If you're in the market for new appliances, whether for a kitchen upgrade or replacing a worn-out unit, opting for energy-efficient options is wise. These appliances not only lower your energy bills but also contribute positively to the environment.

But how do you begin shopping sustainably for these appliances? This concise guide provides the key insights you need.

Selecting Energy-Efficient Appliances

The U.S. Department of Energy (DOE) emphasizes the importance of purchasing energy-efficient appliances to minimize emissions and generate long-term savings on utility bills.

When considering appliances, keep in mind two cost factors: the upfront purchase price and the ongoing operational costs over the appliance's lifespan. You'll pay for the operational cost every month on your utility bill for a decade or two, depending on the appliance. For reference, refrigerators typically last around 12 years, washing machines about 11 years, and air conditioners roughly nine years.

Look for features and labels that indicate lower operating costs when shopping.

Here's what you should know:

1. Examine Labels

Energy Star labels are a great way to identify top-performing energy-efficient products. These labels also appear on windows, water heaters, and other electronics. EnergyGuide labels, distinguishable by their yellow and black design, indicate an appliance's average yearly energy usage and operating costs, allowing for easy comparisons.

In the UK, appliances such as dishwashers, fridges, and freezers are rated from A (high efficiency) to G (low efficiency) since 2021, while ovens and microwaves range from A+++ to D. 

'The efficiency rating reflects the energy consumption of the appliance compared to similar models,' notes a representative from the UK's Energy Saving Trust.

2. Opt for Appropriately Sized Appliances

Choosing the right size for your appliances is crucial. For instance, running a large washing machine or dishwasher half-full is less efficient than using a smaller model designed to be filled. A fully loaded refrigerator also operates more efficiently than one that is frequently empty.

'Appliances are rated by size, meaning a large and a small fridge can share the same energy rating, but the larger unit might consume more power. Always seek the best energy rating for the size you need,' advises the same representative.

Conversely, air conditioning units that are too small for your space will run longer and harder, leading to inefficiency.

3. Use Appliances in Eco-Friendly Ways

Utilizing eco settings, such as those found on dishwashers, can enhance energy efficiency. Similarly, washing clothes at lower temperatures saves energy. Replacing a tumble dryer with a dehumidifier can also be more energy-efficient, as can opting for a refrigerator with a top or bottom freezer rather than a side-by-side model.

4. Consider Smart Appliances

Smart appliances can be significantly more efficient compared to traditional models, as they connect to smart meters or home energy management systems, enabling usage during off-peak hours.

'Smart devices don't just switch off during peak demand times; they optimize energy usage in subtle ways,' states the DOE. 'For instance, your air conditioner may operate less frequently, or your water heater may adjust its heating cycle to function when energy costs decrease, all without compromising performance. You can even schedule your laundry or dishwasher to run when electricity rates are lower.'

5. Invest in an Energy-Efficient Dishwasher

Dishwashers are among the most energy-hungry appliances, so it's important to always use them with a full load and select the eco program when available.

As mentioned earlier, choosing appliances with eco settings can lead to significant savings. These settings often use less water and allow for cold washes that save energy.

6. Select an Eco-Friendly Refrigerator

If you're picking a refrigerator, note that this is typically the most energy-intensive appliance in your kitchen. To reduce energy use, avoid overloading, limit door openings, and activate 'holiday mode' when away.

Consider investing in an app-controlled smart fridge. It can alert you if the door is left open and optimize cooling when you return from shopping.

7. Make Cooking More Efficient

Modern ovens are well-insulated to prevent heat loss and generally have favorable energy ratings. However, there are features to look for that enhance efficiency.

'Rapid heat-up options are convenient, but for those with time, the eco mode is more energy-efficient, gradually heating food without an initial surge,' suggests a product manager from a major appliance brand.

Cooking multiple dishes simultaneously and minimizing door openings also boosts energy efficiency. 

Using induction hobs is another great option as they heat only the base of the pan, reducing heat loss significantly.

8. Kettle or Boiling Water Tap?

When choosing between an electric kettle and a boiling water tap, be mindful of overfilling your kettle. Alternatively, consider a boiling water tap, which is more energy-efficient. A typical kettle uses 2,200W to boil 1.7 liters of water multiple times a day, while a boiling water tap only needs 10W per day to keep water ready.

9. Optimize Laundry Day Efficiency

Energy-efficient washers can lower both energy and water expenses, and while they may have a higher upfront cost, they can save around $160 over their lifespan.

'To maximize savings, wash only full loads and use lower temperatures,' recommend specialists in energy savings.

Tumble dryers consume a lot of energy, so finding an efficient model is crucial. You could save up to $782 on energy bills over its lifetime. Look for models with sensors that indicate when clothes are dry to prevent unnecessary usage, and consider switching to electric heat pump or gas dryers for improved efficiency.

What Appliances Use the Most Energy?

Cooling and heating appliances typically consume the most energy, including refrigerators, air conditioning units, home heating systems, and ovens. Laundry appliances also rank high on the energy consumption list.

How Can I Improve My Appliances' Efficiency?

Even energy-efficient appliances can waste power if left on standby, costing the average household around $70 annually. 

'There are various products available, such as standby savers, which allow you to turn off all appliances in one action, with some featuring timers or single off-switches,' energy experts advise.
