Radioactive water 'may have leaked' from Fukushima
Radioactive water may have leaked into the ground from a tank at the Fukushima Daiichi nuclear power plant, the operator said on Saturday, the latest in a series of troubles at the crippled facility.
New emissions standards would fuel shift from coal to natural gas
Tougher EPA air-quality standards could spur an increased shift away from coal and toward natural gas for electricity generation, according to a new Duke University study. Complying with stricter regulations on sulfur dioxide, ...
Global solar photovoltaic industry is likely now a net energy producer, researchers find (w/ video)
(Phys.org) —The construction of the photovoltaic power industry since 2000 has required an enormous amount of energy, mostly from fossil fuels. The good news is that the clean electricity from all the installed ...
Anxiety about retirement—for aging nuclear power plants
Mention "high costs," "financing" and "safety" in the same sentence as "commercial nuclear power plants," and most people think of the multi-billion-dollar construction or operational phase of these facilities, ...
Fully renewable electricity could be competitive
(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.
The virtual power plant: Stable supply of electricity from renewable energies
A conglomerate of many smaller power plants can replace traditional power plants. The research project Combined Power Plant 2 (Kombikraftwerk2) shows how it is possible to provide power using renewable energies both today ...
Harvesting unused energy with flat thermoelectrics
A large proportion of the energy we produce disappears unused into thin air via waste heat. Tiny thermoelectric generators can tap this potential, whereby the electricity is produced by way of temperature ...
Hybrid ribbons a gift for powerful batteries: Vanadium oxide - graphene material works well for lithium-ion storage
Hybrid ribbons of vanadium oxide (VO2) and graphene may accelerate the development of high-power lithium-ion batteries suitable for electric cars and other demanding applications.
When energy-saving becomes a game
(Phys.org) —A smartphone application bringing gaming dimensions to energy awareness has helped householders in Finland, Sweden and Italy reduce their electricity consumption by up to 19%.
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 ...
Cooling systems restored at Fukushima reactors, TEPCO says
Technicians have restored power to all cooling systems at the reactors of Japan's tsunami-hit Fukushima nuclear plant, the operating company said Wednesday after a blackout sparked a new crisis.
Crippled Japan nuclear plant hit by power cut
Engineers at Japan's crippled Fukushima nuclear plant partially succeeded Tuesday in restarting cooling systems after a power cut underlined its still-precarious state two years after a tsunami struck.
Solar storm near Earth caused by fast CME
On March 17, 2013, at 1:28 a.m. EDT, the coronal mass ejection (CME) from March 15 passed by NASA's Advanced Composition Explorer (ACE) as it approached Earth. Upon interacting with the giant magnetic bubble ...
