Power grid upgrades may cause blackouts, warns Braess's paradox
Cause of LED efficiency droop finally revealed: Auger recombination responsible
(Phys.org)—Researchers at University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have conclusively identified Auger recombination as the mechanism ...
Thames Water, 2OC will deliver power from London's fatbergs
Materials scientists make solar energy chip 100 times more efficient
(Phys.org) —Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) have improved an innovative solar-energy device to be about 100 times more efficient than its previous ...
Energy from new Australian wind farms cheaper than from new coal or gas plants, report shows
'Invisible' particles could enhance thermoelectric devices
Thermoelectric devices—which can either generate an electric current from a difference in temperature or use electricity to produce heating or cooling without moving parts—have been explored in the laboratory ...
Jumping droplets help heat transfer
Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. ...
Sweden wants Norway's trash (and lots of it)
Thermoelectric material is world's best at converting heat waste to electricity
Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input ...
Glitch-hit US nuclear plant shut down for good
A California nuclear power plant shut down last year after a radiation leak will be permanently closed, its owners said Friday.
Nano-engineering boosts efficiency of materials that convert waste heat to electrical energy
High-performance thermoelectric materials that convert waste heat to electricity could one day be a source of more sustainable power. But they need to be a lot more efficient before they could be effective on a broad scale ...
Scientists determine activation barrier in ammonia-sulfuric acid clusters that could lead to cloud formation
(Phys.org) —Ammonia must overcome an energy barrier to join sulfuric acid and water to create clusters that can lead to cloud formation, according to scientists at Pacific Northwest National Laboratory ...
Morocco to harness the wind in energy hunt
Morocco is ploughing ahead with a programme to boost wind energy production, particularly in the southern Tarfaya region, where Africa's largest wind farm is set to open in 2014.
A storage power plant on the seabed
Norwegian research scientists will contribute to realising the concept of storing electricity at the bottom of the sea. The energy will be stored with the help of high water pressure.
