* Giant fans pull in cold air to cool the vast racks of servers in center the size of six football fields
* Dozen hydro-electric plants operate on nearby rivers, providing a reliable and renewable power source

The main building is the size of six football fields, and is so big that engineers move around on scooters.

Mark Zuckerberg has given a rare glimpse inside one of Facebook's secretive server farms.

The Facebook boss said he is going to reveal more pictures from Facebook's facilities around the world.

To kick off the project, he revealed a stunning series of pictures of the firm's gigantic Luleå data center in Sweden.

'Over the next few months, I'm going to start posting some rare photos of the most advanced technology Facebook is building around the world,' Zuckerberg posted.

The Luleå data center opened in 2013, and was Facebook's first outside the US.

It is located deep in the forests of northern Sweden. 

'It's a key part of our global infrastructure, and it uses a variety of local natural resources to increase efficiency and save power,' said Zuckerberg.

'The small town of Luleå is less than 70 miles south of the Arctic Circle, and it's typically pretty cold. 

'The temperature in the area is below 50 degrees most days, so we use large fans to pull in the outside air to naturally cool the thousands of warm servers that line the center's broad hallways.'

Companies rely on additional data centres not only to provide faster connections for people nearby, but also as backup in event of a system failure.

A dozen hydro-electric plants operate on nearby rivers, providing a reliable and renewable power source. 

The whole system is 10% more efficient and uses almost 40% less power than traditional data centers, Facebook claims.

The equipment is reduced to its basics so it runs cooler. It can also be easily accessed and
repaired quickly. A few years ago, it took an hour to repair a server hard drive. At Luleå, that's down to two minutes, Facebook said.

'Inside, the main building is the size of six football fields,' said Zuckerberg. 

'Nearly all the technology in the facility, from the servers to the power distribution systems, is based on Open Compute Project designs as well.

The center opened in 2013, and was Facebook's first outside the US. It is located deep in the forests of northern Sweden.

'You probably don't think about Luleå when you share with friends on Facebook, but it's an example of the incredibly complex technology infrastructure that keeps the world connected. 

'I'm looking forward to sharing photos of more of our advanced technology soon.'

WHAT DO DATACENTERS DO-AND WHY DO THEY USE SO MUCH POWER.

Internet companies such as Facebook use huge 'server farms' such as this proposed plant to store and manage data.

The plants are filled with cupboard-sized racks of computer servers that store and move data such as photos. These slightly eerie, heavily guarded facilities are where sites such as Facebook and Google 'live'

The high-power computer equipment generates huge amount of heat - most data centres use chiller systems to stay cool.

Nordic countries now sell plants on the basis that their frosty locations will help cool computer equipment. Google already has a plant in Finland in a disused paper mill.

Facebook is also building new data centres in America - the more an internet company has, the better, as it has 'back-up' facilities in case of a failure.

The huge data center began on the back of this paper napkin. Late one night, while traveling, engineer Jay Park sketched his vision for a system that streamlined the way power moves from the local utility grid to our servers.

Facebook didn't give the price of its investment, but Lulea officials have previously projected construction costs of up to 5 billion kronor ($760 million).

'We knocked on doors at Facebook's head office (in Palo Alto, California) and today they're moving in to Lulea — this is huge, really huge,' said Matz Engman, who heads the Lulea Business Agency, a public-private partnership working to attract businesses to the region.

With winter temperatures well below freezing and summertime highs that rarely climb above 80F (25 degrees Celcius), Lulea has used its frigid climate as a selling point in its efforts to establish itself as a hub for server farms.

Look at these racks, the network devices, the cabling. Everything is like reference model!' - Max Zavyalov, Network Engineer in Edge & Network Services team

Other Nordic cities have adopted similar strategies.

In 2009 Google purchased a paper mill in Hamina, southern Finland, and turned it into a data center, using seawater from the Baltic Sea for its cooling system.

Servers inside data centers are the backbone of Internet services such as Facebook.

The servers store and transmit billions of status updates, links, photos and all the outside apps used by Facebook's members.

There is no more efficient data center in the world,' said- Jay Park, VP of Data Center Design and Construction
