When the Lights Go Out: Lessons from 2025's Blackouts and How to Prepare for What's Next

The recent power grid failures remind us that our modern way of life depends on infrastructure that isn't as reliable as we assume. The good news? A few thoughtful preparations can make all the difference.

On April 28, 2025, at 12:33 PM local time, something unprecedented happened in Europe. Within seconds, 60 million people across Spain and Portugal found themselves without electricity. Traffic lights went dark. Metro systems ground to a halt. Mobile networks failed. ATMs stopped dispensing cash. For nearly ten hours—and longer in some areas—the entire Iberian Peninsula experienced what EU experts would later call "the most significant power system event" in over two decades.

This wasn't a scenario from a disaster movie. It was a regular Monday afternoon.

What makes this event particularly significant is that it wasn't caused by a hurricane, earthquake, or cyberattack. According to the European Network of Transmission System Operators (ENTSO-E), the blackout resulted from voltage instability—a cascading series of generator disconnections that overwhelmed the grid's ability to stabilize itself. It was, remarkably, the first time rising voltage combined with generator disconnections had ever caused a blackout anywhere in Europe.

And if you think this is just a European problem, think again.

A Warning From the Department of Energy

On July 7, 2025, the U.S. Department of Energy released a report that should give every American pause. The findings were stark: if current trends continue—with power plants retiring faster than they're being replaced, and electricity demand surging from AI data centers and manufacturing—most regions of the United States will face unacceptable reliability risks within five years.

The numbers are sobering. The DOE projects that 104 gigawatts of firm generation capacity will retire by 2030, while only 22 gigawatts of new reliable, around-the-clock power is planned to replace it. The result? Annual outage hours could increase from single digits today to more than 800 hours per year in some regions—a hundredfold increase.

Meanwhile, electricity demand is growing at its fastest pace in decades, driven largely by data centers powering artificial intelligence applications, which could double their energy consumption by 2030.

Why Should This Matter to You?

The reality is that our power grid—whether in Europe or North America—is under more stress than at any point in modern history. The combination of aging infrastructure, increasing demand, extreme weather events, and the complex transition to new energy sources creates vulnerabilities that didn't exist a generation ago.

But here's the encouraging part: preparedness isn't about fear—it's about peace of mind. The families who weathered the Iberian blackout most comfortably weren't the ones with the most expensive solutions. They were the ones who had thought ahead and made sensible preparations.

The Three Pillars of Blackout Preparedness

When we look at what actually helps people during extended power outages, it comes down to three core needs: light, power, and communication. Let's explore each one.

1. Light: The First Comfort

When darkness falls unexpectedly, your first instinct will be to reach for light. Tragically, during the Iberian blackout, at least seven people in Spain and one in Portugal died from candle fires or generator exhaust fumes—preventable deaths that underscore why having safe lighting options matters.

For reliable, safe illumination during outages, consider battery-powered or rechargeable options. The XTAUTO Collapsible LED Camping Lantern 4-Pack ($29) offers an excellent solution—these lanterns feature both solar and USB charging, are water-resistant, and provide ambient light for entire rooms without fire risk.

For hands-free tasks—whether you're checking your electrical panel or preparing food in the dark—a headlamp is invaluable. The LHKNL Rechargeable LED Headlamp 2-Pack ($17) offers multiple lighting modes and motion sensor control, letting you navigate safely while keeping your hands free.

For a personal carry option, the Lighting EVER LED Flashlight ($9) provides high lumens in a compact, waterproof package and comes with batteries included.

And don't overlook the humble tea light candle for extended outages. The MontoPack Tea Light Candles 100 Pack ($14) provides 4-hour burn times and takes up minimal storage space—though always use them safely in proper holders, away from flammable materials, and never leave them unattended.

2. Power: Keeping the Essentials Running

During the Iberian blackout, one of the most immediate impacts was the loss of mobile communications. Without power to charge phones, people couldn't contact family, check on elderly relatives, or access emergency information. The lesson? Having backup power isn't a luxury—it's a lifeline.

For most households, the question isn't whether to have backup power, but how much. If your primary need is keeping phones, tablets, and small devices charged, a portable power station offers the most practical solution. The Anker SOLIX C1000 Gen 2 ($371) provides serious capacity with rapid recharging and the reliability of LiFePO4 battery technology—it can keep essential devices running for days during an extended outage.

For a truly off-grid charging solution that doesn't depend on the grid to recharge, the Anker 21W 2-Port USB Portable Solar Charger ($59) lets you harness sunlight to power your devices. When combined with a power station, you create a sustainable energy ecosystem that can keep you connected indefinitely.

3. Communication: Staying Informed

During the Spanish blackout, mobile networks failed as cell towers lost power. Many people found themselves completely cut off from information about what was happening and when power might return. The solution used for decades before smartphones still works: radio.

The RunningSnail Emergency Hand Crank Radio ($15) offers AM/FM and NOAA weather band reception, plus a built-in flashlight and 2000mAh power bank for charging devices. The hand crank means it works even when all your batteries are depleted—it's one of the few devices that can never run out of power as long as you have the strength to turn the crank.

Beyond the Basics: Practical Additions

Once you've covered the three pillars, consider these practical additions based on what actually helped people during recent outages:

For warmth in cold-weather outages: The Emergency Mylar Thermal Blankets 4-Pack ($5) reflects up to 90% of body heat and folds small enough to keep in a pocket. These aren't just for emergencies—they're peace of mind that weighs almost nothing.

For cooking without electricity: The Gas One Dual Fuel Portable Camping Stove ($29) works with both butane and propane, giving you flexibility in fuel sources. When your electric stove and microwave are useless, being able to heat water for coffee or warm up a meal transforms your experience during an outage.

For reliable fire starting: The 10lb Fatwood Fire Starter Sticks ($32) ignite even when wet—critical if you have a fireplace or wood stove for backup heating. Matches and lighters can fail; fatwood works.

For water safety: If a prolonged outage affects water treatment facilities, the LifeStraw Personal Water Filter ($16) can make questionable water safe to drink. It removes 99.9999% of bacteria and 99.9% of parasites, turning almost any water source into drinking water.

For vehicle emergencies: Power outages often coincide with severe weather, and you may need to drive to safety or help. The Everlit Car Emergency Kit ($59) includes an air compressor, first aid supplies, and essential roadside tools.

For versatility: The RAK 11-in-1 Multitool Pen 2-Pack ($19) and TECEUM 750lb Paracord ($9) may seem basic, but they've proven their worth countless times during emergencies—from quick repairs to improvised solutions you can't anticipate.

The Mindset That Matters Most

The DOE report is clear: grid reliability challenges are mounting. But here's what that same report makes evident—we're not helpless. The families who fare best during outages aren't necessarily the ones who spent the most money. They're the ones who thought ahead, made incremental preparations, and had a plan.

Consider starting small:

1. This week: Get a flashlight and a pack of batteries for each floor of your home
2. This month: Add a portable power solution and a way to charge it without the grid
3. This season: Build out your emergency kit with cooking, warmth, and water solutions
4. Ongoing: Keep your devices charged, maintain your supplies, and know where everything is

The Iberian blackout restored power to 99% of customers within about 18 hours—relatively fast for such a massive event. But many Americans have experienced outages lasting days or even weeks following severe storms. The question isn't whether you'll face a blackout, but when—and whether you'll be ready.

A Final Thought

There's something almost paradoxical about preparing for grid failures in our hyper-connected age. We carry more computing power in our pockets than existed in the entire world 50 years ago, yet we remain utterly dependent on an infrastructure that can fail in seconds.

The Iberian blackout wasn't caused by an extraordinary event—it was triggered by voltage variations that, according to grid operators, are "common in isolation." It was the combination of ordinary events that proved extraordinary. Similarly, the DOE's warnings about the U.S. grid aren't predictions of disaster—they're observations about math. Demand is rising. Supply is falling. Something has to give.

But here's the optimistic truth: you don't need to wait for someone else to solve this. The preparations outlined above are affordable, practical, and will serve you well whether the grid stays up or goes down. A power station charges your devices during camping trips and powers your home during outages. A solar charger works equally well at the beach and during an emergency. Emergency food tastes just as good on a hiking trip as it does during a blackout.

Preparation isn't pessimism—it's pragmatism. And in a world where even the most advanced power grids can fail on an ordinary Monday afternoon, a little pragmatism goes a long way.
