Not to brag, but I’m usually pretty good at guessing what my bills are going to be every month; the only exception is when it comes to electricity. Depending on whether or not I dared turn the air conditioner on, it can range from $80 all the way up to $300. And if I’m being honest, a surprise $300 deduction from my bank account is not something I ever look forward to. That’s why I’ve put together this list of genius, cheap things that can help save you tons of money on your electricity bill.

From cooling neck fans to energy-efficient light bulbs, you’ll find no shortage of smart ways to help lower your bills on this list. Hot sleepers can appreciate the cooling bed sheets I found, while coffee lovers will enjoy the manual grinder I’ve made sure to include. Or, if you’re tired of walking around in the dark at night, I’ve also featured a variety of motion-sensor lights that’ll only turn on when you’re present — and that’s just the start. If you want to see more? You’ll just have to keep scrolling.

If you tend to run hot while sleeping, try swapping out your pillowcases with these cooling ones. They’re made from 100% soft, breathable bamboo viscose that allows for maximum airflow, helping keep you cool at night. Plus, they even come in nine colors to match your current sheets.

Not only is this knee pillow great for side sleepers, but it’s also filled with cooling gel that helps dissipate your body heat while you’re in bed. The breathable cover is also removable for easy washing — just in case you do get a little sweaty — and the inside is filled with soft, comfortable memory foam.

Utilizing your dishwasher could use up electricity, so why not save some money by using this dish rack? It’s made from sturdy bamboo and has enough space for up to 14 dishes. Plus, you can even collapse it down to a fraction of its size when putting it into storage.

Unlike some light bars, these ones are made with built-in motion sensors that prevent them from turning on when no one is around. The result? A possible dip in your utility bill — and since they’re powered by rechargeable batteries, there’s no complicated wiring required during installation.

Instead of utilizing your electric coffee maker, why not try this pour-over option? The stainless steel filter should never have to be replaced, eliminating the need to buy disposable paper filters — and the pitcher is even made from heat-resistant borosilicate glass. There are even measurement notes on the side, along with a nonslip bottom.

Since this coffee grinder doesn’t use any electricity, you can easily use it when camping — or even if you’re simply trying to cut back on your utility bill. The gears are made from rust-resistant stainless steel that’s less likely to dull over time. Plus, its compact size takes up little space in cabinets or backpacks.

There’s no need to crank the air conditioning when you’re snuggled up tight in these bed sheets. Not only are they breathable, but they’re also moisture-resistant — just in case you do happen to get a little warm. And since they have an extra-deep pocket, it’s less likely that the fitted sheet will ride up onto your mattress overnight.

Adding lights to your home doesn’t have to be complicated: These LED puck lights use three AA batteries each to provide multiple hours of light, which means wiring isn’t required to get them up and running.

Speaking of easy-to-install lighting, simply press each of these garden lights down into the ground and they’ll be ready to go.

It’s almost too easy to lose snacks in the back of a disorganized fridge, causing you to keep the door open for longer than needed — so why not tidy things up with these bins?

Pair this smart thermostat with Alexa, and you’ll be able to turn the air conditioner up using your smartphone so that you walk into a comfortably cool home.

Even the wettest, soggiest pair of jeans won’t bring this drying rack down, as its tough steel frame can easily support up to 32 pounds. It’s also powder-coated to help prevent stains and rust, and it can collapse down to a fraction of its size for easy storage. Choose from two finishes: white or chrome.

Whereas incandescent bulbs will burn out after a few months, these smart bulbs have a lifespan of up to 20,000 hours, making it highly unlikely that you’ll have to change them out anytime soon. You can also adjust their color and brightness, as well as put them on schedules so that they’re on when you come home — all using the free downloadable smartphone app.

Leaving the freezer open isn’t just a waste of electricity, as all that food can spoil if you aren’t quick to close it.

If your windows could use a little extra weatherproofing, consider this tape an affordable alternative to hiring professionals. The adhesion is moisture-resistant, helping to keep it in place no matter how rainy the weather gets.

Not only is this smart surge protector compatible with Alexa and Google Home, but it also features two USB ports (as well as three outlets) so that you can easily charge your phone whenever you need to — no extra power brick required. And if you aren’t home and need to turn the lights off, simply use the free Kasa app to turn them off remotely using your smartphone.

With thousands of positive four- and five-star reviews, it’s clear that these curtain tiebacks are a hit with Amazon shoppers.

Thanks to these, you’ll be able to easily let natural light inside.

Sometimes, cooking meals in the oven requires a lot of electricity — so why not save yourself some money and use this air fryer instead?

Plus, the frying basket is even safe to run through the dishwasher when disconnected.

Air conditioning bills are no joke, making this personal fan a must-have if you’re trying to save money.

Don’t forget to bring one of these cooling towels with you the next time you’re headed out into the sun for a heated workout — or even just a fun day at the beach.

If the doors in your home could be insulated a little better, why not try out this draft stopper?

Thousands of reviewers were blown away by how well it works — and one even wrote, “It'll pay for itself with the heater/AC kicking on less often.”

Microfiber can absorb more water than cotton, which means using this hair towel can save you some time underneath a hair dryer, resulting in a lower utility bill — especially if you dry your hair every day.
