Eclipses inspire awe, create opportunities for science — and cause angst among energy-grid operators.
Today, millions of people will gather to marvel at the total solar eclipse.
The awe that eclipses inspire is profound. “You suddenly feel as though you can see the clockwork of the solar system. Where you think you lived doesn’t look like the same place anymore,” Ernie Wright, who creates data visualizations and eclipse maps for NASA, told Vox.
“We kind of know — in the back of our minds — that we live in a giant ball and it revolves around a hot ball of gas, and we’re floating in space. But you don’t really believe it until you see something like a total solar eclipse, where everything is all lined up and you go whoaaa.”
But that same power that inspires awe can also be seriously disruptive to — and sometimes scary for — life on Earth.
For some communities in the path of totality, tens of thousands of out-of-town eclipse-seekers are set to generate upward of $1 billion in revenue across numerous cities, from Austin, Texas, to Rochester, New York. Though lucrative, many places are girding for water shortages, sewage and garbage issues, and horrendous traffic.
The eclipse could also disrupt the US energy grid, threatening potential brownouts and blackouts in some areas of the country.
Solar eclipses aren’t just spectator events; they’re also an opportunity to study our solar system and our energy systems at home.
Solar power, eclipsed
As my colleague Umair Irfan reports, the United States currently has more than 139 gigawatts of solar electricity generation capacity. That’s more than two and a half times the amount of solar that was on the grid during the last total eclipse in 2017. The upcoming eclipse will also shade a path twice as wide as the last one. Though much of the country will see some decline in solar power production, the biggest fall will be directly under the moon’s shadow.
For the most part, power grid operators aren’t too worried about outages or major problems during the eclipse. They saw this coming and planned for it. Unlike disruptions such as clouds, the moon passing between the Earth and the sun is easily predictable up to 1,000 years in advance.
Behind the scenes, though, it will require a carefully choreographed series of energy transactions to precisely ramp up electricity from a handful of generators and route it across hundreds of miles of transmission lines to millions of customers to precisely match the needs of every monitor, air conditioner, and light bulb the instant they turn on.
What they learn during this totality will prove useful as even more intermittent power sources connect to the grid. Power generators and transmission systems face even more severe stresses from rising energy demand and threats like wildfires, drought, and storms, many worsened by climate change.
Texas provides a good example: It has the second-largest solar capacity in the US and the path of the totality cuts straight through it. According to the National Renewable Energy Laboratory, the state is projected to see a nearly 60 gigawatt drop in solar power production when the eclipse passes over.
The Texas grid operator, ERCOT, has been running simulations and modeling how the eclipse will affect the state’s power network, which, unlike the rest of the continental US, has few connections to other states. That means it can’t easily buy or sell electricity across state lines if it has too much or (in this case) too little power.
But for an ordinary power user — someone like you — it’s unlikely you’ll notice anything about your electricity during the eclipse. Some utilities might have to scramble to secure extra power, but that won’t manifest at the outlet.
Phew.

Are there other people working to prevent Earthly disruptions?
Eclipses are a rare moment to observe the solar corona, the sun’s outer atmosphere that can be observed radiating from the eclipsed sun’s outer edges, and the dynamic of solar weather, which can wreak havoc on life on Earth. Radiation from solar storms often ends up hitting the planet, which can lead to beautiful phenomena like the northern lights. But it can also cause massive problems, like energy grid disruptions, major blackouts, or even taking down satellites.
Despite how much damage solar storms can do to our tech on Earth, scientists are still struggling to predict them. And that’s because they don’t understand everything about how the corona works. Even though it extends far out from the surface of the sun into freezing cold space, the corona is still a million degrees hotter than the surface of the sun. And scientists aren’t sure why.
This is why Shadia Habbal, a professor of solar physics at the University of Hawaii, became an eclipse chaser.
“We have some clues [about solar storms],” Habbal told Noam Hassenfeld on a recent episode of Vox’s Unexplainable. “We know what’s causing them, but we can’t predict when they will happen. And that’s one of the things we’re trying to gather: some more information from our eclipse observations.”
When is the next eclipse?
A total solar eclipse happens somewhere in the world about every 18 months. The next one will be on August 12, 2026, and it will pass over Spain, Iceland, and Greenland. The one after that? August 2, 2027, over North Africa.
NASA keeps a catalog of all the eclipses (both solar and lunar) that have occurred or will occur from 1999 BCE to 3000 CE. Check that calendar and you’ll see that the next solar eclipse over the United States will be visible in Alaska in 2033. For the lower 48? 2045.
See you then.

From a “Department of Life” to a “future regime” led by Christian men, their ideas could have an outsize influence on Trump’s policies.
As president, Trump delivered for anti-abortion voters in the biggest way possible by appointing the three Supreme Court justices who cast the deciding votes to overturn Roe v. Wade.
Rather than campaigning on that gift to the anti-abortion movement this year, however, he’s largely running away from it — no doubt because pro-abortion-rights candidates and measures have been consistently winning since Roe fell.
In voicing his (potential) support for a 15-week federal ban on the procedure, Trump also said the issue should be left to the states, and that activists pushing for stiffer federal bans should understand that “you have to win elections.”
Endorsing a 15-week ban (which would be very unlikely to pass Congress) is Trump’s way of telling moderate and independent voters that “he’s not going to make abortion an issue,” said Mary Ziegler, a law professor at UC Davis and author of the book Abortion and the Law in America: Roe v. Wade to the Present.
Indeed, part of Trump’s success in the polls thus far appears to stem from his ability to capture independent voters who are dissatisfied with the economy and angry about immigration, but who may not identify as religious or even as conservative. It’s plausible that Trump might let abortion politics — and issues of reproductive and family policy more generally — fade into the background in a second term. After all, it’s “not something he instinctively cares a lot about,” said Matthew Wilson, a political science professor at Southern Methodist University.
However, there are powerful groups within Trump’s coalition — both his base of supporters and his stable of former and current advisers — who do care a lot about abortion. And contraception. And gender identity. And marriage.
Trump’s message to these groups, cloaked in religious language, is much different from the one he’s delivering to moderates. And they’re likely to have an outsize influence on policy in a second Trump term, in part because Trump has few social policy positions of his own.
Understanding those actors is key to predicting how he and his surrogates might govern in 2025, if they get the chance.
The Heritage Foundation and other conservative think tanks
The Biden campaign in recent weeks has directed a lot of attention toward Project 2025, a kind of super-team of conservative think tanks and interest groups tasked with creating a playbook for “the next conservative administration.”
Led by the Heritage Foundation, the project includes on its advisory board both old-line anti-abortion groups like Susan B. Anthony Pro-Life America (once Susan B. Anthony List) and groups like the Claremont Institute, which rose to prominence during Trump’s presidency. The playbook itself, titled Mandate for Leadership: The Conservative Promise, is more than 800 pages long and includes chapters on how the next conservative president (Trump is not mentioned by name) should overhaul the Departments of Justice and Health and Human Services (HHS). Some of its prescriptions:
- Rescinding FDA approval of mifepristone, one of the drugs used in medication abortion (something a Trump-appointed HHS secretary could do without approval from FDA scientists, Ziegler has written).
- Prosecuting people who send abortion pills by mail using the Comstock Act, a little-known 1873 law banning the mailing of “obscene, lewd, lascivious, indecent, filthy or vile” materials. (This would cut off one of the only pathways for getting an abortion in red states.)
- Promoting a “family agenda” that states that “men and women are biological realities” and “married men and women are the ideal, natural family structure.” The document also recommends that HHS “install a pro-life task force” and “return to being known as the Department of Life,” a nickname introduced under Trump.
The Trump campaign has not acknowledged Mandate for Leadership as any kind of playbook. “All 2024 campaign policy announcements will be made by President Trump or members of his campaign team,” campaign officials said in a November statement. “Policy recommendations from external allies are just that — recommendations.”
“Project 2025 does not speak for President Trump or his campaign,” a spokesperson for the project told Vox in an email.
Nonetheless, many of the authors of Mandate are members of the first Trump administration who would likely have roles in a second.
Roger Severino, the author of the HHS chapter, was the director of the HHS Office for Civil Rights under Trump, a role in which he oversaw the removal of nondiscrimination protections for LGBTQ Americans in health care settings. Gene Hamilton, the author of the Justice Department chapter, served in Trump’s DOJ and Department of Homeland Security and worked on the “zero tolerance” immigration policy that separated children from their parents at the border.
“These are all people that, in theory, Trump listens to,” Ziegler said.
When it came to abortion policy in Trump’s first term, “he delegated,” Ziegler added. Odds are he would do so again, and Project 2025 gives some clues about how and to whom.
Trump’s first presidential campaign “did not have a blueprint” for governing because “they did not believe they could win,” said Mini Timmaraju, president of Reproductive Freedom for All (formerly NARAL Pro-Choice America). Trump was still able to stack the court system to wipe out the federal right to an abortion and “completely gut and in some ways remake federal agencies.”
“That was with no prep,” Timmaraju said. “I take these guys incredibly seriously.”
Anti-woke influencers
While some in the Republican coalition work on plans to ban abortion pills, others are continuing the battle against what they’ve branded as liberal “woke” culture, including protections for LGBTQ Americans and efforts toward diversity, equity, and inclusion (DEI).
This group includes a newer, more unpredictable part of the conservative ecosystem: the podcasters and influencers who could turn out votes for Trump in 2024, from Joe Rogan to the Nelk Boys. These voices speak directly to young men who might not go to church or think that much about abortion policy, but who can maybe be persuaded that Democrats are waging a war on men and that Donald Trump can stop them.
This constituency is dear to Trump’s heart — he and Donald Trump Jr. have both appeared on the Nelk Boys’ podcast, and he has anointed Nick Adams, an over-the-top Australian influencer who calls himself “the Godfather of the ‘Alpha King’ movement,” by writing the foreword for his book.
There’s also plenty of overlap, ideologically, between think tanks and anti-woke influencers. Anti-trans rhetoric and policy recommendations crop up throughout Mandate for Leadership, whose foreword proclaims that “children suffer the toxic normalization of transgenderism with drag queens and pornography invading their school libraries.” The document also calls for deleting the terms diversity, equity, and inclusion from every federal rule as part of a drive to “make the institutions of American civil society hard targets for woke culture warriors.”
Meanwhile, conservative activists see an opening around “woke” culture issues, especially since other right-wing social positions, like opposition to abortion, are politically unpopular. They’re looking at polls showing that majorities of Americans support restrictions on gender-affirming medical treatments for minors and trans women participating in women’s sports, Wilson said (though a majority also support prohibitions on discrimination against trans people).
While Trump doesn’t actually care much about religion, he does love stoking culture wars, so his personal interests are perhaps more aligned with the anti-woke crusaders than with old-line evangelical abortion opponents. All this suggests that trans rights and DEI could remain fixations for him and his party in a second term.
Christian nationalists
A third group that’s influential for Trump on social issues is the Christian nationalist movement, whose adherents believe “the U.S. is a Christian nation and that the country’s laws should therefore be rooted in Christian values,” according to NPR. More than half of Republicans supported these views in a 2023 PRRI/Brookings survey, and the ideology counts among its adherents Rep. Marjorie Taylor Greene (R-GA), who has said, “I am a Christian and I say it proudly: We should be Christian nationalists.”
The idea that American laws should be rooted in Christianity isn’t new on the right, but some observers are concerned about the extent to which Christian nationalists today prioritize their worldview over democracy. The Society for American Civic Renewal (SACR), for example, a group open only to straight Christian men who hold supportive views of Trump, has discussed an “aligned future regime” stocked with loyalists, Josh Kovensky writes for Talking Points Memo.
SACR’s founder, Charles Haywood, has speculated openly about his role in a potential civil war, writing that he might serve as a “warlord” in “conditions where central authority has broken down,” such as “more-or-less open warfare with the federal government, or some subset or remnant of it.”
Abortion comes up frequently as a touchstone for Christian nationalist groups, said Kristin Kobes Du Mez, a professor of history and gender studies at Calvin University who studies religion and politics. “I have seen that issue surface in explicitly Christian nationalist spaces as a reason to jettison democracy,” Du Mez told Vox.
Christian nationalists were heavily involved in the January 6 Capitol riot, experts say, with four of six protest permits issued that day going to groups with links to the movement. Adherents remain some of Trump’s most committed supporters, said Laura Field, a political theorist and scholar in residence at American University. “Some of them talk about him as a new Cyrus” — a Persian king referenced in the Old Testament who did not worship the Jewish God but nonetheless carried out God’s plans, Field said.
Trump speaks directly to such supporters in prayer-style closings of recent campaign speeches, promising, “we are one movement, one people, one family and one glorious nation under God.” He has also leaned into the legacy of January 6, calling the date of the insurrection a “beautiful day” and playing a song at rallies sung by incarcerated participants, whom he calls “J6 hostages.”
While it’s unclear how much of the vision (or visions) held by Christian nationalists could realistically come to pass in a second Trump administration, it is clear that these groups now represent, to a great degree, Trump’s base, one he’s been courting zealously on what he hopes is his second journey to the White House.
There’s a lot of overlap between the think-tank world, anti-woke influencers, and Christian nationalists. Ryan P. Williams, president of the Claremont Institute, is also a board member of SACR. And the male supremacist ethos of the anti-woke podcasters fits right in with the tenets of Christian nationalists, who often see men as the rightful heads of both household and state.
But perhaps the biggest area of overlap lies in approach. Post-Dobbs, anti-abortion forces have undergone a reinvention, becoming “a movement less focused on winning over the public and more focused on exercising power through the executive and the courts,” Ziegler said.
That determination to push through unpopular policies through consolidation of power runs through Mandate for Leadership and through the ideas of Christian nationalist groups as well.
It’s a reminder that while Trump does need to pay attention to public opinion during his campaign — hence his (sometimes) careful language around issues like abortion — a big part of his appeal as a candidate and the leader of a movement is his perceived ability to flout public opinion and do whatever he and his most loyal supporters want.
Don’t worry if you missed the 2024 eclipse. There will be more.
Total solar eclipses like the one crossing America today are beautiful, but they’re fleeting. Totality, when the sun is completely covered by the moon, lasts just a few minutes. And the whole thing — from the start of the partial eclipse to the end — takes just a few hours. The experience is sublime, but it’ll leave you wanting more.
Here’s the good news: Total solar eclipses happen somewhere in the world about every 18 months. That’s how long it takes for the specific conditions that create eclipses (the phases of the moon, the distance of the moon to Earth, and the moon crossing the plane of Earth’s orbit) to line back up.
The next total solar eclipse will be on August 12, 2026, and it will pass over Spain, Iceland, and Greenland. The one after that? August 2, 2027, over North Africa.
NASA keeps a catalog of all the eclipses (both solar and lunar) that have occurred or will occur from 1999 BCE to 3000 CE.
That’s why we know, for instance, that on January 27, 2837, a total solar eclipse will pass over southern Mexico. (Will any humans be around to see it?)
The next solar eclipse over the United States will be visible in Alaska in 2033. And the next one in the lower 48 states will be in 2045.
