Energy Label Visualizer - EU Energy Ratings A-G

Energy Label Visualizer

Generate EU-style energy efficiency labels for appliances. Select an appliance type, energy rating (A-G), and consumption to visualize the label and calculate annual operating costs.

Typical Annual Energy Consumption by Appliance

Reference values for common household appliances. Actual consumption varies by model, usage, and efficiency rating.

Annual costs calculated at $0.12/kWh. Actual costs depend on local electricity rates and usage patterns.

Understanding EU Energy Labels

The EU energy label is a standardized system that displays the energy efficiency of appliances on a scale from A (most efficient) to G (least efficient). Introduced in 1995 and rescaled in 2021, the label uses intuitive color coding to help consumers make informed purchasing decisions.

• Class A (Dark Green): Most efficient. Uses the least energy for the same functionality. Lowest operating costs.
• Class B-C (Light Green to Yellow): Above average efficiency. Good balance between purchase cost and operating cost.
• Class D (Yellow): Average efficiency. Moderate energy consumption.
• Class E-F (Orange to Red): Below average efficiency. Higher operating costs over the appliance lifetime.
• Class G (Deep Red): Least efficient. Highest energy consumption and operating costs.

The label also displays annual energy consumption in kWh, making it easy to calculate operating costs by multiplying by your local electricity rate.

Why Energy Efficiency Matters

Energy-efficient appliances cost more upfront but save money over their lifetime through lower electricity bills. For appliances that run continuously (like refrigerators) or frequently (like washing machines), efficiency differences compound significantly.

10-Year Cost Example: Refrigerator

• Class A (200 kWh/year): $240 total energy cost over 10 years ($0.12/kWh)
• Class D (350 kWh/year): $420 total — $180 more expensive
• Class G (600 kWh/year): $720 total — $480 more expensive

If the Class A model costs $100 more than the Class G model, you break even in just over 2 years and save $380 over the appliance's 10-year lifespan. For high-consumption appliances like air conditioners or water heaters, savings can exceed $1,000 over the product lifetime.

How to Calculate Energy Costs

The formula for annual energy cost is straightforward:

Annual Cost ($) = Annual Consumption (kWh) × Electricity Rate ($/kWh)

Example: A refrigerator consuming 300 kWh per year at a rate of $0.12 per kWh:

300 × 0.12 = $36 per year

Find your local electricity rate on your utility bill (usually shown as cents per kWh or $/kWh). Rates vary widely by location, ranging from $0.08/kWh in some U.S. states to over $0.30/kWh in parts of Europe.

Frequently Asked Questions

What is an EU energy label?

An EU energy label is a standardized label that shows the energy efficiency rating of appliances on a scale from A (most efficient) to G (least efficient). The label uses color coding from dark green (A) to red (G) to make energy efficiency easy to understand at a glance. It also displays annual energy consumption in kWh and other relevant specifications like noise level or capacity.

How much does it cost to run a refrigerator per year?

A typical modern refrigerator with a Class A or B rating (200-300 kWh/year) costs $24-$36 per year to run at $0.12/kWh. An older or less efficient model rated Class D or lower (400-600 kWh/year) can cost $48-$72 annually. Energy-efficient models save $20-$50 per year compared to inefficient ones.

What is the difference between energy classes A and G?

Energy class A appliances are the most efficient and use the least electricity, while class G appliances are the least efficient. The difference in annual costs can be substantial. For example, a Class A refrigerator might cost $25/year to run while a Class G model could cost $100+ annually — a difference of $75 per year or $750 over 10 years.

How do I calculate annual energy cost?

Multiply the annual energy consumption (in kWh) by your electricity rate (in $/kWh). For example, an appliance using 300 kWh per year at $0.12 per kWh costs $36 per year to operate (300 × 0.12 = 36). You can find the annual consumption on the energy label and your electricity rate on your utility bill.

What appliances use the most energy?

Air conditioners (800-2,500 kWh/year) and electric water heaters (1,500-4,000 kWh/year) typically use the most energy, followed by clothes dryers (180-800 kWh/year), refrigerators (200-600 kWh/year), and dishwashers (220-450 kWh/year). For these high-consumption appliances, even small differences in efficiency ratings can save hundreds of dollars annually.

Is A+ better than A?

Under the old EU energy label system (pre-2021), A+, A++, and A+++ indicated higher efficiency than A. However, the EU rescaled labels in 2021 to use only A through G, making A the best rating again. Old A+++ appliances typically become B or C under the new scale. If you see A+ on a label, it's using the old system.

How much can I save with an efficient appliance?

Savings depend on the appliance type and usage. For a refrigerator running 24/7, upgrading from Class G (600 kWh/year) to Class A (200 kWh/year) saves 400 kWh annually — about $48 per year at $0.12/kWh, or $480 over 10 years. For high-consumption appliances like air conditioners, savings can exceed $1,000 over the product lifetime.
