IIRC lightning network transactions only use as much electricity as 10 emails, although I guess at some point a real Bitcoin transaction will happen eventually.
Yeah pretty much. A lightning channel is a bit like putting money down as a retainer for a lawyer, or putting a deposit down in a hotel.
The real transaction happens at the beginning, and another transaction happens at the end when the channel closes and we settle out who gets the remainder.
