Let's compare the @iea.org WEO2025 electricity mix projections for 2035 to 2024.
Solar soars in all scenarios!
But even the new Stated Policies scenario projects smaller increases in wind+solar, a smaller decrease in coal, and increased gas, compared to what IEA projected last year. 🔌💡

Listening to @volts.wtf recent panel/podcast with @mliebreich.bsky.social , discussing his "Pragmatic Climate Reset", published in two parts at BNEF last September.
Michael mentioned his "simplest energy model ever" - just 4 parameters - and I decided to sketch up and add emissions and temps.

Great article about the move-fast-and-break-things faction of the nuclear revival movement. Centered in Silicon Valley but with connections to Utah and Idaho. 🔌💡

This is a phenomenal long read. The sort of article it's incredibly difficult to get permission and resources to write nowadays.
bloomberg ran an absolutely killer investigation this week into the Silicon Valley + Koch/Abundance forces running the show on nuclear deregulation this year:

Finally some news about Utah's largest solar farm! 🔌💡
Says here it came online Sep 30 and they held a ribbon-cutting ceremony Nov 5. Not sure why they waited a month to make the announcement.

Paid a visit to Utah's nearly completed Faraday Solar Project. It'll be the largest solar farm in the state (>600MW) yet it's kinda under the radar, not yet listed at EIA or SEIA. Supposed to come online later this year and sell the power to Meta for its server farms. See alt-text for details. 🔌💡

I can't say how much of this article is accurate, but I do know the Sierra Club never had a "singular focus on climate change".
The Club's historical mission was to "explore, enjoy, and protect" public lands. Later it took on public health issues and eventually climate—rather awkwardly.

Looks like both of the incumbents have lost to their challengers in the Ogden city-wide council races—despite endorsements from the mayor and what's left of the local paper. Hard to say exactly why, but I'm glad we'll have some younger voices adding fresh perspectives.

"For many 25-year-olds living in their childhood bedrooms, moving to a single-family house would be entirely out of reach. What they need to make progress in their personal and professional lives is a small apartment in the place where their career and social opportunities are located."
Pro-housing voices from the right of center are increasingly focused on a "we need housing For Families" framing.
In a new column I explain why broad-based liberalization, especially for inexpensive types of housing, is important for helping people start families: www.governing.com/urban/to-sup...

Great reporting from Bryan!
Utah has no contribution limits, but Ogden enacted limits after a scandal in 2007, when Mayor Godfrey and his allies solicited contributions to a "nonprofit" from banks, hospitals, other businesses, even the Governor's office, then laundered the money into campaigns.

Read my latest story investigating how a political action committee tried to funnel $14K in campaign donations from an Arizona Christian nationalist pastor to an Ogden City Council candidate in a scheme to circumvent campaign contribution limits.

The federal government recently offered up thousands of acres for coal mining across Utah. But recent coal mining leases have failed to attract viable offers. So why is no one betting on coal, despite the Trump administrations push to boost the industry?
Despite Trump admin’s best efforts, interest in coal mining in Utah and across the West is falling flat

Wow. A lot of people I admire seem to have a visceral hatred for Bill Gates.
I read the whole memo and I honestly don't see what the big deal is. Lots of it is obviously correct. So what if you don't agree with every nuance?

The hierarchy problem (finetuning) of the Standard Model of particle physics is often presented as the question 'why the weak scale is so much smaller than the Planck scale'
But there is also a geometric interpretation that can be understood with little maths (but a lot of physics)
