This first experiment to guarantee the renewable origin of the energy supplies was done with the financial entity Kutxabank, which was able to track, in real time, the origin of the energy supplied by Iberdrola from the generation asset to the point of consumption, Iberdrola said in a press release.
It would be interesting to see how this really works. I mean all the following steps are understandable, but what about the very first input? How we can be sure that those guys who claim their energy is renewable are telling the truth without trusting them?
If they are going to establish a hierarchy of priorities based on sources of origin for consumers, wouldn't it be tempting to lie about the sources?
