Going Green: Should You Ditch the Dishwasher? A Water-Saving Showdown

 


Going Green: Should You Ditch the Dishwasher? A Water-Saving Showdown

(Because washing up shouldn’t feel like an environmental crime)

For years, the dishwasher has carried a reputation as an energy-guzzling luxury. But is handwashing really better for the planet? It turns out the answer is more complicated than “ditch the dishwasher.”

Let’s put the two methods head-to-head.

Round 1: Water Use

  • Dishwasher: A modern A-rated dishwasher uses about 9–12 litres per cycle.

  • Handwashing: A running tap can use up to 9 litres per minute. Unless you’re super disciplined with a washing-up bowl, you’ll almost certainly use more water by hand.

Winner: Dishwasher.

Round 2: Energy Use

  • Dishwasher: Most energy is used to heat the water. Eco-cycles and full loads are the key to efficiency.

  • Handwashing: Heating water in your boiler or kettle can be equally energy-hungry, especially for big loads.

Winner: Tie, depending on habits.

Round 3: Hygiene

  • Dishwasher: Hotter temperatures and longer cycles kill more bacteria.

  • Handwashing: Fine for lightly used items, but not as thorough.

Winner: Dishwasher.

Round 4: Convenience

  • Dishwasher: Stack, press, walk away.

  • Handwashing: Time-consuming and never-ending.

Winner: Dishwasher (and your sanity).

So, Should You Ditch It?

Not necessarily. The dishwasher isn’t the enemy if you:

  • Always run it full

  • Use the eco-cycle where possible

  • Skip the pre-rinse (modern machines don’t need it)

  • Air-dry instead of heat-dry

If you’re washing up one mug and a spoon, handwashing will win. But for a family dinner load, the dishwasher is likely greener.

Final Thought

The real showdown isn’t dishwasher vs sink — it’s efficiency vs waste. Use either method badly and you waste resources. Use them well, and both can be sustainable.

So don’t feel guilty about using your dishwasher. Just use it wisely.

Caffeine With a Conscience: Sustainable Coffee at Home

  Caffeine With a Conscience: Sustainable Coffee at Home ( How to keep your brew strong but your footprint light ) For many of us, coffee is less a drink and more a survival mechanism. But behind every comforting cup is an industry that comes with a hefty environmental and social cost. From deforestation to exploitative labour , the true price of coffee can be far higher than what you pay at the till. The good news? You don’t have to give it up. You just need to drink it smarter. The Hidden Cost of Coffee Coffee production is linked to deforestation, water waste , and pesticide use . Global demand encourages intensive farming that depletes soils and biodiversity . Billions of single-use cups and pods end up in landfill every year. Your morning pick-me-up doesn’t have to be part of the problem. Choose Better Beans Look for certifications that mean something: Fairtrade : Farmers get a fairer deal. Rainforest Alliance : Supports biodiversity and sustainab...

  Terracycling Explained: Because Some Plastics Just Won’t Die ( And yet somehow still end up in my cupboard ) We all know the recycling drill: bottles, cans, paper, cardboard. Simple enough. But then you’re left holding a crisp packet , a toothpaste tube , or that mysterious plastic wrapper that looks recyclable but definitely isn’t . Welcome to the world of Terracycle – where the plastics that haunt your kitchen finally get a second chance. 🧟 The Problem: Zombie Plastics Some plastics refuse to die.

  Shower Power – Saving Water Without Turning Into a Smelly Hippie ( Or: How Solar Hot Water Quietly Became the Unsung Hero of Sustainability ) Let’s talk about something personal. Steamy. Daily. Environmentally impactful. That’s right — your shower. Now, I’m all for reducing water use, but not if it means becoming one with your own scent . You’ll be glad to hear that saving water and energy doesn't require cold showers, fewer showers, or turning into a low-pressure dribble monk. Especially if — like us — you’ve tapped into the magic of the forgotten solar : solar hot water . 🌞 Why Solar Hot Water Deserves More Hype Everyone's talking about solar PV panels, battery storage, and smart meters. But solar thermal panels ? Hardly a whisper. Which is a shame, because: They’re cheaper to install They have fewer moving parts The return on investment (ROI) is often higher And they provide hot water for free from around March to October 🗨️ “Yes, our kettle i...
