If you’re looking for an energy efficient toaster, you might not need to look any farther than your own kitchen counter.
There are toasters that bill themselves as energy efficient, but the claims don’t really stand up to scrutiny, in my view. More on that below.
For most households, the amount of energy a toaster uses over the course of a year is pretty miniscule. It might not even be as much as the energy it takes to manufacturer a new toaster (and transport the old one to the landfill). For instance, a 900 watt toaster used for four slices a day for a year consumes only about 20 kilowatt hours of electricity per year. If you switched a 100 watt incandescent bulb for a 25 watt CFL, on a fixture used 2 hours per day, you’d save 55 kwh per year, or nearly three times what the toaster consumes. So serious energy savers can toast their bread with a clear conscience, and focus on other energy saving activities.
My advice to you in finding an energy efficient toaster is to look for a quality toaster with minimal bells and whistles. If you have bad toaster karma, as I do (two broken toasters in the last six months), you are better off looking for a very reliable toaster rather than the one that uses the least energy. Buying a new toaster every six months probably uses more energy (in manufacture of the new toaster, disposal of the old one, and transportation costs) than the toaster uses making toast over its useful life.
Find a simple, dependable toaster – preferably one with a longer warranty period, or one that gets consistently high customer reviews – and you’ll save more money and energy, in the long run, than by looking for the most energy efficient toaster you can find.
Some things to be careful about when shopping for a toaster:
- Extra long slots for home-baked or country-style bread can waste energy – the element is on for the entire length of the slot, even if the slices you are toasting are standard commercial loaf size.
- Four-slot toasters that don’t let you turn on only two slots at a time waste energy – if you need a four-slot toaster, look for one that lets you turn on only two slots at a time.
- Avoid toasters that come with LED indicators. LED lights use hardly any electricity at all, but if left on constantly, their usage does add up. For example, a 1-watt LED uses about 8 kwh if it’s on throughout an entire year – that’s almost half what a typical toaster uses to toast bread in a year!
Features of a hypothetical energy efficient toaster
If I were asked to design an energy efficient toaster, here are some features I would look for:
- Empty slot detection. A slot that has nothing in it shouldn’t go on.
- Individual slot control. If your toaster doesn’t have empty slot detection, it should at least let you manually disable one slot in a two-slot toaster if you’re only toasting one slice.
- Covered top. Hot air rises, so if the toaster could be made to cover its top while toasting, less heat would escape from the top, and so less electricity would be required for the same toasting power. I talk more about this below.
- Insulated sides. The sides of some toasters can get quite hot. An energy efficient toaster would be well insulated on the sides so that this heat stays where it’s wanted – where it toasts the bread – instead of escaping to the outside.
Does such a toaster exist? I haven’t found one. There are toasters that let you turn off unused slots, and toasters have varying degrees of insulation in them. Even the toaster I grew up with had words printed along the top: SINGLE SLICE IN THIS SLOT, although I don’t know how much energy that saved. And there is a toaster that covers the top while toasting to save energy, although I don’t buy that particular toaster’s claim to being energy efficient – I talk about that toaster at the bottom of the page.
Eggs and toast anyone?
How about this idea for saving energy while toasting: toast your English muffins, and poach your eggs, at the same time. Is this really an energy efficient toaster? Maybe not, but this item gets rave reviews from people who own it. If you’re into egg and english muffin breakfasts, it might actually save you energy because:
- It’s one appliance doing the work of two – no need to turn on the stove and boil a pan of water to poach only two eggs
- Easy clean-up – just the teflon egg poaching trays to wash out
- The toast and the eggs are ready at exactly the same time – and the eggs are done right. No need to cook a second set of eggs when you accidentally boil the first set to death!
I admit, I’m stretching things by billing this product as an energy efficient toaster. But I was struck by how many people love this toaster, and I really don’t believe looking for an energy efficient toaster is that important. As I already mentioned, toasters don’t really use much energy, and there are many things you can do in your home that will have a far bigger impact on your energy consumption and your electricity bill.
Ecolectric toaster from Morphy Richard
The Ecolectric toaster bills itself as an energy efficient toaster. It comes with an autoclose lid, which traps in heat while the bread is toasting. The manufacturers suggest that this saves up to 34% of the energy used to toast bread.
How much of a dent will this energy efficient toaster make on your annual electricity bill?
First of all, note that the toaster, if left plugged in, does have a phantom or vampire load, because of an LED light that stays on continuously (didn’t I mention that above in the list of features to avoid?). The load is likely negligible, however, since most LED indicator lights have a load of less than 1/20 of a watt.
Now let’s look at the toasting process. During toasting this toaster consumes about 1.1 kilowatts. That’s a little more than my 800 watt economy toaster, but the toasting should take less time because the autoclose lid on the toaster traps in heat. According to a review in REUK.co.uk, this toaster took 90 seconds to toast two slices of bread to ‘brown level 5’. That means 0.027 kWh for two slices of bread.
How does this toaster compare with my lowly economy model? I did two tests (with my toaster, since I don’t own this energy efficient toaster yet): I toasted two slices of bread the usual way; then I toasted another two slices, with a metal cookie tray on top.
|Mine, covered with cookie tray||800||76||16.9|
|Ecolectric energy efficient toaster||1100||90||26.5|
Note the measurements in the right column are in Watt-hours – in other words, if you toasted two slices of bread 1,000 times this way, that’s how many kilowatt hours it would use.
It looks like the Ecolectric scores lowest – but this is not a scientific comparison, as REUK did the tests with the energy efficient toaster using one kind of bread, and I used a different kind (probably much faster-toasting) in my experiments. But look at the savings I got with the covered test – 29% of the energy used in the uncovered toasting wasn’t used in the covered toasting, which means covering the toaster was 40% more efficient. So you can see that the Ecolectric energy efficient toaster is onto something with their covered top idea.
Let’s give this toaster the benefit of the doubt and support its manufacturer’s efficiency claims. Assuming it is 34% more efficient, we’ll say the 26.5 Wh it took REUK to toast two slices of bread would have taken 40 Wh on an equivalent toaster without a cover. Now let’s assume your family toasts six slices of bread a day, six days a week (pancakes on Sunday!). That works out to 25 kWh per year for the energy efficient toaster, compared to 38 kWh for its hypothetical inefficient cousin. So you’ll save 13 kWh a year in this scenario.
The sticker price is in the range of $50-60 US. So how does investing in an energy saving toaster compare with, for example, buying energy saving compact fluorescents or LED house lights? Let’s assume the lights in question are left on 2 hours a day every day, and are replacing a 100 watt incandescent light with an LED or CFL of the same light intensity.
|23 watt CFL||$1.88||26.67||1499.00|
|13 watt LED||$95.00||0.53||29.58|
The ‘Leverage’ column indicates how many of that unit you could buy with $50 US. As you can see, the Ecolectric toaster will save you 12.85 kWh a year (assuming you unplug it when not in use). A similar investment in LED house lights will save you 29.58 kWh a year, and the same money spent on CFLs would save you a whopping 1,499 kWh a year. So unless you have already converted all your incandescent and halogen light bulbs to energy saving light bulbs, this energy efficient toaster doesn’t sound like a high priority investment. And if you do leave the toaster plugged in all the time, that 12.85 kWh saved becomes only about 4 kWh. That’s a pretty small annual savings for a $50 investment.
The toaster is a full-feature energy efficient toaster, including the usual fancy features such as bagel toast and defrost. It also has a motorized carriage to lower the toast slices into the toaster. This to me is one of its big disadvantages. The beauty of the traditional toaster is that it has very few moving parts other than the push-down carriage, and very few controls; this is why some toasters made in the 50’s are still in operation today. A motorized carriage sounds like a breakdown waiting to happen – especially with all that heat being trapped inside the toaster to wear the motor down faster.
Disadvantages of the toaster include the fact that you can’t see your bread toasting; extra long slices of toast won’t fit in it (for example, the ones that come out of my tall-loaf breadmaker); and the fact that it is activated by an electronic button, which makes it easy to accidentally start the toaster running, if some other object on the counter bumps up against it.
Overall I would be wary of this energy efficient toaster unless you do an awful lot of toasting. Its two-year warranty is pretty short considering good-quality toasters should last 20+ years. If you really want an energy efficient toaster, you may just want to try covering your toaster with a cookie sheet. That certainly works for me!
Another so-called energy efficient toaster is the TRU Eco two slice energy toaster, available on Amazon. Again, the price is more than most would be willing to pay for a toaster – $70 – and it follows the same design principal as the Ecolectric, which as of 2014 appears not to be as widely available. It features:
- An automatically closing lid to keep the heat in
- An LED countdown timer – not sure why this is necessary
- Cool touch exterior – better insulation would improve efficiency slightly
This toaster appears to be a repackaging or redesign of the Ecolectric, and I suspect the benefits of buying it are mostly on the aesthetic or functional side; you will be hard pressed to earn back your $70 investment in energy savings.
Most indicator LEDs consume less than 0.05W. Where did you get 1W for your estimate of 8kWH for an LED left on constantly all year? That’s about 20x too high. Actual LED consumption is closer to 0.4kWH, and high efficiency LEDS can reduce that by another 10x.
There are many misconceptions about energy consumption. I think it’s important to correct gross errors like this so that people don’t begin telling each other that every LED consumes 8kWH per year until it becomes a “fact”.
The point is that people need to put their “energy” into saving energy in the right places. Replacing your incandescent or fluorescent home lights with LEDs will save vastly more power than choosing not to buy a toaster that has an LED indicator on it.
Thanks for pointing out this error. I wrote the article in 2008 and don’t recall where I got the LED wattage from, it is clearly wrong and I’ve corrected the statement. The power consumption for an LED indicator light is negligible. I once left an entire string of LED lights plugged into my Kilowatt Meter for a week to see how much energy they used. I believe the entire string of 50-odd bulbs was under 3 watts, so a single (and not as bright) toaster LED indicator would clearly not use this much. (On the other hand, my coffee maker really did use 2 watts when switched off but still plugged in – but I’ve since replaced it and the new one registers 0 watts on the KW meter.)
The power consumption for an LED is indeed negligible, but the power consumed by its voltage step down mechanism is not! You may need to re-check.
I don’t have one of these toasters with LED light to check, but every time I’ve measured a device that is plugged in but not operating, and has a single LED light, the power draw is too low to register anything at all on my Kill-A-Watt Meter. If anyone has one of these toasters and a Kill-A-Watt or equivalent, feel free to do a measurement and post it here.
Love this review and does show how trying to do the “right thing” by reducing what we can measure (cash/kwh) can do more harm through wastage/transportation etc. So, in short, don’t waste money replacing your toaster early just to save energy.
Sorry I’m a bit late to the party but….
I can add an even better improvement to efficiency of your existing toaster. If you are planning to use multiple cycles (i.e. 6 slices through a 2-slice toaster);
1st – always start the next cycle straight away. You’ll cut about 30% of the toasting time because everything is already hot.
2nd – use the next bread slices as covers whilst the current cycle is on. Not only does it trap in heat (speeding up current cycle) but it also part pre-toasts your next slices – reducing their time by a total of about 50%.
1. Covering the toaster whilst it’s on, when it’s not designed for that, could be dangerous. Never leave it unattended!!
2. Make sure you move and turn the covering slices to get an even pre-toast.
Thanks for the feedback and the additional tips.
The only caution I have on covering the toaster with anything, other than the danger factor, is that it may prevent humidity from escaping as the heat dries out the bread. This in turn could increase humidity levels on the heating element or other metal parts and eventually lead to corrosion. Probably not a problem in most climates but when I lived in humid Costa Rica for a year we went through three toasters, I imagine covering a toaster with the next slices in that environment would lead to even shorter toaster lives!
Thanks for doing this review,
The Ecolectric toaster is not energy friendly as it used energy in standby which makes it worse than other devices. Also the tray that auto loads is just another point of failure that will make it impossible to repair.
I would be interesting if you would do a test on some of these low watt caravan toasters.
I have the most basic toaster and it uses zero when not in use. It does not have a defrost button, just a dial and a lever to drop the toast. I bought it second hand for 50p back in 2011.
It seems to me that there is no effort by manufacturers of toasters to be energy efficient, all they do is make it shiny, put a copper colour or some flashing LED’s rather than looking at constructive ways to make it use less energy.
On a two slice toaster they do not need an empty slot sensor (it will just go wrong), they can just have a slider, slide to the back for 2 slice2 or to the front for 1, then it is just a circuit and cheap to produce.
I wonder if the ability to move the the toast closer to the heating elements with a slider might give some better options rather than just throwing more power at it with the dial.
I wonder if there is any energy to be saved by cooking it on max but ending cycle early, this would require watching but just interesting from a design point of view as it would tell us whether there is something a manufacturer could put into a design.
When we toast bread or other things we want them to go brown, I assume that the sensors that end the heating do so when there is a reflection of heat back from the toast, so putting a cookie tray on may make it shut off early, but the toast may not be at optimum.
Also I tried your idea of putting a cookie tray, well it was a small 9×6 inch baking tray, when the cycle ended the toast could not come up, the energy did not cut and the heating continued, I was not watching because my attention was on my coffee maker.
I turned to find the toaster on fire, now I need a new toaster and my kitchen cupboard above the toaster needs replacing!
I had no idea how hard it would be to put it out, I put a wet tea towel over it and it caught fire (power was off now), thank goodness I did not go to pee and forget I had put it on or I might need a new house.
So whilst a cookie tray could possibly save a bit of energy it might be better to buy a purpose built energy saving toaster, when one is actually made.
Unfortunately there is no advice about this, are we better off buying a 1200w or and 800w, if bread if frozen then heating at too high a temperature would probably leave toast brown on the outside but wet on the inside.
Sadly they do not make my trusted Tefal thick n thin toaster anymore, although it is ruined it still powers up.but stinks if I use it.
So for now, I will go buy a cheap toaster with good reviews, it is low tech which means I can repair it, it has a slide out tray for cleaning.
I appreciate your story and sorry to hear about the toaster fire.
I think the best way to look at toaster energy efficiency is to assess the maximum impact one might have by moving from the least to most efficient toaster. In the grand scheme of things, given what a small percentage of people are likely to care about toaster energy efficiency, it seems like one of the last problems we should be trying to solve.
A toaster might use 800-1500 watts. If you toast two slices of bread a day, and the toaster runs for 2 minutes, then you’re using 0.8-1.5 kWh/month of electricity on toast. In the worst-case scenario where 100% of your electricity comes from coal, that’s about 0.64 to 1.2 kg of CO2 equivalent emissions a month, or between 8 and 15 kg per year. The average per capita CO2 emissions in 2018, according to the World bank, was 4.48 metric TONNES. In other words, even if you found a toaster that used NO electricity, the net impact on your average CO2 emissions would be somewhere in the 0.2-0.3% range. At best, an energy efficient toaster will cut your energy use in half, so you’re in the 0.1-0.15% range if you eat toast EVERY day! We have MUCH bigger problems to solve than that. Let’s focus on things like eliminating all unnecessary air travel, switching our home heating systems to heat pumps or geothermal or passive solar, eliminating natural gas as an option for any new builds (e.g. by mandating electric / heat pump furnaces, water heaters etc.)
For people like me, who live off-grid, any appliance is immediately unplugged after use so we have no parasites sucking energy.
We have no toaster yet but I am getting annoyed with the old camping toaster that you lean your bread against the aides while cooking over a flame on a Coleman stove.
So any info on energy efficient toaster is great!.
