What Can I Do to Prevent Power Outages During a Heat Wave?

Here's how to keep cool even when the weather outside isn't.

Question: I live in Queens, New York, where the temperature recently got to a whopping 103 degrees in the summer! The weatherman on television said we see record-breaking temperatures like this once every 11 years. To boot, we lost power today for a few hours! Lucky for me, I had plenty of ice pops to keep cool, but I shudder to think about all the elderly people in my neighborhood without power. You got any tips on how to prevent power outages during extreme weather like this?

Answer: First of all, I can commiserate with you. It was 100 degrees where I live today, too. Lucky for me though, I didn’t lose power (not to gloat or anything). I did live in New York City for many a blazing summer—blech. I remember standing on the A-train platform, feeling like I was in a steam room that was on fire, aching for a freezing cold subway car to save me from the depths of hell, only to realize once I had gotten on the train that the air conditioning wasn’t working—double blech.

Usually, your energy service provider’s website will give you some good ways to reduce your energy consumption in such extreme weather. In my opinion, they should also be sending automated phone calls or e-mails to all their customers to remind them to reduce their energy consumption on days like today. (Correct me if you got a call; I know I didn’t.)

See, power outages occur in extreme heat when everyone on your grid is using too much power. It’s like everyone trying to pull on the highway at once — there just isn’t enough room for everyone! To prevent a power outage, you need everyone in your neighborhood to follow my advice (heck, everyone in the world should follow my advice), so do what you can to spread the word and forward this article to as many people as you can.

Here’s what I can recommend:

Turn off any household appliances that are not in use—toaster ovens, TVs, computers. And while you’re at it, unplug them since they still use electricity even when they’re off.

Also, turn off any lights you don’t need. Lights are a double whammy. Not only do they require energy to work, they also give off heat, making your AC work harder to cool things down. CFL bulbs produce 70 percent less heat than standard incandescent bulbs, so try to use these when you can’t leave your lights off altogether.

If you have central air conditioning, close off the vents in rooms you’re not cooling and close the doors to those rooms. This will concentrate air circulation in the rooms you’re using so your system won’t have to work so hard. If you have window units, turn off the ones you’re not using.

Also, use ceiling fans if you have them. They use less electricity than your air conditioner and let you raise the thermostat setting about 4 degrees with no reduction in comfort. I mean, think about it. Long before electricity, people were using fans to cool off (think Cleopatra’s banana leaf-waving servant). All you need is a battery-operated fan and a spray water bottle and you might as well be at the beach with an ocean breeze (instead of on the A platform).

Also for those with central AC, think about what temperature you need your house to be, not what temperature you’d like it to be. (I have a friend who keeps her house at a cool 68 degrees, just so she can sleep with her down comforter. I mean, it’s cozy, but come on.) The amount of energy needed to keep a house at 68 degrees when the temperature outside is over 100 is far greater than the amount of energy needed to keep it at, say, 78 degrees instead.

For more energy-savings tips, check out my article (and Matt’s article, too) on ways to beat the summer heat. And if all else fails, harken back to the days of yore and pretend you’re in a windowless cabin at summer camp! Only this time, you have money for snacks and a better hairstyle.

National Tell a Joke Day dates back to 1944 when President Franklin Delano Roosevelt was having a meeting with Vice-President, Henry Wallace. The two men were tired and depressed due to the stress caused by leading a country through world war.

During a lull in the meeting, Wallace said, "Frank, to cheer you up I have a joke I'd like to share."

"Let's have it, Henry," Roosevelt replied while ashing his cigarette.

"Why did the chicken cross the road?" Wallace asked. "Not sure," Roosevelt replied.

"To get to the other side," Wallace responded.

Roosevelt laughed so hard that the bourbon he was drinking sprayed out of his nose and onto the floor of the oval office.

The joke was so funny, and did such a great job at lightening both their moods, Roosevelt proclaimed that every year, August 16 would be National Tell a Joke Day.

Just kidding.

Nobody knows why National Tell a Joke Day started, but in a world where the President of the United States is trying to buy Greenland, "Beverly Hills, 90210" is back on TV, and the economy is about to go off a cliff, we could all use a bit of levity.

To celebrate National Tell a Joke Day, the people on Twitter responded with hundreds of the corniest dad jokes ever told. Here are some of the best.


The Judean date palm was once common in ancient Judea. The tree itself was a source of shelter, its fruit was ubiquitous in food, and its likeness was even engraved on money. But the plant became extinct around 500 A.D., and the prevalent palm was no more. But the plant is getting a second chance at life in the new millennium after researchers were able to resurrect ancient seeds.

Two thousand-year-old seeds were discovered inside a pottery jar during an archaeological excavation of Masada, a historic mountain fortress in southern Israel. It is believed the seeds were produced between 155 B.C. and 64 A.D. Those seeds sat inside a researcher's drawer in Tel Aviv for years, not doing anything.

Elaine Solowey, the Director of the Arava Institute for Environmental Studies at Kibbutz Ketura in Israel, wondered if she could revive the Judean Date Palm, so in 2005, she began to experiment. "I assumed the food in the seed would be no good after all that time. How could it be?" Solewey said.

There's been an uptick in fake emotional support animals (ESAs), which has led some airlines to crack down on which animals can and can't fly. Remember that emotional support peacock?

But some restrictions on ESAs don't fly with the Department of Transportation (DOT), leading them to crack down on the crack down.

Delta says that there has been an 84 percent increase in animal incidents since 2016, thanks in part to the increase of ESAs on airplanes. Last year, Delta airlines banned pit bulls and pit bull-related dog breeds after two airline staff were bitten by the breed while boarding a flight from Atlanta to Tokyo.

"We must err on the side of safety. Most recently, two Delta employees were bit by a pit bull traveling as a support animal last week. We struggled with the decision to expand the ban to service animals, knowing that some customers have legitimate needs, but we have determined that untrained, pit bull-type dogs posing as both service and support animals are a potential safety risk," Delta told People regarding the new rule.

Trying to get one dog to sit still and make eye contact with a camera for more than half a second is a low-key miracle. Lining up 16 dogs, on steps, and having them all stare at the camera simultaneously is the work of a God-like dog whisperer.

This miracle worker is Liam Beach, a 19-year-old animal management graduate from Cardiff, Wales. A friend of his dared him to attempt the shot and he accepted the challenge.

"My friend Catherine challenged me to try to get all of my lot sat on the stairs for a photo. She said, 'I bet you can't pull it off,' so I thought 'challenge accepted,'" he said, accoriding to Paws Planet.

Americans on both sides of the political aisle can agree on one thing: our infrastructure needs a huge upgrade. While politicians drag their feet on high-speed rail projects, fixing bridges, and building new airports, one amazing project is picking up steam.

The Great American Rail-Trail, a bike path that will connect Washington state to Washington, D.C., is over 50% complete.

The trail is being planned by the Rails-to-Trails Conservancy, a nonprofit that is working with local governments to make the dream a reality.
