Hi guys!
I like to share some of my thoughts on electrical energy transfer (EET). I classify five different types of EET. Four of them are HOT FLOW, and one is COLD. An example is also presented on how to charge a mobile device wirelessly. These are just ideas. Just think about it more. Perhaps you can improve it further. Good luck and enjoy!

 

1&2 are charge carrier (current electricity) flows not electrical energy transfers.

I'm not sure #5 exists. I notice you didn't give examples.

#3 and 4 and simple transformers and capacitive coupling, such as goes on within any electronic device.

 

Transfer of energy occurs when there is a conversion. #3 and 4 are coupling techniques, not transfer techniques, and I don't think electric flow is an energy transfer, but pure energy being expressed. One definition of energy and work is motion.

Converting a electric current, such as RF, into photons is a transfer.

A battery converting chemical energy into electrical energy is a transfer.

A generator converting motion or mechanical energy into electrical energy (or a motor doing the opposite) is a transfer.

It is semantics, but language is important.
