brief from the Environmental and Energy Study Institute examines the potential for high-performance manufactured housing to provide sustainable, affordable housing in the United States. It highlights the energy inefficiency of older mobile homes, the advantages of factory-built construction, and recommends federal actions to update energy standards and improve financing options.

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.

The Center for International Environmental Law (CIEL) comments on the testing of cold-resistant genetically modified eucalyptus trees in the Southern US, using the controversy over 'gene flow' to argue for the restoration of the Office of Technology Assessment (OTA) to provide independent scientific evaluations of climate-related technologies.

This report by the Environmental and Energy Study Institute (EESI) examines the state of the advanced biofuels industry in the United States following the 2008 economic recession. It analyzes national policy trends, identifies critical barriers to commercialization—including technological hurdles, market volatility, and regulatory uncertainty—and provides ten specific policy recommendations for state governments to support sustainable, local biofuel development during periods of limited fiscal capacity.

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 research paper by Andreas Spiegel of Swiss Re argues for a balanced climate adaptation strategy that combines cost-effective risk prevention measures with risk transfer mechanisms, such as insurance. Using data from the Economics of Climate Adaptation (ECA) working group, the author demonstrates that a significant portion of climate-related losses can be averted through preventative action, while residual risks should be managed via public-private partnerships and innovative financial instruments to protect vulnerable economies, particularly in developing nations.

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) details the employment potential of renewable energy (RE) and energy efficiency (EE) sectors globally and within the United States. It compiles various studies and reports to argue that clean energy transitions can provide quality, long-term jobs and economic growth, contrasting these trends with the decline of traditional fossil fuel employment.

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.

This 2009 fact sheet by the Environmental and Energy Study Institute (EESI) examines the potential of unharvested crops and food processing waste as biomass feedstocks for biofuels. It argues that these resources can provide renewable energy and chemicals without competing with food production, highlighting specific waste streams from the potato, orange, and tomato industries and the economic benefits of recycling these materials.

A 2009 fact sheet by the World Resources Institute detailing energy consumption sources, electricity generation, and greenhouse gas emission trends in Florida based on 2005-2008 data.

This 2009 fact sheet from the World Resources Institute provides data on energy consumption, electricity generation, and greenhouse gas (GHG) emissions trends in Mississippi, based on 2006 and 2005 data.

This 2009 fact sheet from the World Resources Institute provides data on energy consumption, electricity generation, and greenhouse gas (GHG) emissions in Virginia, based on 2006 and 2005 data.

This fact sheet from the World Resources Institute outlines the renewable energy generation potential in Florida, comparing various power resources across economic and environmental metrics and proposing policy priorities to increase renewable electricity adoption.

A fact sheet detailing the potential economic, employment, and environmental benefits of implementing a national energy efficiency resource standard (EERS) in Florida.

This briefing by the World Resources Institute examines the interdependent relationship between water and energy resources in the Southeastern United States. It highlights how electric power production relies heavily on freshwater for cooling, while water treatment and heating require significant energy, proposing policy priorities to improve efficiency in both sectors.
