The same job can cost less carbon at a different hour.
Batch jobs, backups, CI and model retraining run at fixed times chosen years ago, regardless of how clean the electricity is.
The Green Software Foundation suggests running flexible jobs when the grid is cleaner. GreenCode draws on these patterns when it checks software.
GreenCode helps tackle this by holding its own heavy AI jobs for cleaner power. It also keeps its AI lean, with small fine-tuned models, retrieval so a model reads only what it needs, and each request routed to the smallest capable component. More on this.
The same job can cost less carbon at a different hour. Backups, test runs and model training often run at fixed times. Those times were often chosen years ago. They ignore how clean the electricity is right now. But the grid's carbon changes by the hour, and by region. Here is the fix you can use today. Find the jobs that can wait a few hours. Schedule them against a carbon forecast for your grid. In Great Britain, forecasts run more than ninety-six hours ahead. Keep your deadlines and service promises as hard limits. Emissions fall, with little effect on users. The Green Software Foundation suggests running flexible jobs when the grid is cleaner. GreenCode draws on these patterns when it checks software. GreenCode's Constitution skill can help an AI coding agent find waste like this. Then time the jobs using tools like the Carbon Aware SDK and Carbon Intensity API. GreenCode helps tackle this by holding its own heavy AI jobs for cleaner power. It also keeps its AI lean, with small models reading only what they need.
