This weekend, the New York Times ran a story claiming Sierra Club’s values have diluted our mission. They couldn’t be more wrong. The list of their errors is too long for one social post, but we go over some examples in these slides.

The lesson is NOT that social justice will tear an organization apart. That's either a fundamental misunderstanding or an unspoken political agenda to maintain unjust systems. The lesson is that, like painting a room, most of the work is preparation.

I'm going to contend that DOE Sec Burgum's "capacity density" order is maybe the stupidest document ever leveled by that agency.
But, "based on common sense, arithmetic, and physics" what other metrics should we examine?
kWh per joule of insolation? tons of public land converted per MWh?

Yeah, it's true - the rates are just too damn high. Fuel cost spikes, wildfire costs, and slow interconnection are driving up electricity costs faster than inflation.

Kudos to AECJ for this clear-eyed investor resolution at Amazon.
Just for perspective, if AWS were a state, it would be the 35th largest electricity consumer *now*. And if we look at what's in the queue, its on its way to being the 20th largest, consuming more than states like OR, CO, or MA

"Real commitment would be a public plan with interim milestones to meet Amazon's net zero goals despite AI growth. Real answers mean no risks obscured, no solutions conflated or exaggerated...
It’s not just the future of the company that depends on it. All our futures depend on it."—Eliza Pan
First half of alt text: My name is Eliza Pan, and I’m an Amazon investor. I also worked at Amazon for 6 years. I’m here to point out a problem that Amazon execs have a blind spot about—Amazon’s fossil fuel-powered data center buildout. As investors, we need more information than management is giving us about how they’re handling these risks. I urge shareholders to vote for Proposal 7, requesting additional reporting on the impact of data centers on climate commitments. In 2019, after being pushed by its workers, Amazon made a climate pledge that was a big step forward—but still gravely inadequate. Every season, we see more fires, more heatwaves, more multi-billion dollar disasters—and in many countries the impacts are far worse. Given that the current administration has abandoned climate efforts, this is a moment when companies must decide if they truly want a sustainable future. AI is a climate disaster—Google and Microsoft’s carbon emissions have risen 30-50% as a result of AI growth. And Amazon? We don’t know; they won’t say. Amazon prefers a fog around the fact that data centers are a massive source of emissions—because data centers are also its biggest source of profit. Second half of alt text: Executives say they’re committed to the Climate Pledge. But in 2023, Amazon was dropped from the Science Based Targets Initiative, and is now listed as having its “commitment removed.” With no interim goals nor a science-aligned plan to reach net zero, investors need more information about how Amazon is meeting its targets. Even when data centers purchase renewable energy, they’re often displacing the use of that energy by households, rather than catalyzing new renewables. Real commitment would be a public plan with interim milestones to meet Amazon's net zero goals despite AI growth. Real answers mean no risks obscured, no solutions conflated or exaggerated. Andy Jassy, are you committed to the Climate Pledge? If you are, then Amazon needs to detail to investors how it will meet its climate commitments even as AI power demand is expected to double within 2 years, and to continue growing long past that. It’s not just the future of the company that depends on it. All our futures depend on it.

🤨I've been digging through utility IRPs, rate cases, and investor decks, and the total claimed "economic pipeline" of data centers in just 23 utilities is > 320 GW (!!) - that's like 2/3rds of US demand today.
I'm picturing a bunch of kids cheering that they're *definitely* going to win the lotto.
