Green Powered & Energy Efficient

100% Green Powered

Our facility is powered by 100% green sourced power as specified by Scottish Power (the supplier) and as regulated by Ofgem.

Energy Efficient Datacenter

Highly energy efficient datacenter, with a PUE rating of between 1.2 and 1.3 and environmental management policy externally assessed to ISO 14001 standards.

Sensible Green Policies

Our environmental policy aims to reduce waste, encourage recycling and avoid all unnecessary travel. Many of our staff also enjoy working from the comfort of their own homes.

Picture the scene...

It's a Sunday morning. You've sat down with your coffee and croissant, and you decide to read the news online, check your email or watch the latest YouTube sensation.


This little scene may seem innocent enough, but did you know that what you've just done had an environmental impact? Would you be surprised to learn that it contributes to a beast that produces an enormous and ever-growing amount of carbon?

Real-World Mechanics

As ephemeral as it all seems, it's easy to forget the real-world mechanics that go into keeping the Internet running. A web site is housed on a server in a datacentre - a building packed top to bottom with servers which power the web pages, videos, online applications and downloadable files that make the modern online experience possible.

All these servers require electricity to keep them powered up, and then almost as much again to keep them cool. To generate much of that electricity, fossil fuels like coal and gas are usually being burned.

The internet is a filthy, carbon-emitting monster.

The Kualo Way

We're passionate about web sites, but moreover, we're passionate about ensuring they don't damage our environment.

100% Renewable Power

This starts with only using green power. Unlike many datacentres, our facility is powered by 100% green sourced power as specified by Scottish Power (the supplier) and as regulated by Ofgem. Currently this is 100% wind powered but projects are in development for wave and tidal power as well.

Energy Efficient Data Center

Even renewable energy is precious - so the next step in the process is to ensure that use of that electricity is also kept to an absolute minimum, which starts with intelligent datacentre design.

Our primary hosting facility, Centro, is not only powered entirely by renewable energy, but has also been built from the ground up to be extremely energy efficient. Part of The Green Grid industry body, Centro complies with the EU datacentre code of conduct and is audited and certified to ISO 14001 (Environment Management) standards. The facility achieves a class-leading PUE (Power usage effectiveness) of 1.2, making it one of the most efficient hosting facilities in service today.

In the typical datacentre, a huge amount of energy is used to keep the servers cool - generally this is because inefficient design principals have been employed. In the vast majority of datacentres, the server rooms are kept exceedingly cold, but the servers sit there blowing out a heap of hot air back into the room. A huge amount of energy is thereby wasted constantly having to re-cool that hot air again, causing the cooling systems to work harder and consume more power than they ought to.

In Centro, the hot air expelled from the servers is contained and directly extracted from the building, meaning the cooling systems can operate much more energy efficiently. The super efficient water-based chillers additional use 'free cooling' technology, which means that when it's cool enough, the outside air can just be pumped through rather than waste energy keeping the chillers running at full-speed.

Sensible Green Policies

Being environmentally conscious is at the heart of everything we do. Along with a super-efficient, green powered datacenter, as a company we also:

  • Use energy efficient servers with high-efficiency power-supplies and smart sensors to control fans so that they only provide cooling when required.
  • Cycle out older server hardware to newer more efficient technology as it becomes available
  • Operate a completely paperless system with all customer invoices, specs and receipts sent out in electronic format
  • Avoid printing unnecessary documents and recycle all unneeded paper
  • Use modern, low-power PCs throughout the office that use similar technologies to what we deploy in our servers
  • Encourage staff to work from home to minimise unnecessary commuting
  • Avoid all unnecessary travel
