EcoHost Checker
Is your website
hosted on green energy?
Check any domain against The Green Web Foundation database to find out if your hosting provider runs on renewable energy. Your server's energy source is the foundation of a sustainable website.

Why Green Hosting Matters
Data centres are responsible for approximately 1-1.5% of global electricity consumption. Choosing green hosting is one of the most impactful decisions for digital sustainability.
Of Global Electricity
Data centres consume roughly 1-1.5% of global electricity. As more services move online, this is growing by 15-20% annually.
Of Global CO2 Emissions
The ICT sector contributes around 2% of global emissions — comparable to the aviation industry. Data centres are a major share of this.
Always On
Unlike offices that power down at night, servers run continuously. This makes their energy source critically important — every hour counts.
Cooling Overhead
Up to 40% of a data centre's energy goes to cooling. Green providers often use innovative cooling (free air, water) to reduce this overhead.
What You Can Do
- Check your current host using the Green Check tab above
- Switch to a green provider if your host isn't using renewable energy
- Ask your hosting provider about their energy sources and sustainability plans
- Combine with code optimisation — use our Carbon Auditor to reduce page weight too
- Choose a local data centre — shorter network paths mean less energy in transit
- Use a CDN with green edge nodes to serve users from nearby locations
Green hosting is the foundation of a sustainable website. Even the most optimised code running on fossil-fuel-powered servers has a significant carbon footprint.
