20i go green, with 100% renewables and power-efficient servers

20i have announced their move over to greener energy.The independent hosting provider – which recently opened a new data center in the USA – achieved this through a combination of the use of 100% renewable energy and energy efficiency.

All the 20i web servers are now powered by 100% renewable energy. That means the power used to host websites or virtual private servers is from an energy source that won’t be depleted.

In layman’s terms, most often that will mean wind and solar power, but can also include things like tidal, geothermal or wave power.


If renewable energy isn’t being used to power web servers, it increases the amount of ‘clean’ energy available to the grid. Having power-efficient servers also mean that web hosting prices can be kept low at a time when energy prices are skyrocketing.

20i’s web servers have a Power Usage Effectiveness (PUE) as low as 1.12. This measure – where lower is better – is the industry standard for how efficiently a data centre uses its power. In general, other ‘green hosts’ have a PUE of 1.2 or more.

Their unique autoscaling cloud hosting technology also has a part a play. It can offer the resources of an entire hosting platform to busy websites instantly – instead of just a single server. However, it also means that when a site isn’t busy, it won’t keep providing those resources unnecessarily. This instant scalability saves energy.

They’re also careful to cycle-out older server hardware to newer, more efficient technology as it becomes available.

Why did they make the change now?

Writing on the 20i blog, they say “The internet uses a lot of power. It’s estimated that data centres are responsible for between 1% and 3% of global energy use. This causes greenhouse gas emissions, and so contribute to climate change.

Up to now, it was difficult to find a provider that would offer the right level of reliability and performance that we’re known for.”

Now that they’ve found the right provider, they’re able to make the switch to green hosting.

Other green policies

20i encourages a climate-positive workforce. Their UK headquarters are powered by solar power, is ‘paperless’ and uses efficient LED lighting. Unnecessary travel is discouraged through hybrid work patterns, a cycle-to-work scheme and all materials are recycled.
