If you give your heat away for free, no one wants it. Put a price on it, and customers will form a line

Projects in the US and China have shown that data centers underwater could be more efficient than those on land. But how do you build them?

Data center diesels don’t have to run on fossil fuels. There’s a recycled product on offer

Covid-19 and supply chain issues are driving up interest in circular thinking for servers and networking gear, but will hyperscalers and hardware-as-a-service OEMs make it the norm?

What’s next for energy efficiency metrics in the data center industry?

Digital Metalla hopes to ape Norway’s Lefdal Mine and create a secure underground facility in a disused Sardinian mine

We talk to the former Norwegian politician who wants to make sure that energy doesn’t get wasted

Two-phase liquid cooling has finally arrived. Vendors are making purpose-built liquid cooled servers

A new cooling technology debuted at COP26 - one which uses thermal energy to create vibrations that cool systems better

Is it possible to run a conventional cooling system - but use water instead of harmful refrigerant gases? We found a firm that thinks so

Could the answer to a stable grid be literally all around us?

Could waste data center energy be stored by lifting concrete blocks?

A handful of companies have data centers at feeding on oil well gas flares. Do their environmental claims stand up?

Data centers need a steady source of power, with no greenhouse emissions. Could nuclear power be the answer?

We don’t know how much water data centers use. We just know it’s a lot

Research in technology and renewable energy in Singapore could blaze a path for more sustainable data centers around the world

As the country experiences a shift to the cloud, demand is booming

Long-term deals from large suppliers might insulate operators from the worst for now, but for how long?

Can backup generators switch to vegetable-based oil, and go green without compromising operations?

An EU-funded project built a data center with a PUE of 1.0148. Can that be translated to the real world?

Whether strawberries, cabbage, or cannabis, indoor farms are increasing in number. Will they soon start competing for the same space and power as data centers?

Keeping up with the cryptocurrencies

A land-based farm has finally produced plate-sized lobsters- thanks to a data center

While the hyperscalers have the scale and technical nous, deploying AI en masse is still an ongoing effort for most data center operators

Sustainability gains through energy efficiency will eventually plateau, but there’s much work to be done around the carbon footprint of building materials

Batteries will power the next decade, but companies need to ensure that their supply is as sustainable and ethical as they claim

Europe hopes to eliminate its net emissions by 2050, while the US is still getting its act together. Data centers want to lead the way

Despite the increased efficiency of battery power and renewable energy, data center operators still have diesel generators out back. That may be changing
