This data collection was created for the following reason.
“Gorona del Viento” had not published any traceable data about the combined wind and hydropower plant on El Hierro until early 2019.
Unfortunately unrealistic information was disseminated by “Cabildo de Hierro”, the island Government and owner of Gorona del Viento.
Then i stumbled over the -> Blog of Roger Andrews where i could find some base data.
I myself was often on the island, so i started to collect frequency data on site and published it.
For this I used a non-calibrated frequency measuring device called “Mutatio” thanks to Damian Schneider in our house on El Hierro.
Also i collected data as far as possible on site.
These are documented in the Cloud “GDV/Field-studies-JJJJ-MM-DD”.
Since 2019 -> “Gorona del Viento” publish data here:

The side

shows that CO2 per kwh is more en El Hierro than in Spanish Mainland or Germany since 2019 till now.
Everybody can make his own mind up with that information……
