If you’re looking for practical ways to lower your monthly expenses, learning how to save on utility bills is a great place to start. Everyday habits — like doing the dishes or laundry — can quietly add up to big costs on your electric and water bills. Luckily, small changes in how you use your home appliances can make a real difference.
Simple adjustments in how you run your dishwasher, washer and dryer, or even your kitchen appliances can help you keep more money in your wallet and make your apartment more energy-efficient. Here’s how to make every load, cycle, and rinse count toward savings.
Save money while using the dishwasher
Your dishwasher can be an energy-efficient helper — or an energy drain — depending on how you use it.
Follow these updated tips on how to save on utility bills every time you press “start”:
- Run full loads, but don’t overload.
Dishwashers use about the same amount of water and electricity whether they’re half-full or packed properly. Wait until you have a full load, but don’t cram dishes too tightly or water won’t circulate effectively. - Skip the pre-rinse.
Most modern dishwashers are designed to handle lightly soiled dishes without pre-rinsing. Instead, simply scrape off large food pieces. Pre-rinsing can waste up to 20 gallons of water per load, so it’s an easy place to cut back. - Use the eco or energy-saver cycle.
Nearly all new dishwashers have an “eco,” “energy saver,” or “quick wash” mode that uses less water and heats it more efficiently. - Air-dry instead of heat-dry.
Turn off the heat-dry setting and prop the door open after the final rinse. Air drying uses zero additional energy — and your dishes will dry just fine in a few hours. - Adjust your water heater temperature.
If your dishwasher has a built-in water heater, you can safely lower your home’s water heater temperature to about 120°F. That’s hot enough for cleanliness but low enough to reduce heating costs.
How to save on utility bills when doing laundry
Laundry is another area where simple shifts in your habits can add up to noticeable savings — especially for renters who rely on shared laundry rooms or small in-unit machines. 
Here’s how to save on your utility bills and get cleaner clothes:
- Wash with cold water.
Modern detergents work perfectly in cold water, and switching from hot to cold for most loads can save you more than $100 a year on energy bills. Reserve warm or hot water only for heavily soiled items or bedding. - Run full loads.
Your washer uses almost the same amount of water and energy no matter the load size. If you do need to wash a small load, be sure to adjust the water level setting to match, if possible. - Clean the lint filter.
A clogged lint filter makes your dryer work harder, using more electricity. Cleaning it after every cycle improves efficiency and helps prevent fires. - Avoid over-drying.
Running the dryer longer than necessary wastes energy and can damage your clothes. Use your dryer’s automatic moisture sensor if it has one — it stops the cycle when clothes are dry. - Separate heavy and light fabrics.
Drying towels and jeans separately from lightweight items helps both loads finish faster. Mixing them forces the dryer to run longer than necessary. - Use the cool-down cycle.
Let the dryer’s final “cool-down” phase finish the job with residual heat. You’ll use less electricity without noticing any difference in results. - Keep the vent clear.
Make sure your dryer vent isn’t blocked or kinked. Proper airflow makes the machine run more efficiently and reduces the risk of overheating.
Learning how to save on utility bills doesn’t require major renovations or expensive upgrades, just mindful everyday habits. From air-drying dishes to washing clothes in cold water, each small change adds up over time.
By paying attention to how you use your dishwasher and laundry machines, and even your smaller appliances, you’ll not only see lower bills but also help conserve water and energy for a greener planet.
So, start with one habit today. Your wallet (and the environment) will thank you tomorrow.
