Mathematical formula boosts renewable energy efficiency
A mathmatical framework for rating transmission lines aims to help relieve power grid congestion to make more efficient use of renewable energy.
Off-grid German village banks on wind, sun, pig manure
If Germany has taken a pioneering though risky role in shifting to renewable energy, then the tiny village of Feldheim—population 150—is at its vanguard.
CERN: World-record current in a superconductor
In the framework of the High-Luminosity LHC project, experts from the CERN Superconductors team recently obtained a world-record current of 20 kA at 24 K in an electrical transmission line consisting of two ...
Researchers suggest wild animals avoid power lines due to UV light emittance
Work on Africa's biggest wind farm in Kenya to begin

Scientists develop new materials for board-level photonics
Today at the Photonics West conference, Dow Corning and IBM scientists unveiled a major step in photonics, using a new type of polymer material to transmit light instead of electrical signals within supercomputers ...
Connecting dead ends increases power grid stability
Climate change mitigation strategies such as the German Energiewende require linking vast numbers of new power generation facilities to the grid. As the input from many renewable sources is rather volatile, ...
Juiced roads: Volvo explores electric power for trucks, buses
'Third World' power outages plague US homes, firms
The United States is the biggest economy in the world, but all it takes to put the lights out here is some snow, or wind, or rain, or squirrels, even a prison break-out.
The science behind northern lights
(Phys.org)—Northern night skies have recently been alive with light. Those shimmering curtains get their start about 93 million miles away, on the sun.
With changes, the grid can take it
Over the next two decades, the U.S. electric grid will face unprecedented technological challenges stemming from the growth of distributed and intermittent new energy sources such as solar and wind power, ...
European to capsule leaving space station, skipping test
A European cargo ship is set to depart the International Space Station this weekend. But it will re-enter the atmosphere and burn up the next day, skipping a special descent test because of a problem.
