The Internet of Things in 2020

We’ve previously posted about the Internet of Things and the pace at which new devices are connected to the internet. However, this archived (but still relevant) infographic does a much better job at visualizing this exponential growth.

There are roughly 10 billion devices connected to the web today. By 2020, Intel estimates there will be 31 billion devices connected. Here are some other predictions for the IoT in 2020:

  • IDC forecasts the market to be worth $7.1 trillion
  • Cisco has estimated by then, 5 billion people and 50 billion devices will be connected
  • Morgan Stanley feels the number should be even higher: up to 75 billion devices connected in 2020

Regardless of whether it is 30 or 75 billion, that number is still huge – and investors need to stay on top of this development. There is no shortage of opportunities!

Can Data Centers Be Sources of Sustainable Heat?

Data centers produce a staggering amount of heat, but what if instead of treating it as waste, we could harness it instead?

Can Data Centers Be Sources of Sustainable Heat?

Data centers support the modern technologies on which we rely, but also generate incredible amounts of heat as waste. 

And since computers tend to be very sensitive to heat, operators go to great lengths (and expense) to get rid of it, even relocating to countries with lower year-round average temperatures. But what if instead of letting all that heat disappear into thin air, we could harness it instead?

In this visualization, we’ve teamed up with HIVE Digital to see how data centers are evolving to recapture and recycle that energy.

How Much Heat Does a Data Center Produce?

To get an idea how much heat we’re talking about, let’s imagine a mid-sized cryptocurrency operation with 1,000 of the most energy-efficient mining rigs on the market today, the Antminer S21 Hydro. One of these rigs needs 5,360 watts of power, which over a year adds up to 47 MWh.

Multiply that by 1,000 and you end up with over 160 billion BTU, which is enough energy to heat over 4,600 U.S. homes for a year, or if it happens to be Oscar season, enough heat to pop 463,803 metric tons of popcorn. Less if you want melted butter on it. 

How Waste Heat Recycling Works?

At a high level, waste heat is recaptured and transferred via heat exchangers to district heating networks, for example, where it can be used to provide sustainable heat. Cool air is then returned to the data center and the cycle begins again.

Liquid cooling is by far the most efficient means of recapturing and transporting heat, since water can hold roughly four times as much heat as air.

Data centers around the world are already recycling their waste heat to farm trout in Norway, heat research facilities in the U.S., and to heat swimming pools in France.

A Greener Future for Data Centers?

Waste heat recycling has so far been voluntary, led by operators looking to put their operations on a more sustainable footing, but new regulations could change that. 

Amsterdam and Haarlemmermeer in the Netherlands require all new data centers to explore recycling their waste heat. In Norway, they require it for all new data centers above 2 MW, while Denmark has taken a carrot approach, and developed tax cuts and financial incentives. And in late 2023, the EU Energy Efficiency Directive came into force, which will require data centers to recycle waste heat, or show that recovery is technically or economically infeasible. 

With Europe leading the way, could North America be very far behind?

HIVE Digital Provides Sustainable Heat

HIVE Digital is already recycling waste heat from its data center operations in Canada and Sweden. 

Their 30 MW data center in Lachute, Québec, is heating a 200,000 sq. ft. factory, while their 32 MW data center in Boden, Sweden, is heating a 90,000 sq. ft. greenhouse, helping to provide sustainably grown local produce, just one degree short of the Arctic Circle.
