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:

The Chevy Bolt Is the Cheap EV We’ve Needed All Along

It’s not perfect, but pretty soon, it’ll be available for under $30,000.

Here’s what you need to know about the rejuvenated Chevrolet Bolt: It’s back, it’s better, and it starts at under $30,000.

Although the revived 2027 Bolt doesn’t officially hit the market until January 2026, GM revealed the new version of the iconic affordable EV at a Wednesday evening event at the Universal Studios backlot in Los Angeles. The assembled Bolt owners and media members drove the new cars past Amity Island from Jaws and around the Old West and New York sets that have served as the backdrops of so many television shows and movies. It was star treatment for a car that, like its predecessor, isn’t the fanciest EV around. But given the giveaway patches that read “Chevy Bolt: Back by popular demand,” it’s clear that GM heard the cries of people who missed having the plucky electric hatchback on the market.

Data Centers Have Solved Their Speed-to-Power Problem — With Natural Gas

“Old economy” companies like Caterpillar and Williams are cashing in by selling smaller, less-efficient turbines to impatient developers.

From the perspective of the stock market, you’re either in the AI business or you’re not. If you build the large language models pushing out the frontiers of artificial intelligence, investors love it. If you rent out the chips the large language models train on, investors love it. If you supply the servers that go in the data centers that power the large language models, investors love it. And, of course, if you design the chips themselves, investors love it.

But companies far from the software and semiconductor industry are profiting from this boom as well. One example that’s caught the market’s fancy is Caterpillar, better known for its scale-defying mining and construction equipment, which has become a “secular winner” in the AI boom, writes Bloomberg’s Joe Weisenthal.

Current conditions: A tropical rainstorm is forming in the Atlantic that’s forecast to barrel along the East Coast through early next week, threatening major coastal flooding and power outages • Hurricane Priscilla is weakening as it tracks northward toward California • The Caucasus region is sweltering in summer-like heat, with the nation of Georgia enduring temperatures of up to 93 degrees Fahrenheit in October.

1. Two deals worth billions highlight a bright spot for clean energy

Base Power, the Texas power company that leases batteries to homeowners and taps the energy for the grid, on Tuesday announced a $1 billion financing round. The Series C funding is set to supercharge the Austin-based company’s meteoric growth. Since starting just two years ago, Base has deployed more than 100 megawatts of residential battery capacity, making it one of the fastest growing distributed energy companies in the nation. The company now plans to build a factory in the old headquarters of the Austin American-Statesman, the leading daily newspaper in the Texan capital. The funding round included major investors who are increasing their stakes, including Valor Equity Partners, Thrive Capital, and Andreessen Horowitz, and at least nine new venture capital investors, including Lowercarbon, Avenir, and Positive Sum. “The chance to reinvent our power system comes once in a generation,” Zach Dell, chief executive and co-founder of Base Power, said in a statement. “The challenge ahead requires the best engineers and operators to solve it and we’re scaling the team to make our abundant energy future a reality.”
