Welcome to Climate 101

Your guide to the key technologies of the energy transition.

Welcome to Climate 101

Here at Heatmap, we write a lot about decarbonization — that is, the process of transitioning the global economy away from fossil fuels and toward long-term sustainable technologies for generating energy. What we don’t usually write about is what those technologies actually do. Sure, solar panels convert energy from the sun into electricity — but how, exactly? Why do wind turbines have to be that tall? What’s the difference between carbon capture, carbon offsets, and carbon removal, and why does it matter?

So today, we’re bringing you Climate 101, a primer on some of the key technologies of the energy transition. In this series, we’ll cover everything from what makes silicon a perfect material for solar panels (and computer chips), to what’s going on inside a lithium-ion battery, to the difference between advanced and enhanced geothermal.

There’s something here for everyone, whether you’re already an industry expert or merely climate curious. For instance, did you know that contemporary 17th century readers might have understood Don Quixote’s famous “tilting at windmills” to be an expression of NIMYBism? I sure didn’t! But I do now that I’ve read Jeva Lange’s 101 guide to wind energy.

That said, I’d like to extend an especial welcome to those who’ve come here feeling lost in the climate conversation and looking for a way to make sense of it. All of us at Heatmap have been there at some point or another, and we know how confusing — even scary — it can be. The constant drumbeat of news about heatwaves and floods and net-zero this and parts per million that is a lot to take in. We hope this information will help you start to see the bigger picture — because the sooner you do, the sooner you can join the transition, yourself.

This series was produced with the generous support of OER Project, which empowers educators around the world.


Without further ado, here’s your Climate 101 syllabus:

Q&A

Why the Wilderness Society Backs a Data Center Moratorium

Talking with Dan Hartinger, the land conservation group’s senior policy director.

The Q&A subject.

This week’s Q&A is with Dan Hartinger, senior policy director for The Wilderness Society, a prominent land conservation organization in D.C. that this week called for a moratorium on data center development on public land. The public statement was relatively scant on details about the group’s stance, and a decade of reporting on policy in Washington has taught me that its positions are quite influential, especially in more traditional outdoor recreation and conservationist circles that are also often bipartisan. So I reached out and asked if someone could further explain the society’s position, and Dan obliged.

The following chat was lightly edited for clarity.

Data Center Outrage Catches Up to Renewables Outrage in Michigan

Plus more of the week’s biggest development fights.

1. Central Michigan – I regret to inform you of this back-and-forth between candidates running for Congress and a would-be constituent because it’s a warning sign for the renewable energy sector (and sort of broke my brain).

  • This week brought the first and likely only debate between Rep. Tom Barrett and Sunrise Movement cofounder Will Lawrence, who are locked in a tight contest over the Michigan 7th congressional district. As I’ve written, their race is a must-watch not only for control of the U.S. House but also the political fortunes of the data center sector.
  • The debate contained a remarkable exchange: Moderators played taped remarks from Paula Caltrider, identified as “a local resident” in the city of Mason to ask the candidates a question about data centers. Instead, she offered a comment. “You know, you can’t be a part of this no data center movement without renouncing the large solar farms and dangerous battery storage facilities that power these data centers.” (Quick TL;DR on Caltrider: She’s been quoted in national media coverage of the data center backlash and last year won a legal settlement after allegedly being fired for refusing a vaccine mandate.)
  • Barrett then ran with Caltrider’s baton. “I appreciate Paula linking these together, the stripping away of local control that took place in pursuit of this Green New Deal agenda in Lansing that took away control from communities” – a reference to the state’s primacy law that other Michigan Republican candidates have opposed.
  • Lawrence, whose support for a federal data center moratorium made him a national political test case, did not take the bait, nor did he criticize renewable energy. Instead, this part of the debate became a tit-for-tat about whether the sitting congressman once backed tax breaks for data centers. “He stuck his finger up into the wind, saw which way it was blowing, did a complete 180 on this issue,” Lawrence said. Then Barrett and Lawrence got into a confusing back-and-forth about whether the Inflation Reduction Act was a giveaway to data centers.
  • To the best of my knowledge, this is the first time the Data Center Trojan Horse has reared its ugly head on any kind of prominent debate stage, but it won’t be the last. For example: The Wisconsin gubernatorial debate is Oct. 21, and we’ve warned you about that one.

2. Doña Ana County, New Mexico – I suggest you pay closer attention to the federal permitting fight playing out over Oracle’s Project Jupiter.

The Data Center Backlash Is Coming for Permitting Reform

The Senate’s compromise bill enters the chat at a moment when federal land and anti-pipeline advocates are already quite activated.

The AI data center backlash is getting louder in D.C. ahead of the midterms – and it’s poised to collide head-on with the new permitting reform deal being negotiated in Congress.

This week, major environmental advocacy organizations are taking large public steps to lean in on the data center fight. The League of Conservation Voters and Natural Resources Defense Council, I’ve been told, are imminently announcing a $250,000 ad buy in the Washington, D.C. market focused entirely on decrying fossil fuel-powered data centers and Trump administration policies to speed up their construction. The Wilderness Society, a prominent land conservation organization, announced it now supports a moratorium against data centers on “public lands” focused on the roughly half billion acres under the Interior Department’s stewardship. And Earthjustice on Thursday did a detailed report claiming that 80% of the data centers under development “bringing their own power” are going to rely on gas generation.
