Ocean waves can be powerful, containing enough energy to push around sand, pebbles and even boulders during storms. These waves, as well as smaller, more gentle ones, could be tapped as a source of renewable energy. Now, researchers reporting in ACS Nano have developed flexible power generators that mimic the...

Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and Colorado School of Mines are applying a new technique to identify defects in silicon solar cells that cause a drop in efficiency. The lessons learned at the atomic level could lead to improvements in the way manufacturers... Read more

Known by expectant parents as the technology that enables them to see their child for the first time, ultrasound can be used at extremely low frequencies to serve an entirely different purpose. Researchers at KTH Royal Institute of Technology in Sweden report the first ultrasound extraction of valuable metals from... Read more

Although research has been conducted into carbon capture and storage for 40 years, there is still a need to refine the technology to make it as energy efficient as possible. This is the case now, as carbon capture and storage has become an important element in the Danish government's climate... Read more

Dawdon coalmine in northeast England was abandoned three decades ago, but is being brought back to life as the unlikely setting for a green energy revolution.... Read more

After water levels at a California dam fell to historic lows this summer, the main hydropower plant it feeds was shut down. At the Hoover Dam in Nevada—one of the country's biggest hydropower generators—production is down by 25%. If extreme drought persists, federal officials say a dam in Arizona could... Read more

The summer of 2021 in Western Canada was one of the hottest on record. In BC alone, 59 weather stations registered their hottest temperatures ever on June 27.... Read more

When lithium ions are forced rapidly through a battery, they might get stuck and turn into lithium metal, no longer able to move through the battery.... Read more

Progress in applied research at Argonne National Laboratory raises hopes that solid-state batteries will replace conventional lithium-ion batteries sooner rather than later.... Read more

For a hybrid electric bus, Oak Ridge National Laboratory researchers have developed and demonstrated algorithm-based controls that yielded up to 30% energy savings compared with existing controls.... Read more

Fumbling to find flashlights during blackouts may soon be a distant memory, as quantum computing and artificial intelligence could learn to decipher an electric grid's problematic quirks and solve system hiccups so fast, humans may not notice.... Read more

The United Nations chief called Friday for the world to redouble its renewable energy efforts to avert a climate emergency and address global energy poverty.... Read more

Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and... Read more

Britain, which faces soaring natural gas prices, has been forced to run coal-fired power stations in order to secure energy supplies, electricity generation company Drax said on Thursday.... Read more

The tranquil landscape of flat farmland and small villages in the Essex countryside in southeast England seems a world away from Britain's escalating energy crisis.... Read more
