Reducing energy and water use at home isn’t just good for the environment, it’s also one of the smartest ways to cut down your monthly utility bills. From washing dishes to doing laundry, every small habit adds up.
In this guide, you’ll find 27 practical, affordable tips to help you conserve resources in your daily chores.
Whether you're a homeowner, renter, or first-time eco-friendly shopper, these strategies will show you how to save energy, reduce water waste, and support a more sustainable future, all while making your home more efficient.
Water and energy are more connected than you might think. Every time you use hot water, whether it’s for showers, laundry, or dishes, your home uses energy to heat it. That means cutting back on hot water helps lower both your water and energy bills.
Small changes like adjusting your water heater or installing low-flow fixtures can make a big impact on both fronts. By improving how you use heated water, you reduce your overall utility use in one of the easiest, most cost-effective ways possible.
Water heating accounts for roughly 18% of your home’s total energy use, according to the U.S. Department of Energy. That’s second only to heating and cooling. Every time you run hot water, you're paying for both the water itself and the energy to heat it.
Older heaters and frequent hot water use (like long showers or hot laundry cycles) drive those costs up even more. But small changes, like switching to cold washes or installing a low-flow showerhead, can cut your hot water use by thousands of gallons a year, saving both water and energy. It's a simple way to lower two bills at once.
Ready to make those changes? Let’s start with the quickest wins.
Want to start saving energy without overhauling your entire home? These quick fixes take 15 minutes or less and make a measurable impact on both your power usage and your utility bills. They’re perfect for renters, busy homeowners, or anyone looking for low-lift ways to live more sustainably.
From lighting swaps to smarter power use, these smart energy tips prove that going green doesn’t have to mean going all-in right away.
Lighting makes up about 10% of the average U.S. household’s electricity bill, and switching to LED bulbs is one of the fastest ways to cut that number down. LEDs use at least 75% less energy than incandescent bulbs and last 25 times longer, according to the U.S. Department of Energy. That means fewer replacements, less waste, and real savings over time.
For every incandescent bulb you replace, you can save around $50–$75 in energy costs over the bulb’s lifetime.
Want to take it a step further? Plug your devices into smart power strips. These strips detect when electronics (like TVs, computers, or coffee machines) are in standby mode and cut power to them automatically.
Phantom or "vampire" energy, the power used by electronics when they’re plugged in but not in use, can account for 5–10% of household electricity usage. With smart strips, you eliminate that waste without lifting a finger.
Quick Tip: Start with high-use areas like your kitchen, home office, and living room. Replace all overhead lights and plug clusters of devices into a single smart strip to simplify your setup.
Most water heaters are set to 140°F by default, but lowering the temperature to 120°F is a simple adjustment that can slash your energy bill without sacrificing comfort. Not only is 120°F plenty warm for showers, dishwashing, and laundry, but it's also the recommended setting by the DOE to prevent scalding and reduce energy usage at home.
According to the EPA, lowering your water heater temperature to 120°F can save up to 10% on water heating costs. For the average home, that translates to around $30–$60 per year, depending on your household size and hot water usage.
Adjusting your water heater is typically a quick DIY job. If you have a gas heater, you can usually turn the dial down manually. For electric models, you may need to remove a panel and adjust the thermostat settings with a screwdriver (always turn off power at the breaker first).
Bonus Benefit: Lower temperatures also slow down mineral buildup and corrosion in your heater, which can extend the life of your appliance and reduce maintenance costs.
Laundry might feel like a routine chore, but it’s one of the biggest opportunities for energy and water savings in your home. Between the electricity needed to heat water, the power your dryer consumes, and gallons of water used per load, making a few simple tweaks can have a major impact.
Whether you're tackling mountains of towels or small weekly loads, these energy-efficient laundry tips will help you wash smarter, not harder.
Here’s a surprising fact: about 90% of the energy used by a washing machine goes toward heating the water. That means one of the easiest ways to save energy at home is by switching your machine to the cold wash setting.
Most modern detergents, especially those labeled for cold water, are specially formulated to clean just as effectively without heat. Cold water is also gentler on fabrics, helping your clothes last longer and reducing microplastic shedding.
Savings Snapshot: According to Energy Star, switching from hot to cold water can cut your washing machine’s energy use by up to 50%, which could mean $50–$150 in annual savings, depending on your laundry habits.
Wondering how to reduce utility bills? Energy Star-certified washers and dryers will help you conserve energy and water while reducing expenses with every load. These water-saving appliances use 25% less energy and 33% less water than standard models.
Front-loading washers tend to be more efficient than top-loading ones and can fit larger loads, saving time and energy. Many Energy Star dryers now come with moisture sensors that automatically shut off the cycle once clothes are dry. That means you can save money on electricity.
Pro Tip: Check out rebate programs through your local utility or state energy office. Some Energy Star energy-efficient home appliances qualify for hundreds of dollars in rebates or tax incentives, especially under the Inflation Reduction Act.
Dryers are one of the most energy-hungry appliances in the home. But there are two simple ways to cut back on drying costs without skipping the fluff:
Your choice of laundry products matters just as much as your appliances. Traditional detergents often contain harsh chemicals and synthetic fragrances, which can pollute waterways and irritate sensitive skin.
That’s why we recommend switching to eco-friendly laundry detergent sheets and dryer sheets. These compact, plastic-free alternatives are just as effective as traditional products but without the waste. They’re biodegradable, plant-based, and designed to work in all water temperatures and machine types.
Bonus: Their compostable packaging and low-weight design also mean fewer emissions during shipping, helping shrink your laundry’s carbon footprint even more.
Dishwashing is one of those everyday chores where small habits can lead to big savings. When done thoughtfully, it’s a great opportunity for environmental benefits and saving money.
When it comes to the dishwasher vs. hand washing for energy use, contrary to popular belief, modern dishwashers are more efficient than hand washing.
According to the U.S. Department of Energy:
Factor in the energy used to heat that water, and dishwashers come out ahead, especially if you use eco modes and skip the heat-dry cycle. In fact, dishwashers can use 60% less water and 70% less energy than hand washing.
Sustainable Swap: Use HeySunday’s dishwasher sheets for a plastic-free, plant-powered clean. No dyes, harsh chemicals, or wasteful packaging—just one sheet per load, mess-free and cabinet-friendly.
One of the biggest dishwashing mistakes? Pre-rinsing dishes. It wastes water and confuses your dishwasher’s soil sensors, leading to weaker cycles.
Instead, try this:
When paired with HeySunday dishwasher sheets, you can save energy doing dishes. Your dishes will come out sparkling, without wasting water or using plastic-packed detergent pods. It’s a win for your wallet and a win for the planet.
The bathroom is one of the most water-intensive areas in your home, and much of that water is heated, making it an energy hotspot too. Thankfully, even small adjustments in your daily routine or affordable product upgrades can yield meaningful savings on both fronts.
These bathroom energy savers are easy to implement and don’t require a full remodel to make a difference.
One of the simplest, most cost-effective changes you can make is to install low-flow showerheads and faucet aerators.
These fixtures reduce the volume of water flowing through your taps without compromising pressure, allowing you to enjoy the same clean, invigorating shower experience with less water waste.
Here’s what to know:
These products are widely available at hardware stores or online, and many cost under $25. Most are DIY-friendly and can be installed in under 10 minutes with basic tools, making them a smart first upgrade for renters and homeowners alike.
Pro Tip: Check with your local utility provider. Many offer free water-saving kits or rebates for installing approved fixtures. Some even mail them directly to your door.
Hot showers feel great, but they come at a cost. Water heating accounts for about 18% of your home’s energy use, and long showers are one of the biggest culprits. Cutting just a few minutes off your routine can make a big difference.
Here’s how to get started:
Savings Snapshot:
And yes, shorter showers are still enjoyable—especially when paired with soothing lighting, natural body products, and maybe even a plant or two to green your bathroom space.
For long-term savings, pairing smart tech with small habit shifts is a winning combo. A few simple upgrades can make your home more efficient year-round.
Smart thermostats like the Google Nest or ecobee let you automate heating and cooling schedules. Set it lower when you’re out or asleep to save energy without thinking about it.
Wrapping your hot water pipes and tank with affordable insulation kits from a hardware store helps retain heat, so your system doesn’t work as hard.
Devices like Sense or Emporia show exactly where your energy is going. With real-time data, it’s easier to catch wasteful habits and make lasting changes.
