What will happen to the technology industry in an age of expensive energy?
The technology industry has grown up in an age of cheap and abundant energy, and that has shaped, deeply and fundamentally, the way it sees the world, what it chooses to make, and how it designs what it does. You have to think only of the short lifespan of the devices, the fact that they are discarded, not upgraded, when technology moves on; or the emerging service designs based on the world of the cloud; and always on, on demand access. But the age of cheap and abundant energy is coming to a close. It is about to become scarcer and more expensive. How does the technology energy need to respond?
It’s worth, quickly, making the case about energy, for not everyone believes this. John Michael Greer, in his book The Ecotechnic Future, uses the analogy of a group of field mice who find one day that someone has dumped a huge pile of grain in a corner of their field. They eat it and multiply, until the grain starts to run out.
The fieldmice’s grain is the same as our discovery of cheap fossil fuels – as the moment of peak oil approaches, and as reports of ‘peak coal’ gain credibility. Of course, humans are smarter than mice, and there is a strong view that we’ll be inventive enough to solve such problems. Greer is more sceptical:
Industrial civilization had its day in the sun [he writes] because, in a world where fossil fuel could be had for the digging or drilling, the industrial mode of production was more efficient than its rivals, and enabled the communities that embraced it to prosper at the expense of those that did not.
And the research suggests that technology delays the moment of impact, it doesn’t avert it. (I’ve written about this before). Oil itself is getting tougher to find and extract, as the Deepwater Horizon disaster showed. Renewables may help, but not at the scale necessary over the next decade, or even two. And so on. Even the International Energy Agency, which reports to governments and largely draws on figures for official reserves, sees a rapid decline in oil production from conventional sources, and estimates of large increases in prices are increasingly widespread. Set against that the global energy consumption of the internet is estimated at 3-5%, but growing very rapidly. The entire global transport industry takes around 25%, by way of comparison.
Making computers and phones is highly energy intensive
This consumption, though, is only half the story. The production of computers and module devices is one of the most energy-intensive in the world, as Low Tech Magazine has explained. All of the precision engineering, in large complex fabrication plants, means that the energy required to make each device (known as the “embedded energy”) is huge. There’s not enough work been done on this, but Low Tech magazine calculated that the energy required to make just the memory chip in a laptop exceeded the amount of energy consumed by the computer in its entire lifetime, typically three years. Each successive generation of fabrication plants is significantly more energy intensive than the last.
There are other hazards here. In the near-term, routine power cuts are likely even in places where they have been the exception, unless there is implausibly rapid reduction in demand for power. And sitting behind this is a resources threat: many of the materials (opens pdf) needed to make high-tech devices are scarce and found in areas which are difficult to access, for political or geographical reasons. Some are simply running out.
Of course, the industry has been responding. The big ICT companies are finding ways to reduce the energy consumption of servers. Intel and other chip companies are looking to make energy efficient chips. Apple has been greened, apparently slightly reluctantly. But reducing the sustainability impact of the existing business model will not have sufficient impact. The tech industry may have to rethink itself from the bottom up.
In what follows, I will try to sketch out what a sustainable technology sector might look like in an age of expensive energy.
The re-usable device
But the biggest story here is about moving beyond the disposable device towards the re-usable device. The notion that you throw away something when it needs an upgrade is an inherently 20th century idea. If you think of a computer or mobile as a bundle of highly expensive energy, in an age of energy scarcity it becomes an absurd one. And while this is slightly technical, recycling such products is unwise, because it means that the energy used to make them is lost. Re-use is the only viable sustainable option.
What this needs, therefore, is equipment which can be repaired, renovated, reconfigured, or rebuilt, when a change needs to be made. The metaphor, if you like, is Lego: parts which can be removed, replaced, or extended. It requires designers to rethink the entire production process and service model. I think this is a good thing. The technology industry was built by hackers. The change forced on it by high energy costs will be a return to its roots. And it will provoke some real, socially useful innovation.
