First-ever global life cycle assessment of renewable energy future
A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study published in the today's Proceedings of ...
Energy storage of the future
Personal electronics such as cell phones and laptops could get a boost from some of the lightest materials in the world.
Researchers use real-world data to model the effect of more solar on the grid
American electrical utilities do a pretty fantastic job of getting us electricity when we need it. In 2006, the power was out on average for just 0.03 percent of the year in the United States. But right now, ...
New mechanism discovered to convert light into electricity: The 'plasmoelectric effect'
Researchers from FOM Institute AMOLF and the California Institute of Technology have discovered a new method for the generation of electrical potentials using light. With the help of minutely sculpted metal ...
Engineer says 'smart grid' needed for shift to alternative energy
(Phys.org) —Electrical grids are balky beasts, and nobody knows that better than Stanford Assistant Professor of Civil and Environmental Engineering Ram Rajagopal. He grew up in Brazil, where no one took ...
Perfect torque distribution for safe driving
A limiting factor for the driving range of electric vehicles is the amount of energy supplied by the batteries. To recoup as much braking energy as possible, engineers at the Gear Research Centre (FZG) at ...
After Fukushima, Japan gets green boom—and glut
Like other Japanese who were banking on this country's sweeping move toward clean energy, Junichi Oba is angry.
A novel platform for future spintronic technologies
Spintronics is an emerging field of technology where devices work by manipulating the spin of electrons rather than their charge. The field can bring significant advantages to computer technology, combining higher speeds ...
World's fastest manufacture of battery electrodes
New world record: Scientists at the Karlsruhe Institute of Technology (KIT) increased the manufacturing speed of electrode foils coated batch-wise by a factor of three – to 100 meters per minute. This was ...
'Reverse engineering' materials for more efficient heating and cooling
If you've ever gone for a spin in a luxury car and felt your back being warmed or cooled by a seat-based climate control system, then you've likely experienced the benefits of a class of materials called ...
Electric-car drivers trading gas for solar power (Update)
Owners of electric vehicles have already gone gas-free. Now, a growing number are powering their cars with sunlight.
French parliament votes to cut nuclear power reliance
Lawmakers in France, the world's most nuclear-dependent country, on Friday voted to cut reliance on the energy source from more than 75 percent to 50 percent within a decade.
Planned cut to renewable energy target 'a free kick' for fossil fuels
The federal government's plan to reduce Australia's Renewable Energy Target (RET) could jeopardise billions of dollars in investment while giving a boost to the fossil fuel sector, experts have predicted.
New system would allow programmers to easily trade computational accuracy for energy savings
As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption.
