How to spot energy efficient electronics in the EU

Since March 2021, the EU replaced the old A+++ to G scale with a cleaner A to G system. The key difference is that the new A-G label is deliberately strict. Products that previously earned an A+++ rating now typically fall into the C or D class, and the A class is intentionally left empty to give manufacturers a target to reach in coming years. This approach pushes innovation rather than rewarding yesterday's best.

Every new EU energy label includes a QR code you can scan to access the EPREL database, the EU's official product registry. There you'll find verified energy consumption data, noise levels, and technical specs. It takes seconds and gives you far more detail than the label alone.

For TVs and monitors, the label shows two key figures: SDR (standard dynamic range) and HDR (high dynamic range) power consumption. SDR reflects typical everyday viewing, while HDR applies when you stream 4K content with enhanced contrast. These two numbers can differ significantly, and most buyers only check one.

Here's what to look for on any EU energy label:

Efficiency class (A-G): Aim for B or higher where available
Annual energy consumption in kWh: Lower is better, regardless of class
QR code: Always scan it for full EPREL product data
SDR and HDR wattage (for displays): Compare both figures
Noise rating (for appliances): Often linked to motor efficiency

For deeper guidance on reading labels across product types, the energy label tips available on our blog break down each section clearly. You can also explore our sustainable electronics guide for a broader look at what sustainability means in practice. The display efficiency benchmarks published by the EU offer additional technical context if you want to go further.

Energy efficient TVs and displays

Televisions are one of the most used devices in any home, so efficiency here has real impact. The Peaq PTV 50GQU-5024C draws just 100W, making it one of the more frugal 50-inch options available. Sony Bravia models range from 79W for smaller LED sets to 257W for larger OLED screens, showing how screen size and panel technology both matter.

OLED panels produce stunning picture quality but tend to use more power than LED-backlit LCD screens, especially at high brightness. Automatic brightness control (ABC) helps by adjusting the screen based on ambient light. Most modern efficient TVs include ABC as standard, and it can reduce real-world consumption by 20 to 30 percent compared to fixed brightness settings.

Resolution also plays a role. A 4K display running HDR content can consume nearly twice the energy of the same screen in SDR mode. The power per dm² for displays dropped 37% to 1.0 W/dm² in 2020 due to EU regulations, with projections reaching 0.35 W/dm² by 2030, saving an estimated 51 TWh across the EU.

Model	Screen size	Typical wattage	Efficiency class
Peaq PTV 50GQU-5024C	50 inch	100W	B
Sony Bravia (LED, small)	43 inch	79W	C
Sony Bravia (OLED, large)	65 inch	257W	D

Key factors that drive TV efficiency:

LED panel type: Mini-LED and edge-lit models generally outperform full-array in efficiency
ABC enabled by default: Check this setting is on, not just available
Screen size match: Oversized TVs for small rooms waste energy constantly
HDR usage: Streaming in SDR when HDR isn't needed cuts consumption noticeably

Pro Tip: Choose a TV size suited to your actual viewing distance. A 75-inch screen in a small room doesn't improve your experience, but it does increase your electricity bill every single day.

Efficient refrigerators and kitchen appliances

Refrigerators run 24 hours a day, 365 days a year. That constant load makes efficiency improvements here more impactful than almost any other device. Dual-evaporator designs improve fridge efficiency by 7.2%, and modern refrigerators now use roughly 25% of the energy that comparable models consumed in the 1970s. That's not a small gain. It represents decades of compressor innovation, better insulation, and smarter airflow design.

Inverter compressors are the other major advancement to look for. Traditional compressors switch fully on or off, which wastes energy during the frequent cycling. Inverter compressors run continuously at variable speeds, matching cooling output to actual demand. The result is quieter operation and meaningfully lower electricity use over time.

Feature	Energy benefit	Label impact
Dual-evaporator	7.2% efficiency gain	Improves class by 1 step
Inverter compressor	15-20% less energy	Often required for A/B class
No-frost technology	Reduces defrost energy	Neutral to slight gain
Better door seals	Prevents cold air loss	Supports lower consumption

In the kitchen beyond the fridge, induction cooktops transfer up to 90% of energy directly to the pan, compared to around 70% for ceramic and roughly 50% for gas. That efficiency difference adds up across daily cooking. For ovens, models with convection fans distribute heat more evenly and allow lower temperature settings, cutting cook times and energy use together.

Key things to look for in kitchen appliances:

Inverter compressor label: Often listed in the product specs, not always on the label
EU energy class A or B for fridges: Anything below C warrants a closer look
Induction over ceramic: Faster, more efficient, and easier to control
Oven capacity matched to use: Larger ovens take more energy to heat

Pro Tip: When comparing fridges, check the annual kWh figure on the label rather than just the class. Two B-rated fridges can differ by 40 kWh per year depending on size and internal layout.

Our efficient kitchen appliances guide covers specific models worth considering, and if you want broader advice on saving on appliances without cutting quality, that resource is worth bookmarking.

Chargers, power supplies, and networked electronics

Chargers and power supplies are easy to overlook, but they add up. Every device left plugged in but idle draws power. The new EPS regulation (EU) 2025/2052 sets minimum efficiency standards for external power supplies, mandates USB-C interoperability, and is projected to deliver 3% lifecycle energy savings by 2035. That regulation covers the chargers shipped with laptops, monitors, and consumer electronics sold across the EU.

Standby power is a separate but related issue. Routers, smart speakers, and set-top boxes often sit in a low-power state for hours. Updated EU rules now cap standby and networked standby at 0.5 to 2W, saving an estimated 4 TWh per year by 2030 and delivering around €530 million in annual consumer savings across the EU.

EU regulations for standby modes are projected to remove the equivalent emissions of 140,000 cars annually from European roads.

What this means practically for your home:

Use USB-C chargers where possible: Newer universal chargers are more efficient and reduce adapter clutter
Check router standby specs: Many older models exceed current limits significantly
Smart plugs with scheduling: Cut power to devices that don't need to stay on overnight
Look for the EU EPS compliance mark: Confirms the charger meets 2025 efficiency standards

And if you're buying new chargers or accessories online, the safe electronics shopping guide helps you avoid counterfeit products that often fail efficiency standards entirely.

Comparison of energy efficient electronics: Which saves the most?

Not all efficiency upgrades deliver the same return. Here's a side-by-side look at the major categories, using empirical EU benchmarks including displays at 1.0 W/dm², washers at 40 kWh per 100 cycles, and standby below 0.5W.

Category	Typical annual use	Efficient model use	Estimated savings
Refrigerator (A class)	400 kWh	150 kWh	~250 kWh/year
TV 55 inch (B class)	180 kWh	90 kWh	~90 kWh/year
Washing machine (A class)	200 kWh	120 kWh	~80 kWh/year
Chargers and standby	80 kWh	30 kWh	~50 kWh/year

The numbers show that refrigerators offer the single largest household savings opportunity, largely because they run continuously. TVs come second, especially if you're replacing an older plasma or early LCD model. Chargers and standby devices seem small individually, but across a home with multiple networked devices, the total adds up quickly.

Key takeaways from the comparison:

Fridges first: The continuous runtime makes efficiency class critical here
TV size matters as much as class: A B-rated 75-inch uses more than a C-rated 55-inch
Charger quality affects daily waste: Cheap chargers often draw more no-load power
Combined upgrades multiply savings: Replacing three categories together can cut home electronics energy use by 30% or more

What really defines energy efficiency in 2026: Beyond the labels

Energy labels are a useful starting point, but they don't tell the whole story. A TV rated B in the showroom can behave more like a D in your living room if HDR is always active, brightness is set to maximum, and it runs eight hours a day. The label measures a standardized test condition, not your actual usage pattern.

We've seen this gap widen as screens get larger and content gets more demanding. The 20 TWh in display savings achieved by 2020 regulations are real and significant. But those gains can be partially offset at the household level by behavioral choices that the label simply can't account for.

The honest advice is to treat the label as a filter, not a final answer. Use it to eliminate poor performers, then dig into real consumption data via EPREL and manufacturer specs. Combine that with mindful habits: enable ABC, match screen size to room, and put networked devices on smart plugs. That combination, label class plus real data plus smart habits, is what actually delivers savings.
