Energy-efficient cooking methods and appliance usage
Let’s be honest. When you’re trying to save money and be a bit kinder to the planet, the kitchen probably isn’t the first place you think of. But it should be. It’s the heart of the home, sure, but it’s also a real energy hog. All that heating, boiling, and baking adds up on your utility bill.
The good news? You don’t need a kitchen full of brand-new, super-expensive gadgets to make a difference. Honestly, some of the most effective energy-efficient cooking methods are about changing your habits, not your hardware. It’s about working smarter, not harder. And who doesn’t want that?
Your kitchen’s secret energy savers: the simple habit shifts
Before we even talk about appliances, let’s talk about technique. These are the no-cost, high-impact changes that can slash your energy use starting tonight.
1. The lid is not optional
This is maybe the easiest win in the whole kitchen. Boiling water or simmering a sauce with the lid off is like heating your entire house with the windows open. You’re just letting all that precious heat—and the energy that created it—escape into the room. Putting a lid on a pan traps the heat, bringing water to a boil much faster and allowing you to cook at a lower temperature. It’s a simple move that can reduce energy use for that task by up to two-thirds. Just think about that.
2. Match your pan to the burner
Here’s a common sight: a small pot sitting on a giant electric coil. All that heat is spilling around the sides, wasting energy and potentially damaging your cookware handle. Using a pan that’s roughly the same size as the burner element ensures the heat goes directly into your food. On a flat-top electric or induction cooktop, a flat-bottomed pan is absolutely essential for good contact and efficient heat transfer.
3. Embrace residual heat
Your oven and stovetop don’t cool down instantly. They hold onto heat for a surprisingly long time. You can use this to your advantage. For the stovetop, turn off the burner a minute or two before your food is completely finished cooking—especially for things like pasta or steamed vegetables. The residual heat will carry it over the finish line.
And the oven? Well, if you’ve just baked a roast or a casserole, turn it off a few minutes early and leave the door shut. That lingering heat will finish the job. You can even use the warm oven to proof bread dough or warm up plates. It’s free heat!
A guide to energy-efficient appliance usage
Okay, now let’s get into the tools of the trade. How you use your appliances matters just as much as which ones you choose to use.
The microwave: your efficiency champion
I know, it doesn’t feel as “chefy” as the stove. But for many tasks, the microwave is a powerhouse of efficiency. It heats food directly by agitating water molecules, rather than heating the air around it (like an oven) or a metal pot (like a stove). This direct action makes it incredibly fast and effective for:
- Reheating leftovers: It’s faster and uses up to 80% less energy than a conventional oven.
- Steaming vegetables: A splash of water in a covered dish steams veggies perfectly in minutes.
- Melting butter or chocolate: No need for a double boiler; just use short bursts of power.
- Cooking smaller portions: Why heat a giant oven for one baked potato?
The slow cooker: low and slow saves energy
Don’t underestimate the humble slow cooker. It uses about as much energy as a standard light bulb. By cooking food over a long period at a low temperature, it tenderizes cheaper cuts of meat and develops deep flavors, all while sipping electricity. It’s a fantastic set-it-and-forget-it option for busy days that keeps you from relying on more energy-intensive appliances.
The toaster oven: the mini-marvel
Need to toast, bake, or broil a small-to-medium amount of food? The toaster oven is your best friend. It can use one-third to one-half the energy of a full-sized oven because it has a much smaller space to heat. Think garlic bread, a small frozen pizza, or roasting a single chicken breast. Preheating happens in a flash, too.
The pressure cooker (Instant Pot): speed is efficiency
Pressure cookers, including the popular multi-cookers, are brilliant for energy-saving cooking techniques. By creating a sealed, high-pressure environment, they raise the boiling point of water, which cooks food dramatically faster. A pot of beans that normally simmers for hours can be done in under an hour. Faster cooking time directly translates to less energy consumed.
Mastering your oven and stove
These are the big players, and with a few tweaks, you can make them much more efficient.
Oven smarts
Preheat wisely: Only preheat when necessary. For roasts or casseroles that cook for a long time, preheating is often optional—just add a few minutes to the cook time. For baking, yes, you need it.
Skip the peeking: Every time you open the oven door, the temperature can drop by 25 degrees Fahrenheit or more. The oven then has to work hard to get back up to temp. Use the light and the window instead.
Batch cooking: If the oven is on, make the most of it! Bake a tray of potatoes for later in the week while you’re roasting a chicken. Cook two casseroles instead of one and freeze the extra.
Stovetop savvy
Choose your weapon: If you have an induction cooktop, you’re already using the most efficient type of stovetop—it heats the pan directly through magnetic fields with almost no wasted heat. But for others, here’s a quick comparison:
| Cooktop Type | Approx. Efficiency | Key Tip |
| Induction | 85-90% | Requires magnetic cookware. |
| Gas | 40-55% | Keep burners clean for a blue, efficient flame. |
| Electric Coil | 70-75% | Match pan size to coil for best results. |
| Ceramic Glass | 75-80% | Turn off early to use residual heat. |
Keep it clean: On a gas stove, a clean burner with clear ports ensures a clean, hot, blue flame instead of a lazy, sooty yellow one. On electric stoves, spilled food on the coils or glass top can block heat transfer.
Beyond cooking: the supporting cast
Efficiency isn’t just about the act of cooking. It’s about everything that supports it.
Your refrigerator and freezer
These are the only appliances that run 24/7, so their efficiency is critical.
- Defrost regularly: A thick layer of ice acts as an insulator, forcing the motor to work harder.
- Check the seals: Close the door on a dollar bill. If you can pull it out easily, the seal needs replacing. Cold air leaking out is money leaking out.
- Let food cool: Don’t put hot food directly into the fridge. It forces the appliance to work overtime to cool down. Let it come to room temperature first (within safe time limits, of course).
The humble kettle
Boiling water for pasta? Use an electric kettle. It’s generally more efficient than a stovetop. But here’s the pro tip: only boil the amount you actually need. No sense in heating a full kettle for one cup of tea.
Small steps, big impact
You know, becoming an energy-efficient cook isn’t about a complete overhaul. It’s a mindset. It’s about noticing the little things—the lid left off, the oversized burner, the half-empty oven. Each small adjustment might seem insignificant, but together they create a ripple effect.
You’ll see the difference on your energy bill, sure. But you might also find a new rhythm in the kitchen—a slower, more intentional approach that feels less frantic and more… well, nourishing. It turns out that saving energy can also mean savoring the process. And that’s a win for your wallet, the planet, and maybe even your peace of mind.
