DOE research touches virtually every aspect of energy resources,
production, conversion, efficiency, and waste mitigation. A central goal is to
find ways to minimize the use of fossil fuels and maximize the use and
efficiency of renewable energy sources such as water; the sun; wind; ocean
waves, tides, and thermal energy; the earth’s heat; and biomass resources for
biofuels (www.eere.energy.gov). DOE also
seeks to generate, transmit, and use electricity and other energy sources much
more efficiently and with higher capacity; explore the use of hydrogen in fuel
and energy applications; develop clean coal technologies; optimize nuclear
energy plants, and harness fusion as a completely new, economically and
environmentally attractive energy source. (http://science.energy.gov/fes/
An international team of researchers, including three from Brookhaven National Laboratory, tracked nitrogen as soil bacteria pulled it from the air and released it as plant-friendly ammonium. This eco-friendly process -- called biological nitrogen fixation -- substantially promoted growth in certain grass crops.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
