Energy is the condition we feel most acutely and potentially understand the least.

We talk about it constantly; having it, lacking it, conserving it, managing it. Low energy is treated as a personal problem, a sign of imbalance, poor habits, or insufficient resilience. High energy is praised as a marker of vitality, ambition, and competence.

And yet the widespread experience of depletion today is too consistent to be explained individually.
Like truth, time, and attention, energy has a history. And the way it is now demanded, measured, and exhausted is not accidental.

Energy has not diminished. It has been redefined.

For most of human history, energy was understood as finite, embodied, and variable.

It rose and fell with seasons, health, age, and circumstance. Periods of intensity were followed by periods of rest. Effort was shaped by necessity and meaning rather than by continuity. Fatigue was not a failure of character; it was a signal.

Crucially, energy was not expected to be consistent.

Human capacity was assumed to fluctuate, and social structures absorbed much of that variation. Energy was buffered by shared rhythms, collective pauses, and limits that were external rather than internalised.

To be tired was ordinary. To stop was permitted.

The nineteenth century introduces a profound shift.

With industrialisation, energy becomes abstracted from the body and reconceived as output. Machines establish a new baseline: continuous operation, predictable performance, minimal recovery. Human labour is increasingly measured against this standard.

In this context, energy is no longer capacity. It is throughput.

The language of energy begins to align with productivity, efficiency, and yield. The expectation emerges that effort should be steady, repeatable, and scalable.

Thinkers like Karl Marx identify the implications clearly: human labour power is treated as a resource to be extracted, quantified, and consumed. Energy is no longer something people have. It is something systems use.

From this point on, fatigue acquires moral weight. To be depleted is to fall behind.

As with time and attention, the most consequential shift is not mechanical but psychological.

Over the twentieth century, expectations of sustained output move inward. People begin to manage their own energy in service of external demands. Rest becomes conditional. Recovery must be justified.

Energy is no longer something that fluctuates naturally. It becomes something that should be optimised.

The rise of management theory, performance metrics, and later self-management culture reframes energy as an individual responsibility. If output drops, the solution is not structural change but personal adjustment.
This is where energy quietly detaches from meaning.

Effort is required regardless of purpose. Consistency is valued over sustainability.

In the late twentieth and early twenty-first centuries, this logic intensifies.

Traditional boundaries that once shaped energy; working hours, weekends, seasonal variation, clear endings, weaken. Flexibility promises freedom but often removes the very structures that limited extraction.

Energy is now expected to be continuously available, emotionally regulated, cognitively engaged, physically reliable.

The body is treated as if it were endlessly adaptable.

At the same time, recovery is increasingly privatised. Sleep, exercise, nutrition, and rest are framed as individual optimisation strategies rather than collective necessities. Energy must be restored off the clock in order to remain usable on it.

Exhaustion becomes normalised. Burnout becomes familiar. Low-grade depletion becomes a background condition.

Energy has not disappeared. What has changed is the permission to be finite.

Where earlier forms of life assumed fluctuation, recovery, and decline, contemporary systems reward consistency and penalise pause. Energy is valued most when it is invisible, when it does not interrupt output.

Like truth, time, and attention, energy is no longer something that holds us. It is something that is quietly taken for granted.

Perhaps the question is not how to have more energy, but how to recognise what human energy actually is; embodied, uneven, responsive, and limited.

Not a resource to be extracted. But a condition that makes life possible at all.

What is striking about contemporary discourse on energy is how often systemic depletion is misnamed as personal failure.

People are told to manage their energy better, build resilience, improve habits and optimise routines.
What is rarely acknowledged is that the demands placed on human energy have expanded beyond what most bodies can sustain, especially when attention is fragmented and time is compressed.

The problem is not that people are weak. It is that the conditions of contemporary life assume limitless capacity.

Energy has been abstracted from the body, detached from rhythm, and separated from meaning and then treated as if it were infinitely renewable.
