What is Carbon Aware software?

Carbon Aware software optimizes for clean energy, either by time or location, shifting the work to when or where the energy is clean on a particular grid.

Join us at the hack

We’ll be taking part – will you? Balanced skills teams will be essential to create superb Carbon Aware solutions, so this is definitely not just for engineers. You can take part as a team (max five people), or sign up as an individual with skills to offer teams, and seek matches. There’s no application fee and teams will be provided with mentors if required, and WattTime licenses for the duration of the hack to enable them to use the SDK.

What to build

Project submissions must leverage the Green Software Foundation’s Carbon Aware SDK to create carbon aware software, or to create enhanced capabilities for the Carbon Aware SDK. Projects can be written in any language capable of connecting to the Carbon Aware SDK API. That would likely include code, but it is not limited to it. We encourage participation of any type as we are looking for creative and innovative solutions to green software. There are many areas to explore.
