Concern 304 · Working draft · editorial review in progress
Fossil-fuel share of AI electricity
The fossil-fuel share of AI electricity is the portion supplied by burning coal, gas or oil.
Understanding the concern
An AI service uses the electricity available where and when its equipment runs. If extra demand is met by fossil-fuel plants, emissions can rise even when the equipment becomes more efficient. A company's clean-energy contract does not necessarily describe the power physically available during every hour of operation.
This is a question about the supply behind the socket. A busy service running overnight may face a different electricity mix from one running during a sunny afternoon. The climate effect depends on which generators supply the added demand, as well as the average mix. Local air pollution is another concern near fuel-burning plants.
An example
A new facility opens before the renewable project meant to supply it, leaving gas generation to fill the gap.
Illustrative unless identified as a documented case.
Words in plain English
- AI
- Software that learns patterns from examples or uses rules to perform tasks such as recognizing images or generating text. It can make mistakes and does not understand every situation as a person would.
Evidence and its limits
IEA analyses electricity supply; accounting guidance helps distinguish contractual claims from location-based electricity reporting.

Broader frameworks and background
These resources provide context. They do not establish every claim in this concern.
A question to discuss
Which sources supply the added demand now, and what changes when promised clean power arrives?

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?
