Worker Node Setup of DownToZero
created: Monday, Sep 23, 2024
Last year we already did a blog post on the hardware setup of DownToZero. Since then we are using the same setup for a while now and wanted to share an update.
Energy consumption
Since we decided to purely use notebook chips, our energy consumption is significantly lower then desktop machine. Also our mode to only power the machine during times that solar power is available lead us to near zero power grid consumption.
On a per node basis we currently consume about 1.4 kWh idle per month, with our current load mix about 2kWh per month.
| Month | Consumed Energy in kWh |
|---|---|
| September 2023 | 2.1 |
| October 2023 | 2.383 |
| November 2023 | 1.807 |
| December 2023 | 1.4 |
| January 2024 | 1.389 |
| February 2024 | 1.65 |
| March 2024 | 1.528 |
| April 2024 | 1.521 |
| May 2024 | 1.62 |
| June 2024 | 1.81 |

energe consumed over the last 12 months with a 40 watt baseline
To give you some comparison, we added a machine with average energy consumption of about 40 watts.
We see this as confirmation that building out stack on top of mobile CPUs is worth the effort an money.
