Air & Radiation. Tools and links to technical information and to maps and charts pertaining to U.S. air pollution.

Biomass Program. This Department of Energy program develops technology for conversion of biomass to valuable fuels, chemicals, materials and power, in order to reduce dependence on foreign oil and foster use of biofuels.

Distributed Energy Program. This Department of Energy program supports cost-effective research and development aimed at lowering costs, reducing emissions, and improving reliability and performance of our nation's electric energy infrastructure.

Energy: EPA's Onsite Renewable Technologies. Many EPA facilities are using renewable technologies designed to capture and store energy from sun, wind, water, the earth's core, or biomass.

Fuel Cells and Vehicles. This site presents a fact sheet concerning fuel cells and their use in vehicles.

Fuel Cells: Assessing Cleaner Energy Technologies. While fuel cells promise to fill many energy needs while avoiding many problems, further study is needed to resolve remaining questions about their production and use.

Global Change Research Program. This assessment-oriented EPA program focuses primarily on understanding the potential consequences of climate variability and change on human health, ecosystems, and socioeconomic systems in the U.S. It assists EPA, communities, states, and others to investigate how to adapt to climate variability.

Global Warming: Climate. Human activities impact the chemical composition of the atmosphere through the buildup of greenhouse gases.

Solar Energy Technologies Program. The Department of Energy sponsors research and development that improves the performance and reduces the cost of solar technologies.

Transportation and Air Quality: Modeling, Testing and Research. This site provides links to transportation and air quality information related to estimating, testing for, and measuring emissions, as well as research on technologies for reducing emissions.

U.S. Global Change Research Program (USGCROP). This program supports research on the interactions of natural and human-induced changes in the global environment and their implications for society and the environment.
