The problem

Sites with on-site renewables often run controllable loads at fixed times, buying grid power while their panels export or sit idle.

The fix you can use today

• Split loads into controllable and non-controllable.
• Schedule the controllable ones into hours of on-site generation.
• Set limits on how far a job may move, and measure the impact on users.

GreenCode researchers found that moving flexible data centre work to match solar power cut energy costs by 16.64%.

Tools that help

• Carbon Aware SDK (Green Software Foundation): an API and CLI for grid carbon-intensity data, so flexible work can move to cleaner times or places
• Electricity Maps: live and forecast grid carbon intensity by region

How GreenCode helps

GreenCode helps tackle this by mapping your running systems and attributing energy and CO2e to the services that cause it. You see which services run hot, and which barely run at all, before you decide what can move. More on this.
