Listening to Saul on Volts comparing AUS vs US rooftop solar was painfully familiar. In AUS he got 5 quotes in 2 days + permit/interconnect in ~24h; here we’re DIY’ing our roof (with help from Bluesky friends like @commercialsolarguy.com) and permit review loop is the biggest bottleneck
Today on Volts: you've probably heard that Australia has cheap rooftop solar power. You've probably also heard some rumors & myths about it. (Is it destabilizing the grid?) I called my favorite Australian energy expert to clear it all up. This is a fun one!

Year 1 data on congestion pricing in Manhattan…
* Vehicle traffic: -11%
* Foot traffic: +3.4%
* Storefront vacancy: -0.9%
* Pollution: -22%
* Revenue for mass transit: $548M
So YES this has been a huge success.

really cannot be emphasized enough that bari weiss has literally never done journalism. i don’t mean that in the pejorative sense. i mean that in the “has never performed the job she was hired to do” sense
One explanation for Bari killing the story is that she did so as a public act of fealty to the administration. But another is that, as an inexperienced journalist, she doesn’t understand that a refusal to go on the record is a kind of comment in and of itself

It’s been a tough year for the climate movement. But while we may be down, we’re never out.
Especially with the news coming out of China that coal consumption in the power sector is on track for its first decline since the Paris agreement
That’s what I’d technically call a BFD 🤯

Revolutionarily good news that puts sunlight on track to be the leading energy source for people below 35º latitude, and either #2 or a slim plurality for people above that.

My plan to fix our utility bill crisis:
1) Free solar panels for anybody who wants them—lower rates even for people who don’t, stabilizing the grid, thousands of jobs
2) Make data centers pay their fair share
3) Tie utility executive compensation to rates—no bonuses for hikes
