  • Brazil: Powered predominantly by hydroelectricity, Brazil's grid is highly renewable, with over 80% of its energy from clean sources.
  • Canada - Quebec Quebec's grid is nearly 100% renewable, thanks to extensive hydropower infrastructure.
  • France: France's grid is largely low-carbon, driven by a mix of nuclear and renewable energy sources.
  • Spain (winters only) During winters, wind and hydro dominate Spain's energy mix, significantly increasing renewable contributions.
  • Sweden: Sweden's grid is over 95% renewable, powered by hydro, wind, and nuclear energy.
  • New Zealand: With geothermal and hydropower leading the way, New Zealand's grid is over 80% renewable.
  • Norway: Norway's grid is nearly 100% renewable, thanks to abundant hydropower.
  • USA (Seattle) Seattle benefits from Washington state's hydro-rich grid, making it over 90% renewable.

Seamless Workload Distribution

One of the key benefits of operating across multiple regions is the ability to spread workloads efficiently:

  • No More Long Queues: By distributing jobs to regions with free and available servers, we minimize delays and keep your workflows moving smoothly.
  • Reliability at Scale: Even during peak times, our multi-region approach ensures high availability, so your jobs are always prioritized.

Blink and you'll miss it!

Worried about latency? Don’t be. CarbonRunner ensures that even when your jobs are run across the globe, the latency is virtually unnoticeable. In fact, it’s typically faster than the time it takes to blink—just 250ms or less.

This means you get a seamless experience without compromise, all while contributing to significant carbon savings.
