A new facility will suck carbon dioxide from the air, showcasing the potential of a nascent industry that some say is crucial to fighting climate change

The Biden administration’s intention to use dozens of bombs’ worth of highly enriched uranium as fuel in a new civilian reactor sets a dangerous precedent, one that could help our foes get nuclear weapons

Virtual power plants are aggregations of electricity producers, consumers and storers that power grid managers can call on to balance electricity demand and supply

Powering artificial intelligence models takes a lot of energy. A new analysis demonstrates just how big the problem could become

Federal investment in carbon capture could help fight climate change, but this technology is facing fierce opposition

The rise and fall of LK-99 offers a lesson on how to consider technology’s role in urgently needed energy transitions

Hackers have already infiltrated electric vehicle chargers, usually for innocuous reasons, but bad actors could use that foothold to bring down the power grid

Nuclear fusion will scale up too late to avoid climatic catastrophe

Nuclear fusion won’t arrive in time to fix climate change, but it could be essential for our future energy needs

Here’s what’s next after the U.S. National Ignition Facility’s breakthrough on nuclear fusion last year
