How to Prepare for a Blackout: Complete Survival Guide 2025
The Great Blackout of 2025: A Lesson for Europe and a Call for Smart Preparation
In Northvivor We know that the blackout that affected much of Europe in April 2025brought together millions of people.
Within minutes, Spain, Portugal, Italy and parts of Francewere without power due to a cascading failure in the European grid.
Trains stopped, hospitals running on generators, communications cut off, and supermarkets collapsed were just some of the scenes that played out for hours.
Beyond the technical impact, the blackout exposed an uncomfortable truth: we are not prepared to live without electricity, even for a day.
This article does not seek to alarm, but Inform and prepare. Because massive blackouts—whether caused by technical failures, cyberattacks, or extreme weather events— are becoming more frequent.
And the best defense against uncertainty is intelligent prevention.
Understanding Risk: Why Blackouts Are No Longer a Exception
Europe has one of the most developed electricity grids in the world, but also one of the most interdependent.
This means that a failure in one country can affect several countries in a matter of seconds.
Factors that increase the risk include:
-
Overload of the electrical systemduring heat waves or extreme cold.
-
Cyberattackson critical infrastructure.
-
Severe weather events, fires or floods.
-
Dependence on intermittent renewable sources(wind and solar).
In such a scenario, personal energy resiliencebecomes a necessity, not an option.
💬 Preparing isn't about fear, it's about taking responsibility. 
What to do before a blackout: preventive preparation
Preparation begins long before the lights go out.
Your goal should be to be able to maintain your autonomy—energy, nutrition, and emotional—for at least 72 hours without external assistance.
🔹 Key steps:
-
Have a self-contained lighting source:tactical flashlights, safe candles, or solar-charged LED lights.
-
Ensure access to drinking water:store containers or use portable filters.
-
Store non-perishable foods:canned goods, energy bars, nuts, etc.
-
Prepare anemergency kit :basic medication and first aid.
-
Have an alternative means of communication:battery-powered or dynamo-powered emergency radio.
-
Have auxiliary power:external batteries or solar power banks.
-
Define a family meeting point:in case the networks go down.
Pro tip:Practice your own shutdown protocol.
A quarterly review of your kit can make all the difference.

During a blackout: stay calm and execute the plan
When the electricity goes out, serenity is your best tool.
The first 30 minutes are often confusing. Therefore, having a clear plan and an accessible survival kit reduces the psychological and logistical impact.
Recommendations:
-
Do not use candles near curtains or flammable materials.
-
Unplug appliances sensitive to electrical surges.
-
Ration your cell phone battery and avoid unnecessary calls.
-
Keep the refrigerator closed as much as possible.
-
Inform (if possible) vulnerable family members or neighbors.
A power outage is an opportunity to test your emotional and logistical management skills under pressure.
After the blackout: Evaluate and adjust your preparation
When the power comes back on, the mission is not over.
Evaluate what worked and what didn't: Did your flashlight hold a charge?Does the water last long enough? Were any items missing?
This review allows you to improve your personal protocoland strengthen your independence for future emergencies.
Resilience is not built in a day, but in every review, every adjustment, every improvement.

Frequently Asked Questions About Blackouts
How long can food last in the refrigerator without electricity?
A closed refrigerator keeps food cold for approximately 4 hours. A full freezer can maintain the temperature for up to 48 hours if closed, while a half-full freezer lasts for approximately 24 hours.
Is it safe to use candles during a power outage?
Candles can be used, but always with caution. Place them on stable surfaces, away from flammable materials, and never leave them unattended. LED lanterns are a safer alternative.
What do I do if I have medical equipment that requires electricity?
If you rely on electrically powered medical equipment, contact your electric company to register as a priority customer. Consider investing in a backup generator or emergency battery specifically for medical equipment.
Should I unplug all appliances during a power outage?
Yes, it's a good idea to unplug sensitive electronic devices like computers, televisions, and household appliances to protect them from potential power surges when the power is restored. Leave a light on so you know when the power is back on.
How much water should I store for emergencies?
It is recommended to store at least 3 liters of water per person per day, for a minimum of 3 days. This covers hydration and basic hygiene needs.
Can I use the barbecue indoors during a power outage?
Never use charcoal or gas barbecues indoors or in enclosed spaces. They produce carbon monoxide, a toxic, odorless gas that can be fatal. Use them only outdoors in well-ventilated areas.
How can I charge my phone without electricity?
Use a pre-charged power bank or external battery, a portable solar charger, or your car charger. It's important to always keep these backup devices charged.
Being prepared for a power outage doesn't require a huge investment, but it does require planning and common sense. With these tips and your emergency kit ready, you can handle any power outage with peace of mind and safety.
