The evaluation of the EU Energy Labels: A clearer system for consumers
The EU Energy Label has undergone significant updates to provide consumers with a clearer and more transparent understanding of product efficiency. Initially introduced in the 1990s, the label used an A+++ to D scale, which became increasingly complex as more products reached the top-tier ratings. In March 2021, the labeling system was revised to a simpler A-G scale , making it easier for consumers to compare energy efficiency across different appliances.
With these updates, consumers can now make better-informed decisions when purchasing households appliances, ensuring greater savings and enviromental benefits. Additionally, the revised system encourages manufactures to develop even more efficient products by setting highter benchmarks for top ratings.

Monitor appliance usage - record how many hours a day you use major appliances like the washing machine, air coditioner, or TV and identify devices on standby mode (e.g., chargers, computers etc.) 3. Track your thermostat settings (e.g., is it set at 22°C all day?)
Step 7
- What worked well?
- What could be improved?
- New habits to maintain?
- Additional upgrades to consider?
Step 4
- Lighting: Switch to LED bulbs, use natural light where possible.
- Heating/Cooling: Insulate windows and doors, adjust thermostat settings.
- Appliances: Upgrade to energy-efficient models, use smart power strips.
- Behavioral Changes: Turn off lights, unplug devices, reduce hot water use.
Step 3
- Are lights left on when not needed? - Are energy-efficient bulbs installed?
- Are windows and doors well-insulated? - Are thermostats set efficiently?
- Are appliances unplugged when not in use? - Are older, less efficient models still in use?
- Are devices left on standby mode?
Step 3
1. Inspect the attic, walls and floors for proper insulation
2. Look for gaps in insulation that cause heat loss

4. Laundry & Dishwashing
1. Wash full loads in dish washers and washing machines to maximize efficiency.2. Use cold water settings for laundry – 90% of the energy in washing machines is used for heating water. 3. Air-dry clothes instead of using a dryer whenever possible.
Step 6
1. Identify older, inefficient appliances 2. Look for Energy Label ratings (EU labels from A to G) 3. Unplug devices when not in use to reduce standby power
Quick Info
A family using smart lighting, a smart thermostat, and an energy monitoring system reported a 30% reduction in electricity consumption over a year.
1. Lighting & Electronics
1. Turn off lights & devices when not in use instead of leaving them on standby mode.2. Use natural light whenever possible – open blinds during the day in winter to warm rooms naturally. 3. Plug appliances into smart power strips to eliminate phantom loads.
Step 1
Step 4
1. Check HVAC filters and replace them if they are dirty 2. Inspect ducts for leaks or blockages 3. Set thermostats for optimal energy use
Step 1
Examine your energy bills over the past year to identify patterns or spikes in usage. This can help pinpoint periods of high consumption and potential inefficiencies.
Step 2
- Monthly Energy Bill (€):
- Average kWh Consumption:
- Main Energy Sources (Electricity, Gas, Oil, etc.):
- Appliances and Devices:
- Major Appliances: (e.g. refrigirator, washing machine, water heater) - Lighting: (LED, CFL, or incandescent) - Heating and Cooling Systems: (cental, split units, radiators) - Electronics: (TVs, computers, chargers)For example
1. Turn off lights when leaving a room - since unnecessary lighting increases electricity consumption and shortens bulb lifespan.2. Unplug devices when not in use - since even in standby mode, appliances like TVs, microwaves and chargers consume energy. 3. Optimize curtain and window use for natural temperature control - since sunlight can naturally warm your home in winter, while blinds or reflective curtains can block excess heat in summer, reducing heating and cooling costs.
Step 5
- Monthly Energy Savings Target (€ or kWh): (set a target on your own)
- Specific Actions to Implement:
- Example: Reduce thermostat settings by 1°C. - Example: Use cold water for laundry.- Expected Impact:
- Lower energy bills - Reduced carbon footprint - Improved comfort and efficiencyStep 5
1. Identify inefficient bulbs (incandescent, halogen) 2. Replace with LEDs 3. Use motion sensors or timers for automatic shutoff
For example
2. Evaluate the Impact of your New Habits
1. Check your New Energy Bill
Step 2
1. Check windows, doors and vents for drafts2. Use a candle or smoke test to detect air movement near cracks3. Seal leaks with caulk or weatherstripping
2. Heating & Cooling
1. Adjust thermostats to recommended energy-saving settings (20-21 °C in winter and 25-26°C in summer) 2. Use programmable thermostats to optimize heating and cooling schedules 3. Seal doors and windows to prevent heat loss.
5. Refrigerator Best Practices
1. Defrost regularly to maintain efficiency.2. Keep the fridge away from heat sources (e.g., ovens in direct sunlight) to prevent overworking. 3. Set the fridge temperature to 3-5°C and the freezer to -18°C for optimal energy use.
Key Updates to the EU Energy Labelling System
3. Kitchen Practices
1. Use lids on pots to cook faster and reduce energy waste (efficient practices).2. Turn off the oven 10-15 minutes before cooking finishes – residual heat completes the process (efficient practices). 3. Use energy-efficient appliances (e.g., induction cooktops).
Step 6
- Start Date:
- Next Check-In Date:
- Progress Notes:
- Canges noticed in energy bills - Comfort improvments - Challenges encounteredFor example
After implementing energy-saving habits and comparing your energy bills, take a moment to reglect on the impact these changes have on both your energy consumption and overall home comfort.
1. Energy Use Awareness
2. Home comfort Enhacements
For example
1. Check your energy bill - look at the total kWh used last month and note down the cost of your energy bill to compare later.2. Monitor appliance usage - record how many hours a day you use major appliances like the washing machine, air coditioner, or TV and identify devices on standby mode (e.g., chargers, computers etc.) 3. Track your thermostat settings (e.g., is it set at 22°C all day?)
Step 7
Step 4
Step 3
- Lighting
- Are lights left on when not needed? - Are energy-efficient bulbs installed?- Heating and Cooling
- Are windows and doors well-insulated? - Are thermostats set efficiently?- Appliance Use
- Are appliances unplugged when not in use? - Are older, less efficient models still in use?- Standby Power
- Are devices left on standby mode?Step 3
1. Inspect the attic, walls and floors for proper insulation 2. Look for gaps in insulation that cause heat loss
