“What gets measured gets managed.” – Peter Drucker
When you finally look at where your electricity bill is going, the laundry room is often a surprise. One small metal box – your Washing machine energy saving – can quietly chew through a huge chunk of your household energy, especially if you love doing lots of little loads or always hit the “hot” button.
The good news? You don’t need a new house or a fancy solar setup to make a difference. A few small shifts – cooler water, smarter load sizes, better cycle choices – can dramatically shrink the energy (and money) your laundry uses, without leaving your clothes dingy or still smelling like the gym.
As environmentalist Annie Leonard famously said, “There is no such thing as ‘away.’ When we throw anything away it must go somewhere.” That’s true of energy too: every unnecessary kilowatt-hour burned in your laundry room means more fuel burned somewhere else. Learning how to use your washer more efficiently is one of the simplest ways to cut your carbon footprint while also treating yourself to a lower utility bill.
In this guide, we’ll walk through how washing machines really use energy, what temperatures actually clean your clothes, how to size your loads properly, and which settings are worth using. By the end, you’ll know exactly how to get clean laundry with the smallest possible hit to your wallet – and the planet.
The Hidden Cost of Laundry: Understanding Washing Machine Energy Consumption
When you do laundry every day, you might not think about how much energy it uses. Your washing machine is a big user of energy. It uses a lot of power to heat water and run its parts.
How Washing Machines Use Energy
Washing machines use energy for two main things: heating water and running the motor. Heating water uses the most energy. It takes a lot of electricity to warm up the water.
Heating Water: The Biggest Energy Draw
Heating water is about 90% of the energy used in a wash cycle. You can save energy by washing in cold water. Modern detergents work well in cold water.
Motor Operation and Mechanical Energy
The motor is another big energy user. It powers the wash and spin cycles. Making the motor more efficient can save a lot of energy.
The Environmental Impact of Inefficient Laundry Practices
Inefficient laundry practices raise your utility bills and harm the environment. The carbon footprint of your washing machine depends on how much energy it uses.
Carbon Footprint of Regular Washing

Conclusion
If you zoom out, most of the big wins in your article fall into four simple habits:
- Wash colder.
For most everyday loads, cold water works just as well as warm or hot when paired with modern detergents – and it avoids the biggest energy draw in your washer: heating the water. The Department of Energy’s Energy.gov+1 - Wash fuller.
A machine that is sensibly full (not jam-packed, not half-empty) uses the water and energy of one cycle to clean more clothes, dramatically cutting the energy per T-shirt or towel. - Let the machine help you.
Eco modes, automatic load sensing, and high-speed spin cycles are there to reduce water use and shorten drying time. ENERGY STAR washers can save about 25% more energy and 33% more water over their lifetime compared with basic models. ENERGY STAR - Finish with low-energy drying.
Line-drying when you can, or at least spinning on a higher RPM and using lower dryer heat, often saves more energy than any single washer tweak. Dryers typically use even more energy than washers per cycle. vileda.co.uk+1
None of that requires you to be perfect. It just asks you to be a little more intentional: wait until you have a proper load, hit “cold” instead of “hot” by default, use eco cycles when they fit, and hang a few more things to dry. Over a year, those tiny decisions add up – to fewer kilowatt-hours burned, lower bills, and a smaller carbon footprint.
Laundry will never stop being a chore. But once you’ve dialled in an energy-smart routine, it becomes one of the easiest places in your home to quietly save money every single week, while doing something genuinely kind for the planet.
FAQs
Q1. What is the most energy-efficient way to do laundry?
The biggest wins are simple:
- Wash most loads in cold water
- Run full, but not overstuffed loads
- Use the machine’s eco / energy-saving cycle when you can
- Choose an ENERGY STAR–rated washer when you upgrade
- Dry on a line or rack when possible, or use a high-spin / low-heat dryer combo
The U.S. Department of Energy notes that heating water is usually the largest energy cost in a wash, so switching to cold for most loads is huge. The Department of Energy’s Energy.gov+1
Q2. Does washing clothes in cold water really save energy?
Yes, big time. For a typical machine, up to 80–90% of the energy used in a wash cycle can go into heating the water. The Department of Energy’s Energy.gov+1 Switch that dial to cold and you remove almost all of that heating load. Modern detergents are designed to work in cold, and cold water is actually better for colorfastness and preventing shrinkage. The only time hot makes sense is for very greasy items, cloth nappies, or when you specifically need a sanitizing hot cycle.
Q3. Is it cheaper to do laundry at night?
It can be, depending on your electricity tariff. If your utility uses time-of-use rates, power is more expensive during peak hours (usually late afternoon / early evening) and cheaper during off-peak periods (overnight or mid-day). In that case, running your washer and dryer in off-peak windows can definitely lower your bill. Check your bill or your utility’s website for “time-of-use” or “peak pricing” details.
Q4. Do full loads really save money compared to several small loads?
Yes. Your washer and dryer use almost the same amount of electricity to run a cycle whether the drum is half-full or sensibly full. So:
- 1 full load = 1 cycle of energy
- 2 half loads = 2 cycles of energy
As long as you’re not over-stuffing the drum so clothes can’t move, waiting until you have a proper load is almost always cheaper and more efficient per item. laundrylife.co.uk+1
Q5. Which uses more electricity: the washer or the dryer?
In most homes, the dryer is the bigger energy hog. The washer uses some energy (especially if you’re heating water), but the dryer has to move a lot of hot air and spin a heavy drum for a long time. That’s why things like a high spin speed in the washer, line drying, or partially air-drying before a short tumble can cut your overall laundry energy use dramatically. vileda.co.uk+1
Q6. How often should I wash clothes if I want to save energy?
You don’t need to wash everything after one wear. Jeans, sweaters, pyjamas, and jackets can often go multiple wears if they’re not sweaty or visibly dirty. The less you wash:
- The fewer loads you run
- The more full each load can be
- The longer your clothes will last
That doesn’t mean walking around in dirty clothes – just using a bit of judgment instead of throwing everything straight in the basket after a few hours.
Q7. Is it worth paying extra for an ENERGY STAR washing machine?
If you do regular laundry, usually yes. ENERGY STAR–certified washers generally use about 25% less energy and 33% less water than standard models, and they often have better spin performance (which saves dryer energy too). ENERGY STAR+1 Over the lifespan of the machine, that can easily save hundreds of dollars – plus a lot of water and CO₂.
5. Real human feedback
You asked specifically for real human feedback:
“We switched to doing almost everything on cold unless it’s towels/sheets or truly gross stuff. Between that and only running full loads my power bill dropped more than I expected tbh.” Reddit
“Line drying was the sleeper hit for us. I still use the dryer for socks/underwear but hanging shirts and jeans cut a noticeable chunk off the bill and they actually look better too (less shrinkage, less lint).” Reddit
