Energy systems and climate policy person with lots of opinions, few of which are wise to share. Total sucker for novel decarb pathways. Fanboy of functional democracies and a bit of grace.

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.

*correction, the LinkedIn post was September. I posted to Bluesky back in June

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.

FYI, difference in maps is that NYT uses summer 2018/2019 to summer 2024/2025.

Jeremy Fisher @jeremyfisher.bsky.social · 2d

Back in June, I posted in LinkedIn about the relationship between renewable energy and rates, with a snappy map. www.linkedin.com/feed/update/...
and I was amused, I guess, to see that map show up in today's print edition. Thanks NYT?

I was at the Sierra Club during the period described in this article and although I have my criticisms, it gets the issues in the Club fundamentally wrong. A 🧵

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.

Not too late to get in on the action, and join thousands of others as we dig into the impacts - and mitigations - for data center buildout. Join us on Wed at 7pm ET / 4pm PT.

Jeremy Fisher @jeremyfisher.bsky.social · Jul 31

🔌On Aug 20, I'll be hosting a public webinar exploring the scale of data center buildout, how utilities are reacting, and what policymakers and the public can do to protect health, rates, and our climate targets.

A big old bubble? 23 utilities are claiming more than 700 gigawatts of data center in their "economic development pipeline" - which smells a lot like a speculation boom. www.sierraclub.org/articles/202...

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?

We need attention on real issues, not smoke screens.
We need to ensure that large load customers, like data centers, are paying their own way.
We need to unlock low cost renewables that mitigate prices and fuel risk for everyone.
And we need to make tough decisions about living with climate change.

And now the very rapid rise of data centers and other very large load customers is having a very real effect on costs for customers as utilities scramble to build infrastructure.

In the West, the cost of mitigating - and paying for - wildfires spiked electricity costs along the coast, leaving both utilities and regulators grasping at next steps. autl.assembly.ca.gov/system/files...

In electricity markets like PJM and MISO, new generation projects - and particularly renewables - got stuck waiting for approvals, at an enormous cost to customers.

Coal prices followed suit, taking advantage of utilities that didn't have a lot of buffer. Together, both impacts cranked up energy costs across the US. But there was more to come.

Between 2021 & 2022, gas prices shot through the roof thanks to a perfect storm of post-covid rebound (demand increasing while supply lagged), massive exports, and a fully globalized commodity exposed to wartime uncertainty. And those higher costs were passed right through to ratepayers.

Jeremy Fisher @jeremyfisher.bsky.social · Jun 10

Jeremy Fisher @jeremyfisher.bsky.social · Jun 9

Here's the crazy part. While coal prices went up almost everywhere, coal prices in the eastern US - both Appalachia and Illinois basin - nearly doubled from 2021 to 2024, and Utah and Arizona coal plants both took huge step increases.

Jeremy Fisher @jeremyfisher.bsky.social · Jun 9

Great article from EI! Here's a companion dashboard showing that coal costs have gone up pretty much everywhere - and are staying up.
