The refrigerator hums, the washing machine runs, and the dishwasher finishes its cycle. Most of us rarely think about the electricity behind these everyday tasks. Yet together, household appliances make up a large part of the world’s power demand. Small choices at the point of purchase can shape energy use for many years.
One of the simplest tools for making those choices is the energy label. It is easy to ignore and easy to misread. This article explains what energy labels and efficiency standards are meant to do, how to read them with care, and where their limits lie.
Appliances Use More Electricity Than Many People Realize
According to the International Energy Agency (IEA), electricity consumption by household appliances reached over 3,000 terawatt-hours in 2019. That was about 15 percent of global final electricity demand, or roughly one quarter of the electricity used in buildings. Refrigerators make up a meaningful share of that total.
Better design has helped. Appliance efficiency rules have made the average new refrigerator, washing machine, or television far less hungry than its predecessor, while households have added more devices, from mobile phones to tablets and routers. Gains in efficiency can be offset when the number of devices keeps growing.
How Standards and Labels Work
Governments use two main tools to improve appliance efficiency. Minimum energy performance standards set a threshold that products must meet to be sold in a market. Energy labels help buyers compare products by showing how much energy each one uses.
The IEA reports that more than 120 countries have introduced or are developing mandatory standards and labels for key appliances. It also says that long-running appliance policies are saving up to 15 percent of total national electricity consumption in some countries. Labels are not a cure-all, but they give shoppers information that would otherwise be hard to find.
Label designs differ by region. In the European Union, for example, labels were rescaled on 1 March 2021 to use a simple A to G scale, a change the European Commission introduced to make the ratings clearer, since older products had crowded into the top classes.
Reading a Label With Care
A label is a good starting point, but it works best alongside other information. Resources such as Rate Red help readers explore home appliances, understand their features, and compare options, which can add useful context to what a label shows.
When you read a label, keep a few points in mind:
- Ratings usually compare products of the same type, so a rating on one appliance cannot be compared with another type.
- Capacity matters. A larger machine may use more energy in total, even with a strong rating.
- Labels estimate typical use. Your own habits may differ.
- Energy use is only one part of a product’s value. Labels say little about how long a product will last.

Reading a shopping page or a label is only part of the picture. The figure on a label reflects a standard test cycle, so it tells you what the appliance uses under controlled conditions rather than what it will use in your kitchen. Comparing two models of the same capacity is where a label earns its keep; comparing a compact dishwasher with a full-size one, or a heat-pump dryer with a condenser model, tells you almost nothing.
Looking Beyond the Label
Some details only appear in daily use. How loud is the machine? Is a filter easy to clean? Do owners report problems after a few years? Reading balanced fan comparisons can help fill these gaps, as long as you look for repeated patterns rather than single opinions.
It also helps to be realistic about replacement. A newer model may use less energy, but making a new appliance has its own environmental footprint. If your current appliance still works well and is safe to use, replacing it is not always the better choice. When it does reach the end of its life, choose a model that fits your household’s real needs, and use an official collection point for the old one.
Habits That Support the Technology
The IEA points out that efficiency gains work best when they are paired with changes in how people use appliances. Technology can only do so much. A few small home upgrades that lower electricity use make a measurable difference:
- Choose the right size for your household instead of the biggest one available.
- Run full loads of laundry and dishes when practical.
- Switch off devices that do not need to stay on standby.
- Clean filters, coils, and seals as the manufacturer advises.
- Keep appliances in good working order so they run as designed.

A Small Choice With a Long Reach
Energy labels will not solve the world’s energy challenges. They do, however, give households a way to see something that is usually hidden. When combined with careful research, realistic expectations, and sensible habits, they can guide better decisions.
The next time you shop for an appliance, take a moment to read the label closely. Think about how you will use the product, how long you hope to keep it, and what its running costs might be. A few minutes of attention at the store can influence years of everyday energy use at home.
