i believe that energy will not be cheap to measure, since all forms of energy require investment and at the end of the day there are more and more users, companies and connected equipment that require energy for their use, almost everything is connected to that network, social life is currently supported by energy, therefore it will always have to give a commission for it. comparing internet data is smart and can in my case give me an idea of how important it is, since servers and internet services need energy to function and it must be paid or fed back. energy in any form will always ask for a payment no matter how low it is. to some extent the primary source will get its interest. thanks for sharing and sats to all.
