Proof of stake has no mining, no datacenters. If proof of stake ends up working it would probably be almost as effective as Visa currently is. Visa is always going to be more efficient due to it's centralized nature. Currently one bitcoin transaction uses the same amount of energy as driving a tesla 2000 miles, so POS is quite an improvement.

Proof of stake still requires cryptographic validation of each block by each node, so it uses much less energy than PoW, but not none. I think "no miners, still (distributed) datacenters" would be more accurate.

Proof of stake is not secure, there is no way to recover from a 51% attack. Proof of work and proof of space are much better.
