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/
A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.
Researchers from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have developed a manufacturing technique that could double the electricity output of inexpensive solar cells by using a microscopic rake when applying light-harvesting polymers.
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.
