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 Atlantic set a record on Saturday for the longest stretch of the hurricane season since the advent of satellites without a major named storm • Argentina is bracing for severe Zonda winds, a type of intense downslope gust unique to the eastern side of the Andes Mountains • While the wildfires darkening skies over Indonesia have receded, blazes are still raging across the southern shores of Sumatra, Borneo, and West Papua.

1. EPA plans to repeal climate rules on power plants

The United States is preparing to eliminate any cap on the amount of planet-warming pollution from burning coal or gas that power plants can spew into the atmosphere. On Sunday night, The New York Times reported that the Environmental Protection Agency planned to announce a final repeal of climate rules on the power sector at this week’s summit in Houston of energy ministers from the Group of 20 nations. The EPA already moved to remove the entire legal basis for regulating greenhouse gases at any level by gutting its endangerment finding, which my colleagues Robinson Meyer and Emily Pontecorvo explained last winter. In March, as I told you at the time, almost half of all U.S. states sued to block the administration from rescinding the finding. The EPA went on to scrap standards on climate-heating emissions for car tailpipes and loosened rules on heat-trapping chemicals used in refrigerators and air conditioners. Under the new proposal, which the Times noted would come out Monday, power plants would still face limits on mercury, arsenic, and other contaminants, “though the EPA has already loosened restrictions on how much mercury they can emit.”

New Englanders Will Pay Through the Nose to Stay Warm This Winter

Even the hardiest are shivering at the price of heating oil.

As leaves begin to turn from green to autumn hues of amber, gold, and brown, New England is preparing for an expensive winter.

While most of the country heats their homes with natural gas or electricity, about 5 million households — overwhelmingly located in the Northeast — use oil. Like diesel and gasoline (both of which have set price records recently) home heating oil is distilled from crude oil, which is currently trading at prices not seen since the early months of the war between the United States, Israel, and Iran.

Why a Climate Law Expert Sees ‘Small Glimmers of Hope’

Talking about the data center backlash, the midterm elections, and the future of renewables with Columbia Law School’s Romany Webb.

This week’s conversation is a quick catch-up with our friends at Columbia Law School’s Sabin Center for Climate Change Law. I hopped on the phone with the center’s deputy director Romany Webb to chat about recent updates they published to anti-renewables opposition analysis. I wanted to dig into their research beyond the toplines — what should people care about in the coming election? How have data centers come up in their research? Or the repeal of the Inflation Reduction Act?

The following conversation was lightly edited for clarity.
