Ecological and economic factors are prompting telecommunications companies to deploy energy-saving systems. The broadband DSL access network consumes about 20 billion kilowatt-hours of energy per year worldwide -- equivalent to four percent of Germany's annual energy consumption.
What if the future of greener, more sustainable energy solutions isn’t to be found in wind, solar, hydroelectric, and/or ethanol-based power, but instead lies in the efficient combustion of cellulosic biomass (e.g., wood chips, sawdust, switch grass, corn husks, pine needles, paper pulp, etc.) that can be used to create green electricity?
“Unlike oil and coal, power generated from biomass is cle
A solar energy research team from Valparaiso University’s College of Engineering will return to Switzerland this summer to continue testing the potential of harnessing the sun’s energy for industrial applications. Valpo, a member of the Council on Undergraduate Research, has been pursuing the research project since 2006.

Berkeley, CA -- Two researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), Evan Mills and Michael Wehner, contributed to the analysis of the effects of climate change on all regions of the United States, described in a major report released today by the multi-agency U.S. Global Change Research Program.
A new report issued today by the U.S. Global Change Research Program outlines the extent of climate change around the U.S. and its effects not only at present but for the future as well.
How much usable energy do wind turbines produce? It is a question that perplexes engineers and frustrates potential users, especially on windless days. A study published this month in the International Journal of Exergy provides a formula for answering this vexing question.
RICHMOND, Va. (June 15, 2009) -- A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' -- a stable cluster of atoms that can mimic different elements of the periodic table -- that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage.

400 years of discussion and we're still not sure what creates the Earth's magnetic field, and thus the magnetosphere, despite the importance of the latter as the only buffer between us and deadly solar wind of charged particles (made up of electrons and protons). New research raises question marks about the forces behind the magnetic field and the structure of Earth itself.
There won't be anymore waiting in the dark at this campus bus shelter. New flexible solar cell technology developed by a group of engineering researchers at McMaster University has been installed to power lighting for night-time transit users.
Trains, planes, buses and automobiles do not only effect the environment via their exhaust pipes. There is a full life-cycle of processes associated with getting from a to b that we rarely acknowledge.
GAINESVILLE, Fla. -- Sunflowers track the sun as it moves from east to west. But people usually have to convert sunlight into electricity or heat to put its power to use.
Now, a team of University of Florida chemists is the latest to report a new mechanism to transform light straight into motion -- albeit at a very, very, very tiny scale.
Approximately a third of the electricity consumed by large data centers doesn’t power the computer servers that conduct online transactions, serve Web pages or store information.
To harvest the wind: Cornell University will host “Large-Scale Wind-Generated Power,” a scientific workshop on gathering wind energy, June 12-13, 2009, at Hollister and Kimball halls on the Cornell campus.

Approximately a third of the electricity consumed by large data centers doesn't power the computer servers that conduct online transactions, serve Web pages or store information. Instead, that electricity must be used for cooling the servers, a demand that continues to increase as computer processing power grows.
