Amazing to see solar generate a record 39% of California’s electricity from January through July. www.canarymedia.com/articles/sol...

Solar is crushing gas power in California this year

The state’s combination of solar and battery plants has pushed clean generation of electricity to new heights, offering a welcome reprieve from high gas…

And when we try to make changes, neighbors organize with rhetoric like this. Kemp Mill Civic Association is riling up fear of having to pay tickets (avoidable by not speeding) while people are killed on these roads. It’s disgusting.

What are we even doing here, Caltrans? An $11B project that will result in status quo or worse VMT. It accepts climate change as real, and then totally ignores one of the prime causes.

This state needs a complete reboot when it comes to transportation planning.

Caltrans has released a cross section for the ultimate (raised viaduct) version of SR-37.

Now maybe I'm just being paranoid, but if you were building a road that you planned to keep at 4 lanes wide, I don't think it would look like this.

Cross section of 114' wide bridge structure with each direction having a 12' outside shoulder and a 10' inside shoulder.

This is right next to the NY Supreme Court, and Jay St / Metrotech. Illegally parked cars, day after day, worsening pedestrian and bike safety.

Council Member Lincoln Restler @cmrestler.bsky.social · 1d

Our office released a new study highlighting rampant illegal parking across Downtown Brooklyn. Vehicles block sidewalks, crosswalks, bike lanes & loading zones - making it more dangerous for New Yorkers to get around the neighborhood.

Since foreign students typically pay full freight this will raise tuitions or cut aide to American students

International student arrivals to the US dropped 19% this year, the biggest drop on record aside from the 2020 pandemic low.

The Upshot @upshot.nytimes.com · 2d

The decline is occurring as the Trump administration has delayed visa processing, instituted travel bans or restrictions for 19 countries, threatened to deport international students for pro-Palestinian speech, and heightened the vetting of student visa applicants.

As Trump doubles down on a violent, fossil fuelled vision of US hegemony, China dominates all of the industries that underpin the renewables revolution, reshaping global politics. theconversation.com/goodbye-petr...
