It is incredibly easy to think of your website, and the web as a whole, as an invisible "cloud" floating in a digital space. But the reality is much more tangible. Every website is powered by physical resources: servers, routers, expansive data centres, and the heavy-duty cooling systems required to keep them running. All of this physical infrastructure demands a massive amount of electricity. As website owners, considering where that power comes from and how efficiently it is used is the first step toward a greener internet.
So, what does a sustainable physical foundation for your website actually look like? Let's take a look inside our Green Hosting...
The London-based data centre which houses our Green Hosting servers, routers, and cooling systems runs entirely on renewable energy. This power is purchased directly from wind, solar, and hydro sources.
However, true sustainability is about more than just sourcing green power, it is about respecting it. Our data centre isn’t wasteful with that green energy. In fact, it has achieved an outstanding Power Usage Effectiveness (PUE) of 1.09, making it one of the most efficient data centres in the world.
By only using as much power as you need, reducing waste, and designing systems that require less power from the start, we reduce the demand on precious natural resources and the infrastructure that supplies it. This, in turn, can allow for more widespread use of renewables and potentially lower energy costs. For us, it always comes back to being part of a wider movement for positive change, for people and the planet.
How does our data centre achieve this incredible level of efficiency? It comes down to its intelligent design and build.
Firstly, servers get very hot. To keep them cool, the facility employs ‘evaporative cooling’, which works by running air and water via EcoCooling units. Simply put, outside cool air is passed through water which evaporates and makes the air even cooler. On cold days (which are quite common in the UK!), the water isn’t even needed, and on hot days it can easily handle the strain. Most importantly, this type of cooling uses no refrigeration or harmful chemicals.
In addition, the data centre applies ‘cold aisle containment’. This clever design ensures that the hot air produced by the servers and the freshly cooled air are kept strictly separate, meaning the cooling process isn’t compromised.
And it doesn’t stop there. This facility has plans to add its own roof-mounted solar panel array, providing additional on-site renewable energy.
Here at Green Hosting, we work to make a positive impact by diverting websites and e-mail services (hundreds to to date) away from fossil fuel-powered hosting services to our 100% renewable energy-powered service. We also continue to proudly promote renewable energy hosting and our clients who choose it.
Switching to Green Hosting means that our clients’ websites are directly helping to reduce greenhouse gas emissions, but that’s not all. Together, through our consumer power, we are sending a strong message to utility and data centre companies that website owners want more clean energy.
