19 Actionable Tips To Save Money And Live More Sustainably!

Living more sustainably doesn't mean spending more money. In fact, some of the most sustainable choices you can make are also the easiest ways to save money.

Simple habits like buying only what you need, wasting less food, using products for longer, and being more mindful of how much water, electricity, and other resources you consume can make a noticeable difference.

Fun Fact: The U.S. Environmental Protection Agency estimates that food waste costs each U.S. consumer about $728 per year. For a household of four, that's roughly $2,913 worth of food that isn't eaten.

The best part? You don't have to overhaul your entire lifestyle overnight. Whether you're trying to lower your monthly bills, reduce household waste, or simply live a little more sustainably, here are 19 actionable tips you can start today.

Save Money While Shopping

Actionable Tip #1: Keep a lightweight reusable tote bag in your car, purse, backpack, or near your front door so you actually remember to use it. It's a small habit, but it can help reduce your dependence on single-use shopping bags.

Actionable Tip #2: Plan your meals before grocery shopping to avoid buying food you don't need. When you buy with a plan, you're also less likely to end up with forgotten vegetables, duplicate ingredients, and expensive last-minute takeout.

Actionable Tip #3: Before buying something brand new, check a thrift store, resale website, or local reuse center first. You can often find clothing, furniture, kitchenware, books, tools, and other everyday items for much less than their original price.

Actionable Tip #4: Buying larger quantities can reduce packaging and sometimes lower the price per unit. However, bulk buying isn't automatically cheaper or more sustainable. If you buy more than you actually need, you've wasted both money and resources.

Actionable Tip #5: Instead of repeatedly purchasing bottled water, carry a reusable bottle and refill it with tap or filtered water when appropriate. Based on an average consumption of 167 bottles of water annually, switching from bottled water can save you a lot of money over time.

Actionable Tip #6: Share a ride whenever possible. Carpooling with just one other person to shopping or work can reduce your greenhouse gas footprint by around 2,000 pounds each year. Fewer cars on the road, less fuel consumption, and potentially lower transportation costs.

Save Money At Home

Actionable Tip #7: There is no reason to leave the water running while you're brushing your teeth. Depending on your faucet's flow rate and how long you leave it running, this simple habit can prevent up to more than 200 gallons a month if you brush twice a day.

Actionable Tip #8: If possible, try to cut a couple of minutes off your shower to save 4 to 6 gallons of water each time. The less time you spend under the shower, the less water you use, which can also help lower your utility bills.

Actionable Tip #9: When an old incandescent bulb burns out, replace it with an efficient LED rather than another incandescent. LED lighting can use up to 90% less energy than incandescent lighting and can last much longer.

Actionable Tip #10: Your home doesn't always need to be heated or cooled to the exact same temperature all day and night. The U.S. Department of Energy says adjusting a thermostat by about 7–10°F for eight hours a day while you're going to work can save as much as 10% per year on heating and cooling for applicable systems.

Actionable Tip #11: Unless you need hot water for a specific cleaning job, try using the cold cycle for your laundry because water heating accounts for about 90% of the energy used by a clothes washer. You can also save more by washing full loads instead of running the machine half empty.

Actionable Tip #12: Store your batteries at moderate temperatures, and avoid unnecessary full discharges and recharges to help your batteries last longer. Extending battery life means fewer replacements, which can also reduce the environmental impact associated with producing new batteries.

Save Money In The Kitchen

Actionable Tip #13: Don't run your dishwasher for a few plates simply because dishwashers generally use roughly the same amount of water and energy regardless of how full they are. It also recommends scraping food off dishes rather than pre-rinsing them under running water.

Actionable Tip #14: If possible, use your dishwasher instead of hand-washing. According to Flamingo Appliance, the average hand-washing session uses about 27 gallons of water, while the average dishwasher cycle uses between 4-6 gallons.

Actionable Tip #15: Freezing can help extend the useful life of many foods and prevent perfectly good meals from becoming spoiled. But consider starting a backyard compost pile or using a countertop system to turn food scraps into useful soil amendments.

Actionable Tip #16: Before throwing away a perfectly good glass jar, think about what else it could become. Wash and reuse jars for leftovers, dry foods, spices, small household items, craft supplies, or homemade sauces.

Actionable Tip #17: A damaged chair, scratched furniture, or malfunctioning appliance doesn't automatically mean “buy a new one.” You might discover that a $5 repair can save you from spending $50, $100, or much more on a replacement.

Actionable Tip #18: Instead of throwing away perfectly usable clothing, books, furniture, kitchen items, toys, or household goods, consider donating or selling them. This keeps products in use longer and can even put a little extra money back in your pocket if you sell them.

Actionable Tip #19: Choose products with less packaging when practical. Refusing extra bags, utensils, containers, or other disposable items can help keep your home free of frustrating trash while reducing the amount of waste that ends up in landfills and waterways.
