When the Power Goes Out: Are You Ready for 72 Hours Without Electricity?

Whether It’s July in Arizona or February in Colorado, Here's What Happens When the Grid Fails—and What You Can Do to Prepare

Imagine it’s a blazing hot July afternoon in Arizona. The sun is relentless, temperatures soar above 110°F, and suddenly… the power goes out.

Or picture a frigid February night in Colorado. Snow is piling up outside your window. You’re warm and comfortable—until everything goes dark and the heat cuts off.

Now imagine this power outage doesn’t last a few hours. It lasts three days. Maybe longer.

Are you ready?

Most people aren’t. In fact, most people haven’t even considered it.

In a hyper-connected world where comfort is a given and digital payments are the norm, we’ve become so dependent on “always-on” infrastructure that the idea of being without it is hard to even picture. But it happens. And increasingly often.

Here’s the uncomfortable truth: the grid isn’t invincible.

Wildfires, winter storms, cyberattacks, heat waves, overloaded systems—any of these can trigger a prolonged outage. When that happens, the question isn’t if it’ll affect you. It’s how long can you function without it?

The First Few Hours: Minor Inconvenience or Major Problem?

When the lights first go out, it’s easy to shrug it off. Maybe you light some candles, grab your phone flashlight, and wait. But depending on the season, your location, and your resources, things can escalate quickly.

In Hot Climates (e.g., Arizona in July):

• Indoor temps can climb dangerously fast, especially without ventilation.
• Air conditioning is gone. So is refrigerated food.
• Phones die quickly if you don’t have backup charging.
• You’ll sweat out your water stores—but there’s a problem with that too… keep reading.

In Cold Climates (e.g., Colorado in February):

• Temperatures plummet inside your home.
• Pipes can freeze and burst.
• Your heat source vanishes, unless you have a wood stove or gas fireplace.

What Actually Stops Working During a Power Outage?

We often assume it’s just the lights and appliances, but it goes far beyond that. Here’s a list of critical systems and services that could fail:

1. Payment Systems

• No credit cards, no ATMs. If you don’t have cash, you can’t buy.
• Gas stations, grocery stores, and pharmacies can’t process payments—or even open.

2. Water Systems

• Most water relies on electric pumps to reach your house.
• No power = no water pressure. You might lose access to drinking water, toilets, and showers.
• Hot water? Forget it. Your electric water heater is useless.

3. Food Storage

• Your refrigerator starts warming up within 4 hours.
• A full freezer holds for about 48 hours (24 if half full).
• After that, hundreds of dollars in food could spoil.

4. Heating & Cooling

• Without grid power, most HVAC systems stop.
• If you rely on electric heat, your home will get cold fast.
• If you rely on A/C, it can become dangerously hot—especially for the elderly, children, or pets.

5. Medical Devices

• CPAP machines, oxygen concentrators, insulin storage—all depend on power.
• If you or a loved one relies on one, this is a critical failure point.

Three Days Without Power: What Does It Really Look Like?

By day three, you're no longer just inconvenienced. You're surviving. Here’s what you could be dealing with:

• Toilets that won’t flush.
• No way to cook unless you have gas, a BBQ grill, or camping gear.
• Melting freezers and spoiled food.
• No Wi-Fi, no updates, and no way to check in on loved ones.
• Complete reliance on what you already had on hand.

And if you live in an apartment or a densely populated area, things get worse fast: elevators are out, security systems fail, and indoor temperatures can be lethal.

So What’s the Plan? Here’s How to Be Ready

Being prepared isn’t about stockpiling like a doomsday prepper. It’s about having basic, functional resources in place to stay safe, comfortable, and calm for at least 72 hours. Here's how.

✅ 1. Have Water—Lots of It

• Store at least one gallon of water per person per day.
• Keep extra for pets, hygiene, and cleaning.
• Consider purification tabs or filters like LifeStraw or Berkey.

✅ 2. Create a Non-Perishable Food Stash

• Canned goods, jerky, protein bars, rice, beans, dried fruit.
• Don’t forget a manual can opener.

✅ 3. Store Cash

• Keep small bills in a waterproof envelope or fireproof safe.
• $200–$500 can go a long way in an emergency.

✅ 4. Light, Power, and Heat

• Battery-powered lanterns or headlamps are safer than candles.
• Have a solar or crank-powered emergency radio.
• Store backup power banks and solar chargers.
• Keep portable heat sources or thermal blankets.

✅ 5. Prep for Cooking

• Camp stove, BBQ grill, or fire pit.
• Store extra fuel or propane safely.

✅ 6. Prepare for Sanitation

• Extra toilet paper, trash bags, wet wipes, and hand sanitizer.
• 5-gallon bucket with a toilet lid for emergencies.

✅ 7. Medical Essentials

• Backup prescription meds and a solid first aid kit.
• Include allergy meds, bandages, ointments, and pain relief.

Mental Checklist: Ask Yourself Now

• Do I have 3 days of food and water?
• Can I heat or cool my home without power?
• Can I charge a phone or get news without internet?
• Can I cook?
• Can I pay if cards don’t work?
• What will I do if I can’t leave my house for 72 hours?

If the answer to any of these is “no” or “I don’t know”—you have a gap to fill.

Final Thought: Preparedness Is a Skill, Not a Panic

Too often, preparedness is framed as fear. But at Ready Master, we see it differently. It’s about being calm, capable, and in control when others are caught off guard.

Whether it’s the triple-digit heat of Arizona or a deep freeze in Colorado, the question isn’t if the power goes out—it’s when. And when it does, how ready will you be?

You don’t need a bunker. You don’t need to panic. You just need a plan—and the right tools.

Start small. Start now. Become a Ready Master.
