Side by side graphs of retail residential electricity prices vs. time for 3 big investor-owned utilities (left) and 2 big municipal utilities (right). The IOU prices rise from 10-15 c/kWh in 2010 to 30-40 c/kWh in 2024. The municipal prices stay nearly flat, ending at 11-18 c/kWh in 2024.

I knew municipal utilities generally provide lower electricity prices than investor-owned monopoly utilities, but I had no idea the difference was *this stark* in California. No wonder CA electeds are pushing to make municipalization easier and cheaper.

Dark money group offers influencers $1,500 for posts attacking Chicago Democratic primary candidate Progressive House candidate Kat Abughazaleh told MS NOW the secretive campaign is “filled with false and defamatory claims.”

HOLY SHIT.

A dark money group, hidden behind a bunch of shell companies, is paying influencers thousands of dollars PER POST to attack @katmabu.bsky.social on social media a month before her election.

Thank you to the people who declined the money and went forward with this. So who's behind this?

A question for the intel and defense people (or energy people who really know about this stuff) who might see this:

I have seen coverage that basically says you can't reopen the Strait of Hormuz without actually occupying the Iranian side. Assume that is true.

Do we have the boots in theater to put on the ground there? If not, how long would that take to put in place to actually reopen the straight? This seems like the worst case scenario, right?

If the Strait of Hormuz ends up closed for months, we're going to wish we took early action to ramp up EV production and sales, replace fuel oil with heat pumps, and deploy renewables as fast as we could (especially in regions that still rely on oil/dual fuel peakers for summer and winter peaks).

What’s worse?

Trump buying shoes that don’t fit and his Cabinet members being too scared to say anything. Or…

They haven’t figured out they can buy the same shoe in their size and he would never know. Or trade shoes with each other to wear the right size since they’re all the same style.

The enormous value to both Putin and Netanyahu of having an idiotic, compromised US president should also put his history with Epstein into sharp relief. Trump could be, or is, the greatest foreign intelligence success on the planet. Although if it's those two, his clients are as deranged as he is.

Radical change is now inevitable.

Copyright Jonathan Koomey 2026

#

On our current path, climate change threatens the continued orderly development of human
civilization. It will impose radical, rapid, and destructive effects on society if we don’t change
course immediately.

Alternatively, we can choose to make radical and rapid changes, reducing greenhouse gas
emissions to zero, ending fossil fuels, and creating a climate-positive biosphere.

Had we acted forty years ago when I first started working on the climate problem, we could
have made relatively modest changes to solve the problem, but we are out of time.

For more, see Stoddard et al. 2021. Three decades of climate mitigation: Why haven’t we bent
the global emissions curve? and Solving climate change: A guide for learners and leaders

@jgkoomey.bsky.social's message at our talk today should already define the knowledge you need to graduate from high school, and be the goal of the leadership skills taught in universities.

About this Book
Solving Climate Change grew out of a class Jonathan Koomey and Ian Monroe developed and taught at Stanford University titled “Implementing Climate Solutions at Scale”. It had as its primary goal teaching students quantitative and qualitative methods for understanding the rate and scope of change needed to truly face the climate challenge.  Students produced and presented a project for a state, region, or country that achieved net zero emissions by the middle of the twenty-first century, assessing potential emissions reductions and carbon removals in different sectors, based on the resources and characteristics of their chosen location, with some students going beyond net zero to net climate-positive.

This textbook introduces tools for understanding how to reduce emissions rapidly, hitting net zero emissions no later than 2040, then pushing beyond to remove carbon from the atmosphere and reduce carbon dioxide concentrations to those of the stable climate in which human civilization developed. We’ve written this book first and foremost as a resource for professors and students ready to teach and learn the key analytical tools needed to create a climate-positive world.

Jon's excellent textbook on solving climate, based on a class he and Ian Monroe taught at Stanford:

It really frustrates me how hard this is to explain: solar generates all at the same time across a region! Batteries definitely do help (charts to come) but even a big battery (this one's 22kWh) will sit full most of spring-autumn and nearly empty all winter.

I am not, by temperament, a gambling man. As a suburban dad with four kids, a mortgage, and a minivan, I’m more likely to be found wrestling a toddler into a car seat than scouring moneylines or consulting betting touts. And as a practicing Mormon, I am prohibited from indulging in games of chance. Besides, I had always thought of gambling as a waste of time. This makes me an outlier among my generational peers: Since 2018, Americans have wagered more than half a trillion dollars on sports, and roughly half of men ages 18 to 49 have an active account with an online sportsbook.

Trump has tremendous difficulty with principled people (even if as with the Iranian regime, the principles are bad). He assumes everyone is a transactional fraud like him. Works well with rich Americans and poorly with idealists of any stripe
