In 2022, President Biden signed the Inflation Reduction Act, ushering in, by some estimates, nearly half a trillion dollars of investment in green energy and manufacturing. But what will happen to this huge investment as Donald Trump enters office?

Jigar Shah is one of the best people to answer this question. As the director of the Loan Programs Office at the Department of Energy, he has spent his career finding new ways to finance green infrastructure. And he’s more optimistic than you might expect about the road ahead.

In this conversation, guest host Robinson Meyer, a contributing writer for New York Times Opinion and the founding executive editor of Heatmap News, asks Shah for a progress check on decarbonization. They discuss what has changed about the economics and financing of clean energy; what has worked well in the green energy transition, as well as the trade-offs it has entailed; and what may or may not change as Trump enters office.

Donald Trump will enter office at a time when presidential power has significantly expanded, because of a string of Supreme Court decisions in recent years. These decisions can be understood to have two functions: They give presidents a “sword” to act more decisively and unilaterally, and a “shield” that protects them from prosecution against actions taken in their official capacity. What will these capacities mean for Trump’s second term — especially as he has promised to radically transform the federal government?

Gillian Metzger is a professor at Columbia Law School who has studied the presidency, the administrative state and the Supreme Court’s relationship to both. In this conversation, guest-hosted by Kate Shaw, a New York Times Opinion contributing writer and law professor, Metzger discusses two key Supreme Court cases — the Trump immunity case, which gave presidents broad protections from prosecution, and the Loper Bright Enterprises case, which overturned the Chevron doctrine, expanding judicial power. Shaw and Metzger also cover how much leeway Trump actually has to take some of the bolder executive actions he’s floated, including ending birthright citizenship; what still remains uncertain about the federal government’s regulatory powers in the post-Chevron regime; and more.

This election felt like the peak of the TV-ification of politics. There’s Trump, of course, who rose to national prominence as a reality-TV character and is a master of visual stagecraft. And while Trump’s cabinet picks in his first term were described as out of central casting, this time he wants to staff some positions directly from the worlds of TV and entertainment: Pete Hegseth, his choice to run the Pentagon, was a host on “Fox and Friends Weekend”; his proposed education secretary, Linda McMahon, was the former C.E.O. of W.W.E.; Mehmet Oz, star of the long-running “The Dr. Oz Show,” is his pick to run Medicare and Medicaid; and he’s tapped Elon Musk, one of the most powerful figures in American culture, to lead a government efficiency effort. 

Two years ago, we released an episode that helps explain why politics and entertainment are converging like this. It’s with my old Vox colleague Sean Illing, host of “The Gray Area,” looking at the work of two media theorists, Marshall McLuhan and Neil Postman, who uncannily predicted what we’re seeing now decades ago.

And so I wanted to share this episode again now, because it’s really worth stepping back and looking at this moment through the lens of the media that’s shaping it. In his book “The Paradox of Democracy,” Illing and his co-author, Zac Gershberg, put it this way: “It’s better to think of democracy less as a government type and more as an open communicative culture.” So what does our communicative culture — our fragmented mix of cable news, X, TikTok, YouTube, WhatsApp and podcasts — mean for our democracy? 

This episode contains strong language.

Every Tuesday and Friday, Ezra Klein invites you into a conversation about something that matters. How do we address climate change if the political system fails to act? Has the logic of markets infiltrated too many aspects of our lives? What is the future of the Republican Party? What do psychedelics teach us about consciousness? What does sci-fi understand about our present that we miss? Can our food system be just to humans and animals alike?
