Climate 101

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:

Current conditions: The East Coast’s Acela corridor is cooling down this week, with temperatures dropping from 85 degrees Fahrenheit in Philadelphia yesterday to the 60s for the rest of the week • Cape Agulhas is under one of South Africa’s Orange Level 6 warnings for damaging winds and dangerous waves • Floods and landslides in Brazil’s northern state of Pernambuco have left six dead and thousands displaced.


THE TOP FIVE

1. SEC moves to scrap climate rules — and quarterly reporting

The Securities and Exchange Commission has advanced a measure to formally end Biden-era climate disclosure rules for publicly-traded companies. The regulator sent the proposal to the White House’s Office of Management and Budget for review on May 4, according to a post on a government website first spotted by Bloomberg. The Wall Street watchdog’s 2024 disclosure rule mandated that publicly traded companies report on the material risks climate change poses to their business models, including the financial impact of extreme weather. Some large companies would have been required to disclose Scope 1 emissions, which are produced by the firm’s own operations, and Scope 2 emissions, which are produced by companies with which the firm does off-site business such as electricity. The rule had already been watered down before its finalization to remove Scope 3 emissions, which come from suppliers up and down the value chain and from customers who use a product such as oil.

Why John Arnold Is “Very Optimistic” Permitting Reform Will Pass This Year

Rob talks with the billionaire investor and philanthropist about how energy, Chinese EVs, and why he’s “very optimistic” that Congress will pass permitting reform this year.

If you work around climate or clean energy, you probably know about John Arnold. Although he began his career as a natural gas trader, Arnold has since become one of the country’s most important clean energy investors. He’s the chairman of Grid United, a transmission development firm undertaking some of the country’s most ambitious power line projects, and he is an investor in the advanced geothermal startup Fervo. He and his wife Laura run the philanthropic organization Arnold Ventures.

On this week’s episode of Shift Key, Rob talks with Arnold about the current energy chaos and what might come next. They discuss Arnold’s first trip to China, whether Congress might pass permitting reform this year, and what clean energy companies should learn from the fossil fuel industry.
