Earth Day Laundry: Small Changes That Actually Save Water and Energy

Laundry is one of those household chores that most of us do on autopilot. Toss in a load, crank the dial, move on. But it’s also one of the areas where small habit changes add up quickly — less water, less energy, less wear on your clothes, and a lower utility bill.

In honor of Earth Day, here are some changes worth making. None of them require buying anything special or overhauling your routine.

Wash in Cold Water

About 90% of the energy used by a washing machine goes toward heating the water. Switching from hot to cold water saves a significant amount of energy per load — and for most everyday clothing, cold water cleans just as well.

Modern detergents are formulated to work in cold water. The only times hot water genuinely matters: heavily soiled items, bedding if someone’s been sick, or items you need sanitized. For a regular load of clothes, cold works fine.

Run Full Loads

This one is straightforward. A half-full washer uses nearly the same amount of water and energy as a full one. Waiting until you have a full load before running it is one of the easiest ways to cut resource use in half — and it extends the life of your machine.

At a laundromat, this is even more obvious: loading a large-capacity machine to full capacity means fewer cycles total, less water overall, and more efficient use of everyone’s time.

Skip the Extra Dry Cycle

Over-drying is hard on fabrics and wastes energy. Modern dryers often have moisture sensors that stop the cycle when clothes are dry — use that setting instead of a timed cycle if you have the option.

Better yet: air dry what you can. Not everything needs the dryer. Hang shirts, jeans, and sweaters on a rack or a line on a dry day. In North Idaho’s spring and summer, there’s no shortage of good drying weather once the snow melts off.

Clean Your Lint Trap Every Single Time

A clogged lint trap makes your dryer work harder and run longer to dry the same load. Takes five seconds to clean. Do it every time. You’ll dry faster, use less energy, and reduce a genuine fire hazard.

Use the Right Amount of Detergent

More detergent does not mean cleaner clothes. It means residue left in the fabric, more rinsing required, and suds that can actually trap dirt. Check the recommended amount on your detergent and use that — or even a little less in a modern high-efficiency washer.

Concentrated detergents are also worth considering: smaller bottles, less packaging, same cleaning power.

Wash Clothes Less Often

A lot of clothing gets washed after one wear when it doesn’t need to be. Jeans, for instance, can typically be worn several times before washing. Sweaters worn over a base layer don’t need washing after every use. The care label is your guide — but in general, we over-wash.

Washing clothes less frequently saves water, extends fabric life, and reduces microfiber pollution in waterways — something worth thinking about if you’re near Lake Pend Oreille.

Choose Fragrance-Free Detergent

Synthetic fragrances in detergents often contain compounds that aren’t great for aquatic ecosystems. Since North Idaho’s waterways are worth protecting, it’s worth switching to fragrance-free or plant-based detergents when you can. They work just as well and are gentler on skin too.

Laundromats Are Often More Efficient Than Home Machines

This might be counterintuitive, but commercial laundromat machines are typically more water- and energy-efficient than older home washers. If your home machine is more than ten years old, doing a large load at a laundromat using a modern high-efficiency washer may actually use less water than running multiple smaller loads at home.

Small changes add up. Happy Earth Day from Ponderay Laundromat.
