The open source repository for Electricity Maps App and data parsers that enables a real-time visualisation of the CO2 emissions of electricity consumption
Role in this project:
Back-end Developer
Back-end DeveloperContributions:57 commits, 88 PRs, 116 pushes in 2 years 4 months
Contributions summary:Bruno primarily contributed to the project by modifying the `co2eq_parameters.js` and `config/co2eq_parameters.js` files, indicating a focus on refining the data used to calculate CO2 emissions. They added, updated, and corrected carbon intensity factors for various energy sources and countries. Furthermore, the user implemented changes related to parsing and data acquisition from external sources like Statnett and Entsoe, along with fixes for various parsers. Their work involved adjusting data processing logic and integrating external data into the application.
