Encouraging recycling is part of the low-tech approach to life. PxHere

It’s a popular idea that the path to sustainability lies in high-tech solutions. By making everyday items like cars electric, and installing smart systems to monitor and reduce energy use, it seems we’ll still be able to enjoy the comforts to which we’ve become accustomed while doing our bit for the planet – a state known as “green growth”.

But the risks of this approach are becoming ever clearer. Many modern technologies use materials like copper, cobalt, lithium and rare earth elements. These metals are in devices like cell phones, televisions and motors. Not only is their supply finite, but large amounts of energy are required for their extraction and processing – producing significant emissions.

Plus, many of these devices are inherently difficult to recycle. This is because to make them, complex mixes of materials are created, often in very small quantities. It’s very expensive to collect and separate them for recycling.

Among others, these limitations have led some to question the high-tech direction our society is taking – and to develop a burgeoning interest in low-tech solutions. These solutions prioritise simplicity and durability, local manufacture, as well as traditional or ancient techniques.

What’s more, low-tech solutions often focus on conviviality. This involves encouraging social connections, for example through communal music or dance, rather than fostering the hyper-individualism encouraged by resource-hungry digital devices.

“Low-tech” does not mean a return to medieval ways of living. But it does demand more discernment in our choice of technologies – and consideration of their disadvantages.

Origins of low-tech

Critics have proclaimed the downsides of excessive technology for centuries, from 19th century Luddites to 20th century writers like Jacques Ellul and Lewis Mumford. But it was the western energy crisis in the 1970s that really popularised these ideas.

British economist E.F. Schumacher’s 1973 book Small is Beautiful presented a powerful critique of modern technology and its depletion of resources like fossil fuels. Instead, Schumacher advocated for simplicity: locally affordable, efficient technologies (which he termed “intermediate” technologies), like small hydroelectricity devices used by rural communities.

Schumacher’s mantle has been taken up by a growing movement calling itself “low-tech”. Belgian writer Kris de Dekker’s online Low-Tech Magazine has been cataloguing low-tech solutions, such as windmills that use friction to heat buildings, since 2007. In particular, the magazine explores obsolete technologies that could still contribute to a sustainable society: like fruit walls used in the 1600s to create local, warm microclimates for growing Mediterranean fruits.

In the US, architect and academic Julia Watson’s book Lo-TEK (where TEK stands for Traditional Ecological Knowledge) explores traditional technologies from using reeds as building materials to creating wetlands for wastewater treatment.

And in France, engineer Philippe Bihouix’s realisation of technology’s drain on resources led to his prize-winning book The Age of Low Tech. First published in 2014, it describes what life in a low-tech world might be like, including radically cutting consumption.

Bihouix presents seven “commandments” of the low-tech movement. Among others, these cover the need to balance a technology’s performance with its environmental impact, being cautious of automation (especially where employment is replaced by increased energy use), and reducing our demands on nature.

But the first principle of low-tech is its emphasis on sobriety: avoiding excessive or frivolous consumption, and being satisfied by less beautiful models with lower performance. As Bihouix writes:

A reduction in consumption could make it quickly possible to rediscover the many simple, poetic, philosophical joys of a revitalised natural world … while the reduction in stress and working time would make it possible to develop many cultural or leisure activities such as shows, theatre, music, gardening or yoga.

Ancient solutions

Crucially, we can apply low-tech principles to our daily lives now. For example, we can easily reduce energy demand from heating by using warm clothes and blankets. Food, if it’s packaged at all, can be bought and stored in reusable, recyclable packaging like glass.

Architecture offers multiple opportunities for low-tech approaches, especially if we learn from history. Using ancient windcatcher towers designed to allow external cool air to flow through rooms lets buildings be cooled using much less energy than air conditioning. And storing heat in stones, used by the Romans for underfloor heating, is being considered today as a means of dealing with the intermittency of renewable energy.

Design and manufacture for sustainability emphasises reducing waste, often through avoiding mixing and contaminating materials. Simple materials like plain carbon steels, joined using removable fasteners, are easy to recycle and locally repair. Buses, trains and farm machinery using these steels, for example, can be much more readily refurbished or recycled than modern cars full of microelectronics and manufactured from sophisticated alloys.

In some places, the principles of low tech are already influencing urban design and industrial policy. Examples include “15-minute cities” where shops and other amenities are easily accessible to residents, using cargo bikes instead of cars or vans for deliveries, and encouraging repairable products through right-to-repair legislation in the EU and US.

Meanwhile, in Japan, there’s emerging interest in the reuse and recycling practices of the Edo period. From 1603 to 1867, the country was effectively closed to the outside world, with very limited access to raw materials. Therefore, extensive reuse and repair – even of things such as broken pottery or utensils with holes that we’d now regard as waste – became a way of life. Specialist repairers would mend or recycle everything from paper lanterns and books to shoes, pans, umbrellas and candles.

By following examples like these, we can make discerning technological choices a central part of our search for sustainable ways of living.

Capital in the Twenty-First Century
by Thomas Piketty. (Translated by Arthur Goldhammer)

In Capital in the Twenty-First Century, Thomas Piketty analyzes a unique collection of data from twenty countries, ranging as far back as the eighteenth century, to uncover key economic and social patterns. But economic trends are not acts of God. Political action has curbed dangerous inequalities in the past, says Thomas Piketty, and may do so again. A work of extraordinary ambition, originality, and rigor, Capital in the Twenty-First Century reorients our understanding of economic history and confronts us with sobering lessons for today. His findings will transform debate and set the agenda for the next generation of thought about wealth and inequality.

Nature's Fortune: How Business and Society Thrive by Investing in Nature
by Mark R. Tercek and Jonathan S. Adams.

What is nature worth? The answer to this question—which traditionally has been framed in environmental terms—is revolutionizing the way we do business. In Nature’s Fortune, Mark Tercek, CEO of The Nature Conservancy and former investment banker, and science writer Jonathan Adams argue that nature is not only the foundation of human well-being, but also the smartest commercial investment any business or government can make. The forests, floodplains, and oyster reefs often seen simply as raw materials or as obstacles to be cleared in the name of progress are, in fact as important to our future prosperity as technology or law or business innovation. Nature’s Fortune offers an essential guide to the world’s economic—and environmental—well-being.

Beyond Outrage: What has gone wrong with our economy and our democracy, and how to fix it -- by Robert B. Reich

In this timely book, Robert B. Reich argues that nothing good happens in Washington unless citizens are energized and organized to make sure Washington acts in the public good. The first step is to see the big picture. Beyond Outrage connects the dots, showing why the increasing share of income and wealth going to the top has hobbled jobs and growth for everyone else, undermining our democracy; caused Americans to become increasingly cynical about public life; and turned many Americans against one another. He also explains why the proposals of the “regressive right” are dead wrong and provides a clear roadmap of what must be done instead. Here’s a plan for action for everyone who cares about the future of America.

This Changes Everything: Occupy Wall Street and the 99% Movement
by Sarah van Gelder and staff of YES! Magazine.

This Changes Everything shows how the Occupy movement is shifting the way people view themselves and the world, the kind of society they believe is possible, and their own involvement in creating a society that works for the 99% rather than just the 1%. Attempts to pigeonhole this decentralized, fast-evolving movement have led to confusion and misperception. In this volume, the editors of YES! Magazine bring together voices from inside and outside the protests to convey the issues, possibilities, and personalities associated with the Occupy Wall Street movement. This book features contributions from Naomi Klein, David Korten, Rebecca Solnit, Ralph Nader, and others, as well as Occupy activists who were there from the beginning.
