How Clean Is Your Electricity?
Your electricity source shapes the carbon cost of everything you do online. The same activity can produce very different emissions depending on your country's energy grid.
Sweden / Finland / Luxembourg
~60 gCO₂/kWh
France
~85 gCO₂/kWh
UK
124 gCO₂/kWh
EU average
213 gCO₂/kWh
Netherlands
~284 gCO₂/kWh
Germany
~385 gCO₂/kWh
US
384 gCO₂/kWh
Global average
473 gCO₂/kWh
China
560 gCO₂/kWh
Australia
~500 gCO₂/kWh
Poland / Estonia
700+ gCO₂/kWh
India
708 gCO₂/kWh
Only 30% of data centre energy comes from renewables today. Increasing this to 80-90% would cut the footprint of every digital activity by more than half.

What You Can Do
Six high-impact actions you can take today.
Delete unused files and emails
Every forgotten file sitting in the cloud consumes energy 24/7. Cleaning up is the easiest win.
Stream in lower resolution
Dropping from 4K to 1080p can cut streaming emissions by up to 86%. You probably won't notice the difference on a phone screen.
Switch to a sustainable energy provider
If your electricity comes from wind or solar, every digital activity you do is dramatically cleaner.
Keep your devices longer
Up to 80% of a smartphone's lifetime carbon cost comes from manufacturing. An extra year of use makes a real difference.
Schedule heavy AI tasks during daytime
Solar generation peaks midday. Running large AI workloads then means your queries ride on cleaner energy.
Close unused apps and background processes
Apps running in the background consume power around the clock. Closing them reduces your device's energy draw and extends its lifespan.
