Iran’s Cheap, Plentiful Weaponry Puts US Military Under Unprecedented Strain As the conflict extends towards a third week, an arsenal of attack drones and ballistic missiles has helped make Tehran unlike any adversary the US has faced.

The US has burned through over 1,000 Patriot interceptors ($4 million each) to stop an onslaught of Iranian drones ($20k to $50k each).

Using my last gift link from Bloomberg, which is doing some of the best reporting anywhere on the war.

BREAKING: A judge refused to block a Kansas law that invalidates the driver’s licenses of transgender people and allows trans people to be sued for using public restrooms.

This isn't the final say, and we will keep fighting in court to stop this discriminatory law.

What if I told you that Transportation is the highest-polluting sector of the American economy?

Now what if I told you that ~100% of that is from oil?

Now what if I further told you that we can do something about it but mostly aren't even trying?

As someone who once co-authored two books in support of nuclear energy: this is likely the kiss of death to nuclear power.

It is a risky long term investment that is uniquely dependent on social acceptance. An incompetent, very unpopular government slashing safety rules leads to a reaction.

Australian Court Finds Context Is King in Clearing Oil Company Santos of Greenwashing Last month Australian courts cleared oil company Santos of greenwashing over claims it produced β€œclean energy’. Subsequently, fossil fuel companies demanded a β€œcrack down” on green groups.

ICYMI oil and gas companies in Australia used this very odd ruling in a greenwashing case to push for stripping all climate orgs of the right to sue 🀯 @roycerk2.bsky.social reports drilled.media/news/santos-...

A dispatch from the annals of Project 2025 authoritarianism: Universities are now being required to provide demographic data on all students who applied to their schools for the past 5 years so the feds can sniff out illegal affirmative action. Until last year, tho, keeping such data was not allowed

If you want to beat them, figure out how to organize a bloc of economic actors whose material interests are served by the transition. Organize a bloc with *more power* and then *defeat* them. That's how this works. You're not going to fucking seduce them with your clever verbiage!

California to see unprecedented heat wave in coming days Temperatures 30 degrees above normal are expected in parts of California as a startling weather event unfolds over the next 10 days.

California's already poor snowpack is going to further shrink in the coming week as an unprecedented heat wave strikes the state.
Remember how to use #water carefully.

As Californians electrify, can this tech combo prevent grid overload? Utility PG&E is piloting two devices that strategically throttle power use so that new EVs and heat pumps don’t mean costly home and grid upgrades.

California utility PG&E is testing how self-throttling home power controls from startup Span and grid-balancing smart meter controls from Itron can help customers install more EVs and heat pumps without costly grid upgrades. Here's how it works: www.canarymedia.com/articles/uti...

A food bank cut costs with solar. A local Goodwill noticed. After a North Carolina nonprofit put up rooftop solar, a nearby Goodwill headquarters did too, a move that will save energy and boost a job training…

Love to see more non-profits installing solar to cut costs and further their mission. Sad that the IRA direct pay credits that made this possible were killed. We managed to leverage those for three nonprofits locally.

Hard to believe that we're 10+ years into this and "Trump says..." is still treated as news without the need for any additional context, such as the fact that he has a history of saying a whole lot of things, most of which don't make sense.

A Big Night Light in the Sky? Start-Up Wants to Launch a Space Mirror.

I was interviewed by @nytimes.com about Reflect Orbital's terrible idea to use giant space mirrors to illuminate Solar farms.

The numbers are crazy. They'd need 3000 satellites to provide 20% of the midday Sun to just one solar farm. And they want to charge $5000 per hour per satellite!

I'm not sure if the average Dem or even the average climate type has really caught on to the fact that ALL the big money guys in DC are absolutely banking on a huge renaissance of natural gas demand. They are looking at more gas, more pipelines, more more more, with no upper limit. They're giddy.
