Wet computer server could cut internet waste
A revolutionary liquid-cooled computer server that could slash the carbon footprint of the internet is being tested at the University of Leeds.
Renewables can fill 80 percent electricity demand in U.S. in 2050
'Hybrid' nuclear plants could make a dent in carbon emissions
Many efforts to smooth out the variability of renewable energy sources—such as wind and solar power—have focused on batteries, which could fill gaps lasting hours or days.
Using nanophotonics to reshape on-chip computer data transmission
A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able ...
Japan to be nuclear-free as last reactor switched off
Japan on Sunday began switching off its last operating nuclear reactor for an inspection, with no date scheduled for a restart amid strong public hostility towards atomic power.
Research shows greater potential for solar power
Concentrating solar power (CSP) could supply a large fraction of the power supply in a decarbonized energy system, shows a new study of the technology and its potential practical application.
Japan nuclear-free as last reactor switched off
Japan went nuclear-free on Monday as it switched off its last operating reactor for an inspection, with no date scheduled for a restart amid strong public hostility to atomic power.
Wind farms can provide society a surplus of reliable clean energy, study finds
The worldwide demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40 percent a year on average, and the installed capacity of wind ...
Study reveals the give and take of urban temperature mitigating technologies
Life in a warming world is going to require human ingenuity to adapt to the new realities of Earth. Greenhouse-gas induced warming and megapolitan expansion are both significant drivers of our warming planet. ...
German bank reports solar power cost in India and Italy has reached grid parity
Scientists develop cheaper, more efficient fuel cells
(Phys.org) —Using the Canadian Light Source (CLS) synchrotron, researchers have discovered a way to create cheaper fuel cells by dividing normally expensive platinum metal into nanoparticles (or even single ...
Why the renewable target should be ramped up, not cut
It's hard to predict which of Australia's climate policies will survive, or perhaps even thrive, in the current parliament. But our research suggests that if the Abbott government wants to cut long-term power ...
New report outlines how network technology must increase efficiency to meet rising energy demands
The collective power consumption of core networks is outpacing technological advancements in energy efficiency, putting a strain on growth in the IT and telecommunications industry—and potentially on global ...
Taking biofuel from forest to highway
The world is moving from a hydrocarbon economy to a carbohydrate economy, according to University of British Columbia biofuel expert Jack Saddler. He is presenting his work at the 2012 Annual Meeting of the American Association ...
