 The objective of this extension is to display power usage of the CPU and/or GPU on which jupyter server is running. Power usage is estimated using [Running Average Power Limit (RAPL)](https://web.eece.maine.edu/~vweaver/projects/rapl/) metrics that are available on Intel processors manufactured after 2012 (since broadwell). It is available on latest AMD processors as well. For the case of GPUs, currently only nVIDIA GPUs are supported and power usage is gathered from `nvidia-smi` tool.
 
-Additionally, the extension is capable of estimating equivalent CO<sub>2</sub> emissions. Emissions are estimated based on the current power usage and a emission factor that gives equivalent grams of CO<sub>2</sub> power consumed. Currently, the extension supports fetching real time emission factor from [RTE eCOCO<sub>2</sub> mix (only for France)](https://www.rte-france.com/en/eco2mix/co2-emissions) and [Electricty Maps](https://www.electricitymaps.com/?utm_source=api-portal.electricitymaps.com&utm_medium=referral) that provides factor for a lot of countries. If neither RTE eCoCO<sub>2</sub> mix nor Electricity Maps can be used, a constant configurable emission factor is available to use. Actually a [value of 475 gCO<sub>2</sub>.eq/kWh](https://arxiv.org/pdf/2306.08323.pdf) is used as default for this constant factor.

 The metrics are displayed in the top bar of JupyterLab and are updated at a configurable interval. The default interval is 5 seconds. RAPL can enforce power limit so as nVIDIA GPUs. If those power limits are enabled and available, they will be displayed in the indicators.
