How to make your kitchen eco-friendly? It’s the heart of your home where friends and family congregate. But, it’s also where your energy consumption can be highest. To make your kitchen a whole lot greener, try these 18 sustainable kitchen ideas to save water and energy and reduce toxins in the environment.

1. Steam Vegetables Using Less Water

Use a steamer that sits over another cookpot containing food to steam your vegetables. Or, use a steamer insert in a pot with just enough water to steam the vegetables (tip: you don’t need to cover the vegetables. Just add an inch or less of water, but make sure lid is on, and avoid high heat.)

water in the kitchen can be conserved by steaming vegetables
Save precious water by steaming vegetables using only a small amount of water

This will lock in flavor and goodness, conserve precious water and energy costs.

Tip: Cool any excess water after cooking the vegetables and keep for use as stock or to water your plants as it holds plenty of nutrients.

2. Invest in Quality Eco-Friendly Cookware

When replacing or buying new cookware or kitchenware think of the possible production, use, or discard costs to the environment, e.g., in water or energy consumption or toxins released.

Some things to consider…

Is the product versatile? Being able to be taken from stovetop to oven, to the table for serving, and to the refrigerator for storage in the same pot for tomorrow’s reheating will save extra outlay.

Is it recyclable? What about the manufacturing process? Some brands, such as Xtrema, recycle the water used during manufacture.

Are there toxins potentially emitted from the product when heated or in production? Consider pots and pans that are free from toxins, e.g., PFTE and PFOA (I included the reasons to avoid these here).

If you prefer nonstick cookware, consider the ceramic coated type, which is PFTE and PFOA free.

Otherwise, check out my article on 100% ceramic cookware, for products made of material that is pure (no toxins), versatile, and should last you a lifetime with care.

Also good are stainless steel and cast iron cookware. I have an article on the benefits of cast iron skillets and review popular choices.

3. Use Lids on Saucepans When Boiling or Steaming

Using lids on pots to boil vegetables will save energy costs

Using lids on saucepans will prevent heat loss and save you energy costs. Once the liquid in the pan starts boiling turn the heat down to low. With the lid on it will simmer away nicely.

4. Use the Right Sized Pan for the Cooking Element

Having pots and pans cover the cooking element maximizes energy efficiency.

5. Clean Away Burnt Food

Keep cooktops in good working order to maximize energy efficiency.

6. Consider One-Pot Cooking

Stews or pot roasts require only one cooking element. Also, using a steamer that stacks on top of another pot will reduce the use of cooking elements.

Tip: Crockpots (AKA slow cookers) are ideal. 100% ceramic pots on the stovetop are also ideal.
The fewer pots and pans also mean less cleaning up!!

7. Cool Food Before Freezing

This will reduce the energy requirements of the freezer.

8. Fill Kettles and Electric Jugs Just Enough for Your Needs

When heating water, fill the container only to the level that equals the amount of water you need. This is smarter because it conserves energy usage in heating water you are not going to use. In countries with higher voltage, e.g. 230 v or above, such as in the UK, most of Europe, and Australia (compared to 120v in the US), it is wiser to boil water in an electric jug appliance. Because of the higher voltage, this is more efficient than using the stovetop.

9. Refrain From Opening Your Oven Door

When baking or roasting set a timer and avoid opening oven door as much as possible to prevent heat and energy loss. Ovens with clear view doors and internal lights help with this.

10. Refrain from Unnecessary Opening of Refrigerators and Freezers

This allows cold air to escape and results in extra energy being used to re-establish the temperature setting.

11. Keep Your Refrigerators/Freezers in Good Working Order

Here’s the deal…Defrost regularly. Although, modern models are usually self-defrosting and you may not have this issue. Nonetheless, frost should not be more than 6 mm deep.
Another smart move is to repair broken seals to reduce energy leakage.

Extra Tip: If a piece of paper placed between the door and the seal moves in and out easily, the seal isn’t working. Check whether the door might need adjusting or if not, replace seals.

12. Have a Drink Dispenser on the Bench

Fill it with iced water in summer. Add slices of lemon for refreshment.

A large container of cool water saves on energy loss with repeated refrigerator opening.
Everyone loves the easy access to refreshments during hot weather. Great with visitors or children.

Just the thing for entertaining.

Drink dispensers with a spigot for easy access are ideal.

13. Use Smaller Appliances

Here are some examples of how to do this, to save on energy costs…

In countries where voltage is high enough, use toasters instead of the stovetop or grill to toast bread and buns.

In slicing foods, use manual knives that are sharp (see my article on knives being the sharpest) and suited to the job, rather than an electric knife.

14. Turn Off Lights on Leaving the Room

Make turning off lights when not in use a habit.

15. Wait Until the Dishwasher is Full Before Running

It is more water efficient to run a full load than a number of smaller ones. Keep your dishwasher in good working order to save having to redo the load and also to conserve energy usage.
Clean the filter of the dishwasher regularly, is another tip.

16. Use Timers on Appliances

You will avoid overcooking and save on energy use.

Use timers to save burning your stuff and having to do it again! darn.

17. Use Manual Knives

Use manual knives that stay sharp for longer rather than electric knives where suited.

18. Compost Organic Waste

Have a compost for your kitchen scraps (fruit and vegetable scraps only). A small stainless steel compost bin to collect scraps is perfect for the kitchen bench. A top indoor compost bin includes a charcoal filter to reduce odors.

Final Thoughts

For some reason or other, our kitchens become a place of sharing wisdom and stories – sometimes over a cuppa or a glass of wine. Taking steps to reduce consumption, even small ones, and making them everyday habits can contribute overall to not only your budget but the wellbeing of the planet for tomorrow.
