There's a concept in physics that applies just as well to organisations: energy can't be created from nothing. It can be transformed. It can be directed. But if the source runs dry, everything slows down.
In professional contexts, we rarely talk about energy this way. We talk about productivity, motivation, engagement. But underneath all of these is something more fundamental: the capacity of people — and teams — to sustain performance over time without depleting themselves.
The inner battery: a useful metaphor
Think of every person as carrying an inner battery. It charges and discharges through the day, the week, the project cycle.
What charges it varies between people. For some, it's creative work. For others, it's social interaction, or deep focus, or visible impact. For others still, it's rest, physical activity or simply feeling that their contribution is recognised.
What discharges it also varies. Pointless meetings. Ambiguous requests. Lack of autonomy. Constant urgency with no real priority. Feeling unheard. Role conflicts. Chronic uncertainty.
The problem isn't that batteries run low — that happens to everyone. The problem is not knowing what recharges them. And not creating the conditions in which recharging is actually possible.
What this means for team performance
A team's collective energy level is one of the most accurate predictors of its sustainable performance — and one of the least measured.
When teams operate consistently below their energy threshold, several things happen: creativity drops. Tolerance for ambiguity shrinks. Communication becomes more defensive. Errors increase. People do what's needed to get through the day rather than what would genuinely add value.
None of this shows up clearly in a dashboard. But it shows up in the quality of decisions, in the texture of conversations, and in the rate at which people disengage or leave.
The manager's role
Managers affect team energy more than almost any other factor — often without realising it.
A manager who is constantly stressed transmits stress. A manager who interrupts rest cycles with weekend messages erodes recovery. A manager who doesn't prioritise forces the team to manage everything as equally urgent — which is exhausting.
Conversely, a manager who is clear about priorities, who protects the team's focus time, who acknowledges effort as well as results, who creates conditions for genuine recovery — that manager multiplies available energy rather than consuming it.
This isn't soft management. It's one of the most concrete levers for sustainable performance.
Awareness before intervention
Before trying to "fix" team energy, it's worth developing better awareness of where things stand.
Some useful questions: What drains energy most in this team right now? Which activities, meetings or dynamics feel like they cost more than they contribute? When does the team seem most engaged and effective — and what's different in those moments?
These questions don't require a survey or a formal process. They require attention, and a willingness to hear honest answers.
Sustainable performance isn't a byproduct of working harder
The pressure to do more with less, faster, with fewer resources, is a constant in most organisations. It's real, and it's not going away.
But the organisations that sustain high performance over time aren't the ones that extract the most from people in the short run. They're the ones that understand how human energy actually works — and build the conditions that keep it available.
That's not idealism. It's what the evidence on burnout, turnover and team effectiveness consistently points to.
