 *   The allocation is done **based on electrical power**: we need to retrieve the electrical power dedicated to Block Storage:
     *   Retrieval of the estimation of the electricity consumption of the Block Storage servers –> [Handbook](https://handbook.scaleway.com/) (static data, like for Elastic Metal).

 To calculate the usage, we consider the French energy mix and the datacenter's PUE. In this example, they are O,056kgCo2e/kwh and 1,16, respectively. Which results in:
