Summer Energy-Saving Tips

May 6, 2025

Summer’s here—and while the sunshine is great, the spike in your energy bill? Not so much. Between blasting the AC and running more appliances, it’s easy to see why energy use shoots up this time of year. 

But the good news is you don’t need a total home overhaul to save money and stay cool. A few simple tweaks around the house can make a big difference in your comfort, your spending, and even your carbon footprint. 

Let’s dive into some easy, practical ways to keep your energy use in check this summer.

Adjust Your Thermostat Settings

One of the easiest ways to save energy in the summer is by tweaking your thermostat settings. Experts recommend keeping it between 76°F and 78°F when you’re home—cool enough to stay comfortable without making your AC work overtime. And if you’re away during the day, bumping the temp up a few degrees can lead to noticeable savings on your monthly bill.

If you haven’t already, now’s a great time to consider a programmable or smart thermostat. These little gadgets do the thinking for you, automatically adjusting the temperature based on your schedule. You can set it to cool things down right before you get home from work, or ease off at night when it’s naturally cooler outside.

With a smart thermostat, you can even control the temperature from your phone—whether you’re lounging at the beach or just too comfy on the couch. It’s a simple “set-it-and-forget-it” upgrade that can boost your home’s energy efficiency significantly. 

Maximize Natural Ventilation

On cooler mornings or in the evening when the sun starts to dip, open up your windows to let in the breeze. This can naturally bring down the temperature inside without using any electricity.

To really get that air moving, use ceiling fans or box fans strategically. Ceiling fans should spin counterclockwise in the summer to push cool air down, creating a gentle wind-chill effect that helps you feel cooler even if the thermostat is set a little higher. Place box fans near windows to pull in fresh air or push warm air out, depending on what your home needs.

Want to take it up a notch? Try cross-ventilation. Open windows on opposite sides of your home to create a pathway for air to flow through. It’s like giving your house a natural cooling system—and it’s totally free. With the right setup, you might be surprised how much cooler your home feels without touching the AC.

Block Out the Heat

When the sun’s beating down, your windows can turn into giant magnifying glasses, letting all that heat pour into your home. But with a few simple upgrades, you can block out a lot of that unwanted warmth and keep things much cooler inside.

Start by installing blackout curtains or thermal drapes—these are total game-changers. Not only do they help darken a room for better sleep, but they also act like insulation for your windows, trapping cool air in and keeping hot air out. They’re especially helpful in rooms that get direct sunlight during the day.

Blinds and window films are another easy win. Reflective window film helps bounce sunlight away before it heats up your space, while blinds let you control exactly how much light (and heat) gets in. Keep them closed during the hottest parts of the day to give your AC a break.

If you really want to go all-in, consider adding some exterior shading like awnings, shutters, or even pergolas over windows and patios. These block the sun before it even touches the glass, which means your home stays cooler naturally—and your energy bills stay lower. Plus, they can give your house a nice aesthetic upgrade.

Use Appliances Wisely

Believe it or not, your appliances can be sneaky sources of extra heat during the summer—especially the oven and stove. Cooking a big meal in the middle of the day can warm up your whole kitchen, making your AC work even harder to cool things back down. If you can, try to avoid using the oven during the hottest hours. Instead, grill outside, use a slow cooker, or make no-cook meals like salads and wraps.

When it comes to laundry and dishes, timing matters. Running your dishwasher or washing machine during the evening or early morning helps reduce the heat load on your home—and it can also save you money if your utility company offers off-peak energy rates.

And here’s a bonus tip: use cold water cycles when doing laundry. It’s easier on your clothes, better for your energy bill, and still gets the job done. If the weather’s nice, hang your clothes outside to dry. Little changes like these can really add up when it comes to staying cool and saving energy.

Seal and Insulate

If your home feels like it just can’t stay cool no matter how low you set the thermostat, you might be losing cold air through tiny gaps and cracks. Drafts around windows and doors are like open invitations for hot air to sneak in—and for your precious cool air to slip right out. Take a walk around your home and feel for drafts, especially near older windows and exterior doors. If you feel air movement, it’s time to seal things up.

One of the easiest ways to tackle this is with weatherstripping and caulk. Weatherstripping works great around doors and movable windows, while caulking is perfect for sealing up stationary gaps or cracks. These quick fixes help keep the inside air in and the outside air out—so your AC doesn’t have to work overtime.

And don’t forget about your attic. A poorly insulated attic can act like a giant heat sponge, letting all that summer heat filter down into your living space. Upgrading or adding insulation up there helps block that heat, keeping your home cooler and more comfortable without cranking up the AC. It’s one of those behind-the-scenes improvements that makes a huge difference over time.

Upgrade to Energy-Efficient Devices

If your appliances and electronics are a bit outdated, they might be using way more energy than necessary—especially during the summer when everything’s working a little harder. Upgrading to energy-efficient devices is one of the smartest moves you can make to save on your utility bills and keep your home running smoothly.

Start with the big stuff. If your air conditioner, fridge, or washer and dryer are due for an upgrade, look for ENERGY STAR® certified models. These are designed to use less energy without sacrificing performance, which means you’ll stay comfortable while cutting down your energy use—and saving money in the long run.

Even small swaps can make a difference. If you’re still using old-school incandescent bulbs, switching to LED light bulbs is a no-brainer. They use a fraction of the energy, last way longer, and don’t give off nearly as much heat.

Consider Renewable Energy Options

If you’ve ever looked at your summer energy bill and thought, there’s gotta be a better way, renewable energy might be your answer. Going green isn’t just good for the planet—it can also help you save big on electricity, especially during those scorching summer months.

Solar panels are probably the most well-known option, and for good reason. They soak up all that sunshine and turn it into usable energy for your home, which can dramatically cut your electric bill—sometimes even eliminating it altogether. Plus, during peak AC season when your energy use is highest, your panels are also working their hardest. 

But panels aren’t your only option. Solar water heaters use the sun’s energy to warm up your water, taking the pressure off your electric or gas-powered system. And solar attic fans? They help push hot air out of your attic, making your home cooler overall and lightening the load on your AC.

Don’t forget to check for local rebates and incentives, too. A lot of states, cities, and utility companies offer financial perks for installing solar or other renewable energy systems, which can make the upfront cost way more manageable. It’s definitely worth doing a little research—you might be surprised how affordable going solar can be.

Outdoor Energy Tips

Your outdoor setup can actually play a big role in how much energy your home uses during the summer—so why not let your backyard do some of the work?

For starters, swap out those plug-in pathway lights or porch lights for solar-powered options. They charge up during the day and automatically glow at night, all without adding a single cent to your energy bill. It’s an easy way to make your yard look great and save energy at the same time.

Another smart summer move? Take your cooking outside. Grilling on the patio instead of using the oven or stove helps keep the heat out of your house. 

And while you’re out there, take a look at your HVAC unit. Keeping it clean and shaded can actually improve its performance. Trim back any overgrown plants around it, make sure the vents aren’t blocked, and rinse off any dust or debris. 

Final Thoughts

When the temperatures rise, so can your energy bills—but they don’t have to. With just a few simple changes around your home, you can stay cool, save money, and use less energy all summer long. From adjusting your thermostat to grilling outside and swapping in energy-efficient appliances, these small tweaks really add up.

The best part? Most of these tips are super easy to do and won’t require a big investment of time or money. Whether you tackle one project at a time or knock them all out in a weekend, you’ll be setting yourself up for a more comfortable and cost-effective summer.
