Being an independent journalist – or an office worker if you wish – I always reasoned that I needed a decent computer and that I need to pay for quality. Between 2000 and 2017, I consumed three laptops that I bought new and which cost me around 5,000 euros in total – roughly 300 euros per year over the entire period. The average useful life of my three laptops was 5.7 years.
In 2017, somewhere between getting my office, I decided not to buy any more new laptops. Instead, I switched to a 2006 second-hand machine that I purchased online for 50 euros and which does everything that I want and need. Including a new battery and a simple hardware upgrade, I invested less than 150 euros.
If my 2006 laptop lasts as long as my other machines – if it runs for another 1.7 years – it will have cost me only 26 euros per year. That’s more than 10 times less than the cost of my previous laptops. In this article, I explain my motivations for not buying new laptops, and how you could do the same.
Energy and material use of a laptop
Not buying new laptops saves a lot of money, but also a lot of resources and environmental destruction. According to the most recent life cycle analysis, it takes 3,010 to 4,340 megajoules of primary energy to make a laptop – this includes mining the materials, manufacturing the machine, and bringing it to market. 1
Each year, we purchase between 160 and 200 million laptops. Using the data above, this means that the production of laptops requires a yearly energy consumption of 480 to 868 petajoules, which corresponds to between one quarter and almost half of all solar PV energy produced worldwide in 2018 (2,023 petajoules). 2 The making of a laptop also involves a high material consumption, which includes a wide variety of minerals that may be considered scarce due to different types of constraints: economic, social, geochemical, and geopolitical. 34
The production of microchips is a very energy- and material-intensive process, but that is not the only problem. The high resource use of laptops is also because they have a very short lifespan. Most of the 160-200 million laptops sold each year are replacement purchases. The average laptop is replaced every 3 years (in business) to five years (elsewhere). 3 My 5.7 years per laptop experience is not exceptional.
Laptops don’t change
The study cited dates from 2011, and it refers to a machine made in 2001: a Dell Inspiron 2500. You are forgiven for thinking that this “most recent life cycle analysis of a laptop” is outdated, but it’s not. A 2015 research paper discovered that the embodied energy of laptops is static over time. 5
The scientists disassembled 11 laptops of similar size, made between 1999 and 2008, and weighed the different components. Also, they measured the silicon die area for all motherboards and 30 DRAM cards produced over roughly the same period (until 2011). They found that the mass and material composition of all key components – battery, motherboard, hard drive, memory – did not change significantly, even though manufacturing processes became more efficient in energy and material use.
The reason is simple: improvements in functionality balance the efficiency gains obtained in the manufacturing process. Battery mass, memory, and hard disk drive mass decreased per unit of functionality but showed roughly constant totals per year. The same dynamic explains why newer laptops don’t show lower operational electricity consumption compared to older laptops. New laptops may be more energy-efficient per computational power, but these gains are offset by more computational power. Jevon’s paradox is nowhere as evident as it is in computing.
The challenge
All this means that there’s no environmental or financial benefit whatsoever to replacing an old laptop with a new one. On the contrary, the only thing a consumer can do to improve their laptop’s ecological and economic sustainability is to use it for as long as possible. This is facilitated by the fact that laptops are now a mature technology and have more than sufficient computational power. One problem, though. Consumers who try to keep working on their old laptops are likely to end up frustrated. I shortly explain my frustrations below, and I’m pretty confident that they are not exceptional.
