Energy Is the Tax on Disposable Goods

By The Editor

Hold a €15 t-shirt in your hand and you are holding a settled argument about the price of energy.

The cotton, if there is any, was grown with diesel irrigation and harvested by machine. More likely it is polyester, which begins as crude oil, gets cracked into ethylene in a refinery, polymerized into resin, extruded into filament, and spun into thread. Every one of those steps is a furnace. The thread is knitted into fabric in a mill running on grid power, dyed in heated baths, cut, sewn in a factory eight thousand kilometers away, boxed, trucked to a port, loaded onto a container ship burning heavy fuel oil, unloaded in Rotterdam, trucked to a distribution center, trucked again to a store, and hung on a rack under lights that run sixteen hours a day.

The shirt costs €15. The labor in it costs almost nothing. The cotton or the oil costs a little. The thing that costs the most, hidden across every step, is energy.

For thirty years that energy was cheap. Because it was cheap, it was invisible. The €15 shirt was possible because each furnace, each ship, each truck, each warehouse light ran on power that nobody had to think about. The price of the shirt was the price of cheap energy, converted into a wearable form and sold at a margin.

That is the whole machine. A disposable good is a device for turning cheap energy into a product you throw away.

When energy stops being cheap, the machine does not adapt. It cannot. Its entire margin lives in the gap between cheap energy and a cheap product. When energy rises, the gap closes from both sides. The refinery costs more to run. The ship costs more to sail. The dye bath costs more to heat. The warehouse costs more to light. The €15 shirt becomes a €19 shirt, then a €23 shirt, and at no point does it become a better shirt. The added cost buys nothing. It only restores the margin that cheap energy used to provide for free.

This is why fast fashion gets more expensive without getting any good. The model was never about quality. The model was about converting cheap energy into volume. Take away the cheap energy and all that remains is the volume, now priced like quality without being quality.

The disposable economy was a bet that energy would stay cheap forever. The bet is being called.

Look at the durable object from the same angle and the numbers invert.

A merino wool shirt costs €120. It uses more energy per unit than the polyester shirt: wool is a more involved material. €120 buys real manufacturing. But the durable shirt is bought once and worn for ten years. The disposable shirt is bought, worn a dozen times, and replaced. Across ten years the polyester shirt becomes eight or ten polyester shirts, which means eight or ten trips through the furnace, eight or ten container voyages, eight or ten truckings, eight or ten end-of-life incinerations. The merino shirt is one of each.

Count the energy across the decade and the durable shirt wins by a wide margin. Fewer manufacturing runs. Fewer ships. Fewer trucks. Fewer disposals. The durable object was always the energy-efficient object. Nobody designed it that way. It happens because durability collapses ten transactions into one. Every transaction it removes is a furnace it never lights.

Energy efficiency by accident. The merino shirt was built to last, and lasting turned out to mean lighter on energy than the thing that was built to be thrown away.

There is a deeper reason the durable object holds. Quality stores energy in a form that does not decay.

The €120 merino shirt is dense with the energy that made it: the spinning, the knitting, the finishing. That energy is locked into the garment and released slowly, across a decade of wear, as use. The €15 polyester shirt holds the same kind of stored energy, but it releases it in eighteen months and then becomes waste. The waste holds the energy uselessly for two hundred years in a landfill. Both shirts are batteries of embodied energy. One discharges over a decade of use. The other discharges over a year of use and then sits inert for two centuries.

Buying durable is a way of refusing to waste the energy already spent. The furnace already ran. The ship already sailed. The only question is whether you get ten years out of that effort or eighteen months. Durability is the difference.

This reframes every purchase as a small position on the price of energy.

When you buy the disposable thing, you are betting that energy stays cheap: that the next shirt and the one after that will be affordable to manufacture and ship and replace. When you buy the durable thing, you are betting the opposite. You are betting that energy is expensive and getting more so, that the cost of the next manufacturing run is rising, and that the smart move is to buy the manufacturing once, at today's prices, and never pay for it again.

For three decades the disposable bet was the right one. Energy was cheap and stayed cheap. The man who bought ten cheap shirts paid less than the man who bought one good one. The numbers genuinely favored disposability, and the durable buyer was, in pure financial terms, slightly wrong.

He is not wrong anymore. The energy line under the disposable economy has moved. As it moves, every durable object bought at yesterday's prices becomes a better and better deal. The merino shirt bought in 2024 was manufactured with 2024 energy. The polyester shirts it replaces are being manufactured with this year's energy, and next year's, each one more expensive than the last. The durable buyer locked in his price. The disposable buyer pays the spot rate, forever.

None of this requires a forecast. It does not depend on energy going higher or staying high. It only depends on the structure, which is fixed: the disposable good is a high-frequency energy transaction. The durable good is a low-frequency one. Whatever energy costs, the object that requires it ten times is exposed to that cost ten times. The object that requires it once is exposed once.

In a world of cheap energy, that exposure barely mattered. Disposability won on price. In any other world, the exposure is the price, and durability wins. The man who owns one good shirt has insulated himself from the cost of making shirts. The man who owns a drawer of cheap ones is paying that cost on a loop he cannot get off.

Energy is the tax on disposable goods. It was always the tax. For thirty years the rate was set so low that nobody read the line on the receipt. The rate has changed. The line is now the largest number on the page.

The durable object was quietly avoiding that tax the entire time.
