One of the main problems of PoW networks like Bitcoin or Ethereum is its energy consumption.
Question 1: does this get solved with PoA networks?(without taking in account that these are not really suitable for public networks).
Question 2: are there any comparisons between PoW and PoA out there that look into the numbers, in terms like computational or environmental/energetic cost? For example, between an ethereum PoW blockchain and a PoA one. I haven't been able to find any.
