Welcome to the second post in my most energy efficient appliances series – the energy efficient dishwasher.
It’s been over two years since I published the first post in the series – 5 of the Most Energy Efficient Refrigerators, but guess what? It is still the most visited post on Of Houses and Trees.
This is great news! Because it means that people are regularly searching for ways to make their homes more eco-conscious. Or maybe they’re just looking for ways to save on their electricity bills…
Whatever the reason is – I’ll take it!
But let’s not stop at energy conscious fridges. Next up in my most efficient appliances series – the energy efficient dishwasher.

How Much Electricity Does a Dishwasher Use?
So, what makes an eco friendly dishwasher, well, eco friendly? Much like refrigerators, the amount of electricity it consumes is a key factor.
As with my post on energy efficient fridges, I’ll be recommending Energy Star dishwashers in this post. According to the Energy Star website, a standard-sized dishwasher must consume less than 270 kwH of energy per year.
How Many Gallons of Water Does a Dishwasher Use?
Dishwashers also have the additional component of water consumption. And in order for a dishwasher to truly be gentler on the planet, it also has to use less water than traditional models.
Energy Star rated water efficient dishwashers must consume no more than 3.5 gallons of water per cycle.
5 of the Most Energy Efficient Dishwashers
Here are five energy efficient dishwashers listed on the Energy Star website. Note that Energy Star has a Most Efficient Dishwashers list – where they list the best of the best.
However, this list is dominated by Miele, which is a pricier brand and is usually found at specialty kitchen stores, rather than home building stores like Home Depot.
Instead of focusing only on the most efficient list, I also selected Energy Star models from easier to find brands with more accessible price points.
One last note, you can buy dishwashers with a plastic tub inside – and they are typically more affordable – but I’ve only listed dishwashers with stainless steel tubs as I feel they are more sustainable overall.
Energy Star Dishwasher: Frigidaire 18″ Built-In Dishwasher FFBD1831UB (270 kwH/year)
Type: 18″ Built-In Dishwasher (still considered standard capacity even though it’s slimmer)
Model Number: FFBD1831UB
Estimated Energy Use: 270 kwH/year
Estimated Water Use: 3.5 gallons/cycle
Tub Material: Stainless Steel
I hope this post helps you find the eco friendly dishwasher of your dreams. Make sure to check out my energy efficient refrigerators post if your dishwasher needs a friend!
