<p>This report was prepared by the Global Change Research Program (GCRP) in the National Center for Environmental Assessment (NCEA) of the Office of Research and Development (ORD) at the U.S. Environmental Protection Agency (EPA). It is intended for managers and scientists worki...

The evolution of the energy system in the United States is an important factor in future environmental outcomes including air quality and climate change. Given this, decision makers need to understand how a changing energy landscape will impact future air quality and contribute ...

Remedial actions taken to clean up hazardous waste sites for environmental restoration and potential reuse are often sources of diesel and greenhouse gas (GHG) emissions. Many remediation systems, such as pump-and-treat (P&T), may operate for many years, demanding electricity fr...

This report provides a general overview of EPA’s national MARKAL database and energy systems model and compares various scenarios to a business as usual baseline scenario. Under baseline assumptions, total electricity use increases 1.3% annually until 2030. Annual growth in ele...

Clean energy provides multiple benefits. The Multiple Benefits Guide provides an overview of the environmental, energy system and economic benefits of clean energy, specifically energy efficiency, renewable energy and clean distributed generation, and why it is important to thin...

This report quantifies the energy security benefits associated with reduced oil imports due to programs and policies.

The report describes an alternative mitigation process that would convert waste carbon dioxide (CO2) to carbon an methanol using natural gas as process feedstock. The process yields 1 mole of methanol from each mole of CO2 recovered, resulting in a net zero CO2 emission when the ...

The performance of an innovative heat pump, equipped with a distillation column to shift the composition of a zeotropic refrigerant mixture, was evaluated. The results of U.S. Department of Energy (DOE) rating tests and seasonal energy calcuations are reported with the main cycl...

The report gives results of a series of computer runs using the DOE-2.1E building energy model, simulating a small office in a hot, humid climate (Miami). These simulations assessed the energy and relative humidity (RH) penalties when the outdoor air (OA) ventilation rate is inc...

The report documents the 1995 Symposium on Greenhouse Gas Emissions and Mitigation Research, sponsored by the U.S. Environmental Protection Agency's Air Pollution Prevention and Control Division (EPA/APPCD), in Washington, DC on June 27-29, 1995. The symposium provided a forum of...
