California's gas generation has dropped, though not as much as some authors have claimed.
EIA: Between January and August 2025, utility-scale solar generation in California totaled 40.3 BkWh, nearly double the 22.0 BkWh over the same period in 2020. Meanwhile, natural gas supplied 45.5 BkWh of electricity, 18% less than during the same period in 2020: www.eia.gov/todayinenerg... 🔌💡

Utah's Intermountain Power Plant coal unit(s) still chugging along at ~500 MW, 2/3 of the way into the month in which they were, at last report, to be shut down (and replaced with two smaller gas units). Guess we'll see what happens on December 1. 🔌💡

In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

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. 🔌💡

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...

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?
