Concern 310 · Working draft · editorial review in progress
Standby and idle power
Standby and idle power is electricity used by computing equipment that is switched on but doing little useful work.
Understanding the concern
Servers often stay ready to respond quickly, even between requests. They still need power, and the building may still need cooling. A large cluster with low use can therefore have a substantial running cost that is not obvious from the number of completed tasks. Spare capacity can improve reliability, but it has a cost.
A nearly empty bus still uses fuel on its route. Filling more seats improves the energy used per passenger without changing the bus itself. In a similar way, sharing computing resources and turning down unused capacity may improve efficiency. The challenge is to save energy while keeping enough room for sudden demand or equipment failures.
An example
A service reserves a large group of servers for occasional peaks and leaves most of them waiting overnight.
Illustrative unless identified as a documented case.
Evidence and its limits
These studies include infrastructure and utilisation effects; the bus is an original analogy, not a measured claim.

A question to discuss
How much power goes to useful work, and how much keeps unused capacity ready?

Virtues and principles to consider
Virtues are qualities we practice in how we treat people and make choices. They are not scores for judging someone. Use these ideas to explore what a thoughtful response could look like.
Stewardship
Stewardship means caring for resources and systems that others depend on, including people who will use them later. It looks beyond the benefit of a quick launch.
Plan for maintenance, energy use, data protection, and eventual shutdown. Ask who will look after the tool when the original team moves on and how future users can avoid inheriting hidden costs.
Ask together: What are we responsible for caring for over time?
Justice
Justice means fair treatment, fair procedures, and attention to who receives benefits and burdens. It asks whether people with less power can be heard and seek repair.
Look at outcomes across different groups and individual cases. Provide a usable way to challenge decisions and correct harm. Equal wording in a policy does not guarantee equal treatment in practice.
Ask together: Who benefits, who bears the cost, and who can challenge the decision?
Reading reality
Reading reality means looking closely at the situation people actually face. A visible problem may be connected to habits, incentives, or rules beneath the surface.
If an AI tool gives a poor result, look at the task, data, workplace pressures, and available support. Do not assume that changing the software alone will solve the problem.
Ask together: What is happening here, and what conditions help explain it?
