The Data Center Surge Has a Hidden Source of Carbon Emissions Tech companies are turning to green concrete to help reduce the massive environmental footprint of building out data centers.

Data center energy and water use have gotten a lot of (rightful) attention. But there's another issue that's getting less attention than it should: The immense amount of carbon-intensive concrete needed to build them πŸŽπŸ”—

What Democrats Can Learn From the Trump Energy Playbook Democrats shouldn’t be afraid to take more aggressive actions on clean energy, former Energy Secretary Jennifer Granholm said.

Jennifer Granholm's advice for Democrats: Implement their agenda as aggressively as Trump and tie building renewables to lowering energy bills.

Oh, and don't mention climate: β€œOn Maslow’s hierarchy of human needs, climate does not rise as much as how much I'm paying for my electricity bill" πŸŽπŸ”—

22GW of renewables thwarted or in limbo under Trump β€˜blockade’ An Interior Department memo is hampering wind and solar on public lands. It’s one of many federal actions slowing the build-out of cheap, clean energy.

Chaser: The administration has paused or canceled renewables projects on public lands that would be big enough to power 16.5 million homes

After the US admin cancelled the $B Climate + Weather Disaster dataset, @climatecentral.org hired the scientists who ran it and set it back up.

Now the 2025 numbers are in: it's 3rd highest year on record and highest year w/o land-falling hurricanes.
