US grid adds batteries at 10x the rate of natural gas in first half of 2024
By year's end, 96 percent of the US's grid additions won't add carbon to the atmosphere. (credit: DOE) While solar power is growing at an extremely rapid clip, in absolute terms, the use of natural gas for electricity pr.....»»
Canada to slap tariffs on EVs, steel from China
Canada, an export-driven economy that relies heavily on trade with the U.S., has been closely watching moves by the Biden administration to erect a much higher tariff wall against Chinese EVs, batteries, solar cells, steel and other products......»»

NASA"s DART impact permanently changed the shape and orbit of asteroid moon, new study shows
When NASA's Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid moon called Dimorphos in 2022, the moon was significantly deformed—creating a large crater and reshaping it so dramatically that the moon derailed from its ori.....»»
Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Unveiling the hottest period in a million years: The MIS 11c paradox
The hottest warm period in the past million years is believed to have occurred about 400,000 years ago. During this time, the Northern Hemisphere had less ice than today, and sea levels were about 10 meters higher. Surprisingly, solar radiation, a ke.....»»
